[0003] The widespread adoption of lithium-ion batteries (LIBs) in a myriad of applications, from smartphones to electric vehicles, has undoubtedly transformed the way we live and work. These energy-dense power sources have revolutionized industries, providing portable and efficient energy storage solutions. However, with the proliferation of LIBs comes a pressing challenge: how to manage their environmental impact throughout their lifecycle.
[0004] Prismatic battery cells are known for their rectangular or parallelepiped shape, which makes them suitable for compact and efficient energy storage. However, like all batteries, prismatic cells need to be discharged for various reasons, such as maintenance, recycling, or testing. Efficient and controlled discharging of prismatic battery cells is essential to ensure safety, recover valuable materials, and manage the battery's end-of-life.
[0005] At the core of addressing the environmental challenges lies the crucial concept of battery recycling. Recycling is becoming increasingly important in the context of sustainability and resource conservation. Discharging a battery before recycling prevents fire & explosion and helps recover valuable materials like lithium, cobalt, and nickel, which can be reused in the production of new batteries. Efficient discharging systems can contribute to reducing the environmental impact of battery production and disposal.
[0006] There is, therefore, a need to overcome the above drawback, limitations, and shortcomings associated with the existing techniques, and provide an efficient solution for fast discharging of battery cells through conducting members and an insulated tank filled with fluid and maximize the utilization of heat generated during the discharging process.
