Embodiment 1

[0019] A novel seawater-activated battery, the seawater-activated battery uses a magnesium alloy sheet as a negative electrode, and conductive polyaniline as a positive electrode, wherein the rolling method of the magnesium alloy sheet includes the following steps:

[0020] (1) Select AZ33m cast plate, and mill its surface, and use a polishing machine to partially polish the parts that still have a small number of cracks;

[0021] (2) Turn on the heating raceway kiln, set its temperature to 350°C, heat the billet with the furnace, set the roll temperature to 150°C, and carry out the first rolling after a total of 1.5h of heating and holding time, and keep it warm for 0.5h after rolling. The temperature of the heating raceway pit is lowered by 5°C every time rolling, the speed of the roll is 0.5m / s, and the amount of pressing is 20% each time. After rolling for 3-6 times, it is cut along the rolling direction, returned to the furnace for heating, and then vertically Rolling in ...

Abstract

The invention discloses a novel sea-water activated battery. According to the sea-water activated battery, a magnesium alloy sheet serves as a negative pole, and conductive polyaniline serves as a positive pole. A method for rolling the magnesium alloy sheet comprises the steps of casting a sheet material by using AZ33m, carrying out pretreatment on the sheet material, starting up a heating roller kiln, carrying out kiln heating on stock, carrying out primary rolling at the rolling roller temperature of 150 DEG C to 200 DEG C after heating-up and heat insulation time which is 1.5 to 2 hours in all, carrying out heat preservation for 0.5 to 0.8 hour after rolling, lowering the temperature of the heating roller kiln by 5 DEG C to 10 DEG C after every rolling, carrying out cutting along a rolling direction after 3 to 6 times of rolling, carrying out melt-down heating, and carrying out rolling along a direction vertical to the rolling direction until the thickness of the sheet reaches 2mm to 5mm. The novel sea-water activated battery provided by the invention has the characteristics of high voltage and high current, thereby having an extremely extensive application prospect.

Description

Technical field: [0001] The invention relates to the technical field of batteries, in particular to a novel seawater activated battery. Background technique: [0002] The battery is the main component of the power plant on the electric torpedo, which provides energy for the propulsion motor. According to the use of the torpedo power unit, the torpedo battery should meet the following requirements: high specific energy, high specific power, long service life, low price, and convenient use and maintenance. One of the keys to the development of torpedoes is to improve the performance of the power battery and reduce the cost. [0003] Magnesium electrode materials have many advantages such as low cost, non-toxic, non-polluting, stable discharge voltage, high specific energy, high specific power, abundant resources, and renewable, and have attracted widespread attention. However, it has not been widely used. One of the main reasons is that the polarization and corrosion of magn...
