A method for making a lithium ionic energy storage element, the method includes the steps of: (a) mixing a lithium ion donor, a positive electrode frame active substance and a binder with a predetermined weight ratio to form a mixture, and adding the mixture into a dispersant to form a positive electrode active substance, wherein the lithium ion donor includes lithium peroxide, lithium oxide or a combination thereof; (b) coating the positive electrode active substance on an aluminum foil to form a film, and baking the film to form a positive electrode; and (c) forming a lithium ionic energy storage element by assembling the positive electrode, a negative electrode having a negative electrode active substance and a porous separate strip interposed between the positive electrode and the negative electrode, and filling an electrolyte into the porous separate strip.

A method is provided to enhance efficiency of carbon felts in a flow battery. The carbon felts are directly immersed in a mixed acid solution. The carbon felts with the solution are heated at a low temperature and processed through sonication. On surface defects of the carbon felts, &#x2014;OH and C&#x2550;O functional groups are efficiently generated. The functional groups catalyze the redox reaction of vanadium ions. More active positions are obtained on the carbon felts through the activation treatment. Both of valence exchange and redox velocity of the vanadium ions are enhanced. Thus, the present invention has simple and fast processes with easily regulated experimental parameters for good modification without high temperature treatment but low cost.
