Scientists solve a long-standing puzzle for Na-ion battery leading to a general conceptual rule

The lithium-ion battery is a very popular energy storage device that provides power for our laptops, cellphones, hover boards, etc. However, there are serious safety problems with lithium-ion batteries, including serious fires caused by dendrite growth during charging. There are also cost issues. To overcome these problems, research has turned toward alternative batteries using other alkali metals such as sodium or alkaline-earth metals like magnesium as the active cation. Among these, sodium-io
