(Wuhan News): recently, the company's related technical personnel in Wuhan and related battery plant experts, technicians on the future development of solid-state batteries and the use of vehicles and other topics for academic exchanges and discussions. It is reported that new energy vehicle power battery technology has a new breakthrough: solid-state batteries are widely used in 5 years, capacity doubled 10 minutes full.
Experts say: now a new battery technology breakthrough seems to be close to us, and it can almost meet our expectations new technology can meet the needs of mobile phones for several days. The safety has also been improved by increasing the mileage of electric vehicle users to more than 500 miles.
Solid-state battery technology is set to start: lithium ion batteries are a huge improvement over earlier lead-acid batteries, nickel-cadmium batteries and Ni-MH batteries. But as the latest long-range electric vehicles enter the market, such as Tesla's Model 3 and Dongfeng. Junfeng E 11K、Fengshen E 70, they need to be equipped with more than 300 kilograms of batteries.
People think that solid state battery technology is expected to make a huge leap forward in three key areas, one of which is that batteries of the same size can at least double their power supply capacity.
This is what experts call an increase in energy density. As a result, the energy density of the battery can be more than twice that of the existing battery.
That would allow carmakers to halve battery sizes with the same range of mileage requirements, or double the vehicle's range and improve performance, such as the SUV., which provides users with nearly 500km of range and has the sense of acceleration of a sports car.
"Solid-state battery technology is also possible to achieve ultra-fast charging, and charging your electric vehicle is as simple and time saving as adding fuel to a fuel-powered car." In other words, it takes only 5 to 10 minutes to recharge. On the price side, a new study by a leading foreign consultancy estimates that lithium ion batteries will drop to $70 per kilowatt-hour in seven years and that solid-state batteries will be 20 cents cheaper than lithium-ion batteries. The solid-state battery is named for its use of ceramic materials to replace liquid electrolytes in ordinary batteries.
This is another advantage because liquids in lithium-ion batteries are as flammable as gasoline, which is why aviation is banned from using them on airplanes. Defects in lithium-ion batteries have led to many accidents. Solid-state battery researchers say they are getting ready for the spring of solid-state battery use and hope that the plant will follow up ahead of schedule and make bold attempts. Battery makers, who have demonstrated the technology in the laboratory, must now ensure that solid state batteries can be produced in large quantities, and that they can be used in a specific charging environment where electric cars run daily. Solid-state batteries, of course, have some fatal flaws to overcome, and battery company experts are soberly aware of this.
Through the exchange between the two sides, they have found their own demands and concerns, deepened the understanding and understanding of the battery industry, and reached a broad consensus on the use of new technologies and materials in the future. (XiaWu)
