It is reported that the joint research team has developed a proton conductor for fuel cells. The conductor is based on polystyrene phosphoric acid and can maintain high proton conductivity at up to 200 ℃ and without water. The researchers of the team are from Los Alamos National Laboratory, the University of Stuttgart, the University of New Mexico and Sandia National Laboratories. Fuel cell is a promising technology, which can convert hydrogen into electricity through electrochemical process, and only drain wate

Nickel cobalt manganese is widely used because of its high specific capacity, long cycle life, low toxicity and low cost. Nickel is an important component in the redox energy storage of cathode materials for lithium ion batteries. How to effectively improve the specific capacity of materials by increasing the nickel content in materials is one of the current research focuses. 1 High nickel ternary material Generally speaking, ternary cathode materials with high nickel mean that the mole fraction of nickel in

The progress of science and technology has added the word "smart" to the name of glasses, watches, necklaces and other items we wear. Even the mobile phone used to make calls and send messages has become a smart phone. It is true that smart devices are more versatile, but is intelligence more convenient? I don't know anything else, at least not in charging. At present, the battery life of mainstream lithium batteries is only a few days, and wearable devices are generally small. The energy density o

Testing, scoring and verification are terms and conditions that project developers and investors like. After all, the adoption of these measures can reduce investment risks and increase trust in new technologies, regardless of the industry. In view of this, DNVGL, a global quality assurance and risk management consultancy, recently released the third generation battery performance scorecard. In DNVGL's evaluation this year, 22 battery manufacturers provided DNVGL battery scorecards with battery products for

On December 24, Longji Co., Ltd. announced that it would invest in the construction of the annual 3GW single crystal battery project in Leye, Ningxia. The battery technology uses the company's unique battery technology, which has no precedent in the industry. The 3GW battery project, with a total investment of 1.397 billion yuan, is expected to be fully put into production in December 2021. There is no precedent for battery technology, demonstrating the leading strength: the investment amount of equipment an

The core component of new energy vehicles is the power battery. However, the range is still the bottleneck in the development of battery technology. How to reduce power consumption to improve the battery range has also attracted people's attention. Researchers at the University of Florida in the United States have developed a new type of sensor that can operate without relying on battery power, so it can reduce the power consumption of car batteries.(Lithium - Ion Battery Equipment) Jennifer Andrew, one of t

At present, the design of hybrid electric vehicles (HEVs) and pure electric vehicles (EVs) is very attractive, but there is also a less obvious but significant development trend in the automotive industry: adding a 48V DC bus to the power system. 48V is not only suitable for hybrid vehicles and pure electric vehicles, but also for more ordinary internal combustion vehicles. It can be seen from Figure 1 that the market share of pure electric vehicles and hybrid vehicles is growing.(Lithium - Ion Battery Equipment)

1 Introduction to Urbanization The term "urbanization" was widely used by Spanish scholar Zeda in 1867. In China, it is also translated into urbanization or urbanization. The so-called urbanization simply refers to the process of transforming rural population into urban population, or the process of transforming agricultural population into non-agricultural population. To be specific, it includes five aspects: the continuous increase of the proportion of urban population in a country or region, the way to

The theoretical specific energy of aluminum air fuel cell can reach 8100Wh/kg, which has the advantages of low cost, high specific energy density and specific power density. As a special fuel cell, aluminum air battery has great commercial potential in special, civil, underwater power system, backup power source of telecommunication system, portable power supply and other applications. Overview of metal air battery Lithium ion battery has a high specific energy, which is a secondary battery with mature resear
