Nickel Hydride No. 5

　　New breakthrough in Nickel Hydride No. 5 research, the problem of used batteries is expected to be solved

　　【introduction】

　　Due to the increasing demand for rechargeable lithium-ion batteries (LIBs), environmental friendliness and sustainability have become key factors for electrode materials. However, manufacturing inorganic electrode materials such as LiCoO2 and graphite consumes a lot of energy and releases large amounts of CO2. In addition, used batteries may cause more serious environmental problems by leaking toxic heavy metals in cobalt-based electrodes into soil and water. To circumvent environmental and sustainability challenges, it is of great significance to develop energy-saving, sustainable and recyclable battery materials.

　　【Achievements Introduction】

　　Recently, the team of Wang Chunsheng (corresponding author) at the University of Maryland designed a new chemical substance based on the electrochemical conversion of nitro compounds into azo compounds for high-performance lithium-ion batteries. Lithium 4-nitrobenzoate (NBALS) was selected as a model nitro compound, and the structure, lithiation/delithiation mechanism and electrochemical properties of nitro compounds were systematically studied. NBALS has an initial capacity of 153mAhg-1 at 0.5C and maintains a capacity of 131mAhg-1 after 100 cycles.
