多年来,实用的蓄电池一直是铅蓄电池(酸性)和镍铁蓄电池(碱性)等少数几个品种。使用广泛的铅蓄电池容量有限,一般每千克只有4～10安时,而且重量较大,价格较高,寿命不长。近年来由于科学技术的进步和能源短缺的刺激,蓄电池的研制出现了一些引入注目的发展。传统的铅蓄电池正在改进,普通的铅酸电池,电能贮存于金属极板之间,它们在酸性溶液里产生离子,工作越久,正负极板上的 PbO_2 和 Pb 就越少。据报导,法国最近发明了一种新型铅蓄电池,其极板上复盖了一层环氧树脂作为封闭极板的保护材料,其充放电次数为普通型的10倍。
Over the years, the practical battery has been a lead acid battery (acid) and nickel-iron battery (alkaline) and a few varieties. The use of a wide range of lead-acid battery capacity is limited, generally only 4 to 10 Ah per kilogram, and weight, higher prices, life expectancy is not long. In recent years, due to the progress of science and technology and the stimulation of energy shortage, there have been some remarkable developments in the development of batteries. Traditional lead-acid batteries are being improved. In ordinary lead-acid batteries, electrical energy is stored between the metal plates. They produce ions in an acidic solution. The longer the work, the less PbO 2 and Pb on the positive and negative plates. It is reported that France recently invented a new type of lead-acid batteries, the plate covered with a layer of epoxy resin as a protective material for the closed plate, the charge and discharge times of 10 times the normal type.
