Knowledge about the energy density of lithium-air batteries

Introduction to lithium ion batteries / By

The lithium-air Li-O2 battery has a theoretical energy density much higher than that of the lithium-ion battery, and it has the highest energy density among the existing battery systems. If the weight of oxygen involved in the reaction is not considered, the energy density of lithium-air batteries can reach 11430W·h·kg-1, which is equivalent to fossil …

Precautions for bonding welding and bonding welding process

Precautions for bonding welding and bonding welding process

Introduction to lithium ion batteries / By

Principle of bonding welding.Bonding welding is also called ultrasonic aluminum wire welding. The principle is to use an ultrasonic generator to generate energy. The magnetostrictive transducer rapidly expands and contracts under the induction of a high-frequency magnetic field to generate elastic vibration, so that the corresponding vibration of the wedge is simultaneously applied to the …
