The new `refillable` technology for vehicle batteries provides electric vehicles with a cruising range of approximately 4800-5800 kilometers

In the field of electric vehicles, battery life is a problem that manufacturers and consumers are entangled with, and even the word "mileage anxiety" has appeared. Several farce of "fuel vehicles with electric vehicles" led by Weilai Automobile is also based on this entanglement.



In response to this problem, researchers from Purdue University in the United States recently developed a new electric vehicle battery technology using a patented "fluid" system. This technology uses a battery liquid to generate electricity and hydrogen necessary to drive electric vehicles. , Is currently being detected on vehicles such as golf carts.



Based on current progress, researchers believe that it can provide electric vehicles with a cruising range of about 4800-5800 kilometers. In addition, the new technology components and battery fluid 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 battery fluid can achieve a much higher energy density-with the potential to reach 3-5 times that of lithium-ion batteries. This means that electric vehicles can use lighter batteries and have a longer cruising range, making fluid batteries a strong competitor for batteries for electric vehicles.



IFbattery senior engineer Michael Dziekan explained that this battery not only generates electricity, but also stores the generated hydrogen at a much lower pressure.



New rechargeable battery users only need to replace the battery fluid every 480 kilometers. The whole process is very similar to the current refueling, and the time required is much shorter than the 45 minutes required to charge a lithium-ion battery electric vehicle.



Once the anode of the battery wears out-about 5,000 kilometers, the time to replace it is about the same as the oil replacement, and the price is only about $65.



This new technology will change the game rules of the next generation of electric vehicles, because it does not require huge sums of money to rebuild the power grid, and the current gas stations can be modified to serve them. Compared with the existing battery system, it has more advantages in terms of ease of use, safety and environmental protection.



In fact, there are two reasons for the "mileage anxiety" of electric vehicles: there are few and slow charging points, and the battery life is low. One of the treatments can cure anxiety.



Researchers from Purdue University in the United States recently claimed that by using a new type of `refillable` technology for vehicle batteries, the range of electric vehicles can reach 480 kilometers, and is even expected to be extended to 5,000 kilometers in the future.



Purdue University professor John Cushman said that the single battery liquid system can achieve greater energy density, which means that electric vehicles can use lighter batteries and have a longer cruising range, making fluid batteries a strong competition for batteries for electric vehicles. By.



In addition, fluid batteries have historically been uncompetitive due to low energy density. For example, traditional fluid batteries have an energy density of about 20 watt-hours per kilogram, and lithium-ion batteries have an energy density of 250 watt-hours per kilogram. New fluid batteries have the potential to reach 3-5 times that of lithium-ion batteries.



The hydrogen generated by this new technology can be stored at a lower pressure. At present, the system has been detected on scooters and golf carts. Based on the technology being further developed, researchers believe that it can allow electric vehicles to reach a cruising range of about 4800 to 5800 kilometers. But the requirement is that the driver should stop and replace the battery fluid when driving to about 480 kilometers, just like refueling a car, without the same trouble as charging a lithium-ion battery electric car for 45 minutes.
