【 摘 要 】

The pressure within a lithium-ion cell changes due to various chemical reactions. When a battery undergoes an unintended short circuit, the pressure changes are drastic - and often lead to uncontrolled failure of the cells. As part of work for others with Oceanit Laboratories Inc. for the NAVY STTR, NREL built Computational Fluid Dynamic (CFD) simulations that can identify potential weak spots in the battery during such events, as well as propose designs to control violent failure of batteries.
