A novel quasi-solid-state sodium metal battery
TaiSan has developed a novel polymer electrolyte and sodium metal anode that boosts battery energy density, while keeping costs low. The IP is in new material design and its process. An ideal interface is generated between electrolyte-electrodes to ensure a high cycle life and utilise existing Li-ion battery production lines to scale.
The need
Current sodium-ion batteries have too low an energy density to meet the needs of EVs. Solid-state cells are an option, but need high temperatures to operate, high stacking pressure, complex equipment to scale, and metal anodes have dendrites growth that limits cycle life.
The solution
TaiSan has developed a novel polymer electrolyte and sodium metal anode that boosts battery energy density, while keeping costs low. The IP is in new material design and its process. An ideal interface is generated between electrolyte-electrodes to ensure a high cycle life and utilise existing Li-ion battery production lines to scale.
The value proposition
- Smaller and lighter battery packs in EVs.
- Reduced costs – maximising benefits and profit margins.
- Enhanced safety, eliminating fire risk.
- Improved LCA metrics by not using lithium, nickel, cobalt and copper metals.
