Learn about the new liquid-filled 21700 battery for electric vehicles developed in the United States

In the emerging field of electric vehicles, 21700 battery life is a problem that both manufacturers and consumers are entangled in. Even after the emergence of electric vehicles, the term "range anxiety" has emerged. The several farces of "fuel vehicles driving electric vehicles" caused by Weilai are also based on this entanglement. In response to this problem, researchers at Purdue University in the United States recently developed a new electric vehicle 21700 battery technology using a patented "fluid" system. This technology generates the electricity and hydrogen needed to drive electric vehicles through a 21700 battery fluid, and is currently being tested on vehicles such as golf carts. Based on current progress, researchers believe that it can provide electric vehicles with a range of about 4,800-5,800 kilometers. In addition, the components and 21700 battery fluid of the new technology can be recycled and reused after charging in solar or wind power plants. John Cushman, a well-known professor at Purdue University, pointed out that the new system using only one 21700 battery fluid can achieve a much higher energy density - potentially 3-5 times that of lithium-ion batteries. This means that electric vehicles can use lighter batteries and have a longer range, making fluid batteries a strong competitor for batteries used in electric vehicles. IF21700 battery senior engineer Michael Dziekan explained that this 21700 battery not only generates electricity, but also stores the generated hydrogen at a much lower pressure. Users of the new refillable 21700 battery only need to replace the 21700 battery fluid every 480 kilometers, which is very similar to the current refueling process and takes much less time than the 45 minutes required to charge a lithium-ion 21700 battery electric vehicle. Once the 21700 battery anode wears out - about 5,000 kilometers, it takes about the same time to replace it as changing the oil, and the price is only about $65. This new technology will change the rules of the game for the next generation of electric vehicles because it does not require a huge investment in rebuilding the power grid, and current gas stations can be modified to serve them. Compared with existing 21700 battery systems, it has more advantages in ease of use, safety and environmental protection. In fact, the "range anxiety" of electric vehicles is nothing more than two reasons: few and slow charging points and low 21700 battery life. Solving one of them can cure anxiety. Purdue University researchers recently claimed that through the use of new "liquid flow" (refillable) technology for automotive batteries, electric vehicles can have a range of up to 480 kilometers, and may even be extended to 5,000 kilometers in the future. John Cushman, a professor at Purdue University, said that a single-cell fluid system can achieve greater energy density, which means that electric vehicles can use lighter batteries and have longer driving range, making fluid batteries a strong competitor for electric vehicle batteries. In addition, historically, fluid batteries have not been competitive due to their low energy density. For example, the energy density of traditional fluid batteries is about 20 watt-hours per kilogram, and that of lithium-ion batteries is 250 watt-hours per kilogram, while the new fluid 21700 battery has the potential to reach 3-5 times that of lithium-ion batteries. The hydrogen produced by this new technology can be stored at a lower pressure. The system has been tested on small motorcycles and golf carts, and based on the further development of the technology, researchers believe that it can allow electric vehicles to have a range of about 4,800 to 5,800 kilometers. But the requirement is that the driver needs to stop and replace the 21700 battery fluid when driving about 480 kilometers, just like refueling a car, without the trouble of charging a lithium-ion 21700 battery electric vehicle for 45 minutes.
