[China Aluminum Network] Aluminum air battery is a type of metal air battery, this battery is known as a "only plus water, you can cruising 3000Km" Monster battery, can be regarded as the residue of the existing batteries on the market! Is this really true? Next, we will analyze the aluminum air battery technology. Aluminum air battery is a type of metal air battery, this battery is called a "only plus water, you can cruising 3000Km" Monster battery, can be used to slag the existing batteries on the market! Is this really true? Next, we will analyze the aluminum air battery technology. Analysis of 3000km Aluminum Air Battery Technology 1, aluminum air battery principle The chemical reaction of aluminum air batteries is similar to that of zinc air batteries. Aluminum air batteries use high-purity aluminum Al (containing 99.99% aluminum) as the anode, oxygen as the cathode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) as the electrolyte. . Aluminum ingests oxygen in the air and generates a chemical reaction when the battery is discharged, and aluminum and oxygen convert to aluminum oxide. 2. Advantages and disadvantages of aluminum air battery The advantages of aluminum air batteries are mainly reflected in the following aspects: 1 than the energy, aluminum air battery theoretical specific energy up to 8100Wh/kg; 2 Lighter weight, the same energy of the aluminum air battery is only 12% of the lead-acid battery quality; 3 non-toxic danger, can be recycled and used; 4 Aluminum is rich in raw materials. The disadvantages of aluminum air batteries are also obvious: 1 is a chemical reaction device that releases electrical energy. It cannot be recharged repeatedly. Aluminum electrodes need to be replaced to continue working. 2Although aluminum air batteries contain high specific energy, their specific power is lower; 3 The charging and discharging speeds are relatively slow, the voltage lags behind, and the self-discharge rate is large; 4 A thermal management system is needed to prevent overheating of the aluminum-air battery during operation. The advantages and disadvantages of aluminum air batteries compared to today's lithium-ion batteries are shown in the table below. 3, a brief history of aluminum air battery development Al-air batteries have been available for more than 70 years now. Now we simply summarize the "evolution" of such batteries at home and abroad. 4. Current Status of Aluminum Air Battery Industrialization at Home and Abroad In 2015, Alcoa and Israel's Phinergy showed the world record of driving a 1600-kilometer-equipped car with a 100-kilogram heavy aluminum air battery at the Villeneuve Raceway in Montreal. Many media have made "alum air batteries. It is a report of a traditional battery killer. At present, there are three major domestic enterprises involving aluminum air batteries, namely Aerospace Technology, Yunlu Aluminum and China Power. Air Sky Technology Co., Ltd. is a high-tech enterprise specializing in aluminum air battery research and development. It is reported that Aerospace Technologies and Tianjin University have researched and solved the three major core technical problems: large passivation and self-discharge of aluminum anode discharge, low catalytic efficiency of air electrode catalysts, and high price, and the technology of “sweat†leakage of air electrode waterproof membranes. Problems, mastered the core technology of battery manufacturing with independent intellectual property rights. The aluminum air battery developed by it has the characteristics of high power density, high specific energy, long life, no pollution to the environment, safety, low cost, etc., and has developed aluminum with different power levels of 100W, 200W, 500W, 1kW, 3kW, and 5kW. Air battery module, and initially formed the industrialization pattern. On October 22, 2016, Yunluo shares a joint venture with Chuangneng to establish Yunnan Yunlua Huichuang Luneng Battery Co., Ltd. The new company will invest in the construction of a 20MW (milliwatts) aluminum air battery production line with 200,000 units/year of power supply products. The production capacity. China Power and PHINERGY have established a joint venture company and plan to promote aluminum air batteries in electric models such as buses, coaches, logistics vehicles and sports utility vehicles. In addition, the Peking University-Taizhou Metallic Fuel Cell Research Center has taken the lead in the research and development of aluminum air batteries and began to realize industrialized production. The company has cooperated with the Geely Automotive Research Institute and conducted a road test on the Geely Panda car. So far, the company is a company that can use aluminum air batteries to drive electric vehicles and has a much longer mileage than lithium batteries. On November 8, 2016, 1,000 units of aluminum air metal fuel UPS (uninterrupted power supply) of Deyang Dongshen New Energy Technology Co., Ltd. formally went offline. These aluminum-air batteries will be used for the standby power supply of the Deyang Tower base station, replacing the original diesel power generation. Machines and lead-acid batteries. It is reported that this is the first commercialization of aluminum air batteries in the country. 5, aluminum air battery prospects The development of domestic aluminum air batteries is in full swing. Does it mean that aluminum air batteries can be commercialized right away? The author believes that aluminum-air batteries must be commercialized at present and it is very difficult. At the front, key technologies did not achieve breakthroughs, and the polarization of air electrodes and the deposition of aluminum hydroxide were important obstacles to the marketization of metal-air batteries. The improvement in the performance of aluminum-air batteries encountered a major bottleneck and is still in the laboratory. stage. Second, China does not currently have the conditions for the commercialization of aluminum air batteries. Nowadays there are relatively few domestic aluminum air battery companies. These companies cannot support the entire industry chain at all. Of course, the advantages of aluminum air batteries are there. Whether it is the scary energy density, safety, or environmental protection, it has unparalleled advantages. Therefore, summing up in one sentence means that “the prospects are bright and the road is tortuousâ€. Stainless Steel Baking Cooling Rack
