Recently, Ye Sheng, a doctoral student under the guidance of Li Can, an academician of the CAS Member, the State Key Laboratory of Catalysis at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and a researcher of the Solar Energy Research Department, made new progress in the research of simulating natural photosynthesis to build an efficient artificial photosynthetic system. Based on the concept of bionics, researchers combined partially oxidized graphene and hole storage layer, greatly improv

The importance of battery for mobile devices is self-evident, but for now, it is still a short board. Although other technologies and performance of mobile devices are constantly improving, many large companies have failed to propose feasible solutions for battery technology upgrading in a short time. Battery is the weak link in the system Although the capabilities, speed and functions of smart phones have developed rapidly, the increase in battery life is much slower. For example, the CPU and GPU speed of th

On July 31, the national monitoring and traceability management platform for new energy vehicles (hereinafter referred to as the "management platform") was officially launched in Beijing University of Technology. Before the launch meeting, the reporter had an exclusive interview with Sun Fengchun, director of the National Engineering Laboratory for Electric Vehicles of Beijing University of Technology and academician of the CAE Member. Sun Fengchun said that China is the first country to implement the who

Scientists at Stanford University in California have demonstrated a new water electrolysis device that can produce hydrogen from brine. Although it is a mature technology to use electricity to decompose water to produce hydrogen, its commercial application has begun to appear in various markets. Most electrolytic cells need purified water to operate, and system components are rapidly degraded in the presence of salt. If technology is expanded to represent an important part of our energy structure, it may bring h

High nickel ternary battery is becoming an important way to improve battery energy density. In addition, in the field of lithium-ion batteries, including Guoxuan High Tech, Ningde Times and other giants are targeting research in cutting-edge fields such as solid electrolyte, lithium metal anode, etc. The competition in the battery industry is moving towards the upstream, which is also likely to produce disruptive key technologies. Recently, the research team of Chinese scientists published the latest research on ba

With the rapid development of the new energy vehicle market, the demand for power lithium-ion batteries continues to rise. In this context, many listed companies have accelerated the layout of solid-state lithium-ion batteries. Industry insiders said that solid state batteries have a longer range due to their higher energy density. With the improvement of recycling, safety and other comprehensive technical indicators, the solid-state battery application market will gradually expand.(Lithium - Ion Battery Equipment)

The demand for lithium-ion battery management chips is strong, and the market is expected to continue to rise. With the acceleration of the popularization of the application of fast charging in mobile phones, the demand for accurate measurement of lithium-ion battery management chips has increased. A higher proportion of high-end mobile phones will use lithium-ion battery measurement chips. Previously, some mobile phones used software to calculate battery capacity, which may not meet the specification requirements

Technical advantages and application of 48V lithium-ion battery pack system for vehicle use. The 48V light mix system is mainly composed of 48V lithium ion battery pack, motor with integrated AC/DC inverter and DC/DC converter. The 48V power supply system can store more power than the 12V power supply system. On vehicles equipped with the start stop system, the engine can be shut down for a long time to reduce the frequent starting of the engine due to low battery power. Technical advantages of vehicle mounted 4

With super fast charging, super long endurance and super safety, GAC E'an has announced that it will soon launch a new power lithium ion battery technology, which will stir up thousands of waves. On January 16, Ouyang Minggao, vice chairman of the China Electric Vehicle Hundred People's Association and academician of the Chinese Academy of Sciences, pointed out at the 2021 China Electric Vehicle Hundred People's Association Forum that "if someone said that his car could run 1000 kilometers and be c
