Factorial Energy and POSCO FUTURE M are collaborating to develop all-solid-state batteries, which promise improvements in driving range, charging times, and safety. This partnership aims to overcome challenges in manufacturing and material selection for these next-gen batteries.

US-based Factorial Energy and South Korea’s POSCO FUTURE M are teaming up on all-solid-state batteries, the “holy grail” of battery tech.

Factorial and POSCO take on all-solid-state EV batteries

All-solid-state batteries promise significant improvements in driving range, charging times, and safety. Although next-gen battery tech shows promise in the lab, proving it in the real world hasn’t been easy.

For one, new equipment is needed to manufacture them. All-solid-state batteries also use a solid electrolyte, unlike the liquid electrolyte used in current lithium-ion batteries.

One of the biggest challenges in bringing the new battery tech to market has been finding a solid material that doesn’t crack yet still conducts electricity.
