Abstract

The invention relates to a liquid activated zinc manganese paper battery and a preparation method of the battery; the liquid activated zinc manganese paper battery is formed by sequentially laminating a zinc cathode, a piece of fiber paper absorbed with electrolyte, a piece of coated layer paper coated with MnO2 active slurry, and a carbon collector; the preparation method comprises the steps of: preparing the electrolyte according to the mass ratio of ZnCl2 to NH4Cl to CaCl2 of (5-30): (5-50): (3-10); soaking the fiber paper into the electrolyte, and drying at 40-50 DEG C for later use; firstly mixing MnO2, a conductive agent and an additive according to the mass ratio of (80-90): (10-20): (0.1-1.0), then carrying out ball-milling to obtain MnO2 mixed powder; adding deionized water into the MnO2 mixed powder to prepare the MnO2 active slurry, then blade coating the MnO2 active slurry onto the surface of the coated layer paper, and drying at 40-50 DEG C for later use; sequentially overlying the fiber paper absorbed with the electrolyte, the coated layer paper coated with the MnO2 active slurry and the carbon collector on the surface of the zinc foil cathode, and leading out a positive pole lead and a negative pole lead; and finally, carrying out vacuum encapsulation by a plastic film. The battery disclosed by the invention is excellent in storage performance and can be stored for a long time without becoming invalid; and the voltage of the single battery reaches 1.5-1.6V.

Description

technical field [0001] The invention relates to a liquid-activated zinc-manganese paper battery and a preparation method thereof. Background technique [0002] Zinc-manganese battery has the advantages of low price and convenient use, and it is a kind of battery that is often used in daily life. The paper battery is a new type of battery developed in recent years. It is based on paper and has the characteristics of flexibility and thinness. The paper battery produced by Israel Power Paper is also a kind of battery made of zinc and MnO. 2 Composition, using industrial standard printing technology, printing electrode materials on paper, single paper battery can reach 1.5v, this battery is characterized by extremely low cost, flexible shape and size, and easy to use. Enfucell Battery Company has also developed a paper battery whose composition and structure are similar to those of Power Paper Company. Paper batteries are currently being used in miniature electronic devices, e...
