Water-based battery that can handle 120,000 charge cycles raises prospects of replacing lithium-ion
A Chinese research team has developed a neutral-electrolyte aqueous battery with a lifespan said to be 10 times longer than existing products. The battery could withstand about 120,000 charge-discharge cycles, suggesting it could last about 300 years in grid storage if operated at the average 2024 rate of 1.1 cycles per day. The design combines a near-neutral magnesium- and calcium-salt electrolyte with a covalent organic polymer anode to reduce degradation and environmental concerns.
