1. A method comprising:
preparing a compound comprising Li1.25Cr0.25Ti1.5O4 (LCTO) or Li1.25Al0.25Ti1.5O4 (LATO), and a second composition of matter a spinel crystal structure electrode material selected from one of LiNi0.5Mn1.5O4 (LNMO), LiMn2O4, or Li4Ti5O12, and further combined with composites with Li3BO3 (LBO), wherein the spinel crystal structure electrode material comprises a single-phase spinel structure;
dissolution of precursors of the compound into aqueous citric acid and nitric acid to obtain an aqueous solution;
heating the aqueous solution to form a precipitate; and
heating the precipitate at 400-1100° C.
