Solid-state batteries also perform better in stressful environments, as they are less prone to overheating, fire and loss of charge over time, however they typically cannot discharge energy at the same rate as li-ion batteries.

Until now, this has made them unsuitable for powering large electronics, such as electric vehicles, as they require batteries capable of discharging their energy an incredibly fast rate.

This issue was solved by researchers at Nasa’s Solid-state Architecture Batteries for Enhanced Rechargeability and Safety (SABERS) unit, who were able to increase the battery’s discharge rate by a factor of 10 using innovative new materials that have yet to be used in batteries.
