Description

Water injection zinc alloy battery

Technical Field

The utility model relates to a battery technology field, concretely relates to water injection zinc alloy battery.

Background

Compared with zinc alloy, the magnesium alloy has lower electrode potential, smaller electrochemical equivalent and better conductivity, and is a more ideal battery anode material. However, since magnesium alloys are too active electrochemically, several drawbacks arise when used as battery anode materials:

1. the magnesium alloy is easy to react with nitric acid to generate undegradable strong oxide and heavy metal residue (magnesium salt), which is not only not environment-friendly, but also can cause the battery to have short repeated service life,

2. residues generated by the magnesium alloy can block a water injection hole of the shell, so that the corrosion and expansion are caused, and the battery explosion phenomenon is seriously caused.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned weak point that exists among the prior art, the utility model aims to provide a water injection zinc alloy battery of structural design is reasonable, uses the environmental protection, long service life.

The utility model discloses a following technical scheme realizes: water injection zinc alloy battery, including being cylindric iron-clad, iron-clad one end is the opening, and its other end is the blind end, is equipped with a zinc section of thick bamboo in the iron-clad cavity, zinc section of thick bamboo cavity intussuseption is filled with the catalyst through the paper membrane cladding insert a carbon-point perpendicularly in the catalyst, and its other end stretches out plastic cover and this pot head and is equipped with the metal cap, be equipped with between zinc section of thick bamboo upper end and the iron-clad opening and closely cooperate the plastic lid with iron-clad inner wall, the plastic is covered and is equipped with a water injection through-hole at least, the plastic lid lower extreme is equipped with the diaphragm that is used for sealing the water injection through-hole, and the diaphragm passes through the plastic ring and supports fixedly, form.

Further, be equipped with the plastics circle that is used for supporting the diaphragm between paper membrane upper end and the diaphragm.

Furthermore, the catalyst of the present invention adopts manganese dioxide and alkaline material to mix.

Furthermore, the alkaline material of the present invention is any one of potassium hydroxide or sodium hydroxide.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. the utility model discloses water injection zinc alloy battery does not corrode when keeping under dry sealed condition, has good storage performance.

3. The utility model discloses the catalyst does not adopt acidity, can not produce residue and heavy metal, can not plug up the water injection through-hole, can not cause the battery to send out the phenomenon of expanding to improve battery and relapse life.

2. After the battery is dried, sealed and stored for 60 months, the discharge capacity of the battery is not lower than 99 percent of the initial discharge capacity in terms of average discharge time.
