金属锂因其具有质量轻、工作电压高、内阻恒定、可承受大电流放电、比能量高等优点常用于锂锰、锂亚、锂铁等一次电池的负极材料。
锂系合金(锂硅合金、锂硼合金)因其具有良好的耐高温稳定性、单体电压高、功率大、高比能量等优点,常用于热电池的负极材料。
除了上述用途外,近年来,锂及锂系合金也陆续用于新型锂的二次电池,如锂硫电池、金属聚合物电池、石墨烯电池及锂超级电容器等产品。
Because of its advantages of light weight, high working voltage, constant internal resistance, high current discharge and high specific energy, lithium metal is often used as anode material for Li/MnO2 batteries, Li/SOCl2 batteries, Li/FeS2 batteries and other primary batteries.
Lithium alloy (Li-Si alloy, Li-B alloy) is often used as negative electrode material for thermal batteries because of its good high-temperature stability, high monomer voltage, high power, high specific energy and so on.
In addition to the above applications, in recent years, lithium and lithium alloys have been used in new lithium secondary batteries, such as lithium-sulfur batteries, LMP batteries, graphene batteries and super-capacitors.
