In the future, the development of cars is considered the diversification of energy. In terms of energy diversification, the electrification of electric vehicles or cars must be the future development trend of the future. I want to say that from two aspects, we can say that the driver's electrification is in the first aspect. We understand that after using the driver's electrification, it automatically gives back, so that the driving efficiency can be greatly improved. Then the second aspect is the divers

It is reported that the NS United Netails Coalition of the Ninjin Railway Jinda Group, Japan, released the first mixed power cargo ship equipped with lithium -ion batteries in Tokyo on March 4th in Tokyo. A maximum of about 6 hours can be sailed by the battery alone. The internal cargo ship "UTASHIMA" (499 -ton), which was completed on February 27, was 76.19 meters in length and 12.00 meters wide. It will be used to transport new steels for new daytime iron. The ship has 2828 battery packs composed of

According to foreign media reports, Bosch has recently announced that the company is developing a technology called BatteryinTheCloud. It is said that the technology can extend the service life of electric vehicle vehicle batteries by 20%. The specific method is that Bosch connects the battery to the Bosch Cloud System, and continuously monitor and analyze the pressure of the battery bearing according to different driving styles and environment. This information can then be used to predict the remaining operatio

The reporter learned from Central South University that Professor Lei Yongpeng's team of the school developed a graphene gas gel electrocatalyst that can be used for recharge zinc-air batteries. First, performance is comparable to it. Related results were published in the Energy Express of the American Chemistry Association, an internationally renowned academic journal. Lei Yongpeng introduced that zinc-air batteries are more "high-end" than batteries such as lithium ions and lithium iron phosphate

Scientists are extremely excited about the emergence of graphene substances. They believe that it has huge industrial potential, and even predicts that it will subvert the era of chips led by silicon and set off a technological revolution in the future. In 2004, physicist Andre Gam, a physicist at the University of Manchester, and Constantine Novosholov successfully separated from graphite, confirmed that it could exist alone, and the two also won 2010 Nobel Prize in Physics.(Lithium - Ion Battery Equipment) So,

The performance of high -voltage lithium battery depends on the structure and properties of active materials and electrolytes. The positive material is the most critical core material, and the matching effect of the electrolyte is also important. At present, the most widely used high -voltage cathode material is a two -dimensional layered lithium cobalt oxide. This structure is & alpha; -nafeo2, which is more suitable for insertion and removal of lithium ions. The theoretical energy density of lithium cobalt

Carbon battery structure: Internal: mangible manganese dioxide and carbon mixed with ammonium chloride substances, dipped in ammonia -chloride paper, carbon rods (with conductive graphite), insulator Outside: copper hat (positive pole), zinc plate (negative pole), packaging plastic Principles of carbon battery structure: Zinc -manganese dry battery is a dry battery commonly used in daily life. Positive Materials: MNO2, Graphite Stick Negative material: zinc tablet Electrolyte: NH4CL, Zncl2 and star

The positive material can be five types: lithium cobaltate, lithium manganate, nickel cobalt lithium manganese, lithium iron phosphate, nickel cobalt aluminum lithium, lithium ion battery ternary positive material occupies a large proportion. Lithium -ion battery ternary positive material, which is used in the low -landing cost, improves the segmentation of materials and the unclear layout. However, the high manganese content will crush the layer of the material to make the ratio of the material lower. Becaus

The formation of lithium branch crystals is a technical problem that the lithium battery industry cannot avoid. As long as the lithium -ion battery is charged and discharged, lithium -ion will form lithium branches crystals. And after a long period of accumulation, when the lithium branch crystals grow to a certain length, the diaphragm will cause a short circuit inside the lithium -ion battery. Once a short -circuit light in the lithium -ion battery is scrapped Life is safe.(Lithium - Ion Battery Equipment) In
