Embodiment Construction

[0012] Below in conjunction with embodiment the present invention is described in further detail.

[0013] The alkaline batteries of Examples 1 to 5 are compared with the alkaline batteries of Comparative Examples 1 to 3. The mass percentage composition of the positive electrodes of Examples 1 to 5 and Comparative Examples 1 to 3 is shown in Table 1, and the composition of the positive electrodes of Examples 1 to 5 is as follows. The positive electrode of the alkaline battery uses a mixed conductive agent composed of graphene and graphite as the positive electrode conductive agent, and comparative examples 1-3 use graphite as the positive electrode conductive agent. Prepare the raw materials of Examples 1-5 and Comparative Examples 1-3 according to the mass percentage composition in Table 1, and make positive electrode rings respectively, and then assemble them into LR6 alkaline batteries, and test the initial Electrical properties and electrical properties after high-temperat...

Abstract

The invention discloses an alkaline battery which comprises a positive electrode and a negative electrode, wherein the positive electrode and / or the negative electrode comprise(s) graphene with the mass percent of 0.05-5%. By adopting graphene as a positive electrode conductive agent of the alkaline battery, not only is the internal resistance of the battery effectively reduced, but also the utilization rate of active substances is increased, the use amount of a positive electrode conductive material is also reduced, and the content of the active substances of the battery is increased, so that the discharge capacity and the comprehensive property of the battery are improved, and the battery is excellent in both large current property and medium / small current property; when graphene is adopted as a negative electrode additive, the flowability and the viscosity of the negative electrode can be improved, and meanwhile, a certain conductive function can be achieved in the medium / later discharge period of the battery, so that the utilization rate of the negative electrode active substances is increased.

Description

technical field [0001] The invention relates to a battery, in particular to an alkaline battery. Background technique [0002] Alkaline batteries usually include steel case, positive electrode ring, zinc paste, diaphragm tube, current collector, alkaline electrolyte, sealing ring, etc. The continuous development of digital products and digital technology of electronic devices is inseparable from high-power or pulse-discharged batteries with high-current discharge. Most of the traditional alkaline battery applications require batteries with superior performance in small and medium currents. However, the current alkaline battery technology field It is difficult to achieve both superior high current performance and superior medium and small current performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an alkaline battery with both superior large current performance and superior medium and small current perfo...
