2.1 billion main funds withdrawed lithium battery concept stocks in the past three days

According to the Henan Daily, after more than a year of arduous innovation and trial and error, the Electric Power Research Institute of Henan Electric Power Company successfully designed and built the first domestic production line of 5,000 tons/year based on dry-process automatic power battery recycling, realizing the power lithium battery. Efficient, environmentally friendly recycling.

As Dr. EPRI electric province, deputy director of the State Grid Corporation of waste resource processing technology laboratory network, Guang gold is committed to "waste to treasure", digging a huge environmental and economic potential of the field of electric vehicle battery retired hidden, a research Pioneer and pathfinder for the use and recycling of ladders.

In 2010, with the support of the State Grid Corporation, Zhao Guangjin took the lead in researching the use of decommissioned batteries. To achieve interconnection and interoperability of the global energy Internet, decentralized new energy sources such as different power quality, different frequency wind energy, and photovoltaic power generation should be connected to the power grid, including peaking and frequency modulation of the power grid, and peaking and valley filling, all of which require a “reservoir”. Energy storage system. Energy storage systems are not subject to large-scale use due to high technical costs. If the decommissioned electric vehicle battery ladder is used as an energy storage system, it can not only meet the demand, but also cost one third of the same type of new battery.

In Zhao Guangjin's research, the retired battery realized two "gorgeous turns". The first time was at the Xinmijianshan Experimental Base, which built the first 100-kilowatt wind power storage microgrid demonstration project based on decommissioned batteries, and successfully verified the utilization capacity of the decommissioned batteries. The second time is the low-cost green recycling of copper and aluminum in the electric vehicle battery and the most expensive and rare "lithium", which not only realizes the harmless disposal of harmful substances, but also reuses the recycled materials for the production of battery materials to realize resource recycling. .

Thanks to Zhao Guangjin's unremitting efforts, the Provincial Electric Power Research Institute has innovated and built the first domestic dry-process automatic power battery recycling production line. The production line has abandoned the traditional fire method, wet method and other high energy consumption and high pollution recovery treatment technology. It has the characteristics of high recovery efficiency, energy saving and environmental protection, no secondary pollution, etc. The processing capacity per hour is 800 kg and the annual processing capacity is 5,000 tons. The recycling rate of valuable components of used lithium batteries is over 90%. The production line realizes the recycling of battery materials, solves the "bottleneck" and "worry" of the sustainable development of energy storage and new energy vehicles, and has made due contributions to promoting the clean development of energy in China.

Ultra Low Temperature Infrared Pyrometer

This classification includes one color infrared pyrometers measuring range is 0℃-1000℃. The one color pyrometers currently on market are mostly narrow-band pyrometers. Its principle of temperature measurement is to determine the temperature by detecting the radiant energy that occurs in a narrow wavelength range (8-14μm for 0-1000C pyrometer) of an object. The temperature a pyrometer measured is the average temperature in an area, and the measuring result is affected by emissivity, lens contamination and background radiation.
