LR936 battery.India develops metal air-powered battery

　　According to foreign media reports, Log9Materials, a start-up company founded by several graduates of the Indian Institute of Technology (IIT) in Bangalore, India, is committed to solving the "range anxiety" problem of electric vehicles and has launched a metal-air battery. This battery technology can increase battery energy density tenfold, allowing electric vehicles to have a cruising range of more than 1,000km. Akshay Singhal, founder of Log9Materials, said that the company mainly develops graphene nanotechnology, aiming to innovate and develop "graphene" materials for end users and achieve commercial applications. Log9 has used this technology to launch a metal-air battery. The metal-air battery is powered by water, air and metal. It is a primary energy production technology very similar to a fuel cell. The use of graphene materials can make the battery more commercially viable. sex and economy. Traditional lithium-ion batteries store energy without generating energy. If we take electric vehicles (EVs) as an example, an EV has a range of 100 to 150 kilometers and takes 5 to 6 hours to charge. However, metal-air battery technology can increase battery energy density tenfold. After replacing the battery metal within a few minutes, the cruising range of electric vehicles can exceed 1,000km. Singhal explained: “The energy generated by this battery technology is completely clean, has zero emissions, is equipped with sustainable raw materials, and is a truly environmentally friendly technology. Moreover, the metals used to produce energy in the battery can also be recycled. In addition, users every 200 kilometers The battery can be rehydrated without charging it. The water and aluminum metal can keep the car's lithium-ion battery for another 200 kilometers. But when the electric vehicle's range reaches 1,000 kilometers, the user must replace the metal (aluminum)." The company currently Battery prototypes are being designed and tested on the Mahindra e20 model, because the Mahindra e20 model is currently the only "proven electric vehicle model" in the Indian market. However, the metal casing of the battery is very bulky and takes up the entire back seat of the car, and the company is currently working to reduce its size, with plans to reduce its size by a third within the next year. Once the company successfully shrinks the size of the metal battery compartment, the product could be used in many other electric vehicle models.
