- 1,2比较好写。11780年的一天,意大利解剖学家伽伐尼(Luigi Galvani)在做青蛙解剖时,两手分别拿着不同的金属器械,无意中同时碰在青蛙的大腿上,青蛙腿部的肌肉立刻抽搐了一下,仿佛受到电流的刺激,而如果只用一种金属器械去触动青蛙,就无此种反应。伽伐尼认为,出现这种现象是因为动物躯体内部产生的一种电,他称之为“生物电”。1799年,伏特把一块锌板和一块银板浸在盐水里,发现连接两块金属的导线中有电流通过。于是,他就把许多锌片与银片之间垫上浸透盐水的绒布或纸片,平叠起来。用手触摸两端时,会感到强烈的电流刺激。伏特用这种方法成功制成了世界上第一个电池“伏特电堆”。这个“伏特电堆”实际上就是串联的电池组。1836年,英国的丹尼尔对“伏特电堆”进行了改良,又陆续有效果更好的“本生电池”和“格罗夫电池”等问世。然而在当时,无论哪种电池都需在两个金属板之间灌装液体,搬运很不方便,特别是蓄电池所用液体是硫酸,在挪动时很危险。干电池的鼻祖在19世纪中期诞生。1860年,法国的雷克兰士(George Leclanche)发明了碳锌电池,这种电池更容易制造,且最初潮湿水性的电解液逐渐用黏浊状类似糨糊的方式取代,于是装在容器内时,“干”性的电池出现了。1887年,英国人赫勒森(Wilhelm Hellesen)发明了最早的干电池。相对于液体电池而言,干电池的电解液为糊状,不会溢漏,便于携带,因此获得了广泛应用。
