It is reported that the project led by Tianjin Lishen Battery Co.
, Ltd.
"High Specific Energy Density Lithium-ion Power Battery Development and Industrialization Technology Research" has completed the development of a power battery cell with an energy density of 260Wh/kg, which is 30%
higher than the current power battery commonly used in electric vehicles.
The project team has carried out in-depth research and technical research on improving the weight ratio energy density of power batteries and greatly improving cycle life, including the development of new high-nickel cathode materials, silicon-carbon composite anode materials and new electrolytes
.
At present, a single cell with a weight ratio energy density of 260Wh/kg has been developed, and the capacity retention rate reaches 83.
28% after 350 charge-discharge cycles; At the same time, samples of power batteries with energy densities of 280Wh/kg and 300Wh/kg were developed
.
The project breaks through the industrial processing and preparation technology of high energy density cells, forms a standardized platform in material development, cell preparation process technology, electrochemical performance and safety performance testing, etc.
, and the research results will be further expanded and applied to square and round power batteries, covering a full range of power battery products
