As the most widely used rechargeable battery at the moment, lithium
ion batteries have a very high energy density. Tin, silicon and other
non-carbon materials are expected to replace the current commercial graphite oxide powder
as a new generation of anode electrode materials, significantly
increasing the mass energy density of lithium-ion batteries (Whkg-1),
but its huge volume expansion has severely limited its volumetric
performance advantages.
The carbon cage structure constructed of carbon nanomaterials is considered to be the main means to solve the problem of large volume expansion when the non-carbon anode electrode material is intercalated with lithium; however, in the process of constructing the carbon buffer network, too many reserved spaces are often introduced, resulting in the electrode materials The density is greatly reduced, which limits the anode volume performance of lithium-ion batteries.
Prof. Yang Quanhong's research team has made breakthroughs in the design of anode materials for high-volume energy density lithium-ion batteries. Based on the assembly of graphene interfaces, he invented the precise and customized sulfur template technology for dense porous carbon cages. In the process of constructing a dense graphene network using capillary evaporation technology, they introduced sulfur as a flowable volume template to complete the customization of the graphene carbon coating for non-carbon active particles.
By adjusting the amount of sulfur template used, the three-dimensional graphene carbon cage structure can be precisely controlled to realize the "fitting" of the non-carbon active particle size, thereby acting as a lithium on the basis of effectively buffering the large volume expansion of the non-carbon active particles intercalating lithium. The lithium ion battery anode shows excellent volume properties.
The sulphur template method is proposed in the three-dimensional graphene dense network, and uses the sulfur as the "Transformers"-like fluidity, amorphous, and easy to remove, to achieve non-carbon active particles in the carbon cage structure. Tin oxide nanoparticles tightly coated.
This kind of carbon-non-carbon composite electrode material having a suitable reserved space and maintaining a high density can contribute a very high volumetric capacity, thereby greatly increasing the volumetric energy density of the lithium ion battery and making the lithium ion battery smaller.
