Salient Energy says it has completed safety testing with Underwriters Laboratories (UL) for its proprietary zinc-ion energy storage battery, an important step on the road to market.

UL is part of a science safety enterprise that organizes essential testing for products prior to commercialization.

Salient’s zinc-ion cells were the first of their kind to be tested by UL. The results showed the batteries do not experience thermal runaway, nor do they produce toxic or explosive gasses even when subjected to extreme heat, puncture or overcharging.
