towards high capacity li-ion batteries based on silicon-graphene composite anodes and sub-micron v-doped lifepo 4 cathodes - 3.7 volt lithium ion battery
Lithium iron phosphate (LFP)
As a cathode material for lithium ion batteries, promising performance is shown (LIBs)
By overcoming the rate performance problems caused by limited electronic conductivity. Nano-sized vanadium-doped LFP (V-LFP)
Using the supercritical water as the reagent, the continuous water heating process was used to synthesize.
The atomic percentage of the mix determines the shape of the particles. 5 at.
Plates and sticks for mixing-
Show the best electrical performance and good rate performance like morphologyLi.
Specific capacity of> mah g-1 is implemented.
In order to increase the capacity of the full battery, V-
LFP is made with a cheap Micron
Metallurgical grade Si-
Containing anode.
This electrode is capable of having a reversible capacity of approximately mah g-1 in more than 150 cycles
Li, the performance has been improved due to the addition of a small amount of graphene (FLG)
To improve the conductivity, tensile properties, thereby improving the stability of the composite.
Cathode material synthesis and electrode formulation are scalable and inexpensive and are suitable for the manufacture of larger format batteries suitable for grid and transport applications.
