Do Ya Know How to Calculate Li ion Battery Performance in Numbers?
With the increasing depletion of fossil energy and various environmental problems caused by burning fossil energy, it is urgent to develop the next generation of clean energy. Solar energy and wind energy are popular because they are environmentally friendly, but their intermittent nature also limits their application.
On the other hand, rechargeable batteries or supercapacitors, due to their high energy density, portability, relative safety, have gradually developed into the next generation of new energy in the leader.
As a kind of rechargeable batteries, lithium-ion batteries have developed rapidly in recent decades, and have been widely used in automobiles, mobile phones, electronics, industry and so on. In recent years, the main research directions of lithium-ion batteries are the development of high energy density, high voltage cathode materials, lithium-sulfur batteries (Li-S) or lithium-air batteries (Li-O2).
How can the performance of rechargeable lithium batteries be calculated?
As an ab initio algorithm, the First-Principle method is widely used in material design, material prediction, and interpretation experiments. DFT (Density Functional Theory), only a few classical parameters, DFT can calculate most of the properties of materials. In the field of lithium and other related fields, DFT has been widely applied. Because of its accuracy, it can effectively guide the experiment and save costs.
more secret of lithium ion batteries will be shared in later articles, welcome to follow and discuss. thank you.
