Brief Description for Prismatic Lithium-ion Batteries with Aluminum Shell
Prismatic aluminum shell batteries are lithium-ion batteries that use an aluminum alloy casing, composed of components such as the cell (positive and negative electrodes, separator), electrolyte, casing, and top cap. They have the following characteristics: Structural Composition: Includes a top cap, aluminum casing, and jelly roll (rolled electrode assembly), which are sealed into an integrated…

How does temperature uniformity affect battery performance?
Temperature uniformity is critical for maintaining optimal battery performance and longevity. Uneven temperature distribution within a battery pack can lead to various issues that negatively affect its efficiency, safety, and lifespan. Here’s how temperature uniformity impacts battery performance: 1. Cell Degradation Rates Impact: Cells exposed to higher temperatures degrade faster due to accelerated chemical reactions,…
