Description
Technical Field
The invention relates to the technical field of magnesium-manganese or zinc-manganese batteries, in particular to a battery structure with a composite anode.
Technical Field
In the prior art, magnesium manganese or zinc manganese batteries generally adopt a magnesium or zinc anode integral cylinder production process, and because magnesium or zinc is used as an anode and a container, the actual utilization rate of non-ferrous magnesium or zinc in the batteries is only about 30 percent. When magnesium is used as both the container and the anode, the magnesium hydroxide is increased in volume to cause cell rupture, so that the magnesium alloy cylinder has to be thickened by times to cause more waste.
The battery isolation paper in the prior art has the defect of large internal resistance, so that the discharge efficiency is low.
Disclosure of the invention
The invention aims to provide a composite anode battery which is suitable for a magnesium-manganese battery and a zinc-manganese battery. Due to the adoption of the isolation layer with the composite structure, the internal resistance can be reduced, and the discharge efficiency of the battery is higher. And mercury and cadmium are not added, so that the method is more in line with the requirement of environmental protection. The production cost of the battery is reduced by more than 25%, and the battery is beneficial to saving resources.
The technical scheme adopted for achieving the purpose is as follows: the composite anode battery comprises a conductive outer barrel, a manganese dioxide cathode, a magnesium alloy or zinc alloy anode, an isolating layer, a carbon rod, an end cover and an insulating pad; the method is characterized in that: the magnesium alloy or zinc alloy anode is a magnesium alloy or zinc alloy inner sleeve which is arranged in the conductive outer cylinder and forms a composite anode with the outer cylinder; an isolating layer is arranged between the composite anode and the manganese dioxide cathode powder.
The isolation layer is a composite isolation layer, and the composite isolation layer is provided with low-density wood pulp paper, a PVA layer and high-density wood pulp paper which are arranged outwards and inwards in sequence. The PVA layer is used as a bonding layer of two layers of wood pulp paper and forms a moisturizing layer together with the low-density wood pulp paper.
The conductive outer cylinder can be an aluminum alloy outer cylinder or a conductive plastic outer cylinder.

The isolating layer can adopt pulp layer paper, a paste layer in the prior art or adopt a composite isolating layer in the embodiment, and the composite isolating layer is provided with low-density wood pulp paper, a PVA layer and high-density wood pulp paper which are arranged outwards and inwards (from the outer barrel to the inside) in sequence. Wherein, the PVA layer is also used as a bonding layer of two layers of wood pulp paper and forms a moisturizing layer together with the low-density wood pulp paper.
