Large-capacity solid-state power lithium battery put into production in Fujian

Fujian Province's 2018 key project, the first domestic and international production of 640GWh of single high-capacity solid-state polymer-powered lithium-ion battery project invested and built by the Fujian Provincial Tendering and Purchasing Group was officially put into operation. This project is the result of the 863 Torch Program of the Ministry of Science and Technology of the 14th “6·18” successfully completed by the Fujian Provincial Tendering and Purchasing Group in 2016, and the establishment of Fujian Judian New Energy Co., Ltd. in Nanping City to implement the industrialization project. The power lithium-ion battery produced by the project has passed the authoritative inspection and testing recently. Not only the various indicators meet the requirements of relevant national standards, but also the energy density is in the leading position in the industry. The 10.5-meter pure electric bus assembled by the battery was last month. During the test, a single charge can safely run more than 410 kilometers. New energy vehicle manufacturers such as Xinfuda, Jinlong and Zhongzhi have reached cooperation intentions with the project after in-depth investigation.

Chen Wu, secretary of the Party Committee and Chairman of the Fujian Provincial Tendering and Purchasing Group, delivered a speech.

On the same day, the special matchmaking event of the “6·18” project jointly sponsored by the Fujian Provincial Tendering and Purchasing Group and the Nanping Municipal People’s Government – “The Large Capacity Solid State lithium battery Seminar and the Fujian Judian (Phase I) Project Launching Ceremony” was held in Wuyi. The new district is held. It is understood that Fuju Monomer large-capacity solid-state polymer-powered lithium-ion battery has high safety and economy, and its battery cell is large and its energy density is high. The energy density reaches 165 watt-hours per kilogram, and the energy density of the battery pack and system reaches 140 watt-hours per kilogram. One battery has a nominal capacity of 500 amps, which is equivalent to 1.6 kWh. A 12-meter-long bus carries 270-degree power, using only 168 batteries, while a traditional small battery requires 30,000 batteries. The simple structure and series mode of Fuju battery also greatly enhance the safety of the vehicle. Because the battery modules are all creatively combined in series mode, the working status of each battery can be monitored in real time during operation, and the battery can be prevented in advance. The extreme conditions created ensure safety. In addition, the battery internal resistance is low, only 0.35 milliohms, which is one percent of the traditional battery. During use, the temperature itself will not exceed the ambient temperature of 5 degrees Celsius, no additional cooling system, safe and power saving.

During the conference, China Hi-Tech (600730, shares) Technology Industrialization Research Association New Energy Expert Working Committee and Zhonggao Jiechuang (Beijing) Applied Technology Research Institute organized a large-capacity solid-state polymer power lithium battery and fully automatic for Fujian Judian The production line was evaluated technically. China Vice-President of the High-Tech Industrialization Research Association, Wang Zhiguo, former vice chairman of the National Federation of Industry and Commerce, Chen Qingquan, academician of the Chinese Academy of Engineering, Chen Yong, chief engineer of the China Ship Research Institute, and other 17 well-known technology management, electric vehicles, new energy batteries, systems, etc. Experts and scholars from the field formed an evaluation committee to observe the whole process of production process and process tempo, listened to the technical summary report of the project completion unit, and conducted on-site inquiry and discussion.

On behalf of the academic evaluation report of the academician Qingquan Chen, the expert group pointed out that the automatic large-scale production line of the project is reasonable in design, the numerical control capability of the equipment is stable, the processes are synchronized and smooth, the MES system is monitored online in real time, and the quality is controllable. The localization rate of equipment reaches 85%, and the degree of automation innovation is high. The large-capacity solid-state polymer power lithium battery and fully automatic large-scale production line have a number of independent intellectual property rights, which is the first in China and has an international leading level in the same capacity production line.

In addition, Hengkuan Ji, Distinguished Vice Chairman of China High-Tech Chemical Industrialization Research Association, gave a keynote speech entitled "Development Status and Trends of New Energy Vehicles and power battery Industry". He pointed out that China and the global new energy automobile industry are booming. In 2017, the cumulative sales volume of new energy vehicles in China was 777,000. It is estimated that the sales of new energy vehicles will exceed 1 million in 2018. The breakthrough of battery core technology is a necessary condition for the sustainable development of new energy vehicles, and Fujian Judian's new energy battery is a breakthrough in the core technology of solid-state lithium battery. The production of solid-state power battery will certainly provide a powerful "new energy vehicle". The heart" has made significant contributions to the sustainable development of new energy vehicles in China.

It is reported that the Fujian Provincial Tendering and Purchasing Group is the provincial governing enterprise of Fujian Province. It is the top-ranking and most powerful technical consulting service company and project management professional institution in Fujian Province. It is also the docking and service organization for scientific and technological achievements projects determined by the Fujian Provincial Government. In recent years, on the basis of the main business of bigger and stronger technical consultation, the Group relies on the “6·18” Straits Project Achievements Fair as a technological innovation platform to vigorously cultivate new main businesses based on power batteries.

Chen Wu, Chairman of the Fujian Provincial Tendering and Purchasing Group, said at the meeting that the Group will continue to rely on the “6·18” platform for docking related projects around the high-capacity solid-state polymer-powered lithium-ion battery technology, and will do it in the new energy lithium-ion battery industry more contributions. At present, the group has successively controlled or participated in Hebei Shenzhou Judian New Energy Technology Development Co., Ltd., Xucheng (Fujian) Technology Co., Ltd. and other enterprises, and reached a preliminary agreement with Xuzhou Airport Economic Development Zone, which will set up Jiangsu in Xuzhou Judian New Energy Co., Ltd.

At the press conference, China Automotive Industry Engineering Co., Ltd., China Machinery Industry Construction Group Co., Ltd., Zhongzhi New Energy Automobile Co., Ltd., Fujian Nachuan Pipe Technology Co., Ltd., Zhongrong Guotou Real Estate Group and other units on the new energy vehicle power on the battery cooperation, large-capacity solid-state power battery procurement and other aspects signed nine cooperation agreements with the Fujian Provincial Tendering and Purchasing Group.
