目前市场上最先进的电池是锂离子电池,未来的电池会是什么样的呢?它们会有什么特点和功能呢?目前在这个领域有什么发展动态呢?未来的电池,我们希望它更小、更轻,充电时间更短,充电之后放电时间更长,使用寿命更长,最好是十几年,甚至几十年.电池有多重的问题我们先来做几道简单的算术题.我们知道,50kg的汽油可以驱动一辆轻型小汽车行驶约500 km.那么50 kg汽油充分燃烧,可以释放多少热能呢?已知汽油的质量能量密度是12.7 kW·h,50 kg汽油完全燃烧所释放的能量就是635 kW·h.内燃机的效率通常在
Currently the most advanced battery on the market is a lithium-ion battery, the future of the battery will be like it? What they will have the characteristics and functions? What is the development trend in this area? The future of the battery, we hope it is smaller , Lighter, shorter charging time, longer discharge time after charging, longer life, preferably more than a dozen years, or even several decades.We have a battery of multiple problems we first do a few simple arithmetic problems.We Know that 50 kg of gasoline can drive a light car driving about 500 km. So how full of 50 kg of gasoline can be burned, how much heat can be released? The known mass energy density of gasoline is 12.7 kW · h, 50 kg of gasoline released completely combustion The energy is 635 kW · h. The internal combustion engine efficiency is usually at
