Restarting the phosphate steel battery is a “regression” of technology or a “letting Philippines Sugar daddy app step” of capital?

In the early days of the new power car entering the market, the most obvious difference between imported and independent pure electric vehicles is continuous flights. Between the technical and capital issues of Sugar baby, the independent brand has widely used phosphate steel electrostatic battery. The 150-kilometer marking continued flight that year, coupled with the reduced low temperature and heavy weight, and the difficulty in charging network, the late-stage owner who dared to choose to buy pure electric vehicles was the absolute “brave”.

At that time, a complaint from a taxi driver in the suburbs of Beijing made the memory of “E-Car Driving”Sugar daddy” daddy deep, “Just like this hot day, you can run 120 kilometers. If you don’t open air, you can only run 60 kilometers in winter. No one can do that.” Because of this, even if the policy and supplementary support are strong, the pure electric car model is still unanswered. The Tesla Model S, which has a fuel index and a price of over one million, has become popular for high-sustainability and high-profile preparations, and has once become a “red man” in the eyes of parallel imported and used car dealers.

After that, in order to break through the continuous range, the independent brand switched its attention to the ternary steel battery. The real protector of the phosphate steel bar, Biadi and Ten, also eventually turned against the ternary steel bar battery. According to relevant data, the number of ternary steel batteries in 2016 was 6.3GWh, with a market share of 22.6%; by 2019, the number of ternary steel batteries reached 38.5GWh, and the market share also climbed to 61.7%. However, just in the phosphate ironSugar babAs the market share of yGalaxy has been declining year by year, Biadi and Tesla have successively announced that they will reboot the phosphate steel battery through the “blade battery” technology and use “unscaling” batteries.

Is the purpose of the difficult mark wrong? Phosphate steel is making a comeback

“Hey, that’s about sooner or later.” Zhengju patted the child beside him, “

As early as 2018, Tesla Mask was Sugar baby said that it is necessary to achieve “unelastic” battery, and recently it was reported that Tesla and Ningde are conducting a trade discussion on “unelastic” battery technology. Then Biadi showed the latest blade battery and showed that Biadi Han EV equipped with a new battery will soon receive market tests.

First first study—it has been often criticized. To explain the “love, hatred and hatred” between phosphate steel batteries and ternary steel batteries, the continuous operation has always been the basic element of the pure electric vehicle model. However, due to the space of the power battery layout, simple stacking batteries do not guarantee href=”https://philippines-sugar.net/”>Sugar daddy cannot solve the problem completely, so the energy density of the battery has become the purpose of breaking the mark. Coupled with the inclination of the domestic supplement policy, the long-term flight, high-density #marriage first and then fall in love, the warm and cool little sweet article has become the purpose of car companies’ technology relying on the mark, and the three-yuan steel battery once became the focus of new cars.

In fact, the biggest difference between phosphate steel and ternary steel batteries lies in the differences in positive data. The positive material of phosphate steel batteries is phosphate steel, and ternary steel batteries use piAluminum or aluminum flake. The advantage of ternary steel batteries lies in their high energy density, and their disadvantages lies in their capital and safety concerns. Today, mainstream manufacturers have used technical skills to add battery active temperature control system to control heat and reduce risk control, but the original data and capital problem cannot be solved through technical skills.

According to data research by the real steel, as of the end of 2019, the single price of domestic ternary steel battery packs was 1.05 yuan/Wh; the single price of phosphate steel battery packs was 0.8 yuan/Wh. Therefore, under the situation of a sharp decline in supplementation, phosphate steel batteries are being valued from the head.

Biadi’s “blade” plans to break the three-yuan steel sealing lock

With the domestic passenger car widely equipped with three-yuan steel batteries, phosphate steel batteries still account for nearly 40% of the market share. The important contribution lies in the high commercial vehicle field for safety. Although Biadi has cooperated with the ternary battery of passenger cars, it has not lost its advantages in the commercial vehicle field.

Under the condition that the energy density of the phosphate steel battery has not been broken, Biadi has improved the battery structure and battery pack design. The blade battery adopts long strips and is arranged side by side inside the power battery pack. The tight slab structure replaces the original stitching and beam structures inside the power battery pack, and reduces the unnecessary module shell structure. It can effectively reduce the internal space application rate of the battery pack, thereby increasing the overall battery pack energy density.

At the same time, the blade battery can not only be directly packaged into a power battery module, but also add temperature search keywords: Protagonist: Ye Qiuguan|Supporting role: Xie Xidu governance system connects to the touch area, improves cooling or heating functions, and reduces the additional consumption of the temperature control system. At the same time, the different car models only need to change the blade battery length to adapt to the different car models, which enhances the battery adaptability of the blade.

The three-metallic electrostatic battery has certainly strong expansion ability in terms of energy density, but the high density brought by high activity also has high risks. After entering 2019, the spontaneous combustion caused by heat loss control has increased significantly, and safety problems have gradually become Focus. Recently, Biadi has been questioning Ping An issue, showing the differences in the ternary steel battery, phosphate steel block battery, and Biadi blade battery after being stabbed.

When the steel pin pierces the core of the power battery and causes the core to short circuit, the ternary steel battery has undergone a dramatic temperature change, EscortThe temperature agility exceeds 50Sugar daddy0℃, and extreme heat loss and control burning occurs. Although the traditional steel phosphate battery does not have an open flame after being pierced, it has a white smoke and the temperature reaches 200℃-40Pinay escort0This knowledge competition will combine questions and discussions. Participant-Jiabin℃ has a chance to rest. During her nap, she had a dream. . Blade Electric Manila escort poolEscort After being penetrated, there is no open flame or smoke. At the same time, the battery general temperature is only 30℃-60℃. Euro Minggao, an academician of the Chinese Academy of Sciences, believes: “This is important thanks to the unique design characteristics of the blade battery, which makes it produce less heat and dissipate quickly when short-circuited. “In addition, Biadi internal engineers revealed to “E-Car Transfer”: “By 2021, pure electric and plug-in hybrid models will popularize the application of blade batteries. ”
