Abstract

The invention discloses a zinc-manganese battery, and particularly relates to a zinc-oxide-containing alkaline zinc-manganese battery and a preparation method thereof. The zinc-oxide-containing alkaline zinc-manganese battery comprises a negative electrode zinc paste, a positive electrode ring, a separation membrane, and electrolytic solutions respectively used for the positive electrode ring, thenegative electrode zinc paste and the separation membrane, wherein the negative electrode zinc paste is prepared from zinc powder, zinc oxide, sodium silicate and a binder, the positive electrode ring is prepared from electrolytic manganese dioxide and an electric conduction agent, the separation membrane is prepared from a paper pulp or fiber mixture, all the electrolytic solutions are potassiumhydroxide aqueous solutions, and the electrolytic solution for the negative electrode zinc paste contains zinc oxide. According to the present invention, the zinc-oxide-containing alkaline zinc-manganese battery is provided under the premise of the increasing demand of the market on the high-power alkaline zinc-manganese batteries, such that the utilization rate of the zinc powder is increased while the hydrogen evolution of the zinc powder is inhibited to a certain extent; and by matching the optimized battery positive electrode, the optimized battery negative electrode and the alkali liquidconcentration ratio, the alkaline zinc-manganese battery produced according to the formula has the significantly-increased high-current discharge performance.

Description

technical field [0001] The invention relates to a zinc-manganese battery, in particular to an alkaline zinc-manganese battery containing zinc oxide and a preparation method thereof. Background technique [0002] Among the existing battery systems, alkaline zinc-manganese batteries have been popularized and applied in a wide range due to their high energy density, low price, and good portability, and have always occupied the mainstream of my country's primary battery market. With the development of science and technology and production, the diversification of small electrical appliances and the increasing number of high-power portable electrical appliances, people have higher and higher requirements for the battery's heavy-load discharge performance, so it has heavy-load, high-current, strong continuous discharge capabilities, The demand and production of alkaline manganese batteries with excellent leak-proof performance, long storage time and good low-temperature performan...
