PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the invention and the manner in which it is to be performed:
FIELD OF THE INVENTION
The present invention relates to the field of energy storage devices, particularly electrochemical cells. More particularly, the present invention relates to a multi-dimensional electrode architecture based electrochemical cell that provides higher volumetric and gravimetric energy density.
BACKGROUND OF THE INVENTION
An electrochemical cell is a fundamental component of many electrochemical systems and experiments. It comprises of two primary elements: electrodes and an electrolyte solution. Electrodes are typically made of conductive materials, such as metals, carbons or any other materials with conductive network, and they play a pivotal role in these cells. There are two distinct types of electrodes in an electrochemical cell: the anode and the cathode.
The anode is where the process of oxidation takes place. During oxidation, electrons are released from the anode into the external circuit. This flow of electrons is a crucial aspect of many electrochemical reactions. In contrast, the cathode is where reduction occurs. Reduction involves the gain of electrons, and at the cathode, electrons from the external circuit are consumed in this process.
Complementing the electrodes, the second essential component of an electrode cell is the electrolyte. The electrolyte is a solution or substance that serves as a medium for the movement of ions between the anode and cathode. These ions are actively involved in the electrochemical reactions happening at the electrodes. By facilitating the transfer of charge within the cell, the electrolyte enables the overall functioning of the electrode cell.
The conventional cell manufacturing, the process involves the utilization of two-dimensional porous thin film electrodes that are applied onto a metal foils. The procedure commences by preparing a liquid slurry using active electrode materials, conductive additives, and binders. Subsequently, this slurry, referred to as the anode slurry, is deposited onto a thin copper (Cu) or aluminium (Al) foil. Similarly, the cathode slurry is coated onto a thin aluminium (Al) foil or a comparable metal surface.
Following the electrode coating, these sheets are cut into specific dimensions tailored to the particular cell design and desired form factors. These form factors can vary and include cylindrical cells, pouch cells, and prismatic cells. After achieving the desired dimensions, a thin, porous polymeric separator membrane is inserted between the cathode and anode sheets. This configuration, featuring the 2D electrodes and separator membrane, is either wound around a cylindrical mandrel for cylindrical cells or stacked or wound onto a flat mandrel for pouch or prismatic cells, forming the core of the cell. This manufacturing process is integral to the production of conventional cells used in various applications.
The conventional 2D electrode stack architecture in cells is not without its drawbacks. Firstly, the use of copper (Cu) and/or aluminium (Al) foils as both substrates and current collectors within the electrodes adds bulk to the cell, ultimately reducing its energy density. Furthermore, these metal foils contribute significantly to the overall weight of the cell, negatively impacting its gravimetric energy density.
Secondly, the electrical connections of tabs in this construction are intricate, and the lengthy path that current must travel through these tabs results in high electrical resistance. This elevated resistance concentrates the flow of current at the tabs, leading to localized heat generation near them, which, in turn, accelerates the degradation of the cell.
Moreover, due to the inherent higher electrical resistance of tabs and metal foils, the cells tend to heat up significantly during operation. Consequently, the layer-wise arrangement of electrode sheets accumulates excess heat at the centre of the cell, resulting in elevated temperatures that hasten cell degradation.
Additionally, the layered cell core design, with alternating polymeric separator membranes, impedes thermal conductivity across the core's thickness, causing heat dissipation to occur at a slower rate. These temperature-related issues, including cooling rates and heat concentration, place limitations on the cell's lifespan and its ability to be charged at higher rates. Moreover, the conventional 2D electrode stack architecture presents several disadvantages related to energy density, electrical resistance, localized heat generation, and overall cell longevity.
KR20130021784A discloses an electrode assembly, a pouch, and an electrolyte solution-containing structure however the assembly process itself can be quite complex due to the need to coordinate the positioning of multiple electrode plates and separators. This complexity may result in increased manufacturing costs and potential assembly errors. Additionally, the presence of multiple components and layers within the assembly could introduce the risk of internal shorts or other operational issues, impacting the overall reliability of the system.
US8277970B2 discloses a pouch-shaped secondary battery having a non-sealing residue portion, and, more particularly, to a secondary battery including an electrode assembly mounted in a pouch-shaped battery case in a sealed state, wherein a residue portion, which is not sealed (non-sealing residue portion), is defined between a sealing portion of the battery case and the electrode assembly for collecting generated gas, and the non-sealing residue portion is formed at the outside of an electrode assembly receiving part adjacent to the one-side sealing portion. However, the introduction of a non-sealing residue portion, while intended for gas collection, adds intricacy to both the battery's overall structure and its assembly process. This complexity can lead to higher manufacturing costs and may increase the likelihood of errors or defects during production, potentially impacting the battery's reliability and safety. Additionally, the presence of a non-sealing residue portion could render the battery more challenging to package and integrate into various applications, as the unconventional construction may not fit seamlessly into existing battery compartments or configurations. This limitation constrain the versatility and adoption of the battery in different devices or systems.
Therefore, there is a need of a modified electrode cell that solves the issues faced in the conventional construction.
OBJECT OF THE INVENTION
The main object of the present invention is to provide a multi-dimensional electrode architecture based electrochemical cell that provides inherently higher volumetric and gravimetric energy density.
Another object of the present invention is to provide a multi-dimensional electrode architecture based electrochemical cell which eliminates the need for metallic substrates for achieving higher volumetric and gravimetric energy density.
Yet another object of the present invention is to provide a multi-dimensional electrode architecture based electrochemical cell in which the cell stack construction realigns the flow of current across the terminals such that the path length is much shorter and the current is spread across a wider cross-sectional area, which leads to significant reduction in heat generation.
Yet another object of the present invention is to provide a multi-dimensional electrode architecture based electrochemical cell that eliminates the need of tabs.
Still another object of the present invention is to provide a multi-dimensional electrode architecture based electrochemical cell in which the heat generation itself is significantly reduced due to absence of tabs.
SUMMARY OF THE INVENTION
The present invention relates to a multi-dimensional electrode architecture based electrochemical cell with the primary objectives of achieving higher energy density, eliminating the need for metallic substrates, and reducing heat generation, achieves a shorter current path and broader current distribution, resulting in decreased heat generation. Additionally, it eliminates the need for tabs, simplifying the construction and further reducing heat generation.
In an embodiment, the present invention provides a multi-dimensional electrode architecture based electrochemical cell comprising of a plurality of layer which include a lower current collector layer, an anode layer, a separator layer, a cathode layer, an adhesion layer, and an upper current collector layer.

