摘　　要：试验研究是将锰酸锂烧结前的混合料(主要是二氧化锰与碳酸锂的混合物)压成团块,再放到烧结炉中进行烧结,由于经压团的物料接触很紧密,其堆密度由1.06 g/cm3提高到1.39 g/cm3,提高了31%,同样体积的匣钵可多装31%的物料,即在几乎相同的电耗及工时的情况下,锰酸锂的产量可提高31%,同时,也大大改善了物料间的高温固相反应动力学条件,有利于反应产物晶粒的长大及晶形完善,使锰酸锂产品的质量得到改善,压实密度由2.90 g/cm3左右提高到3.00 g/cm3以上,这有利于提高电池的体积能量密度。The experimental research is to press the lithium manganate mixture into clumps before sintering, then the clumps are put in the furnace for sintering. Because the bulk density of the mixture increases from 1.06 to 1.39 in thickness of the compacted matter, a sagger of the same volume can fill 31% more, that is to say, under the same power consumption and working hours with the traditional process, the production of lithium man- ganate can increase by 31%. At the same time, this method can improve the hyperthermia solid- state reaction dynamic condition, by helping the growth of reaction product grains and perfection of crustal form to improve the quality of lithium manganate products with an increase the compacted density from about 2.90 to above 3.00. The result is the volume energy density of the battery will be increased.
