Achieving unprecedented cyclability of flowless zinc-bromine battery
Researchers at the Gwangju Institute of Science and Technology in South Korea have developed a novel electrode that effectively suppresses the harmful self-discharge phenomenon in flowless zinc-bromine batteries and enables long-term operation of more than 10,000 cycles.

New cathode material for high energy density sodium-ion batteries
Researchers at Karlsruhe Institute of Technology (KIT) in Germany have successfully synthesized, for the first time, a new cathode active material with a specific capacity of 190 mAh/g, potentially paving the way to high energy density sodium-ion batterieies.

Energy-storing carbon fibre composites pave the way to weightless batteries
Building on research work at Sweden's Chalmers University of Technology, Sinonus has developed carbon fiber-based structural batteries that not only store energy but also become an integral part of a product's structure. Their possible span of energy density is said to be around 25-50% of a conventional lithium-ion battery at current technology level.

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.
