原电池发展概况

Zn-MnO_2电池仍然是主要的商品电池,提高MnO_2的质量是改进Zn-MnO_2电池质量的关键之一。锂电池是近十多年中发展起来的高能电池,其中Li-MnO_2和Li-(CF_x)_n是两个比较好的系列。固体电解质电池有许多优点,可能是今后发展的一个方向。文中也谈到了银电池、热电池、空气电池。总的趋势是向着能密度高、体积小、容量大、无污染、易贮存等方向努力。

A REVIEW ON THE DEVELOPMENT OF PRIMARY BATTERIES

In the past three decades, Leclanche batteries are still predominanting in commercial battery production. An important factor in improving Zn-Mno_2 system is to raise the quality of MnO_2. Lithium cell belong to the category of high energy batteries which have been growing rapidly during the last decade, Li-MnO_2 as well as Li-(CF_x)_n systems are the safest ones in all Lithium cells.Cells with solid electrolytes are, in many respects, better than other batteries. The development of solid electrolyte cells is a new direction for primary battery production. Silver cells, thermal batteries and Zn-air batteries are discussed briefly in this paper.The general tendency of primary battery development is to achieve high energy density, compactness, non-pollution, wide operating range and long shelf life.
