Abstract
The present invention provides a new organic-inorganic (PDMcT+PANI)/V2O5 composites electrode material in which two different organic polymers are intercalated into the V2O5 interlayer, which shows higher discharge capacity than each isolated polymers and V2O5. Therefore, it can be used as a cathode in secondary lithium battery.
Claims4
A method for manufacturing an organic-inorganic composite for use as a cathode of a secondary lithium battery, the method comprising the following steps of:
- (a) manufacturing a V2O5 xerogel powder;
- (b) dissolving the V2O5 xerogel powder in distilled water to form V2O5-water solution;
- (c) dissolving DMcT molecule in organic solvent to form DMcT solution;
- (d) adding the V2O5-water solution to the DMcT solution
- (e) adding aniline to the resultant of (d);
- (f) reacting the resultant of (e) for 24 hours at a room temperature and then filtering and washing;
- and
- (g) drying the resultant of (f) under vacuum at temperature ranging from room temperature to 80° C.
