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....
With the rapid development of portable electronic devices and electric vehicles, people are not only pursuing larger capacity and faster charging and discharging speed of lithium batteries, but also more concerned about how to ensure the safety of lithium battery use. Due to occasional inciden...
1. In low-power systems, replace the previous secondary battery with a lithium-ion capacitor.Lithium ion capacitors have a large capacity and low self discharge current. When combined with solar panels, they can utilize this characteristic by replacing the previous secondary battery with a lithium-i...
The problems arising from the combination of high nickel materials and electrolytes are relatively complex to solve and have a high technical threshold. If a company does not have sufficient research and development capabilities, it is difficult to produce electrolyte products that match high nickel...
At present, battery safety has gradually become a hot topic of discussion, especially with more and more people starting to use low resistance high-power atomizers, the safety of batteries has become more important. The most common type of battery on the market currently is the 18650 battery that we...
According to a paper published in the latest issue of Scientific Progress by American scientists, the concentration of lithium ions in lithium-ion batteries fluctuates, which explains the shorter lifespan of lithium-ion batteries and has the potential to help develop batteries that charge faster and...
