As our ESS may operate in harsh environments with extremes of temperature and frequent charge/discharge cycles,
it is important to have "Safety-In-Design" to prevent the risk of accidents.
INCELL has a number of unique safety technologies that can prevent an initial fire
and reduce the risk of it spreading from the cell to other parts of the ESS.
