Problem
Conventional lithium-ion batteries, with their liquid electrolytes, pose safety risks due to flammability and can limit energy density and efficiency. These limitations hinder the performance and adoption of electric vehicles and other portable electronic devices.
Solution
Solid Power develops all-solid-state battery technology utilizing sulfide solid electrolytes to overcome the limitations of traditional lithium-ion batteries. Their all-solid-state batteries replace the flammable liquid electrolyte with a solid electrolyte layer, enhancing safety and enabling the use of high-capacity electrodes like lithium metal and high-content silicon anodes. This design results in batteries with higher energy density, longer life, and potentially lower costs due to compatibility with existing lithium-ion manufacturing processes. Solid Power's sulfide-based solid electrolytes offer a balance of conductivity and processability, facilitating the production of defect-free cells on industry-standard equipment.
Target Audience
Solid Power targets automotive OEMs seeking safer, longer-range, and lower-cost batteries for electric vehicles, as well as manufacturers of portable electronic devices.
