However, there are numerous chemical, electrochemical and physical processes that occur during operation of the battery that can lead to incomplete charge/mass transfer. This invariably results in degradation and eventual failure – a process that happens more rapidly if the battery is subjected to repeated fast charging.
The improvements come from learning and more mature technologies, including active liquid battery cooling, new strategies of thermal battery management as well as new battery chemistries. We could probably add many more things, as virtually everything become more advanced with very strict quality control.
Other guidance covers development of utility expertise on battery safety and completion of a comprehensive safety evaluation at each storage system facility. Another important leading practice is for utilities to identify a safety lead at each battery site.
EPRI’s battery energy storage system database has tracked over 50 utility-scale battery failures, most of which occurred in the last four years. One fire resulted in life-threatening injuries to first responders. These incidents represent a 1 to 2 percent failure rate across the 12.5 GWh of lithium-ion battery energy storage worldwide.
This article aims to answer some common questions of public concern regarding battery safety issues in an easy-to-understand context. The issues addressed include (1) electric vehicle accidents, (2) lithium-ion battery safety, (3) existing safety technology, and (4) solid-state batteries.
A common method is to install a current interrupt device (CID) inside the cell. When a cell fails, the CID will cut off the circuit. 31 A bypass device is also useful for abuse events. The bypass device discharges a battery cell to a lower charge state before it reaches thermal runaway. These are also useful for preventing overcharging.
Another thing to ponder is if a 0.1% failure rate (or one EV per 1,000) in 2023 is acceptable or if the EV industry should aim for an even lower level by 2030.
