美国于五十年代初期建立了生产电解二氧化锰(简写为EMD)的工厂,Wecco工厂(现属Kerr McGee公司)当时日产10吨。由于美军侵略朝鲜,日本接受美国大量高性能电池的订货,也开始生产EMD。1963年日本EMD年产1万吨,1970年达4万吨,占当时世界总产量的75％。从1978～1980年,世界上生产EMD的主要国家及工厂的产量年增长率为10％强。
The United States established a factory for the production of electrolytic manganese dioxide (EMD) in the early 1950s and the Wecco plant (now Kerr McGee) was producing 10 tonnes at that time. As the U.S. troops invaded North Korea, Japan accepted orders for a large number of high-performance batteries in the United States and started to produce EMDs. In 1963, the annual output of EMD in Japan was 10,000 tons, up to 40,000 tons in 1970, accounting for 75% of the total output of the world at that time. From 1978 to 1980, the world’s major countries and factories producing EMD had an annual growth rate of 10%.
