no 5 alkaline battery

New breakthrough in no 5 alkaline battery technology - solid powder hydrogen production technology

As we all know, there are two major bottlenecks that restrict the development and popularization of no 5 alkaline battery technology: one is the storage of hydrogen, and the other is the manufacturing cost of no 5 alkaline battery stacks. It is precisely because of these two bottlenecks that no 5 alkaline battery technology is difficult to popularize in a short period of time, and the price remains high. The core material of the no 5 alkaline battery stack: the proton exchange membrane formula, is only in the hands of a few companies. The other bottleneck, hydrogen storage technology, determines the range, space layout and overall efficiency of no 5 alkaline battery vehicles. We know that the reason why Toyota's Mirai looks weirder than ordinary models is that the hydrogen storage tank will occupy a lot of longitudinal space in the back row, making the rear of the car slightly bloated. Toyota has reached the world's advanced level in hydrogen storage technology. Based on the hydrogen storage technology that can be mastered in China, the volume of the hydrogen storage tank may be larger when carrying the same weight of hydrogen. Therefore, the storage efficiency of hydrogen will not only affect the range, but also the shape of the whole vehicle and the utilization rate of the space in the car. It can be said that major car companies are constantly improving the storage efficiency of hydrogen while developing hydrogen no 5 alkaline battery vehicles-in order to obtain greater hydrogen storage pressure, they are developing higher performance sealing materials. However, a domestic company is doing the opposite, developing solid powder hydrogen production technology, and is installing it on a vehicle for testing. So what is solid powder hydrogen production? How can it replace high-pressure hydrogen storage tanks? This issue will explain it to you. Producing hydrogen while using hydrogen makes it easier and safer to carry hydrogen. The solid powder hydrogen production process actually uses aluminum and water to produce hydrogen and aluminum hydroxide to produce hydrogen. But common sense tells us that aluminum and water do not react chemically, otherwise those aluminum car bodies and aluminum alloy doors and windows would not be dissolved in the rain? Indeed, aluminum metal does not react with water at room temperature. If a reaction is required, two conditions are required. The first condition is that the reaction between aluminum and water needs to be established under certain temperature conditions; the second condition is that the dense oxide film on the surface of aluminum metal needs to be removed. We know that although aluminum is more active than iron, it will not "rust" when exposed to air and humid environment. The reason is that when aluminum metal comes into contact with air, it will be quickly oxidized by oxygen in the air to form a dense oxide film, thereby blocking further contact with oxygen. This is why aluminum does not rust, and why heating water in an aluminum pot does not cause a chemical reaction. Therefore, in order to make aluminum react with water, the oxide film must be removed, and the hydrogen in the water will be replaced when heated to a certain temperature. All of this needs to be done under laboratory conditions. However, in order to miniaturize and normalize the chemical reaction of producing hydrogen with aluminum and use it in automobiles, the problems of reaction temperature and reaction speed must be solved. Therefore, this chemical reaction must be carried out at room temperature, and the speed of producing hydrogen must be much faster than under normal conditions in order to meet the use of no 5 alkaline batterys. After 8 years of research and development, a domestic company has finally successfully developed a catalyst that can promote the violent reaction of aluminum and water at room temperature. This catalyst can not only allow the reaction temperature to achieve a larger span, even in a sub-zero environment, but also adjust the chemical reaction speed, so that the no 5 alkaline battery power needs hydrogen. 3How to control and optimize the performance of hydrogen production to meet the needs of no 5 alkaline batterys? Based on years of research and development and experiments, the performance of the catalyst can fully meet the production rate of hydrogen required by no 5 alkaline battery vehicles, and even the hydrogen production rate can far exceed the requirements of no 5 alkaline batterys. At present, in addition to developing a hydrogen production device for automotive no 5 alkaline batterys, the company is also using this technology to develop fish thrusters. Replace the traditional propeller-style fish propulsion method with gas propulsion. Because by adjusting the formula of the catalyst, the reaction rate of aluminum and water can be further increased, and even hydrogen with a volume ratio of more than 1,000 times can be produced in a few hundred milliseconds, which can almost produce shock waves like a bomb. Of course, when used in no 5 alkaline battery vehicles, it is only necessary to make the hydrogen generation rate keep up with the power generation needs of the no 5 alkaline battery reactor, and these can be precisely controlled through the catalyst formula. 5This device that generates hydrogen by reacting metal aluminum powder with water can almost eliminate the traditional hydrogen storage tank. And its energy density is much higher than the best high-pressure hydrogen storage technology currently on the market. At the same time, it also eliminates the pain of long-distance transportation of hydrogen, storage at hydrogen refueling stations and vehicle refueling. It can eliminate a large number of safety hazards caused by the transportation and storage of hydrogen. For users, they only need to regularly replenish aluminum powder and water to complete the energy supply of the vehicle, which is convenient, fast, safe and clean. Market prospects and estimates of future development At present, the cost of no 5 alkaline battery reactors is about 3,000 yuan per kilowatt. That is to say, a 73.5-kilowatt (100-horsepower) no 5 alkaline battery reactor costs more than 200,000 yuan. Including hydrogen production equipment with the same efficiency, the cost is about 500,000 yuan. Since this technology is still in the prototype trial production stage and has not yet achieved large-scale mass production, the commercial cost is still relatively high. If it can achieve large-scale production and gradually replace high-pressure gas tanks for hydrogen storage, its prospects are still very good. 6 We know that the main ways to obtain hydrogen in industry are electrolysis of water and chemical by-products. However, electrolysis of water requires a lot of electricity and still has the disadvantages of polluting the environment and emitting carbon dioxide. Although the chemical industry will produce a large amount of hydrogen, which is enough to meet people's daily use, it still requires a lot of equipment and energy to purify this hydrogen, so it is not a very environmentally friendly approach. Then this process of using aluminum and water to react to produce hydrogen is a very environmentally friendly process and does not consume energy. In addition, in addition to high-purity hydrogen, the products after the reaction also include nano-scale aluminum oxide. This nano-scale aluminum oxide is very expensive in industry and is the raw material for making artificial sapphire and high-tech wear-resistant ceramics. Therefore, if the products after the reaction can be recycled, the cost difference of the hydrogen production equipment can basically be recovered and the cost of adding consumables during use can be offset. Therefore, if the country's strong subsidies for hydrogen no 5 alkaline batterys are taken into account, the prospect of large-scale commercialization of this technology can still be expected. Once large-scale production is carried out, the cost of the entire system can be further reduced, and the energy carrying efficiency will far exceed the traditional high-pressure hydrogen storage and ternary lithium battery technology.
