Lithium-Silicon Alloy
鋰硅合金其主相為Li13Si4，外觀為深灰色金屬固體粉末，性質極不穩定，遇水強烈反應產生大量熱并且放出氫氣，在潮濕空氣中會自燃。鋰硅合金作為熱電池負極材料，因其安全性、穩定性及成本低等優點，是目前用量最大的熱電池負極材料。用鋰硅合金作負極材料的熱電池，較鈣系、鎂系熱電池體系有著大功率放電、高比能量、激活迅速、貯存期長及結構緊湊等優點，特別適合大電流脈沖放電。
The main phase of lithium silicon alloy is Li13Si4, lithium silicon alloy is dark gray metal solid powder, and its property is extremely unstable, it reacts strongly with water to produce large amounts of heat and hydrogen, spontaneously ignites in moist air. Due to its advantages of safety, stability and low cost, lithium silicon alloy is the most commonly used anode material of thermal battery. Compared with calcium and magnesium thermal battery system, thermal battery using lithium silicon alloy has the advantages of high power discharging, high specific energy, quick activation, long storage period and compact structure, etc.
