This version of the battery also demonstrated resilience against extreme levels of abuse due to the slow-reacting nature of the SEI[3] When subjected to cutting, external puncture, exposure to salt water, and ballistic testing, the battery did not produce any smoke or fire and continued to operate even with severe external damages.
In addition, they are less heavy than traditional batteries and can be manufactured in different shapes, allowing for lighter gear and more efficient placement.
[6] The lower risk of danger that come with aqueous Li-ion batteries make them appealing for industries that manufacture vehicles that prioritize safety over energy density, such as airplanes and submarines.
On the other hand, continuous gas evolution of water during high voltage battery cycling or idling lowers the Coulombic efficiency (CE) and causes serious safety concerns over explosions.
In addition, issues relating to the manufacturing of the protective HFE coating would need to be resolved before the batteries can be scaled up in production for commercial use.
