NOVELTY - Method for controlling capacity of layered lithium-free anode material involves testing interlayer distance of layered electrode material and recording as d1, selecting electrolyte containing lithium ion as working electrolyte, when the interlayer distance of the layered electrode material is more than 1 nm, and selecting electrolyte containing cation with diameter d2, as working electrolyte, when the interlayer distance of the layered electrode material is less than 1 nm. Specific capacity of the layered electrode material is increased, when difference between d1 and d2 is more than 0 nm and less than 0.4 nm. USE - Method for controlling capacity of layered lithium-free anode material. ADVANTAGE - The method enables researching relationship between specific capacity of the layered electrolytic material with different interlayer distances and electrolyte cation diameter, and obtaining lifting of specific capacity of the layered electrolytic material for realizing different interlayer spacing by adjusting and controlling cation, so as to quickly prepare efficient working electrolyte for selected layered electrolytic material with important research and application value.
