Project 973 “green secondary battery related to a new system for basic research” at the battery of high-power, high-energy, safety, recycling and design of new materials has made significant progress: in the high-power nickel-metal hydride batteries, the battery and related Materials design, electrode preparation and surface modification of new technology, the battery assembly areas such as research results obtained from the theory guiding the high-power nickel-hydrogen battery preparation, the current D-8Ah battery power density reached 1006W/Kg,energy density of 5 5Wh/Kg, more than the current international on the same level of D-type batteries.
At a new system of battery electrode materials prepared nonstoichiometric nano-Sn-based amorphous alloy anode, and its reversible lithium capacity and significantly improve the efficiency of the first Coulomb; found poly Triphenylamine high specific power characteristics and stable high-rate cycle . Security at the battery and put forward the use of voltage-sensitive membrane for reversible overcharge protection principle and technology.
The technology is expected to become the prevention of lithium-ion rechargeable battery, there were accidents, improve the safety of new methods. Recycling at the battery, the proposed leaching biology – membrane extraction Recycling used batteries in the resources of precious metals deal with ideas, lithium-ion battery in the leaching of cobalt and lithium concentrations were more than 50% for follow-up of liquid membrane extraction Recycling laid the technical foundation. Materials in battery design, optimum design and to explore the surface of the cathode material coated with the electrolyte material and the interaction of Lewis acid mechanism of spontaneous generation, which will be directly added to the nano-powder electrode material in the formation of modified electrode, significantly enhance the cathode material the actual specific capacity, cycle stability and rate performance and hot security, implementation of the design of electrode materials preparation technology innovation to improve the guiding philosophy. Research project in 2006 won the National scientific and technological progress second prize.apple a1175 , apple a1185 , apple m9324 , apple m8403 .
