리튬 배터리 지식

Overcurrent and short circuit current

An overcurrent or short circuit is caused by an unknown cause (when the battery is discharged or the positive and negative electrodes are accidentally touched by metal). To ensure safety, it is necessary to stop the discharge immediately.

What is the cause of zero voltage or low voltage in a polymer lithium battery? The possible reasons are as follows:

Rechargeable lithium ion batteries power our phones and tablets they drive us from A to B in electric vehicles, and have many applications besides. Unfortunately, the devices that they power can fail and the batteries themselves are commonly only usable for two to three years. As such, there are millions batteries that must be recycled. Research published in the International Journal of Energy Technology and Policy describes a new way to extract the lithium and the cobalt that make up the bulk of the metal components of these batteries.