The separator layer facilitates a flow of lithium ions between the anode and cathode layers, but prevents passage of electrons, thereby preventing electric short circuits. The blind holes are subsequently filled with a pin-shaped cathode material. Additionally, the adhesion layer is applied to the upper surface of the cathode layer, and the conductive layer serves as the upper current collector, positioned atop the adhesion layer.

In an implementation, the anode layer (1) not only acts as the electrode but also interact with a surrounding material such as electrolyte. Further, in another implementation, dimensions and structure of the anode layer (1) is not limited and may vary according to the requirements. The anode layer (1) facilitates in a flow of a set of ions into the multi-dimensional electrode architecture based electrochemical cell (100) and said anode layer (1) includes a plurality of blind holes that increases the flow of the set of ions. Also, in an implementation, the anode layer (1) has a pin shaped structure and the cathode layer (3) has a plurality of blind holes.

In an implementation, the upper current collector layer (5) and the lower current collector layer (6) do not participate in the electrochemical reaction, but facilitates in a flow of electricity in the multi-dimensional electrode architecture based electrochemical cell. In another implementation, the upper current collector layer (5) and the lower current collector layer (6) are made up of a highly conductive material such as copper, aluminum, or other conductive substrates which provides high electrical conductivity and chemical stability.
The arrangement of layers in the multi-dimensional electrode architecture based electrochemical cell is not limited to any specific configuration or sequence. Various alternative arrangements and combination of layers are within the scope of the present invention. Figure 1 is illustrative and do not restrict the arrangement of layers.

Further, a bottom portion of the blind hole allows the separator layer (2) to form at the bottom as well, thus preventing the cathode pins from touching the current collector layer (5) at the bottom of a stack and causing a short-circuit. The stack is obtained after placement of the all the layers of the multi-dimensional electrode.
In an implementation, the blind holes are cylindrical or conical cavities drilled or formed in the anode layer (1). The blind holes prevent the cathode pins from reaching or piercing the anode layer (1), thereby preventing any potential short circuit or misalignment with the multi-dimensional electrode architecture based electrochemical cell.

