The first rare earth power source in China -- capacitance nickel-metal hydride power battery has achieved a major breakthrough in the application of pure electric buses More than 100 buses have been running for tens of millions of kilometers safely, providing strong technical support for leading the rapid development of pure electric vehicles.

Preparation of pole pieces (1) Ingredients Positive electrode: put a proportion of polyvinylidene fluoride (PVDF) and nitrogen methylpyrrolidone (NMP) into the stir, mix in the mixer and adjust the stirrer speed; then add the positive active material and carbon black, vacuum, adjust the speed of the agitator Negative electrode: Mix the latex and water in a blender and mix to adjust the stirrer speed; then add CMS, vacuum and adjust the stirrer speed.

The life that sees electric car it depends on above all what, the car that just as its name implies is electric drive, can open of bright will see this electricity has how many, electric quantity is enough not enoughAlthough compared with the traditional fuel oil vehicle, the charge cost of electric vehicle is low, but because of the high price of electric vehicle itself, and the battery life is relatively not long, the replacement of the battery will also be a huge expense, so the cost barrier "battery maintenance has become the" roadblock "for the popularization of electric vehicle.

The “13th Five-Year” China Lithium Battery Cathode Materials Market Development and Forecast Report (2017 Edition) was released by Car Research Consulting analyzed 200 lithium battery cathode materials companies, including 39 lithium battery cathode materials Listed companies Detailed data on production capacity, production and sales, revenue, and profit of the company's cathode materials are reported in the report.

lithium battery expansion is normal, indicating that the lithium battery aging, does not store electricity, this is normal, there is no safety riskReasons for bulging:A small amount of gas is produced in the battery during charging and is generally absorbed during discharge.

There are seven main differences:1, different materials: lithium battery with carbon material (graphite) as the negative pole, with lithium compounds as the positive pole; The positive electrode is composed of nickel oxide powder and graphite powder, and the negative electrode is composed of cadmium oxide powder and iron oxide powder2.

In a recently released report, we analyzed the global market share of lithium ion battery, lithium polymer battery, thin film battery and zinc air battery in 2011-2016, and predicted the market share in 2017 The batteries are suitable for mobile phones, portable electronics and laptops, and are expected to power electric cars, which are also the basis of smart computing.

It goes without saying how important recycling performance is for lithium-ion batteries In addition, at the macro level, longer cycle life means less resource consumption.

Industry Trends 1 High energy density and fast charge are future technology trends 2.

The newly purchased mobile phone needs to use the electricity in the mobile phone first Then charge it, and it needs to be operated 3-4 times repeatedly, which is called so-called activation.
