The negative electrode of lithium-ion batteries is made by mixing the negative electrode active material carbon material or non carbon material, adhesive, and additives into a paste like adhesive that is evenly applied on both sides of the copper foil, and then dried and rolled. The key to the...

So what are the other issues when we charge our phones? Some people say that playing with a mobile phone while charging is not good, and this issue is also very controversial. Here, the editor will also briefly explain it to everyone. In fact, this depends on different situations. If you charg...

However, the premise that charging and playing games is not harmful is that your charger and charging cable are original or comply with the national 3C standard. Counterfeiting small factories and other products are not within the scope of what I mentioned, and I dare not guarantee them. Many people...

Our mobile phone batteries are now lithium-ion batteries, and the charging temperature range of lithium-ion batteries is 0-45 degrees Celsius. When you play with your phone while charging, if it doesn't generate heat, it doesn't have a significant impact on the batte...

The main Technology roadmap of Solid-state battery are divided into three categories. The production process of polymer materials is close to the existing equipment, and the conductivity of oxides is higher than that of polymers. However, the solid solid contact is poor, and the conductivity o...

So far, Microbial fuel cell have been used in wastewater treatment systems through experiments under ideal conditions, but they often fail under actual and changing conditions. Microbial fuel cell lack regulators that control the anode and cathode potentials and therefore the cell potential. This ca...

In wastewater treatment, aeration is a process that consumes a lot of energy but requires the removal of pollutants. The pump blows air into the wastewater to provide oxygen for the microorganisms in the treatment tank. In return, these bacteria oxidize organic matter into carbon dioxide and r...

With the arrival of the retirement period for power lithium-ion batteries, the tens of billions market in the recycling field will also open up. According to relevant data, the amount of lithium-ion batteries loaded into new energy vehicles in China reached 36.27 GWh in 2017, and the cumulativ...

In January 2017, the General Office of the State Council issued the Implementation Method of Extended Producer Responsibility System, which defined the scope of extended producer responsibility as carrying out Ecological design, using renewable raw materials, standardizing recycling and streng...
