The lithium battery protection board is the charge and discharge protection for the series-connected lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), and realize the equal charge of the individual cells of the battery pack. , effectively improving the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperatur

The pursuit of zero-carbon emission vehicles in advanced countries around the world is becoming more and more popular, and the demand for new energy vehicle specifications has become increasingly clear. However, the current sluggish development of lithium battery technology restricts the cruising range and safety, making the upgrade of new energy vehicles slow. Recently The shocking battery fire accident of new energy vehicles has occurred again and again, forcing BMW, Toyota and other international car manufacture

On September 11, Germany's "Automobile Weekly" reported that Volkswagen announced a large-scale electric vehicle development plan "RoadmapE". By 2030, all Volkswagen models will have electric versions, investing 50 billion euros in electric vehicle batteries and 20 billion euros in electric vehicles. car. It is not new for OEMs to invest in batteries, and Volkswagen CEO Murren also said that they are already planning the next generation of electric vehicle batteries, solid-state batteries

All-solid-state lithium-ion batteries use solid-state electrolytes to replace traditional organic liquid electrolytes, which are expected to fundamentally solve the problem of battery safety. They are ideal chemical power sources for electric vehicles and large-scale energy storage. In order to achieve large capacity and long life, and thus promote the practical application of all-solid-state lithium-ion batteries, the development and performance optimization of key battery materials are urgent, including the prepa

lithium battery A primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, which is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. The inventor of the lithium battery was Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. Wi

As the most important technical path for the development of new energy vehicles, fast charging has a significant effect on relieving cruising range anxiety and reducing charging time, so it has also become the market choice of many car companies and battery companies. In the new energy vehicle subsidy adjustment plan released at the end of 2016, the fast-charging pure electric bus is regarded as a separate subdivision product, and a detailed subsidy standard is given: according to the electric capacity of the bu

The positive electrode materials of lithium batteries include lithium cobalt oxide LiCoO2, ternary material NiMnCo, lithium manganate LiMn2O4 plus conductive agent and binder, which are coated on aluminum foil to form the positive electrode, and the negative electrode is layered graphite plus conductive agent and binder. On the foil base tape, nano-carbon has been used in the relatively advanced anode layered graphite particles so far.(Lithium - Ion Battery Equipment) 1. Slurrying: Mix the powdered positive and

At present, scientists are working to develop new batteries with stronger energy storage and longer life, especially to develop more suitable batteries in different fields, because no one battery can be applied to all fields. Scientists are working on developing new lithium batteries 1. Not long ago, Chinese scientists developed a lithium battery that can be used at minus 70 degrees Celsius. It is expected to be used in extremely cold regions of the earth and even in outer space in the future. According to th

Consumer electronics, automotive and grid storage are three industries where batteries are currently used. Lithium battery manufacturer Xiaobian refers to these three industries as the three major areas where people connect with batteries. Each field has different requirements for batteries, so the batteries used can also be very different. The development of traditional lithium battery pack technology is slow, and the space for further optimization is limited. The phone in your pocket needs a sturdy, safe ba
