锂电池取得突破 手机续航有救了

On the part of speaking, lithium battery comprises a cathode, anode, separator, electrolyte etc., the key performance indicators (such as rate performance and cycle life) is determined by the electrochemical properties of cathode materials, which is recognized as LiFePO4 cathode materials.
According to the Institute of metal reports, the Shenyang National Laboratory of Materials Science (joint) high performance ceramic materials research department of King Xiao Hui Research Group on the basis of former research, through the acid synthesis environment to create the extreme shortage of water, for the first time in the world to prepare 12NM [100] oriented LiFePO4 ultrathin nanosheets thick.
The significance of the nano electrode is the smallest voltage gap so far, which improves the proportion of activated particles.
And we know that the electrode is composed of a large number of particles, and its electrochemical performance is mainly dependent on the proportion of the total number of particles in the process of charge and discharge.
Chinese Academy of Sciences, said the electrode has excellent rate performance and cycle life, in 10C (60 minutes /10=6 minutes) charge and discharge rate, the cycle can be maintained after the initial capacity of 1000 times the amount of 90%. Under the 20C charge discharge rate, the capacity can still reach 72% of the theoretical capacity.
It is widely believed that this research provides a new perspective and method for improving the capacity of lithium battery, life and improving the life of electronic equipment.
