After decades of lithium-ion batteries dominating the market, a new option has emerged: batteries made with sodium ions.

Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in ...

Also known as sodium batteries, these devices operate on principles similar to lithium-ion batteries but use more abundant and cost-effective materials. Instead of lithium, nickel, and cobalt, they ...

Lithium-ion has proven so successful due, in part, to its very high energy density, lack of the “memory effect” (where cells become more difficult to charge over time) unlike previous battery ...

This couldn’t be more wrong for lithium-ion batteries. It’s a leftover myth from lead-acid cells, and it’s pretty undesirable to charge your modern smartphone this way. According to iFixit ...

A research team from The University of Tokyo has succeeded for the first time in directly observing the space charge layers ...
