Abstract: An energy storage device made of an aluminum electrode includes a positive electrode, a negative electrode, a separator, and an electrolyte. The negative electrode is the aluminum electrode. The separator is arranged between the positive electrode and the negative electrode. The electrolyte is arranged between the positive electrode and the negative electrode and partly located in the separator. The electrolyte includes an aluminum halide and an ionic liquid. The aluminum halide is configured to produce a faradaic pseudo-capacitance reaction in the energy storage device. The ionic liquid is configured to cooperate with the faradaic pseudo-capacitance reaction in the energy storage device.

Abstract: A battery includes an electrolyte and a positive electrode. The electrolyte is configured to produce active substance. The active substance in the battery is intercalated to a lattice structure of the positive electrode to generate power of the battery.

Abstract: An aluminum battery packaging film includes a heat-sealing layer, wherein a material of the heat-sealing layer includes modified polyethylene terephthalate, polycarbonate, polyimide, or a combination thereof.

Abstract: A dispersion method of slurry for aluminum battery includes at least the following. A first dispersion liquid with active powder and a second dispersion liquid with conductive powder are provided separately, wherein the second dispersion liquid is different from the first dispersion liquid. The first dispersion liquid and the second dispersion liquid are mixed and dispersed by one or more of three-roll rolling, ball milling, centrifugal stirring, and planetary stirring to make a slurry.
