Abstract:

The widespread use of Lithium-ion batteries in present energy storage systems faces critical challenges regarding their real-world mechanical durability, which strongly affects electric vehicles and portable electronic applications. A laboratory evaluation examines the mechanical consequences of drop and impact testing that affect lithium-ion battery cells' electrical performance variables and battery lifespan. The research utilized two methods that synchronized finite element simulations with experimental testing of drops and impacts under multiple operational conditions. Impact tests and mechanical stresses demonstrate direct relationships with electrical parameter shifts, which consist of elevated internal resistance and capacity failures coupled with unstable voltage outputs. Lithium-ion cells demonstrate extreme vulnerability to mechanical forces, presenting safety issues, durability challenges, and performance instability effects. This research delivers important findings about battery system engineering that help designers create stronger cell construction methods combined with protective encasement improvements to reach enhanced reliability and safety standards. This research makes important advancements in energy storage science by studying unexamined relationships between mechanical forces and electrical responses in lithium-ion batteries.
