Embodiment Construction

[0029] The present invention will further illustrate the technical solution of the invention through the following embodiments in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, a high-energy zinc-manganese battery includes a steel shell 1, a carbon nanotube conductive paper 2, a positive electrode ring 3, a zinc paste 4, a separator paper 5, a sealing ring 6, a copper nail 7 and a negative electrode cover 8.

[0031] The present invention adds a layer of carbon nanotube conductive paper 2 between the steel shell 1 and the positive electrode ring 3 as the current collector of the positive electrode, thereby improving the utilization rate of the battery positive electrode material and greatly increasing the discharge time of the zinc-manganese battery.

[0032] The production of carbon nanotube conductive paper:

[0033] Take 2g of carbon nanotubes and heat them in a microwave oven for 5 minutes. After chemical purification and surface modification, the c...

Abstract

The invention relates to a high-energy zinc-manganese battery which comprises a steel shell, a positive pole ring, zinc paste, diaphragm paper, a sealing ring, a copper nail and a negative pole cover. The high-energy zinc-manganese battery is characterized in that a layer of carbon nanotube conductive paper is additionally arranged between the steel shell and the positive pole ring to be taken as a current collector of a positive pole. The high-energy zinc-manganese battery has the advantages that 1, the affinity between the positive material and the current collector can be improved, and the positive material is more closely contacted with the steel shell, so that electrons can be well converged together on the carbon nanotube conductive paper; 2, a carbon nanotube has a high liquid absorption property so as to be used for well storing electrolyte, so that more electrolyte can be stored in the zinc-manganese battery, and the reaction can be continuously carried out.

Description

Technical field [0001] The invention belongs to the technical field of batteries. Background technique [0002] With the advent of the electronic age, more and more electronic products that require high-current continuous discharge and high energy enter the market, such as cameras, flashlights, calculators, and electric toys. Ordinary carbon batteries are difficult to meet capacity requirements; lithium-ion batteries are flammable and explosive due to the use of organic electrolytes, and are expensive; zinc-nickel batteries are also expensive due to lack of nickel resources. [0003] Alkaline zinc-manganese batteries can be mass-produced due to their reasonable structural design, and have excellent electrochemical performance and high cost performance. The capacity of alkaline zinc-manganese batteries is 4-5 times that of ordinary carbon batteries, and the price is very low. Large-scale application. [0004] As people's demand increases, it is more and more difficult for ordinary a...
