Tofu-Brine Water Battery Aims 120k Cycles, Outlasting Lithium-Ion by Decades
Researchers report a tofu-brine, water-based battery with organic electrodes and neutral electrolytes achieving 120,000+ cycles and non-flammability; if scalable, it could offer a cheaper, safer alternative for grid storage and backup power, potentially challenging lithium-ion, though energy density and real-world deployment remain to be proven.
