Recently, the team of Wu Zhongshuai, a researcher of the two-dimensional material and energy device research group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Bao Xinhe, an academician of the Chinese Academy of Sciences, have developed a plane integrated Solid-state lithium-ion micro battery. Related research results were published in "Nano Energy" (Nano Energy). With the rapid development of flexible, wearable, miniaturized and integrated electronic devices, there is an urgent need to develop high-performance, lightweight, wearable and integrated structural and flexible power supplies and technologies. Lithium ion batteries are currently the most widely used and popular power supply in the society, but there are safety issues such as large size, fixed shape, poor flexibility, electrolyte leakage and flammability, so it is difficult to meet the requirements of flexible and miniaturized electronic devices demand. Recently, the research team pioneered the development of an all-solid-state planar integrated lithium-ion micro battery. The lithium-ion miniature battery uses nano-lithium titanate nanospheres as the negative electrode, lithium iron phosphate microspheres as the positive electrode, high-conductivity graphene as the non-metal current collector, and ionic gel as the electrolyte. Separator and metal current collector. The obtained lithium-ion micro-battery has the advantages of multi-directional mass transfer, showing high volume energy density of 125.5mWh / cm3, excellent rate performance; ultra-long cycle stability, the capacity is basically not decayed after 3300 cycles; and good machinery Flexible, its electrode structure is not damaged and its electrochemical performance is not significantly changed under repeated bending or twisting. At the same time, the miniature energy storage device can work stably in a high temperature environment of 100 ° C and has long cycle stability (1000 cycles). In addition, the lithium-ion battery can realize modular self-integration without metal connectors, and can effectively regulate the output voltage and capacity. Therefore, the lithium-ion micro battery has great potential in the application of flexible and miniaturized electronic devices. The above work was supported by projects such as the National Natural Science Foundation of China, the National Key R & D Program, and the National Youth Thousand Talents Program.
