The material has both active components, through which lithium ions move when the battery is charged or discharged, and inactive ones that help stabilize the active material and extend battery life.

该材料具有两种有效成分，通过它移动时的锂离子电池充电或放电，这有助于稳定活性物质，延长不活跃的电池寿命。

The core of each sphere is a crystal of lithium iron phosphate. This acts as a standard battery material.

球体的核心是一组磷酸亚铁锂晶体，这相当于标准电池材料。

A battery's electrolyte is the material through which ions (in this case lithium ions) pass from one electrode (the cathode) to another (the anode) inside a battery cell.

电池的电解质能让离子(此处为锂离子)自电池内部从一个电极(负极)传递到另一个(正极)。
