Solid lithium electrolyte-Li4Ti5O12 composites as anodes of lithium-ion batteries showing high-rate performance

New concept lithium-
The solid electrolyte and li4ti12 composite of ion conductive lithium titanium oxide as lithium-
Ion battery with excellent rate performance, can pass through 1-
Boiler burning technology. The as-
The size of the synthesized composite is micron, with dense properties, which effectively reduces the electrode-
The liquid electrolyte interface area, thus reducing the irreversible capacity during the first charge-discharge cycle and prolonging the cycle stability.
However, due to the close nano-mixing of the two phases, the composite material is rich in the two-phase boundary of lithium silicate and li4ti5. 0.
Obvious lithium
The ion conductivity of the composite electrode was significantly improved compared to the original li4ti12, due to the addition of the high lithium ion conductor lithium la titanium phase.
Results,-
The capacity of synthetic composites is as high as 113.
Even at a discharge rate of 40 °c, 5 mA h G-1, more than 200% of the original li4ti5. 0.
This concept is universal and may also be applicable to other electrode materials, thus providing a new approach to the development of high rates
Performance electrode of lithiumion batteries.
