Magnesium alloy storage battery

Abstract

The invention discloses a magnesium alloy storage battery which comprises a battery shell, partition layers and an upper cover. The interior of the battery shell is divided into a plurality of reaction chambers. Each reaction chamber is covered with the corresponding partition layer which is provided with a plurality of water inlets. The upper cover is matched with the battery shell and provided with a water injecting hole. In each reaction chamber, a tinplate sheet is placed on one side of the reaction chamber to serve as a battery cathode, the surface of the tinplate sheet is wrapped by a conductive electrode film, a magnesium plate is placed on the other side of the reaction chamber to serve as a battery anode, the surface of the magnesium plate is wrapped by glass fiber partition plate paper, and the space between the cathode and the anode is filled with a cathode powder material which is then compacted. Each reaction chamber serves as an independent battery. The cathode plates and the anode plates of the reaction chambers are connected with one another in series or in parallel through conductive rods, and therefore the requirements of different output voltages and different output currents can be met. As a storage type battery, the magnesium alloy storage battery has the storage life of 20 years or more; the magnesium alloy storage battery can be used by injecting clean water or other liquid through the water injecting hole before use and activating the magnesium alloy storage battery for 1 min, and the working voltage is quite stable.

Description

technical field [0001] The invention relates to accumulators, in particular to a reserve battery. Background technique [0002] Commercially available batteries currently on the market are generally lead-acid batteries. The advantages of lead-acid batteries are mature technology and rechargeable use. However, lead-acid batteries use lead and lead oxides as electrodes, and sulfuric acid solution as electrolyte. After the battery is discarded, it will seriously pollute the water and soil environment and cause great damage to the environment; the density of lead is very large, and a medium-capacity (100AH) lead-acid battery The weight can reach 30kg, and it cannot be carried with you; the life of lead-acid batteries is generally 5 years, which makes it necessary to replace all lead-acid batteries in some applications, such as the backup power supply for communication base stations, every 5 years , most of the lead-acid batteries have never been used, resulting in a great wast...

However, lead-acid batteries use lead and lead oxides as electrodes, and sulfuric acid solution as electrolyte. After the battery is discarded, it will seriously pollute the water and soil environment and cause great damage to the environment; the density of lead is very large, and a medium-capacity (100AH) lead-acid battery The weight can reach 30kg, and it cannot be carried with you; the life of lead-acid batteries is generally 5 years, which makes it necessary to replace all lead-acid batteries in some applications, such as the backup power supply for communication base stations, every 5 years , most of the lead-acid batteries have never been used, resulting in a great waste, and the cost of manpower and material resources to replace the batteries of all base stations in urban areas and suburbs is also considerable
