Verdi Battery Sun Huajun: before 2025, the cost of power battery will drop to 0.5 yuan/Wh

ABEC 2020│The 8th Battery \"Davos\" Forum Site

Battery \"Davos\"-Battery Network News on October 27th (Chen Yu Zhang Qian, Changsha Ningxiang live photo and text)On October 27-29, the annual global battery industry event-ABEC 2020 | The 8th China (Changsha·Ningxiang) International Battery New Energy Industry Summit Forum was grandly held in Changsha Ningxiang. This forum is hosted by the ABEC (Battery \"Davos\") Organizing Committee, Zhongguancun New Battery Technology Innovation Alliance, and is exclusively co-organized by Ningxiang High-tech Zone. More than 500 people from the global battery new energy industry chain \"government, industry\" Representatives from all walks of life, including science, education, research, finance, service, and use, as well as the media attended the event. Under the background of global competition in battery new energy, they explored the upward path of independent brands and discussed the construction of the industrial healthy ecological chain.

During the same period of the forum, the 2020 Hunan (Changsha) Battery Industry Expo, sponsored by the Hunan Provincial Department of Industry and Information Technology, Hunan Provincial Department of Commerce, and Changsha Municipal People’s Government, was grandly opened with an exhibition area of ​​20,000 square meters, focusing on cutting-edge industrial products, technologies, and services. Bringing together BYD, BAIC New Energy, Chery New Energy, Lishen Battery, Vision Group, Xinwangda, Electric General, Zhongke Star City, Huabao Energy Storage, Polyfluoride, Shida Shenghua, Jin Yinhe, Han's Laser, Austrian Nearly 200 high-quality exhibitors in the battery new energy industry chain, such as Tewei and Wuxing Aluminum.

On the afternoon of the 27th, Sun Huajun, Deputy General Manager and Director of the Big Battery Development Center of Fordy Battery Co., Ltd. gave a keynote speech entitled \"Power Battery Technology Innovation and Practice\" at the forum, sharing the development of the new energy vehicle industry and power battery , Battery technology innovation, Fudi battery innovation practice, etc., battery network selected some of its wonderful views, to enjoy readers:

\"I just heard the voice of customers, the cost of power battery will reach 0.5 yuan/Wh in 2025. I think we should achieve this goal earlier. How to achieve this cost goal? The core lies in the technological innovation of power battery. \"Sun Hua Jun said in the opening remarks of his speech, \"After a lot of favorable policies and the results of the entire industry in the product and in-depth fields, starting from 2015, the entire new energy vehicle market has undergone very big changes.\"

\"This is a very important five years. In five years, we have also seen and experienced a lot of things, including very bad things, such as subsidies, fraudulent compensation, and product quality. In addition, , We have also seen fire incidents based on safety accidents, which have had a bad impact on the development of the entire new energy vehicle.\" Sun Huajun said that in the next five years or longer development, the entire new energy The car has passed the \"survival\" era, it should be the era of high-demand products pursuing high standards, high quality, high performance and low cost.

Based on the requirements of the era of high-demand products, Sun Huajun believes that in the entire power battery industry and power battery field, a series of technological innovations need to be passed, including electrochemistry, structure, manufacturing technology, safety technology, testing and evaluation technology, etc. In terms of technological innovation, we develop products that truly meet high requirements.

Among them, in terms of electrochemical innovation, Sun Huajun cited innovations in material systems such as cathode materials, anode materials, electrolytes, and diaphragms.

In terms of structural innovation, Sun Huajun listed the innovative structure of the blade battery: the blade battery breaks through the constraints of the traditional drawing/extrusion process, and the innovative process realizes the bending and butt welding technology of the ultra-long aluminum shell with a thickness of 0.3mm, which can meet the requirements of the battery cell and the entire package level. Design requirements: In terms of battery packs, the innovative use of the whole pack sandwich structure, the use of the blade cell's ultra-large aspect ratio design, the closely arranged cell design and the development of high-performance adhesives to achieve ultra-high battery pack strength and rigidity.

In terms of manufacturing technology innovation, Sun Huajun briefly introduced the innovation of manufacturing technology such as automation, online monitoring, wide-width coating, wide-width roll pressing, and wide-width lamination.

\"From the entire battery development process, we can see that all our technological innovations are not achieved overnight, including blade batteries, which are not whimsical concepts. They are based on 18 years of innovation in the field of materials and more than 10 years of structural fields. Innovations gave birth to the concept of blade batteries that we started in 2018, and we have done a lot of application development in the past year and a half, and realized the product of blade batteries. \"According to Sun Huajun, Verdi Battery is in the entire product field. , Including from mineral resources to materials, processes, batteries, BMS, modules, PACK, including recycling, innovation of the entire industry chain, each field has a corresponding R&D team, totaling more than 3,000 people.

Finally, Sun Huajun concluded that, based on technological innovation, Fordy Battery has refined six super performances that are very important for power batteries in the vehicle: safety, strength, battery life, low temperature, life and power. \"The needs of the whole vehicle are from these six aspects, and all the work we develop should focus on these six aspects\".
