[Abstract]:All-solid-state thin film lithium battery uses solid electrolyte instead of traditional electrolyte and adopts the planar structure of multi-layer thin film stacking. It belongs to a new generation of lithium-ion battery. It has a broad application prospect in the fields of dual-use wearable equipment, portable mobile power supply, automobile and aeronautical power battery and so on. This kind of battery has been paid more and more attention because of its high safety, long cycle life, high specific capacity and high energy density. In this paper, the classification and charge-discharge principle of thin film lithium battery are summarized, the development of positive and negative electrodes, electrolyte thin film materials and the improvement of thin film preparation methods are summarized, and the latest research progress in this direction is introduced by comparing the electrochemical performance of all kinds of battery materials: three dimensional thin film lithium battery, deformable flexible battery, high voltage and large capacity battery pack. This paper summarizes the foreign commercial battery products, key advantage technologies and battery preparation equipment, and puts forward the scientific problems to be solved urgently and the potential industrialization direction of thin film lithium battery in China.
