Judging from the current market, nickel-metal hydride batteries are in great demand. Most researchers are studying how to maximize the performance of nickel-metal hydride batteries so that they can have sufficient energy to meet the load and improve the efficiency of the entire battery. However, in the design Many of the processes in the process cannot meet the performance of the product. In terms of technology, if there is cocoa, from the current market point of view, the demand for nickel-metal hydride batteries is huge. Most scientific researchers are studying how to maximize the efficiency of improving the performance of nickel-metal hydride batteries, which can There is sufficient energy to meet the load and improve the efficiency of the entire battery. However, many of them cannot meet the performance of the product during the design process. In terms of technology, there are cocoa requirements.

Nickel metal hydride battery is also called nickel metal hydride battery. It is mainly a rechargeable battery composed of hydrogen storage alloy negative electrode, nickel positive electrode, potassium hydroxide electrolyte and separator. The essential difference between it and nickel cadmium battery is only in the negative electrode material. s difference. The voltage of this battery is exactly the same as that of the nickel-cadmium battery, which is 1 2V. It can also be used directly on nickel-cadmium machinery. The negative electrode material of the nickel-metal hydride battery, the hydrogen storage alloy, is an alloy formed of two metals, A and B. Metal A can A large amount of hydrogen gas is absorbed to form stable hydride. B metal cannot form stable hydrides, but hydrogen can easily move within them. In other words, metal A controls the amount of hydrogen absorbed, while metal B controls the reversibility of absorbing and releasing hydrogen. Nickel metal hydride batteries have certain advantages in the market. They have the characteristics of long cycle life, no memory effect, no pollution, high power, high density, and fast charging and discharging. They are also called green batteries and their performance indicators are far greater. For common nickel-cadmium batteries, hydrogen storage alloys can be divided into AB5 type, AB2 type, AB type, solid solution type, etc. according to the crystal structure of the alloy. Among them, the AB5 type alloy mainly uses rare earth metals. AB5 type hydrogen storage alloy is mainly composed of copper, lanthanum and nickel, with a small amount of aluminum, manganese, cobalt, etc. added. Not all hydrogen storage alloys can be used as negative electrode materials for nickel-metal hydride batteries. According to data, Japan's production of nickel metal hydride batteries mainly uses rare earth metals and mixed rare earth metals as negative electrodes. The batteries it produces account for more than 90% of the world's battery production. The United States mainly uses titanium-silver-based alloys as negative electrodes. The batteries account for about 5% of the world's production. The same thing between nickel metal hydride batteries and nickel-cadmium batteries is the same voltage. The difference is that the self-discharge rate is approx. Other performance indicators range from high to low, some are higher than nickel-cadmium batteries, and some are lower than lithium-ion batteries. Judging from the entire battery data, the country is currently vigorously promoting power batteries such as lithium batteries, nickel-hydrogen batteries, and new structure lead-acid batteries, and gradually reducing the consumption of lead, mercury, and cadmium in the battery industry. Under the development of the same industry, only Only in terms of technology can we break through the barrier. While accelerating the pace of development in the nickel-metal hydride battery manufacturing process, we must ensure that product performance meets design and technical requirements in order to achieve better and beneficial development.
