New tech could lead to cheaper, more capacious batteries
New research shows that sodium rechargeable batteries could replace lithium-ion batteries in electronics and some electric vehicles, Nature reported. This would require using a new electrode material that contains iron rather than nickel and cobalt. Sodium and iron is widely available, and using them would drive costs down while creating similar energy density to electrodes in lithium batteries.
