摘　　要：针对锂储备电池在大功率输出时激活慢的问题,提出了采用混合电解液和孔径适中碳电极提高锂储备电池激活速度的方法。该电池采用含有LiAlCl 4和AlCl 3两种电解质的混合电解液以及孔径适中的碳电极,在保持功率水平不变的前提下,以牺牲部分富余容量为代价,加快电池的激活速度。对比试验表明,使用新型电极材料后,同等放电条件下电池功率水平不变,而激活速度显著提高。当电池以3.6 W的功率放电时,电压上升到18 V的时间由原来的1.52 s缩短到90 ms,激活时间缩短到原来的6%左右。Reserve lithium battery has a long risetime when it is discharged at high power.Mixed electrolyte and middlesize-hole carbon electrode could decrease it.LiAlCl4 and AlCl3 are both used in the electrolyte and middlesize-carbon electrode is used in this battery.This new mathod could decrease rise time while losing some unnecessary capability and keeping the same power.Parallel tests were done.It is proved that risetime of the battery with new electrode is decreased obviously.Risetime to 18V is 90ms instead of 1.52s when the discharge power is 3.6W,Risetime is decreased to 6 percent of primary battery.
