Korean scientists have developed a lifepo4 18650 battery that allows electric vehicles to travel 700 kilometers

　　Silver manganate nanosheets could allow scientists to create safer, more energy-efficient aluminum-air batteries at a lower cost. According to foreign media reports, researchers at the Ulsan National Institute of Science and Technology in South Korea have used this new type of catalyst to develop an aluminum-air battery that can solve the problems of current electric vehicle (EV) battery technology. Frequently Asked Questions, allowing electric vehicle owners to have a longer range, replaceable battery pack without the need for slow charging.

　　Compared with existing lithium-ion batteries, this new battery has higher energy density, lower cost, better cycle life, and higher safety. Additionally, it is lightweight and poses little risk of fire or explosion. Aluminum-air batteries are primary batteries and cannot be charged using conventional methods. When applied to electric vehicles, such batteries only need to replace aluminum plates and electrolytes to generate electricity. For the same weight of aluminum and gasoline, the actual energy density of aluminum is higher than that of gasoline.

　　Professor Jaephil Cho said in a statement: "The energy density of gasoline is 1,700Wh/kg. With replaceable electrolyte and aluminum plates, an aluminum-air battery has an energy density of up to 2,500Wh/kg. This means that using 1 kilogram of aluminum, we can produce a battery that can enable an electric car to travel 700 kilometers."

　　Compared with traditional aluminum-air batteries, the research team's aluminum-air battery has a discharge capacity that is 17 times higher. Similar to how other metal-air batteries operate, this battery generates electricity by reacting oxygen in the air with aluminum. Although aluminum-air batteries have one of the highest energy densities of all batteries, they are not widely used due to the high anode cost and by-products produced when using traditional electrolytes.

　　To overcome this obstacle, researchers have developed a battery that mitigates side effects in battery cells in which electrolyte is continuously circulated. The researchers prepared silver nanoparticle seed manganese oxide silver nanosheet structures for oxygen reduction reactions. The battery's increased lifespan and energy density will help make more electric vehicles more popular, and vehicles equipped with the battery will have a longer range, be lighter, and won't explode.
