24M says its new separator tech eliminates dendrites in Li-ion batteries

Battery manufacturing technology provider 24M has unveiled a new battery separator tech called 24M Impervio, which the company says can make EV batteries substantially safer by inhibiting the growth of dendrites (rootlike metal growths that can build up on the anode surface, potentially causing a short-circuit that can lead to a fire). 24M’s Impervio technology… Read more »

24M’s Electrode-to-Pack tech does away with cells and modules

Since the advent of modern EVs, the mantra has been “cell/module/pack.” More recently, some battery makers have started removing modules from the equation with cell-to-pack architectures. Now Massachusetts-based battery developer 24M Technologies wants to eliminate the whole hierarchy. The company calls its Electrode-to-Pack system, which it introduced at the recent Japan Mobility Show, “a streamlined… Read more »

24M receives $3.8 million from USABC for fast charger development
