What is the potential of gas detection for early battery failure
The experiments show that battery failure detection with gas sensors is possible but depends highly on the failure case. The chosen gas sensor can detect H 2 produced by unwanted electrolysis and electrolyte vapor and gases produced by degassing of state-of-the-art LIBs. Detecting them at threshold levels could trigger an alarm or automatic shutdown. Back in 2020, a team of researchers at FM started experimenting with lithium-ion batteries in the safe confines of a lab in ways that you couldn't do anywhere else. As conventional battery management systems (BMS) often fail to provide timely warnings, gas sensing presents a more sensitive detection method.
