About Us

SolidEnergy Systems is a Li-Metal Battery technology company. We manufacture the world?s lightest rechargeable cells at pilot scale for prototype demonstration and specialized aerospace markets. But our real future lies in the materials we supply?anodes and electrolyte?for mainstream markets such as consumer electronics and electric vehicles. We supply these to large Li-ion cell manufacturers to be integrated with a separator and cathode into full cells which can be customized for different applications including drones, consumer electronics and electric vehicles.

Because our anode and electrolyte materials are compatible with existing Li-ion cell manufacturing processes, we can achieve scalability by using existing infrastructure. This eliminates the need for costly infrastructure investment. It?s all part of our open ecosystem. It means a more seamless end-user experience, faster prototyping and no limits to growth.
