摘　　要：报道了锂盐在铝电解中的作用。阐述了其提高熔体的电导率,降低电解质的熔点,减少铝的溶解损失,减小极化电压,降低电解质的蒸气压及延长阴极寿命等优点。提出锂盐与其它添加剂的有机结合,可获得更大经济效益和社会效益的构想。The effects of additive lithium salts on aluminum electrolysis are reported. The main advantages of additive lithium salts to aluminum electrolysis are that increasing electrical conductivity of melts, decreasing the melting point of electrolyte, decreasing aluminum dissolved in cryolite melts, decreasing polarixation voltage, depressing vapour pressures of electrolyte and prolonging life of cathode. One assumption is put forward that emormous economic and environmental benefits will he acquired when lithium salts and other additives are appropriately added to the electrolysis cell.
