The feldspars contribution to whole rock phosphorus is related with the crystallization of phosphate accessory minerals,such as ambl ygonite.If without amblygonite in crystallization assemblage,the feldspars con tribute about 76%of whole-rock phosphorus,otherwise the feldspars contribute about 31%of whole-rock phosphorus.

But the concentration of Li2CO3 remains nearly consistent and a new component, CH3OLi, is found in SEI. It can be concluded from these results that anisole reacts with the reduction product of EC and DEC, RCO3Li, in the first process of Li＋ intercalating into the carbon electrode. The obtained CH3OLi is helpful in building up a more effective and stable SEI of the carbon electrode, reducing the cointercalation of solvent molecular. All these contribute to the improvement of the cycle performance of lithium-ion battery.
