Empa, UNIGE team develop prototype solid-state sodium battery; focus on improving the solid-solid interface

Green Car Congress

Researchers at Empa and the University of Geneva (UNIGE) have developed a prototype of a novel solid-state sodium battery with the potential to store extra energy and with improved safety. The closo-borate sodium superionic conductor—Na 2 (B 12 H 12 ) 0.5 (B B 10 H 10 ) 0. —Duchêne et al. Duchêne et al. Click to enlarge.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

With the nanodots in place, the material had a four-fold higher electrical storage capacity than the original MXene and almost reached the theoretical maximum capacity of graphite. Unlike graphite, MXenes can also intercalate sodium and potassium ions, notes Alshareef. Resources Bayhan, Z., El-Demellawi, J. Alhajji, E.,

How clean is EV battery manufacturing?

Electric Auto Association

When EV batteries degrade enough to be unsuitable for cars (about 70% capacity remaining), they are re-used for electricity storage. Battery Usage Electric car batteries are generally warranted for 8 years or 100,000 miles, but new EV batteries are lasting much longer—in some cases, close to 500,000 miles.
