Professor Wang Qing from National University of Singapore successfully developed a new type of liquid lithium-air battery. The cell separates the formation and decomposition of lithium peroxide from the cathode of the cell by the redox molecules dissolved in the flowing electrolyte, which effectively avoids blocking and passivation of the pores of the electrode. The new battery maintains both the high energy density of lithium-air cells and the safety and flexibility of traditional flow batteries. The research was published in the Chemical Society of the Royal Society of Chemistry. Due to its high energy density (about 10 times that of lithium-ion batteries), lithium-air batteries have attracted the attention of many researchers in recent years, but poor electrode kinetics lead to very large battery polarization. Therefore, many researchers focus on the cathode material on the catalyst modification and optimization. Currently the most studied lithium-air battery catalysts include carbon-based materials, precious metal materials, transition metal oxide materials, titanium-based materials and so on. But these materials still have their inherent flaws. For example, when the surface of the catalyst material is covered by the discharge product of lithium peroxide, the catalyst loses its catalytic effect. Therefore, soluble catalysts become a solution to the above problems. Professor Wang Qing's research team uses a soluble catalyst to integrate lithium-ion batteries into the flow system. When working, the battery's discharge products are generated in a separate air diffuser to solve these problems. Making the new battery system has both high energy density, but also have good safety and flexibility. In addition to the above research and development of liquid lithium-air batteries, the research team also proposed and demonstrated liquid-flow lithium-ion batteries in recent years. The battery operates in a similar manner to conventional flow batteries, but with energy stored in lithium-ion battery materials, its energy density can reach more than 10 times that of vanadium flow batteries and is more secure than lithium-ion batteries Sex. Liquid lithium-air batteries and liquid lithium-ion batteries have good application prospects in large-scale energy storage. First, its high energy density has pushed the fluid storage system to a new limit, dramatically reducing space occupancy. Second, the battery has very good safety and can be recharged quickly, Automotive applications have obvious advantages; In addition, the battery can be modular production. These advantages make it very competitive in many areas. Therefore, liquid lithium-air batteries and liquid lithium-ion batteries will play an important role in the future energy storage market.
