钠离子电池(Sodium-ion battery),是一种二次电池(充电电池),主要依靠钠离子在正极和负极之间移动来工作,与锂离子电池工作原理相似。 2018年12月,南京理工大学夏晖教授与中外团队合作,首创结构设计和调控方法,在锰基正极材料研究方面取得重要进展。
通过不断把带正电荷的钾离子和钠离子压出电池,电池内负电荷数量就会增加。
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.
新型电池的原理和锂离子电池的原理相同,都是通通过在充电电极和放电电极之间移动钠离子或钾离子进行能量的存储和利用。相比较之下,这种电池是非常便宜的。
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.
So, for example, in an electrochemical cell, it would be possible to take the sodium ion, give back its electron, and convert it into a metallic sodium, take the chloride ion, remove its electron, and restore chlorine gas.
所以,例如一个电化学的电池,它可能带有钠离子,让它得到电子,把它变成金属钠,得到氯离子,让它失去电子,作为氯气储存。
