What is the energy density? First, let's simply understand what the battery energy density is. There are two types of energy density: weight energy density and volume energy density. At present, the most referenced is weight energy density. Its calculation formula is: weight energy density=battery capacity× Discharge platform/weight, in Wh/kg (watt hour/kg); The calculation method of bulk energy density only needs to change the weight of the above formula into volume, in Wh/L (watt hour/liter). In s

The AGM battery uses pure sulfuric acid aqueous solution as the electrolyte, and its density is 1.291.3lg/cm3. Most of them exist in the glass fiber membrane, and at the same time, there is a part of electrolyte inside the electrode plate. In order to supply the oxygen released from the positive electrode to the channel of the negative electrode, it is necessary to keep 10% of the pores of the diaphragm not occupied by the electrolyte, that is, the lean solution design. The pole group is tightly assembled so that t

Requirements and application of lithium ion battery electrolyte. At present, solid-state lithium-ion batteries can be divided into inorganic solid-state electrolyte batteries and polymer solid-state lithium-ion batteries. The performance of electrolyte has a crucial impact on the performance of the whole battery. It has a very important impact on the battery cycle performance, operating temperature range and battery durability. For lithium-ion batteries, the composition of electrolyte involves at least two aspects:

The Zhongguancun Forum continued to be held today. According to the Beijing News, Wei Chang, president of the Beijing Institute of Low-Carbon and Clean Energy, said in an interview that the researchers of the Beijing Institute of Low-Carbon and Clean Energy independently developed a new type of quick-charging lithium battery, which can be fully charged in 5 minutes. This new lithium battery can be applied to two-wheel electric vehicles, new energy vehicles, etc. At present, this product is still in the trial sta

Researchers at Monash Energy Research Institute have created a more durable, lighter and sustainable lithium-sulfur battery only by adding sugar. With the assistance of CSIRO, the Australian national scientific institution, the Monash research team reported in Nature Communication that they had successfully stabilized the lithium-sulfur battery technology by using glucose-based additives on the positive electrode, which is called the foundation of the next generation of batteries. Mainak Majumder, deputy dire

The online lithium-ion battery UPS power supply is a UPS with light weight, small size and large capacity. The online lithium UPS power supply can better solve the computer restart or shutdown caused by the transient change of voltage, such as the computer restart caused by the opening of an air conditioner, refrigerator, etc., and the restart caused by the surrounding large electrical equipment startup, lightning, etc. Lithium-ion battery online UPS is a new generation of dedicated power supply products designe

Lithium ion battery manufacturers interpret the production process and procedures of lithium ion batteries. Mixing, coating, winding and testing are important production processes of lithium ion batteries. The process technology of lithium ion batteries is very strict and complex. The safety performance of lithium ion battery products is directly related to the life and health of consumers. The production and manufacturing of natural lithium ion batteries have high requirements for the performance, accuracy, stabil

What is Bohm stone Boehmite（ γ- AlOOH) is an important component of bauxite and an important chemical raw material with unique crystal structure. It is widely used in many fields, such as catalysts and carriers, paper fillers, inorganic flame retardants, etc. Especially as a precursor, it can prepare aluminum oxide, which is widely used in ceramics, electronics, adsorption and catalysis, and has broad application prospects. At present, the preparation of inorganic nanomaterials with specific morphology has

According to media reports, Estonian start-up Skeleton Technologies is developing a graphene enhanced SuperBattery, which can be fully charged in 15 seconds and will not deteriorate after hundreds of thousands of charge-discharge cycles. In addition, it was also reported that the company recently signed a letter of intent worth 1 billion euros with a leading automobile manufacturer to bring the technology to the market. According to Taavi Madiberk, founder and CEO of Skeleton, the technology may be listed as early
