What are the factors influencing the internal resistance of Li ion batteries

Temperature and environmental temperature are important factors affecting the resistance. For lithium-ion batteries, the temperature affects the activity of electrochemical materials, which directly determines the speed of electrochemical reaction and the speed of ion movement.

What should be paid attention to in spot welding of lithium battery

Because the positive plate of the electric lithium-ion battery cell is made of aluminum strip, tin can not be directly welded, so it is necessary to add nickel strip. Ultrasonic metal spot welding method is usually used: high frequency oscillation occurs by ultrasonic, which makes the friction between two metal plates heated locally, resulting in fusion connection. Frequency: 20K ~ 35kHz, time: about 0.3 seconds. Pay attention to the selection of suitable welding equipment for metal ultrasonic welder.

How to use lithium battery correctly?

Do not use lithium batteries (especially notebook lithium batteries) for a long time when the equipment is powered externally. Even if your laptop has good heat dissipation, a long-term 100% of the electricity is equal to the murder of lithium batteries.

Packaging technology of flexible lithium ion battery

There are dynamic electrochemical reactions in lithium-ion batteries, which are sensitive to water and oxygen. Organic solvents, such as electrolyte, will react with lithium salt in electrolyte to generate a large amount of HF when they meet with water and oxygen, which will affect the electrochemical performance (such as capacity and cycle life).

Development trend and application scenario analysis of global new battery

In 1799, Alessandro Volta, an Italian physicist, invented the first battery (vlotaic pile). He made the battery from zinc (anode) and copper (cathode) and paper (electrolyte) soaked in brine to prove that electricity can be manufactured artificially.
