Issue 20/2020 - Lithium-ion battery materials successfully achieve fast charging

Recently, Professor Ji Xingxing's research group of the University of Science and Technology of China cooperated with the University of California, Los Angeles, the Institute of Chemistry, Chinese Academy of Sciences and other institutions to develop a new type of black phosphorus composite material, which can recover about 80% of the charge after 9 minutes of charging, and can still maintain 90% of the charge capacity after 2000 cycles, making it possible
to have the advantages of fast charging, high charge capacity and long life.
On October 9, the international authoritative academic journal "Science" published this result
.

If large-scale production of this material can be realized, matching cathode materials and other auxiliary materials can be found, and the design is optimized for cell structure, thermal management, lithium evolution protection, etc.
, it is expected to obtain lithium-ion batteries
with energy density of 350 watt-hours per kilogram and fast charging capabilities.

It is understood that lithium-ion batteries with an energy density of 350 watt-hours per kilogram can make the driving range of electric vehicles close to 1,000 kilometers
.
Combined with fast charging capabilities, the user experience of electric vehicles will be greatly improved
