电池是各种便携电子装置的发动机.八十年代以来,电池的产量不断增加,质量不断改进,产品不断更新,应用领域不断扩大.目前世界电池销售额已达260亿美元,其中小型电池市场2000年以前可望以每年6%的速度发展.以世界电池生产重镇日本为例,在各类电池中一次电池的产值占35%,二次电池占65%;而从数量说则正好相反,一次电地占83%,二次电池占17%.在一次电池中,锌锰干电池独占44%,碱锰电池其次,占17%,锌汞电池占11%.
Batteries are the engines of various portable electronic devices. Since the 1980s, the output of batteries has continuously increased, the quality has been continuously improved, the products have been continuously updated, and the fields of application have been continuously expanding. At present, the world’s battery sales have reached 26 billion US dollars, of which the small battery market 2000. Before the year is expected to develop at a rate of 6% per year. Take Japan, the world’s battery production center, as an example. The output value of primary batteries accounts for 35% and secondary batteries account for 65% in all types of batteries; Electrical land accounts for 83%, and secondary batteries account for 17%. In primary batteries, zinc-manganese dry-cell batteries alone accounted for 44%, alkaline-manganese batteries accounted for 17%, and zinc-mercury batteries accounted for 11%.
