New solid state zinc battery with superb cycle performance
Researchers in Australia have developed a new class of solid electrolytes for rechargeable aqueous zinc-iodine batteries, which has allowed for extended lifespan and high-efficiency. Symmetric cells employing this electrolyte have demonstrated excellent cycle performance, maintaining stability for approximately 5,000 hours at room temperature, while all-solid-state ZnI2 batteries exhibit over 7,000 cycles with a capacity retention exceeding 72.2%.

High-efficiency, high-energy all-solid-state sodium-air battery
Researchers in South Korea have successfully demonstrated the use of free ambient air as a fuel leveraging a sodium-based solid electrolyte to tackle the carbonate issue that has been holding back the rollout of metal-air batteries. Their sodium-air battery cell has demonstrated high efficiency, incresed energy density, and a broad voltage range.
Evaluating the profitability of vanadium flow batteries
Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours.
