How to lay out the new battery technology?

December 16, also known as "Wei Lai Day", this day, Wei Lai ES8 listed at the Beijing Wukesong Sports Center.

The 70-kilowatt-hour liquid-cooled thermostat battery pack carried by this high-profile "China Tesla" uses a high-energy density VDA vehicle level square shell core with a cycle life of up to 2,000 times and a vehicle wind resistance coefficient as low as 0.29. The maximum endurance of 60 km/h exceeds 500 kilometers. NEDC comprehensive working conditions 355 kilometers.

It is worth mentioning that in the power battery, Ulai not only chose the most advanced lithium electric unicorn in the Ningde era as a core supplier, but also actively deployed new battery technology. There are only four public solid-state battery patents.

Solid state batteries, simply speaking, use solid state electrolytes to increase the voltage platform and further increase the battery energy density; On the other hand, in the fixation reaction, gas emissions can be reduced and the safety performance of lithium batteries can be improved. Among the many new battery technologies, solid-state batteries are known as the most reliable next-generation lithium technology.

As the most popular new car building force and the new battery technology that is closest to industrialization, it is easy to form the view that "emerging car companies should choose new battery technology". But in fact, not all of the new car makers have spent as much energy betting on the next generation of battery technology.

Industry insiders pointed out that for car companies, solid state batteries and other new battery technology is a double-edged sword. On the one hand, the new battery technology has many performance advantages such as higher energy density, and the preemptive layout may become the first person to eat crabs; On the other hand, the high research and development costs of new battery technology and the long effective cycle have not paid off for new car companies. In addition, the industrialization of forward-looking technology also has extremely high risks.

Therefore, for the new battery technology, the choice of newly built car forces is actually conservative. Even if it is involved, it is mainly based on temptation, and more is on the sidelines.

Dr Xuhuanxin, chief operating officer of Weimar, said that the company's requirements for battery technology are actually very simple, one is to increase energy density, and the other is to ensure safety performance. Battery technology is a relatively open thing. In the end, it is not yet certain. Weimar's cooperation with some companies engaged in forward-looking battery technology is more of an exploratory nature.

In fact, in October, it was reported that Weimar had made an alliance with huineng and signed a memorandum of cooperation. It is expected that in the first quarter of 2018, the world's first new energy electric vehicle using a new generation of lithium ceramic batteries will be jointly produced and unveiled at the Beijing Motor Show in April 2018. At the same time, it accelerated cooperation with Huineng Technology and jointly constructed a production line of 5GWh production capacity in 2018. It is expected to be completed by the end of 2019 and put into production.

It is reported that Huineng Technology is a supplier of lithium battery dim sum in Taiwan. Its chairman, Yangsinan, said that Huineng Technology has developed a new generation of lithium ceramic batteries from the key test standards of electric vehicle batteries: energy density, charging time, service life, and safety, with fast charging speed, strong safety, and ultra-high energy density. Excellent high and low temperature operation performance and other characteristics, And can greatly reduce costs. The 2020 target is 1000W/L, which is 1.4 to 1.5 times that of similar products on the market.

For the cooperation with Huineng Technology, Xuhuanxin said that he was not aware of it. Even if there was cooperation, it was only based on exploratory cooperation. For the time being, battery technology is still very open, and it is hard to say who will dominate in the future. Weimar will explore with forward-looking battery companies but will not bind itself to a particular technology. At present, Weimar's main energy is still focused on the technologies currently available.

According to the Weimar car plan, the first batch of Weimar cars will be produced in small quantities at the Wenzhou factory early next year, and will be officially mass-produced in the second half of the year. At that time, Weimar will use the facts to respond to the choice of battery technology.

In addition, Baoxudong, deputy general manager of Yundu New Energy Vehicle Marketing Center, also believes that premature deployment of emerging battery technology is not a good choice.

At the end of August, Yundu New Energy Automobile(hereinafter referred to as Yundu)'s first pure electric SUV, Yundu π 1, was officially launched at the assembly plant in Yundu. In terms of power battery selection, Yundu Automobile cooperated with Bic Battery to use a 1,8650 battery with high energy density and lightweight design, which is divided into an urban version and an intercity version. The comprehensive operating range is 150km and 250km, respectively.

For the new battery technology, Baoxudong believes that blindly pursuing new technologies is actually not worth the loss. Therefore, cloudiness will find a balance between quality, stability, performance, and cost according to the mainstream technology in the market to promote the current product. At the same time, it will also use power batteries such as lightweight, heat dissipation, PACK design, etc.. Practical research and development, For particularly advanced technologies, it will not participate in research for the time being because it means high investment and low returns.

Mr Baoxudong said the much-touted new battery technology, or advanced driverless technology, was more of an eye attraction and did not help the market much in the short term. For now, the cloud will focus on the market demand within two years to invest energy and allocate funds. Of course, cloudiness will watch the development of new technologies in real time and choose to cut in when appropriate.
