Fujian realizes new energy battery breakthrough, large-capacity solid-state power lithium battery will be put into production

On the afternoon of March 18, the first phase of the first-generation single-capacity solid-state polymer-powered lithium-ion battery project, which was invested and built by the Fujian Provincial Bidding and Purchasing Group, was officially put into operation. As a key project in Fujian Province in 2018, this power lithium-ion battery has recently passed the authoritative inspection. The 10.5-meter pure electric bus assembled by the battery was tested safely for more than 410 kilometers on a single charge.

According to experts at the conference, the core of the new energy electric vehicle is the battery. The Fuju monomer high-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, the battery pack and system energy density is more than 140 watts per kilogram, and the nominal capacity of a battery is 500 ampere, equivalent to 1.6 kWh, that is, a 12-meter-long bus. It is equipped with 270-degree battery and only needs 168 batteries, while the traditional small battery requires 30,000 batteries. The simple structure and series mode of the battery also greatly improve the safety of the vehicle. Because the battery modules are all creatively combined in series mode, the working state of each battery can be monitored in real time during work operation, and the battery generation can be prevented in advance. Extreme conditions to ensure safety. In addition, the battery internal resistance is low, only 0.35 mΩ, 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.

It is reported that the Fujian Provincial Tendering and Purchasing Group successfully docked the achievements of the 863 Torch Plan of the Ministry of Science and Technology in 2016 – the large-capacity solid-state polymer-powered lithium-ion battery project, and established Fujian Judian New Energy Co., Ltd. in Nanping to implement project industrialization. . The Fujian Provincial Government has included the project in the 2017 provincial preparatory key project, and the provincial key projects in 2018 have been supported. New energy vehicle manufacturers such as Xinfuda, Jinlong and Zhongzhi have reached an agreement with the project after in-depth investigation and investigation.

Chen Wu, chairman of the Party Committee of Fujian Provincial Tendering and Purchasing Group, said at the meeting that the group company will continue to rely on the “6 ? 18” platform for docking related projects around the large-capacity solid-state polymer-powered lithium-ion battery technology, in the new energy lithium-ion battery. Do more contributions in the industry. At present, the group has successively controlled 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, and Jiangsu Judian New Energy Co., Ltd. will be established in Xuzhou.

At the launching ceremony of the project, China Automotive Industry Engineering Co., Ltd., China National 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 also Automobile power battery supporting cooperation, large-capacity solid-state power battery procurement and other aspects signed a number of cooperation agreements with the provincial tender procurement group.