Figure 2 is a sectional view of the multi-dimensional electrode architecture based electrochemical cell according to an embodiment of the present invention and Figure 3(b) and Figure 3(c) are cross-sectional views of the multi-dimensional electrode cell according to an embodiment of the present invention.
The present invention does not require metallic substrates and hence offers a higher volumetric and gravimetric energy density, further the reconfiguration of current flow pathways across the cell (100) terminals shortens the path length, while simultaneously facilitating its distribution across a vastly expanded cross-sectional area. The consequence of this feature is the s reduction in the generation of heat during the operation of the cell (100).

The insulator cap (7) is an optional part in the multi-dimensional electrode architecture based electrochemical cell (100).
In an implementation, the above mentioned architecture of multi-dimensional electrode architecture based electrochemical cell (100) is reversible for the anode layer (1) and the cathode layer (3). Both of the configurations are used conveniently using rest of the, i.e. the cathode layer (3) has blind hole architecture and the anode layer (1) has pin shaped architecture.
EXAMPLE 1
Exemplary Working of multi-dimensional electrode architecture based electrochemical cell
The present invention provides a multi-dimensional electrode architecture based electrochemical cell with prolonged life and fast charging capacity which is achieved by eliminating metallic substrates, optimizing current flow pathways, and eradicating the need for tabs.
In a charging process, a set of Li-ions are released out of the cathode active material crystal lattice structure (i.e. cathode layer (3)) along with an equal number of electrons. The Li-ions enter into a electrolyte phase that fills the pores of the cathode layer (3), separator layer (3) and the anode layer (1), thus providing a continuum for the ions to transport across the stack. The electrons on the other hand, cannot travel through the electrolyte and travel through the network of conductive additives through to a plurality of terminals from where the ions enter into an external circuit.
The Li-ions travel across the separator layer (3) through the electrolyte and reach a surface of the anode layer (1).
The electrons travel through the external circuit to the other terminal, from there the electrons travel through the conductive additive network that is spread through the anode layer (1) and thus reach the surface of the anode layer (1). Thereafter, the Li-ions and electrons recombine at the surface of the anode layer (1) and enter an anode lattice structure of the anode layer (1).
Further, during a discharging process, a reverse process occurs. Further a three dimension architecture in the present invention changes a geometry of the cell stacks from flat layers, to interlocked cathode pins in a honeycomb shaped anode matrix with a ceramic separator layer in between. Further three dimension architecture modifies the geometry of the pathways of the electrons and ions. The mechanism of transport remains the same.
EXAMPLE 2
Exemplary implementation of multi-dimensional electrode architecture based electrochemical cell
The present invention provides the multi-dimensional electrode architecture based electrochemical cell. Further, all the layers of the present invention are affixed on to each other either by pure mechanical contact (i.e., pressure) or via deposition.
The anode layer (1) is fixed on the lower current collector layer (6) via an application of suitable amount of pressure. The separator layer (2) is affixed on the anode layer (1) via deposition (e.g., via slurry casting/slip casting/spraying/coating etc. The cathode layer (3) is affixed purely by insertion and held in place via interlocking geometry (friction prevents relative motion between separator layer (2) and cathode layer (3)).
Thereafter, the upper current collector layer (5) is connected to the cathode pins with a carbon glue layer via an application of suitable amount of pressure. The multi-dimensional electrode architecture based electrochemical cell (100) comprises an insulator cap (7) for providing an insulation between the anode layer (1) and the cathode layer (3).
EXAMPLE 3
Experimental Analysis
The present invention provides the multi-dimensional electrode architecture based electrochemical cell with prolonged life and fast charging capacity which is achieved by eliminating metallic substrates, optimizing current flow pathways, and eradicating the need for tabs.
Further, a conventional cell designs employ copper and aluminium foils as substrates for coating electrode layers, which account for about 20-25% of the cell mass. In the present invention, there is no need for these metal foils as substrates, thus, energy density is increased potentially by 25-33%.
The present invention improve cycle life of batteries significantly as the battery cell degradation in Li-ion batteries is primarily dominated by electrolyte degradation or participation of electrolyte molecules in parasitic reactions. Like all reactions, these parasitic reactions require energy, which is provided during the charging process in form of heat. With a 10 fold reduction in resistance, the heat generation also reduces to 1/10th, thereby potentially reducing the extent of parasitic reactions and hence cell degradation. Thus, potentially, the cycle life of the multi-dimensional electrode architecture based electrochemical cell of the present invention is extended upto 10 times.
Therefore, the present invention provides a multi-dimensional electrode architecture based electrochemical cell with prolonged life and fast charging capacity which is achieved by eliminating metallic substrates, optimizing current flow pathways, and eradicating the need for tabs.
