电池技术的变化一直很慢,不像其它快速变化的技术那样给人冒险刺激的感觉。1800年,Alessandro Volta伯爵发明了第一个电池。一直到200年之后才出现了下一个重大突破:镍铬(NiCd)电池。而自 NiCd 电池出现至今,又过去了40多年。但是最近,两股重要力量已经加速了电池技术的变化,并将电池技术推到了最前沿。首先,对环境的担忧要求取代 NiCd 电池中有毒的铬的作用。其次,消费者对电池驱动的便携式产品需求出现了飞 Battery technology has been slow to change, not as exciting as any other rapidly changing technology. In 1800, Count Alessandro Volta invented the first battery. Until 200 years after the next major breakthrough: NiCd batteries. Since the advent of NiCd batteries, it has passed 40 years. But recently, two major forces have accelerated the battery technology changes, and battery technology to the forefront. First, environmental concerns call for replacing the toxic chromium in NiCd batteries. Second, consumer demand for battery-powered portable products appears to fly
