Under the support of the “12th Five-Year Plan†National 863 Program, the “ High-energy Lithium-ion Battery System and Battery Pack Technology Development†project has made significant progress. Yesterday, according to the website of the Ministry of Science and Technology, the project research and development product single cell battery energy density reached 138.6 watt-hours / kg, power density reached 915.6 watts / kg, after 1200 cycles of capacity retention rate of 94.1%, the results have begun to be applied to the bulk The 50 ampere-hour power battery is produced.
Among them, the 38.4 volt/50 ampere-hour battery module for electric vehicles has an energy density of 121 watt-hours/kilogram and a power density of 800 watts/kilogram; the 345.6 volts/50 ampere-hour battery system has been applied to Chery's small pure electric cars and Austrian New pure electric sanitation vehicle.
According to the website of the Ministry of Science and Technology, the project has also made important progress in domestic production and manufacturing equipment. It has developed a fully automated automatic feeding system and battery-forming fixtures that can automatically install batteries, greatly improving battery consistency. The core matching rate is greater than 95%, which is an important step in meeting the high requirements for automotive applications.
In fact, under the background of rapid progress in lithium battery technology, it will drive the rapid development of the lithium battery industry. According to predictions from world-renowned consulting company Frost Sullivan, the future prospects for lithium batteries are considerable. By 2015, China's lithium-ion battery production capacity will reach 3.9 billion amp-hours. By then, China's electric vehicle demand will be around 120,000, and lithium batteries will need to be consumed. 900 million hrs. The lithium battery industry entered the era of 100 billion.
