摘　　要：构建以硫酸盐为电解液的单体电池放电体系,探究金属阳离子、电解液浓度、抗坏血酸浓度、温度、p H、放电时间等因素对单体电池放电效率的影响。结果表明,以0.8 mol/L的Mn SO4作为电解液,温度为80℃、p H=2.78时,抗坏血酸的浓度2 g/L,放电时间8 h左右时,消电电压降低到0.54 V,此时锂电池放电达到最佳,满足绿色高效的放电条件。To construct the sulfate as the monomer battery discharge system electrolyte ,explore the metal cation, concentration of electrolyte , concentration of ascorbic acid , temperature , pH, discharge time and other factors , the influence on the monomer battery discharge efficiency .The results showed that with 0.8 mol/L MnSO_4 as the electrolyte,temperature 80 ℃,pH =2.78,2 g/L concentrations of ascorbic acid,discharge time of 8 h or so,consumer electric voltage is reduced to 0.54 V,when the battery reaches the optimal discharge conditions ,meet the green and efficient .
