Negative electrode and zinc secondary battery

A negative electrode for use in a zinc secondary battery, comprising:

• (A) ZnO particles;
• and
• (B) at least two selected from the following group consisting of
• (i) metallic Zn particles having an average particle size D50 of 5 to 80 μm,
• (ii) at least one element selected from the group consisting of In and Bi, contained in the form of at least one of a metal particle, an oxide particle, and a hydroxide particle, and
• (iii) a binder resin having a hydroxyl group,
• wherein when the negative electrode comprises metallic Zn particles, the content of metallic Zn particles is in an amount of 10 to 90 parts by weight, based on the content of the ZnO particles is 100 parts by weight,
• wherein when the negative electrode comprises In and when the content of elemental In is converted to a content of In2O3, the content of In2O3 is 0.3 parts by weight or more to 2.4 parts by weight or less, based on the content of the ZnO particles being 100 parts by weight,
• wherein when the negative electrode comprises Bi and when the content of elemental Bi is converted to a content of Bi2O3, the content of Bi2O3 is 0 parts by weight or more to 0.6 parts by weight or less, based on the content of the ZnO particles being 100 parts by weight, and
• wherein when the negative electrode comprises the binder resin, the content of the binder resin on a solid basis is 0.01 parts by weight or more to 0.05 parts by weight or less, based on the content of the ZnO particles being 100 parts by weight.
