Researchers are developing a proactive 'cradle-to-crisis' strategy to enhance electric vehicle battery safety and performance. This innovative approach focuses on predicting and managing thermal runaway events by studying battery materials from their inception through potential failure, aiming for more robust and reliable power sources for EVs.
NASA's annual Invention of the Year award has recognized a new internal short-circuit device developed by its researchers. This innovation is designed to help engineers better understand and mitigate battery failures, which could lead to significant safety improvements for electric vehicle batteries and beyond.
As electric vehicle battery systems advance with higher voltages and greater energy density, ensuring safety during critical fault events like short circuits or crashes becomes increasingly complex. New active and passive isolation strategies are emerging to address these challenges, crucial for preventing escalating risks within milliseconds.
Fast charging introduces significant challenges for lithium-ion battery longevity and safety, particularly the risk of lithium plating. This phenomenon occurs when lithium ions deposit as metallic lithium on the anode surface, rather than intercalating properly, leading to reduced battery life and potential safety hazards. New research explores advanced analytical techniques to detect and manage this critical issue, ensuring more robust and safer EV power sources.
