Researchers in China have developed a water-based battery that can withstand over 120,000 charge cycles, significantly outlasting conventional lithium-ion batteries, which typically support 1,000 to 3,000 cycles. This battery utilizes organic electrodes and non-hazardous, neutral electrolytes, making it non-flammable, in contrast to lithium batteries.

While it has a lower energy density, limiting its use in electric vehicles and smartphones, it could be beneficial for renewable energy storage alongside wind farms or solar fields. If mass production is achieved, the battery could greatly influence the energy transition.
