(Phys.org) —Phinergy, an Israeli developer of metal-air energy systems, has demonstrated a new type of aluminum-air battery that is capable of providing enough energy to power an electric vehicle (EV) for up to 1000 miles ...
(Phys.org)—Scientists with a common goal, to figure out an alternative to the lithium ion battery, the main power source of choice, are not giving up. The quarrel is not with the lithium ion battery's performance but in ...
(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
(Phys.org) -- Lithium ion batteries drive devices from electric cars to smartphones. And society is demanding more batteries with more capacity from each battery.
