Description
Technical Field
The invention relates to a magnesium-oxygen battery, in particular to a magnesium-oxygen battery used under seawater.
Background
In recent years, with the advancement of science and technology, people have further improved understanding of ocean resources, ocean engineering technology has also been greatly developed, and ocean development is becoming an important strategic plan of many countries. Ocean remote sensing technology, ocean navigation technology, deep sea exploration technology, ocean military technology and the like are all independent of power supply. Due to the particularity and complexity of practical working conditions under the sea, the conventional primary battery and secondary battery (such as a lead-acid battery, a nickel-metal hydride battery, a silver-zinc battery, a lithium ion battery and the like) are difficult to meet the requirements of novel underwater equipment on a long-life, high-capacity, safe and reliable power supply.
A typical magnesium-oxygen battery includes metallic magnesium or magnesium alloy, an oxygen cathode, and an electrolyte (e.g., KOH solution, naCl solution, etc.) of an alkali metal salt (or base thereof) filled between the anode and the cathode. During the discharging process of the battery, oxygen and water in the electrolyte undergo a reduction reaction at an oxygen cathode to generate anions (such as OH) - ) The anions migrate through the electrolyte to the metal anode and react with the magnesium metal to generate electrons. For example, when using magnesium metalWhen the metal-oxygen battery system is used as an anode and a sodium chloride solution is used as an electrolyte, the electrode reaction and the electrode reaction potential on two electrodes during the discharge process of the battery are as follows:
and (3) anode reaction: mg → Mg 2+ +2e - E＝-2.37V
And (3) cathode reaction: o is 2 +2H 2 O+4e - →4OH - E＝0.40V
And (3) battery reaction: mg +1/2O 2 +H 2 O→Mg(OH) 2 E＝2.77V
First, the magnesium-oxygen battery has a higher specific energy (in units of W · h/L or W · h/kg) and can provide a higher output voltage (1.5 to 3V) than conventional primary and secondary batteries. And secondly, the metal magnesium is abundant in reserve, cheap and easily available, the cathode oxygen reduction catalyst is non-noble metal, and the whole battery is simple in structure and easy to prepare, so that the total cost of battery production is greatly reduced. Thirdly, another important characteristic of the magnesium-oxygen battery is that the magnesium-oxygen battery can adopt a mechanical charging mode, namely after the anode magnesium metal is completely consumed, the battery can be continuously powered by using new magnesium metal, the charging time is very short, the battery can be completed in only a few minutes, and the service life of the battery is prolonged. In addition, environmental protection is another important advantage of magnesium-oxygen batteries. The chemical power sources commonly used at present cause pollution to the environment to different degrees, such as mercury in a zinc-manganese battery, lead in a lead-acid battery, cadmium in a nickel-cadmium battery, and the products of the metal-oxygen battery after reaction are nontoxic and have no pollution to the environment, which has profound significance to ecological protection and environmental protection.
The magnesium-oxygen battery can utilize seawater as electrolyte, so that the magnesium-oxygen battery can be used as a power supply for submarine equipment to provide electric energy for the submarine equipment. The seawater is used as the electrolyte of the battery, and the extra electrolyte is not needed, so that the specific energy of the battery is greatly improved. However, two major problems with seawater cells are the problem of oxygen supply and the problem of cathode side oxygen pressure balance with the electrolyte (seawater).
US patent No. US4184009 provides a floating metal-air battery having a metal anode immersed in a seawater electrolyte, a cathode above the water surface and exposed to air, and a paper-like material of glass fiber and polyvinyl chloride fiber composite filled between the anode and cathode. The paper-like material is filled with an electrolyte. This cell requires oxygen from the air as a depolarizer and its cathode must be in communication with the air and therefore can only be used in sea-working equipment.
Chinese patent No. CN1543001A provides a magnesium seawater battery, which uses seawater as electrolyte and uses dissolved oxygen in seawater as cathode depolarizer, but the battery has a simple structure, but has a low cathode efficiency, a small working current density, and a large cathode area, which also limits the application range, and is not suitable for electric devices requiring high power, such as underwater power supplies.
The peroxide reacts with water to produce oxygen, which can serve as a source of oxygen. Especially, the oxygen content of the hydrogen peroxide is high, and the hydrogen peroxide is often used as an oxygen supply material. The reaction principle is as follows:
2H 2 O 2 →2H 2 O+O 2
the oxygen generation principle by alkaline earth metal reaction after alkali metal is as follows:
Na 2 O 2 +H 2 O→2NaOH+1/2O 2
2CaO2+H2O→2CaOH+3/2O 2
the invention provides a method for providing oxygen for a battery by decomposing and preparing oxygen by using hydrogen peroxide as an oxygen source. In order to utilize the water produced by the decomposition of hydrogen peroxide, an alkali metal or alkaline earth metal is reacted with water as a secondary oxygen supply.
