One of the important quality indicators of ternary materials is particle size and particle size distribution The particle size and particle size distribution will affect the specific surface area, tap density, compaction density, processing properties and point chemical properties of ternary materials.

As smart phones and other digital products more and more popular, power range becomes most people's needs! The emergence of mobile power supply helps mobile phone, tablet power provide a long life, and it becomes the necessary digital technology products for business and travel,Sometimes, however, feel, a charging power with faster or charging treasure life wasn't up to individual needs.

Recently, Qi Lu, the Beijing university professor, published a speech report titled "Present Situation Analysis of Level 5V Lithium Ion Secondary Battery Technology Development" The following is the speech report records:Good morning, everyone! I'm very glad to have chance with you from the academic technology to explore the now common lithium battery problem, because the time is enough, today want to say two words else, ten days, the Beijing smog serious bad in this situation, it is also a very close relationship with us, it is said that will last for five days, five days after the national meteorological center said, will have a cold snap from Siberia.

High production research institute of lithium electricity (GGII) research shows that in the first half of 2016 China the lithium battery electrolyte shipped 39700 tons, which increased 654% from a year earlier.

A full range of storage battery lead mould, battery shell, positive plate and negative plate, separator, column connection pole lead plate, battery cover, charging flap, electrolyte, leadCar battery after a long time in the home, father often can't start the car, especially in the winter cold day, car dozen not dozen don't respond, so my father do it yourself for a 12 v battery charger, dad when I was young and like make electronic production, like to study Charger after the best dad let me share this charger to you, he said that in some places might be unreasonable, hope knowledgeable and dad communication, discussed the technology, many thanks! I put my dad's homemade process as experience, because he is layman don't understand, may in some places to write wrong, please forgive me!The most before the first of all, need a 12 v battery charger circuit diagram, dad said it is good to have the figure made, in accordance with the drawings can be clear, convenient to begin production.

Lithium battery is in the development of a bottleneck stage The energy density is close to its physical limits.

It is reported that the United Nations "Sample Proposal about Dangerous Goods Regulations" (TDG) 20 edition revised regulations has been officially released in July 2017TDG regulations is the United Nations in the 50 s of last century in order to standardize the international carriage of dangerous goods specially formulated for legal documents.

Since the industrialization of lithium ion batteries in 1991, graphite has unified the whole country of battery anode materials Lithium titanate as a new type of lithium ion battery cathode materials, it grabbed the attention because of its many excellent properties in the late 1990 s.

The growth of the ternary battery market space directly stimulates the simultaneous expansion of upstream materials, and the quality requirements of materials are becoming more demanding In order to improve product quality, many materials companies have further extended to the upstream.

According to the data of the National Federation of Manufacturers, the sales volume of new energy passenger vehicles reached 73,000 in April, a year-on-year increase of 150%, an increase of 31% from March Dongshu Cui, secretary-general of the National Federation of Trade Unions, pointed out that the surge in sales in April is a good manifestation of the new energy passenger cars gradually getting rid of the policy dependence, especially the sales of plug-in hybrids and A-class electric vehicles are growing rapidly.
