Prompted by news of Cosmos Lab’s funding round for its non-lithium ESS battery, here’s a look at zinc-halogen aqueous battery chemistry and the patent landscape around it.
CATL has reconfirmed 2027 pilot production for all-solid-state batteries, while LFP’s cathode-material share has already expanded to 63.6%. The next-gen and current-gen races are running in parallel.
Oxide-based solid electrolytes are stable and easy to handle, but solid-solid contact creates interfacial resistance. Here’s how KR20130136150A and a 2026 Chery Automobile filing each try to solve it.
LFP took 64.3% of the awarded volume in Korea’s second ESS central-contract market. Winning the contracts is one thing; building out the material ecosystem behind them is another.
LG Energy Solution and Samsung SDI are competing for Hyundai’s Atlas humanoid robot battery contract, expected to be decided around year-end. The 21700 cylindrical format looks like the front-runner.
CATL clears a thermal-propagation test for a 350Wh/kg aviation cell, Factorial’s Solstice runs at 90°C with no cooling, and Verkor starts up its second French gigafactory line.
GL Research sees TOP Materials’ materials, electrode-foundry, and systems-engineering businesses growing together, but the more interesting story is its precursor-free cathode technology.
Large prismatic cells sometimes place several electrode assemblies in one can and connect them in parallel. We explain why, and the claim scope of CATL’s current-collecting component patent.
CATL’s Naxtra sodium-ion battery is shaking up the low-cost segment. Here’s how the patent landscape splits between layered-oxide cathodes that reuse lithium-ion tech and low-cost Prussian-blue alternatives.
After tabless electrodes cut resistance, the next round of 4680 patent competition is shifting to thermal management — WO2017043889A1’s cooling-fin design is a key example.
