To reduce the internal resistance of battery cells or electrolyte leakage, stacked type battery packs are typically assembled and are tightly compressed by fixture structures such as
by gaskets if the stack fixture structure is not robust. Therefore, the compression uniformity of the fixture structure becomes critically important in large scale flow type cells such as RFBs and fuel cells. This study aims to predict the bending behavior of fixture structures of large-scale battery stacks by taking a computa-tional approach.
Compared with other power batteries, lithium-ion batteries are advantageous in addressing the requirements raised by battery electric vehicles, such as, long mileage, high-current charging, and safety. Therefore, lithium batteries are reliable and feasible for the deployment in battery electric vehicles. KW - Carbon. KW - Energy system design
