Recently, Tang Yongbing, a researcher in the Research Center for Functional Thin Film Materials of the Institute of Integration, Shenzhen Academy of Advanced Technology, Chinese Academy of Sciences (the first unit communication), and Li Zhensheng, a professor of City University of Hong Kong (joint communication) successfully developed a new battery based on anion hybrid strategy. The related research achievement "Hybrid Anions to wards Fast Diffusion Kinetics for Tri Ion Batteries with Significantly Improved R

1、 Why study solid state battery? At present, lithium ion batteries based on liquid electrolyte are increasingly difficult to meet the long-term requirements of consumers in some application scenarios, such as electric vehicles and intelligent electronic products. For this reason, researchers combine Li metal as negative electrode with sulfur, air (oxygen) or positive electrode with high content of layered nickel oxide to prepare batteries with higher energy density. At the same time, due to the potential safety

The scale of the global lithium ion battery industry is expanding rapidly, and lithium cobalate is the main cathode material in the small lithium battery category. In 2012, lithium-ion batteries accounted for 41% of the global demand for lithium terminals, of which the cathode material was the core key material, accounting for 30-40% of the cost of lithium-ion batteries. It is estimated that the scale of the global lithium-ion battery industry will reach 27.81 billion US dollars by 2013. In 2015, the industrial use

Although lithium-ion batteries are the main energy storage force today, there are still many research groups and manufacturers trying to find more stable and effective energy storage technologies than lithium-ion batteries. Recently, the National Renewable Energy Laboratory (NREL) of the US Department of Energy successfully developed magnesium solid state batteries, and the energy density and material cost of the prototype battery are better than lithium ion batteries.(Lithium - Ion Battery Equipment) Normally,

What is the test method of lithium diaphragm technology? 1. Thickness There are two important online control technologies for the diaphragm thickness of lithium ion battery, one is MD (vertical) control and the other is CD (horizontal) control; The other is diaphragm online machine vision testing technology. The so-called MD control and CD control refer to the thickness closed-loop control in the MD direction by controlling the feeding screw speed or traction speed; As well as the data measurement through the

According to foreign media, BatteryAdvanced Development Inc., California The company develops breakthrough battery technology, using a special combination of chemical substances as electrodes and electrolytes. At present, some new batteries use special rare chemicals, but the raw materials of such batteries can be easily obtained from existing resources. The company is applying for a patent and is committed to producing a landmark product, hoping to further expand the production scale. At present, the specifi

Why not change the electric bicycle into lithium iron phosphate battery? Recently, a car friend left a message asking about this problem. The reason why lithium ion batteries are not suitable for your electric bicycles can be summarized in one word. Lithium ion iron phosphate batteries have no heavy metals, the battery recovery rate is more than 95%, and the electrolyte is almost pollution-free. Some types of batteries can even be drunk. Of course, the price of batteries with so many advantages is not low.(Lithium

During the National Two Sessions this year, the discussion on hydrogen energy and hydrogen fuel cell vehicles was very warm. In the revised government work report, hydrogen energy was included for the first time, proposing to promote the construction of charging, hydrogenation and other facilities. This has become an important milestone in the development of hydrogen fuel cell vehicle industry. Hydrogen fuel cell vehicle is an important technical route of China's new energy vehicle industry and one of the &q

The energy density technology of lithium iron phosphate battery has been broken through. The poor energy density of lithium iron phosphate battery is a disadvantage known to the public. At present, the capacity density of lithium iron phosphate battery is generally about 150Wh/kg. Even if it is better, it is about 160Wh/kg. This is a big difference compared with the 200Wh/kg energy density of ternary battery. Breakthrough in energy density technology of lithium iron phosphate battery Now, some enterprises in
