This battery is even worse than silicon-carbon batteries found in Xiaomi phones; those at least have over 900wh/l and probably very high wh/kg as well.

shawman123, 06 Feb 2026I dont think 301wh/kg is that revolutionary. Semi Solid battery that Nio used back in 2022 had... moreSemi SSB nio used was 150Kwh.40kwh Semi SSB MG4 is 180wh/kg 2026. So 301 wh/kg is quiet revolutionary considering its first gen and 1000 wh/kg has already been demonstrated and LFP cant go that high

I dont think 301wh/kg is that revolutionary. Semi Solid battery that Nio used back in 2022 had 360wh/kg. Qilin has 255 wh/kg density as well. Plus modern batteries have gone well above 5C(even 12C). So SSB has to have something special to stand out.

This battery has 4C charging. VW doesn't have EV arch that supports 4C. VW better speed up their 800V arch plans
