Tofu Brine Powers Revolutionary Eco Battery

Quick Smiles:

• New battery endures 120,000 cycles using safe tofu-making salts.
• Water-based design eliminates fire risks and hazardous waste.
• Abundant magnesium and calcium ensure eco-friendly disposal anywhere.

Scientists at City University of Hong Kong have developed a groundbreaking water-based battery using magnesium chloride or calcium chloride electrolytes, the same brines that coagulate soy milk into tofu.

This neutral pH, nontoxic design advances safer energy storage amid China’s booming electric vehicle and renewable sectors.

Unlike flammable lithium-ion batteries, these aqueous versions pose no explosion risks and simplify disposal.

“Compared with current aqueous battery systems … our system delivers exceptional long-term cycling stability and environmental friendliness under neutral conditions,” the team shared.

“As magnesium and calcium are naturally abundant in soil, their presence poses minimal environmental risk,” they added.

“Our findings represent a considerable advancement in the development of neutral electrolyte-compatible negative electrode materials, offering a safer, high-performance, long-lasting and environmentally sustainable energy storage solution.”
