The invention discloses a battery and a fabrication method of a pole plate thereof. The battery comprises a negative electrode (1), a positive electrode (3) and a separator (2), wherein the separator(2) is arranged between the negative electrode (1) and the positive electrode (3), the negative electrode (1) comprises a negative pole plate or a negative carbon film, the negative pole plate takes acopper foil with holes as a negative current collector, the positive electrode (3) comprises a positive carbon member or a sulfur-containing carbon film, and the positive carbon member is coated witha positive active substance. With the battery disclosed by the scheme, the defects that the active substance in the prior art is easy to fall off, the energy density of the battery is low and the battery is inconvenient to use can be overcome, and the beneficial effects that the active substance is difficult to fall off, the energy density of the battery is high and the battery is convenient to use are achieved.
