摘要:
A nonaqueous battery cell includes a casing, a negative electrode provided in the casing, the negative electrode including lithium ions intercalated into a single crystal of a titanium dioxide (TiO2), in the rutile phase, with concentration on the order of 1016 cm−3, a positive electrode provided in the casing, a separator separating the negative electrode from the positive electrode, and an electrolyte disposed in the casing.A method of manufacturing a negative electrode material to be used in a nonaqueous battery cell includes the steps of burying a titanium dioxide (TiO2) into a lithium hydroxide powder, heating, in a furnace, the titanium dioxide buried in the lithium hydroxide powder at about 450° Celsius for 6 or more hours, and isolating a single lithium ion within a C-axis channels aligned along the crystallographic direction of the single TiO2 crystal.
