Lithium-Silicon Alloy
鋰硼合金為多孔隙結(jié)構(gòu)的脆性Li7B6基體相和韌性Li填充相組成的一種復(fù)合材料，密度0.88±0.04g/cm3，外觀為銀白色金屬，極不穩(wěn)定，遇空氣易變質(zhì)，遇水反應(yīng)劇烈。鋰硼合金主要應(yīng)用于鋰系熱電池負極材料，具有高比能量、高比功率和低極化、電化學(xué)電位與純鋰相近，600℃以上仍為固態(tài)等突出優(yōu)點，是新型鋰系熱電池的極佳負極材料。與目前廣泛使用的鋰硅合金相比，鋰硼合金作為負極材料所裝配的單元電池在最高電壓和放電工作時間這兩方面具有更好的性能。
Lithium boron alloy is a kind of composite material composed of Li7B6 matrix phase with porous structure and Li toughness filling phase, with a density of 0.88±0.04g/cm3. It has a silver-white metal appearance and is extremely unstable. It is easy to deteriorate when exposed to air and react violently when exposed to water. Lithium boron alloy has advantages of high specific energy, high specific power, low polarization and high melting point, what's more, its electrochemical potential is similar with that of pure lithium, which makes the lithium boron alloy become excellent anode material for the new thermal battery. Compared with the lithium silicon alloy which is widely used in thermal battery at present, the lithium boron alloy as the anode material of thermal battery has better performances in the highest voltage and discharging time.
