In 1859, the first rechargeable battery, lead acid battery, was invented and are still widely applied in different fields. And in 1868, Zn/MnO2. in 1900, Fe/Ni battery. Ni/MH battery came into being in late 1980. It is featured by high engery ratio, 1.5 times higher than Cd/Ni battery while same voltage as Cd/Ni battery and no pollution. And it took place of Cd/Ni battery in many fields rapidly. In 1990, Ni/MH firstly fulfilled industrialization in Japan, mainly applied in electric instruments and communication equipments, etc. From 1990s, CHUNLAN started the
|
| project of power Ni/MH, in hope to substitute lead acid battery in electric vehicle field. Nowadays, many countries are engaged in the research of high capacity power Ni/MH battery. All the industrialized electric automobiles are using Ni/MH. |
