DESC:FIELD OF THE INVENTION
The present invention relates to the field of composites. More particularly, the present invention relates to an electrically conductive composite to improve the percolation network of conductive components across the electrode and a method of preparation thereof.

BACKGROUND OF THE INVENTION
A cell refers to the basic electrochemical unit that produces electrical energy through chemical reactions. The cells include lithium-ion cells, sodium-ion cells alkaline cells and lead-acid cells. A cell consists of three parts, anode, cathode and electrolyte. The anode and cathode are the negative and positive electrodes of the electrochemical cell respectively. Electrode fabrication is a crucial process in the manufacturing of various electrochemical devices, including batteries, super capacitors, and sensors. The electrodes are made up of a combination of different powder materials and the electrolyte is the organic solvent with some salts dissolved. The fabrication processes vary based on the type of electrochemical device and the materials involved.
Conventionally, the electrodes are prepared by coating a slurry on metal foils. The electrodes are fabricated by creating slurry via mixing active electrode materials, conductive additives and binders with a solvent. In addition, there is a process of manufacturing electrode by dry electrode process which includes dry mixing active material, binder and conductive additives and applying the electrodes on the current collector foil by various methods which are then hot pressed. These electrodes are called dry electrodes. The dry powder mix is prepared by blending the electrode materials using a high-shear mixer. This mix is spray coated (or by other coating method) on the current collector foils and is then passed through a hot roller which melts the binder resulting in strong cohesion with other powders and adhesion with the current collector.
However, the slurry mechanism has certain drawbacks, notably the utilization of environmentally unfriendly solvents. These solvents necessitate capture and recycling, resulting in increased energy consumption during the process. Similarly, in the dry process, the binders consist of insulating polymers that impede current flow, leading to reduced power density in the cell. This, in turn, accelerates electrolyte degradation and shortens the cell's lifespan. Consequently, there is a need for an electrode fabrication method that effectively addresses these challenges.
The wet-slurry-based coating method for electrode fabrication involves the mixing active material, polymer binder, and conductive filler in a solvent, which is then coated onto current collectors, dried. N-methylpyrrolidone (NMP) is the most commonly utilized organic solvent. Evaporation of NMP requires a significant energy investment, as electrodes must be dried for several hours at temperatures as high as 120° C to remove this solvent (Huang et al., U.S. patent application Ser. No. 13/850,346, filed Mar. 26, 2013). Because of its high cost and potential as an environmental pollutant, solvent recovery is necessary in commercial applications, adding further costs to battery fabrication (Wood et al., Journal of Power Sources 2015, 275, 234-242).
IN202121043783 discloses “Dry Electrode Manufacturing Processes for Lithium-Ion Batteries” is a current energy stockpiling needs become seriously requesting, the assembling of lithium particle batteries (LIBs) addresses a sizable space of development of the innovation. In particular, wet preparing of cathodes has developed to such an extent that it is a usually utilized mechanical method. Notwithstanding its far reaching acknowledgment, wet handling of anodes faces various issues, including costly and perilous dissolvable recuperation, remove squander, covering irregularities, and microstructural surrenders because of the dissolvable drying measure. But with the dry electrode manufacturing process the binders used are polymers which obstructs the flow of current hence increasing resistance of the cell.
Therefore, due to above mentioned drawbacks, there is a requirement of an electrically conductive composite in order to minimize the resistance of a battery/cell for improving life of the battery/cell and a method of preparation thereof.

The dry electrode with binder (2) and conductive additive (1) are used in battery electrodes. The conductive additive (1) provides electrical conductivity and the binder (2) holds the active material (3) and conductive additive (1) together and adhere to substrate. However, the binder (2) has a primary property of adhesion with other compounds, providing additional stiffness, toughness and hardness to the battery electrode. Meanwhile, having a drawback of being electrically insulating, i.e., obstructing the flow of current through the electrode.
Figure 2(b) is a pictorial representation of a method (200) of preparation of electrically conductive composite (4) through wet processing according to an embodiment of the present invention. In the present invention, the active material (3) is mixed with the electrically conductive composite (4) to obtain an electrode material (5’). The electrically conductive composite (4) is prepared by carrying out following steps.

The dry electrode in conventional method (100) is composed of a combination of active material (3), conductive additive (1) and binder (2) as shown in Figure 3(a). However, the binder (2) for battery electrodes has a primary property of adhesion with other compounds, providing additional stiffness, toughness and hardness to the battery electrode. Meanwhile, having a drawback of being electrically insulated, i.e., obstructs the flow of current through the electrode.
In other words, the conventional method (100) of preparing electrode material (5) results in irregular distribution of binder (2) which causes interruption in current flow, higher resistance due to blocked conductive pathways.
Figure 3(b) is magnified view of electrode material (5’) with composite prepared via the present invention according to an embodiment of the present invention.

In other words, as depicted in Figure 4(a), the binder obstructs the conducting network. The binder (2) used in the conventional electrode material (5) achieved by the conventional method (100) creates gaps or interruptions between the conductive particles which limit the current flow. Also, the irregular distribution negatively impacts the conductivity of material an overall efficiency.
Figure 4(b) is a pictorial representation of continuous conducting network (6) that is unhindered percolation network due to composite according to an embodiment of the present invention that provides the continuous conducting network (6) with more homogeneous binder (2) distribution as electrically conductive composite (4) is replaced with conductive additive (1) and binder (2). The use of electrically conductive composite (4) as a single component, allows an unhindered conductive percolation network (i.e. continuous conducting network (6)) unlike the one formed when the binders (2) and conductive additives (1) are added separately, where the binders (2) hinder and break the conductive percolation network.
In other words, as depicted in Figure 4(b), the addition of electrically conductive composite (4) provides a more homogeneous distribution in comparison with the conventional method (100). Also, the continuous conducting network (6) is established due to an even spread of the electrically conductive composite (4) which reduces interruption in the conductive pathways, thereby allowing for smoother current flow. Additionally, the homogeneous distribution increases the electrical conductivity and performance of the material.
Figure 5(a) is a pictorial representation of a conventional non-aligned conductive pathway. The binder (2) in the conventional method (100) acts as an obstacle to continuous flow of current. In other words, as depicted in Figure 5(a), the binder particles which are non-conductive in nature act as obstacles to the flow of current when they are improperly places. Also the conductive additive (1) requires to form the continuous network for optimal performance. Also, the disruption by the binder (2) increases electrical resistance.
Figure 5(b) is a pictorial representation of an aligned conductive pathway of carbons in composite according to an embodiment of the present invention. The carbon-based conductive additives are preferably anisotropic grades of carbon (7). The combination of a selection of anisotropic grades of carbon allows long, aligned conductive pathways, thus further reducing the resistance of the electrode and also improve the mechanical binding properties of the electrically conductive composite (4), hence the strength of electrodes. In addition, the anisotropic nature of the electrically conductive composite (4) allows for better uniformity in mixing of binder (2) and thus more homogeneous binding ability.
In other words, as depicted in Figure 5(b), through the present invention, a more evenly distributed structure is achieved. The addition of the electrically conductive composite (4) ensures the formation of the continuous conducting network (6) with minimal obstruction and also ensures mechanical stability while maintaining electrode continuity. Hence, the present invention increase the efficiency and current flow in the electrode material (5’).
