Higher-dimension classification SnO2Synthesis, doping, carbon coating processing and its application on lithium ion battery of micro-nano structure.And this is specially
Sharp first inventor is also successfully prepared the SnO that nano structured unit is constructed2With SnO hierarchies, Sn (II) doping or and Ti
(IV) SnO of codope2The flower-shaped or wire hierarchy of nanometer sheet assembling, finds by constructing three-dimensional hierarchical organization or mixing
The SnO of miscellaneous modification2Nano material, its chemical property can be improved to a certain extent, but its capacity increases with cycle-index
Rapid decay.To find out its cause, it is the tin-based material size prepared still very greatly (tens or even hundreds of nanometers), and Li-Sn is closed
Volumetric expansion is up to 300% caused by aurification.Therefore, further reduce nano material size to quantum rank (10nm with
It is interior), and it is uniformly firmly scattered in stabilized matrix, it is expected to the critical defect for solving such alloy material.
