Recently, Tang Yongbing, a researcher of the Functional Thin Film Materials Research Center of the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, and Cheng Huiming, an academician of the Chinese Academy of Sciences at Tsinghua-Berkeley Shenzhen University, and Ji Xiulei, a professor at Oregon State University, and their team members Zhou Xiaolong, Liu Qirong, and Jiang Chunlei, etc. "Angewandte Chemie International Edition" published a review of new dual-ion batteries, comprehensively commenting on the latest progress and development strategies of high-efficiency and low-cost dual-ion batteries (Beyond Conventional Batteries: Strategies towards Low-Cost Dual-Ion Batteries with High Performance , Angew. Chem. Int. Ed. 2019, DOI: 10.1002 / anie. 201814294). The dual ion battery has the advantages of high working voltage, low cost, environmental protection and easy recycling, and has been widely concerned at home and abroad. However, due to the limitation of graphite's compact density and theoretical capacity, the energy density of traditional dual-carbon dual-ion batteries is low. Therefore, the team of Tang Yongbing proposed a design idea of ​​an integrated electrode, using cheap, environmentally friendly and abundant reserves of aluminum foil as negative electrode active materials and current collectors, and graphite cathode materials to build a new high-efficiency low-cost aluminum-graphite dual ion battery system (Adv. Energy Mater., 2016, 6, 1502588; PCT / 2015/09996). The battery system uses cheap and environmentally friendly aluminum foil and graphite as the negative electrode and positive electrode materials respectively, eliminating the traditional positive electrode materials such as lithium cobalt oxide, the battery is more environmentally friendly and easy to recycle, and greatly reduces the cost, significantly improving the energy density of the dual ion battery . In addition, the team successfully expanded the integrated electrode design ideas to a new lithium battery system (Adv. Mater. 2016, 29, 1604219; PCT / CN2016 / 081346, PCT / CN2016 / 081344, PCT / CN2016 / 081345; Adv. Mater., 2019, 31, 1900826), which significantly increased the energy density of traditional lithium batteries and significantly reduced manufacturing costs. In order to improve the stability of the aluminum negative electrode in the new battery, the team subsequently adjusted its structure and interface, and developed three-dimensional porous aluminum / carbon negative electrodes (Adv. Mater., 2016, 28, 9979, PCT / CN2016 / 081344 ; PCT / CN2016 / 081345), aluminum anode with hollow interface structure (Adv. Mater., 2017, 29, 1606805.), carbon-coated nano aluminum anode (Adv. Energy Mater., 2017, 7, 1701967), Active material / current collector / separator multifunctional electrode (Adv. Funct. Mater., 2017, 1703035; PCT / CN2017 / 078204), ultra-fast charge-discharge integrated flexible battery (Adv. Energy Mater., 2017, 7 , 1700913; PCT / CN2017 / 078205) and multi-ion battery system (Angew. Chem. Int. Ed., 2018, 57, 16370). The team also expanded the new idea of ​​integrated design to an alkaline (earth) metal ion battery system with rich reserves, and successfully developed an environmentally friendly sodium-based dual ion battery (Adv. Energy Mater., 2017, 7, 1601963; PCT / CN2015 / 099967, Small, 2018, 14, 1703951; Adv. Funct. Mater., 2019, 29, 1806722), potassium-based dual ion battery (Adv. Mater., 2017 , 29, 1700519; Adv. Energy Mater., 2017, 7, 1700920, PCT / CN2017 / 074632; J. Mater. Chem. A, 2018, 6, 17889), and a new room temperature high voltage calcium ion battery (Adv. Sci ., 2018, 1701082; Nat. Chem. 2018,10, 667; CN201710184368.1, PCT / CN2017 / 078203; Adv. Energy Mater., 2019, 9,1803865, CN201711440242.2). Based on the above technology, the team has applied for 89 invention patents, 23 PCT patents, 2 US patents, 2 EU patents, 2 Japanese patents, 2 Korean patents, and successfully completed the technology transfer incubation.
