Mana Battery is developing an anode-free sodium-ion battery cell using a proprietary liquid electrolyte designed to improve energy density, stability and safety. The technology eliminates conventional anode active material, with the sodium anode forming in place during charging.
According to the company, its cell architecture can deliver energy density exceeding that of lithium iron phosphate (LFP) batteries while reducing costs by eliminating anode active material. Sodium-ion chemistry also offers an alternative to lithium-based batteries using more abundant materials.
Mana Battery’s proprietary liquid electrolyte is central to the cell design, enabling the formation and operation of the sodium anode. The company is also supplying its electrolyte as a standalone product to battery manufacturers developing conventional sodium-ion cells with hard carbon anodes.
The technology is being developed for several applications, including electric vehicles and energy storage systems. Mana Battery recently signed a joint development agreement with an unnamed global EV and energy storage system manufacturer, following an August 2026 agreement with Saft, a subsidiary of TotalEnergies, to develop and commercialize anode-free sodium-ion cells.
The company is currently supplying battery cells and electrolyte samples to commercial partners and is involved in 14 customer projects, including material transfer and cell testing agreements.
Mana Battery’s anode-free sodium-ion cell and electrolyte technology also received the Battery Innovation of the Year award at The Battery Show North America 2026 in Detroit this October.
