Solid-state batteries show signs of life as Seeo deploys kWh-scale unit for SunEdison solar installation

The liquid electrolytes inside lithium-ion (Li-ion) batteries have long been a source of consternation. LiPF6 dissolved in a carbonate solvent is a typical electrolyte culprit: very volatile, flammable, and prone to release heat and gas when abused. High-profile Li-ion safety failures keep happening...
