The lightest metal on Earth.

Now the lightest rechargeable cell in the world.

Lithium: an element with unlimited potential that has gone unrealized, until now. Through our proprietary anode design, electrolyte formulation and cell assembly process, we’ve harnessed its power and created the first semi-solid lithium metal cell.

Cracking the Lithium Metal Code

Engineers have long attempted to capitalize on the superior energy density of lithium metal. But its high reactivity made lithium-metal cells extremely flammable and difficult to recharge. SolidEnergy’s cell solved this by using an ultra-thin lithium-metal foil for the anode, a proprietary electrolyte that is stable on lithium metal, and an innovative cell design.
