Abstract: A phosphorated polymer includes a conductive polymer main-chain and a side-chain connected to the conductive polymer main-chain. The side-chain includes an electrochemically active phosphorated group Pm. A method for making the phosphorated polymer and a lithium-ion battery using the phosphorated polymer is also provided.

Abstract: A phosphorated composite capable of electrochemical reversible lithium storage includes a conductive matrix and a red phosphorus. The conductive matrix includes a material being selected from the group consisting of conductive polymer and conductive carbonaceous material. A weight percentage of the conductive matrix in the phosphorated composite ranges from about 10% to about 85%. A weight percentage of the red phosphorus in the phosphorated composite ranges from about 15% to about 90%. A method for making the phosphorated composite and a lithium-ion battery using the phosphorated composite is also provided.

Abstract: A method of making a clarified tea extract to reduce the cloudiness of a beverage containing the clarified tea extract by producing an aqueous tea extract that contains tea insolubles, adding a food-acceptable acid and a salt to the aqueous tea extract simultaneously and thereafter holding the aqueous tea extract with minimal agitation to produce a precipitate and clarifying the aqueous tea extract. Another method of making a clarified tea extract by adding a base to extraction water, contacting the base-containing extraction water with a tea source to produce an aqueous tea extract, adding a food-acceptable acid to the aqueous tea extract, and thereafter holding the aqueous tea extract with minimal agitation to produce a precipitate and clarifying the aqueous tea extract.
