Compared to the screen, the processor performance technology, the rapid development of flash memory chips, lithium battery life is still the "Achilles heel" of electronic devices. In terms of the composition, the lithium battery consists of positive electrode, negative electrode, separator, electrolyte, etc. The key performance indicators (such as rate performance and cycle life) are determined by the electrochemical performance of the positive electrode material. LiFePO4 is the recognized positive electrode material. According to the Chinese Academy of Sciences reported by the metal, the Shenyang Institute of Materials Science (Joint) Laboratory of High Performance Ceramic Materials Wang Xiaohui research group based on previous studies, by creating extremely acidic water environment synthesis, the first time in the world to prepare a 12nm thick [100] oriented LiFePO4 thin nanosheets. The significance of the nanosheet electrode is that it is by far the smallest voltage gap, increasing the number of activated particles. However, we know that the electrode consists of a large number of particles whose electrochemical performance depends mainly on the proportion of particles (activated particles) that participate in the electrochemical reaction during the charge-discharge process in the total number of particles. The Chinese Academy of Sciences said the electrode has excellent rate performance and cycle life, at 10C (60 minutes / 10 = 6 minutes) charge and discharge rate, after 1000 cycles to maintain the initial capacity of 90%. At 20C charge and discharge rate, the capacity can still reach 72% of the theoretical capacity. The outside world is generally believed that this study provides a new perspective and methods to improve lithium battery capacity, life expectancy and thus improve the life of electronic devices.
