By pumping positively charged potassium and sodium ions out of the cell, the number of negatively charged ions inside the cells rises.

日本研究理事会生产的电池是圆筒状的,中心里的钠由一个允许钠离子通过而产生电流的陶制薄膜分开。
The NGK battery is a cylinder with sodium in the center, separated from molten sulfur by a ceramic membrane that allows the passage of sodium ions to create the battery's current.
It relies on the same principle employed in lithium-ion batteries-moving sodium or potassium ions between electrodes during charging and discharging-but does it much more cheaply.
