Abstract
The invention relates to an anode for a lithium battery and a preparation method thereof. The anode for the lithium battery comprises the following components: acetylene carbon black, polytetrafluoroethylene, alcohol and lithium chloride. In the invention, the lithium chloride is added into the anode for the lithium battery, so that the structure of a carbon cathode is improved, the porosity is increased, and the high current discharging performance and the low temperature performance of the battery are greatly improved.
Description
Technical field
The present invention relates to a kind of anode for lithium battery and preparation method thereof.
Background technology
At present, its composition of lithium battery anode includes acetylene carbon black, polytetrafluoroethylene and alcohol.Its preparation method is poured polytetrafluoroethylene, alcohol dispersion liquid into to acetylene carbon black, and the mould of packing into after above raw material is stirred is squeezed into cylindric or is squeezed into sheet, and the carbon bag that will wet removes alcohol, fibrillation, and size cuts, uses according to the rules.Use the lithium battery of this anode for lithium battery not have big electric current and cryogenic property.
Summary of the invention
Purpose of the present invention just provides a kind of have heavy-current discharge and the good anode for lithium battery of cryogenic property.
Technical scheme provided by the invention is:
A kind of anode for lithium battery, its composition includes acetylene carbon black, polytetrafluoroethylene, alcohol and lithium chloride.
Preferably, the weight of lithium chloride is the 0.5%-3% of total weight.
A kind of preparation method of anode for lithium battery:
1) with required weight LiCl be added to stir well in the alcohol even;
2), the preparation, polytetrafluoroethylene, alcohol LiCl dispersion liquid are poured into to acetylene carbon black;
3), the mould of packing into after above raw material is stirred is squeezed into cylindric or is squeezed into sheet;
5), will wet the carbon bag except that alcohol, fibrillation;
6), size cuts, uses according to the rules.
The present invention adds lithium battery anode with lithium chloride, having improved carbon cathode structure and porosity increases, and has improved the big electric current of battery greatly and has put performance with low temperature.
Embodiment
A kind of anode for lithium battery, its composition includes acetylene carbon black, polytetrafluoroethylene, alcohol and lithium chloride.Wherein the weight of lithium chloride is 2% of total weight.
A kind of preparation method of anode for lithium battery:
1) with required weight LiCl be added to stir well in the alcohol even;
2), the preparation, polytetrafluoroethylene, alcohol LiCl dispersion liquid are poured into to acetylene carbon black;
3), the mould of packing into after above raw material is stirred is squeezed into cylindric or is squeezed into sheet;
5), will wet the carbon bag except that alcohol, fibrillation;
6), size cuts, uses according to the rules.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
