Solidion Technology has announced that it has been granted key patents for solid-state batteries, which it believes could revolutionise the lithium battery industry. The company plans to commercialise this technology within two to three years.
Conventional lithium-ion batteries pose fire and explosion risks due to volatile and flammable organic solvents in their liquid electrolytes. The newly granted patents provide an innovative solution that readily converts certain liquid solvents into quasi-solid or solid-state electrolytes, thereby reducing or eliminating flammability. Flame-resistant electrolytes are crucial for the safe operation of energy storage systems (ESS) in smart grids, renewable energy storage, and various electric vehicles, including drones, e-bikes, electric cars, eVTOLs, and e-boats.
The technology essentially includes using any current lithium-ion cell manufacturing facility to produce dry battery cells, injecting a proprietary liquid electrolyte into the dry cells, and then converting the liquid electrolyte in situ (inside a cell) into a solid electrolyte. Solidion scientists are pioneers in this ‘in situ solidification’ or ‘liquid-to-solid conversion’ technology in the battery space.
This breakthrough allows for the immediate large-scale production of solid-state batteries using current manufacturing facilities, eliminating the need for new processes and equipment.
