IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates. This chemical sequence stores and releases energy on demand. —co-author Rachid Amine More electrons stored means higher energy density. The TEM images provided valuable insight into the four-electron discharge mechanism.

Old empires could be the key to a new car future – ET Auto

Baua Electric

The most promising path to exploiting hydrogen is to store the gas in a tank, as you would gasoline, then feed it into a fuel cell where it combines with oxygen to create an electric current, with water as a byproduct. What companies like Hyundai are also attempting to do is create the infrastructure to extract, store and transport hydrogen.

How Much Does it Cost to Charge an Electric Car at a Public Charging Station?

EV Connect

We can’t expect the market to move en masse towards electric until the public recharging network matches the landscape for petrol-powered vehicles. Today’s gas station is no longer just a row of pumps, but has typically expanded to a grocery store, coffee stop, ATM and car wash. It’s where 80% of Tesla drivers refuel, for example.
