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

Fuel power cell is a power generation device that directly changes the chemical energy of fuel into electrical energy. The principle of fuel power cell is an electrochemical device, and its composition is the same as that of ordinary batteries. The single cell is composed of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and electrolyte. The difference is that the active materials of ordinary batteries are stored in the battery, so

Recently, scientists from the Brookhaven National Laboratory of the Department of Energy (DOE) and the University of Arkansas developed an efficient catalyst for extracting electricity from ethanol, which is a liquid fuel easy to store and can be generated from renewable resources.(Lithium - Ion Battery Equipment) The catalyst described in the Journal of the American Chemical Society controls the electro oxidation of ethanol in an ideal chemical path, thereby releasing the full potential of stored energy of liqu

On October 28, the Ministry of Industry and Information Technology issued an announcement to publicly solicit opinions on the Specifications and Conditions for the Automotive Power Battery Industry, aiming to strengthen the supervision of automotive power battery products, prevent low-level repeated construction, and promote the technological progress and large-scale development of power battery manufacturers. According to the opinion draft issued by the Ministry of Industry and Information Technology, the tract
