现在买手机,你不会再听到销售员唠唠叨叨地说“前三次充电一定要充满10个小时,一定要等到电量全部用完再开始新一轮的充电”了。为什么?因为以前的手机采用的是传统的镍氢镍镉电池,这种电池具有记忆效应需要前几次对电池完全充放电来激活,而现在的手机配备的是不存在记忆效应的锂电池。这小小的锂电池就是我现在的研究领域,而我,则是一名材料学在读博士生。什么是材料学?材料学就是研究材料组成、结构、工艺、性质和使用性能之间相互关系的学科,说白了就是研究材料的。哪些能算作材料?
Now buy a mobile phone, you will no longer hear the salesman nagging said “The first three charges must be full 10 hours, be sure to wait until the battery is fully used before starting a new round of charging ”. Why? Because the previous phone uses a traditional nickel-metal hydride-nickel-cadmium battery, this battery has a memory effect requires a few full charge and discharge to activate the battery, and now the phone is equipped with lithium-ion battery does not exist memory effect. This little lithium battery is my current research area, and I, is a doctoral student studying materials. What is material science? Material science is to study the composition of materials, structure, technology, nature and performance of the interrelationship between disciplines, to put it plainly is the study of materials. What can be counted as material?
