The Ministry of Science and Technology website reported on June 25th that under the support of the “12th Five-Year†National 863 Program, the “High-energy Lithium-ion Battery System and Battery Pack Technology Development†project has made significant progress. The project aimed at developing high-energy lithium-ion batteries for lithium iron phosphate cathode materials, and conducted research on lithium-ion battery raw materials and battery cell design technologies.
The research and development product has a single cell battery energy density of 138.6 watt-hours/kg, a power density of 915.6 watts/kilogram, and a capacity retention rate of 94.1% after 1200 cycles. The results have been applied to 50 ampere-hour energy-type power batteries for mass production. on. Among them, the battery power density of the 38.4V/50A battery for electric vehicles reaches 121Wh/kg, and the power density reaches 800W/kg; the 345.6V/50AH battery system has been applied to Chery's small pure electric cars and the Austrian New pure electric sanitation vehicle.
The project has also made important progress in domestic production and manufacturing equipment. It has developed a fully automatic closed automatic feeding system, a battery plate automatic lamination machine, a large-capacity battery automatic injection machine, and a battery that can automatically hold the battery. Forming fixtures, and established automated lithium ion battery detection and matching production line, greatly improving the consistency of the battery, the battery core matching rate is greater than 95%, to take an important step in meeting the high requirements of automotive applications.
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced.
