On October 11, according to the Chinese Academy of Sciences, Liu Jinhuai of the Institute of Intelligent Machinery of the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences and Liu Jinyun, an associate researcher in the research group of Huang Xingjiu, made new achievements in the development of high-performance graphene lithium-ion batteries, and developed three-dimensional graphene nanocomposite lithium-ion battery materials
with high capacity and long life.
From portable electronic devices to new energy electric vehicles, there is an urgent need
for high-performance lithium-ion batteries.
As the core of lithium-ion batteries, electrode active materials generally require high capacity and energy density, long-term cycle stability and safety
.
Liu Jinyun et al.
through the University of Illinois at Urbana-Champaign and the Hefei Research Institute of the Chinese Academy of Sciences to develop a composite battery material based on three-dimensional graphene, with high active material loading, short ion electron transport path, and the electrode material assembly into the battery does not need to use any binder and conductive agent and other additives, the battery has high capacity and excellent cycle stability
.
In addition, the structural design of the three-dimensional graphene composite battery material can also be applied to the anode material of lithium-ion batteries, such as the development of graphene/silicon composite anode, showing good versatility
.
Market participants believe that the breakthrough in the research and development of graphene lithium-ion battery materials is expected to bring benefits to the application and promotion of the graphene industry again
