Recently, Tang Yongbing and his team of the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences developed a new type of high-performance, low-cost lithium-ion technology that is universally applicable. The research results have great industrial application prospects. Once the technology is mature, it is expected to change the existing lithium-ion battery industry structure. The related results were recently published in Advanced Materials and applied for an international invention patent. Different from the existing traditional lithium-ion battery structure, the new battery structure is: direct use of Aluminum foil at the same time as the battery cathode and current collector, replacing the traditional lithium-ion battery graphite cathode and copper foil current collector; cathode material is commercially available Positive electrode materials (lithium cobaltate, lithium iron phosphate, ternary, etc.); electrolytes are conventional carbonate solvents. The new battery has a brand-new working principle: when charged, lithium ions are de-embedded from the positive electrode material, and move to the aluminum foil negative electrode surface to form an aluminum-lithium alloy with aluminum; during discharge, lithium ions are extracted from the aluminum-lithium alloy and embedded in the positive electrode. Material. This new type of lithium battery not only can significantly reduce the battery's own weight and volume, significantly improve the quality and volume energy density, but also greatly reduces the manufacturing cost, and has a wide range of universality.
