金屬鋰因其具有質量輕、工作電壓高、內阻恒定、可承受大電流放電、比能量高等優點常用于鋰錳、鋰亞、鋰鐵等一次電池的負極材料。

鋰系合金（鋰硅合金、鋰硼合金）因其具有良好的耐高溫穩定性、單體電壓高、功率大、高比能量等優點，常用于熱電池的負極材料。

除了上述用途外，近年來，鋰及鋰系合金也陸續用于新型鋰的二次電池，如鋰硫電池、金屬聚合物電池、石墨烯電池及鋰超級電容器等產品。

     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.
