China's fuel car industry has been lagging behind other countries, as environmental protection is becoming more and more important, in recent years, countries around the world are also paying more and more attention to new energy vehicles, China's new energy vehicle industry in recent years has been rapid development, both production and sales are world leading, so far, China is the country with the most research and development and subsidies for new energy models, China is also the country with the most new energy vehicle brands, whether it can bend the road The development of new energy vehicles is particularly important to overtake the car. However, the development of new energy vehicles has encountered an unprecedented bottleneck due to the technical problems of lithium batteries. Higher density and faster charging is an urgent need to solve.
Today, the vast majority of new energy models equipped with lithium batteries for ternary lithium and lithium iron phosphate, although the ternary lithium battery has a higher energy density, with a longer range and low-temperature resistance, but relatively poor stability. And service life is also a big problem, and lithium iron phosphate can precisely meet the market demand in these two areas, but the low-temperature performance and energy density of retail lithium iron batteries is also a bigger problem, BYD launched the blade battery is also a kind of lithium iron phosphate batteries. This is also a technological innovation. Let the development of China's new energy vehicle industry to see the new dawn.
Now, the range of 1000Km is a very high ridge, due to the energy density of lithium batteries, to reach 1000Km range of new energy vehicles will inevitably have a larger volume and weight, for the family car is not desirable. And higher prices and the more expensive cost of future battery replacement is less acceptable to the market. The popularity of charging piles and slow charging speed is also a big reason to curb the development of the new energy vehicle industry.
Toyota recently revealed a new technology that may be able to measure the dilemma facing new energy vehicles, Tian and Kyoto University are developing the latest battery technology - the fluoride-ion battery (Fluoride-ion), this technology under the battery compared to the traditional ternary lithium battery has a huge energy density advantage, is seven times the energy density of traditional batteries, according to the current average volume of new energy vehicle battery calculation. According to the current average volume of new energy vehicle batteries, the range of models equipped with fluoride ion battery pack can reach 1000 km, which will completely solve the problem of new energy vehicle mileage anxiety.
Although this technology has been studied by many car companies before, but the fluorine ion battery activity is too high will lead to higher battery operating temperature, resulting in battery expansion, there are certain safety risks, so it was put on the shelf. But Toyota seems to have found a solution, Toyota by using cobalt, nickel, copper alloy made of electrodes to prevent its expansion, can also reduce the fluorine ion activity, to protect the safety factor.
According to Toyota's planning, this battery can be mass-produced in 2025 at the earliest, when Toyota's models will have pure electric version, and fluoride ion battery pack is Toyota's pure electric models, with super high range to solve the problem of mileage anxiety, thus giving Toyota an advantage in the field of pure tram. In addition, according to the cooperation agreement between BYD and Toyota, BYD may also share this battery technology in the future, so that BYD's models also have a super range.
I hope Toyota's fluorine ion battery pack can be marketed as soon as possible, which will not only enhance Toyota's competitiveness in China, but also let more Chinese car companies see the technology gap, so that they can make great efforts to develop battery technology and let Chinese batteries go to the world.
