Introduction
Liquid-cooled battery energy storage systems provide better protection against thermal runaway than air-cooled systems. “If you have a thermal runaway of a cell, you've got this massive heat sink for the energy be sucked away into. The liquid is an extra layer of protection,” Bradshaw says.
As electric vehicles (EVs) are gradually becoming the mainstream in the transportation sector, the number of lithium-ion batteries (LIBs) retired from EVs grows continuously. Repurposing retired EV LIBs into energy storage systems (ESS) for electricity grid is an effective way to utilize them.
With the lithium-ion storage systems that dominate the market today, the primary safety concern is thermal runaway. At a basic level, this occurs when a failure leads to overheating inside a battery cell. This can result in the generation of a lot of heat and a self-accelerating reaction that can lead to fires or explosions.
