Battery with 120.000 cycle life, low powerdensity but cheap, green!

Made with tofu water, no mention of cathode or andode chemistry... For reference, batteries in things like cellphones typically require around 800 cycles before the battery starts to degrade. EV batteries typically last between 1,500 and 3,000 cycles, and a good LFP grid battery lasts between 6,000 and 10,000 cycles. Can it scale? At over a hundred thousand cycles, this could mean a single water-based battery could last at least a decade or so. For applications like grid storage (solar farms, wind balancing), that’s extremely valuable. And it is this kind of application that the new battery is likely aimed at. While it could, theoretically, be used in things like phones, such batteries have lower energy densities and may not be appropriate in the long run. It is important to note that battery breakthroughs like this seem to happen all the time in academia, but not all “make it” to market. What really matters is if the tech can be scaled, is energy-dense enough to complete, and can prove cheap at an industrial scale. “Compared with current aqueous battery systems … our system delivers exceptional long-term cycling stability and environmental friendliness under neutral conditions,” the team said in a paper published in the peer-reviewed journal Nature Communications on February 18. According to the researchers from City University of Hong Kong, Yanan University, the Southern University of Science and Technology and Songshan Lake Materials Laboratory, their battery can last more than 120,000 recharge cycles with minimal performance loss. “Such performance highlights the research potential of this work and underscores its promise for practical application,” the team said. here is the link: https://www.nature.com/articles/s41467-026-69384-2
