Top 10 cell can manufacturers in China
Benefiting from the continued prosperity of the new energy industry and the rapid rise of the global energy storage market, it is expected that the global demand for power and energy storage batteries will reach 2.0 TWh by 2025, with a compound annual growth rate (CAGR) of 42% from 2022 to 2025.
On the production side, battery structural components have precision manufacturing attributes, specifically including the production of the battery cell top cover and can. This article will briefly introduce battery cell can and the top 10 cell can manufacturers in China.
Introduction to the battery cell can
The battery cell can, as a crucial component of the battery system, plays a vital role in securing the internal electrochemical system and ensuring a complete seal. The cell, which is composed of the anode, cathode, battery separator, and electrolyte, is housed inside the can.
During charging and discharging, the battery produces a certain amount of gas, leading to internal gas pressure within the can. Simultaneously, the cell undergoes expansion, with the expansion force primarily acting on the can’s inner walls that are in contact with the cell.
The structure’s strength must be sufficient to withstand this expansion without breaking. Moreover, the can exerts a counteracting force on the cell, helping to secure it in place. Crucially, this counteracting force also affects the electrochemical reactions occurring within the battery.
