调查发现,许多消费者在选择手机电池时,存在两大误区: 一、盲目追求新技术。目前手机电池分三种类型:镍镉、镍氢和锂电池。镍镉类电池因含有汞、镉等有害重金属及“记忆效应”,现在已经基本被淘汰;镍氢电池属环保型,采用金属化氢代替了剧毒的汞、镉等材料,安全系数高,供电性能稳定,无记忆效应,技术比较成熟;锂电池虽然为新技术,具有重量轻的独特优势,但由于锂属活泼元素,化学性 The survey found that many consumers choose cell phone battery, there are two errors: First, the blind pursuit of new technologies. At present, cell phone batteries are divided into three types: nickel-cadmium, nickel-metal hydride and lithium batteries. Nickel-cadmium batteries because it contains mercury, cadmium and other harmful heavy metals and the “memory effect” has now been basically eliminated; nickel-metal hydride batteries are environmentally friendly, the use of metal hydrogen instead of highly toxic mercury, cadmium and other materials, high safety factor, Power supply performance is stable, no memory effect, the technology is more mature; although the lithium battery is a new technology, with the unique advantages of light weight, but because of lithium is an active element, chemical
