Electrolytes play a crucial role in various aspects of everyday life, participating in essential biological processes, technological applications, and industrial processes. Here are some key applications of electrolytes in daily life:Human PhysiologyBody Fluid Electrolytes, such as sodium, potassium...

Maintenance-free batteries actually eliminate the need for frequent addition of electrolyte, also known as distilled water. In theory, the lifespan of maintenance free batteries is generally 2-3 years. If used and maintained properly, it is not a problem to use them for more than 4 years. But if use...

What is the profit margin for the disposal of waste lithium batteries?At present, about 100 million mobile phone batteries are scrapped each year, with an average weight of about 20g per battery. The cobalt content is about 3g or more, and the current price of metallic cobalt is 400000 yuan/ton. Eac...

At 17:42 on the 22nd, a truck caught fire 200 meters away from the exit of the Beiliu toll station on the Guangzhou Kunming Expressway. A vehicle of semi-finished lithium batteries was burned, fortunately there were no casualties. After receiving the alarm, the Yulin Fire Br...

The compaction density of electrode surface coating materials is closely related to the electrochemical performance of batteries. A reasonable compaction density can effectively increase the electrochemical performance of batteries, reduce the contact resistance and AC impedance of electrodes,...

A 1500mAh rechargeable battery, fully charged. If the discharge current of 1500mA can reach 1 hour, it indicates that the capacity is sufficient. Still use 750mA discharge for 2 hours to detect. But when the voltage is 0.9V (1.2V rechargeable battery), there is still a nominal current released...

Does the rolling temperature have an impact on the performance of lithium-ion battery electrodes in the rolling process? This time, we will share a document that excerpts some of the explanations on the impact of roller pressing temperature on lithium battery electrodes. Polar plate rolling can be d...

The battery cover plate is a square shell battery top cover that seals the bare battery cell and isolates it from the outside. Each square shell battery is composed of a cover plate and a shell, and the cover plate mainly includes a top cover plate, positive and negative pole columns, explosion-proo...

What processes can be used to modify and optimize silicon in order to complement each other's strengths and weaknesses? Composite treatment of silicon with other substances can achieve good results, among which silicon carbon composite material is a widely studied material....
