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

Iron flow batteries with 25 year life and 4 to 10 hour duration

Iron flow batteries provide a long duration energy storage solution suited Australia's resource availability and harsh climate. ESS technology uses the abundant low-cost elements of iron, salt, and water to deliver environmentally safe battery solutions capable of providing up to 12 hours of flexible utility-scale energy storage. From sundown to sunup! “ESS iron flow technology provides cost-effective long-duration energy storage and is ideal for applications that require from 4–12 hours of flexible energy capacity. ESS systems provide resilient, sustainable energy storage well-suited for multiple use cases including utility-scale renewable energy installations, remote solar + storage microgrids, grid load-shifting and peak shaving, and other ancillary grid services. ESS technology is safe, non-toxic and has a 25-year lifespan without capacity fade. Demand for long-duration energy storage systems is expected to grow rapidly in Australia; New South Wales announced the procurement of 2 GW of LDES in its recent Electricity Infrastructure Roadmap.” Stuart Parry, Managing Director of ESI, says: “Safe and non-toxic ESS iron flow batteries are perfect in Australia’s harsh environment and the ability to locally source electrolyte provides insurance against supply chain risks and price escalation. The transition to clean energy requires new long-duration storage solutions and we look forward to working with ESS to meet the needs of an increasingly renewable energy grid.” read the whole story here; https://cleantechnica.com/2022/10/27/iron-flow-batteries-to-be-built-in-queensland/
