Cylindrical solar container lithium battery gas production

Are lithium-ion batteries cyclable?

Authors to whom correspondence should be addressed. Gas evolution in lithium-ion batteries represents a pivotal yet underaddressed concern, significantly compromising long-term cyclability and safety through complex interfacial dynamics and material degradation across both normal operation and extreme thermal scenarios.

Why are cylindrical batteries important?

The importance of cylindrical batteries is only growing because they are used widely from small electronic devices to EVs. In line with the trend, LG Energy Solution has continued researching and developing cylindrical batteries to improve their capacity and performance.

How does gas production affect lithium ion batteries?

As gas generation within lithium-ion batteries gradually increases, the battery first undergoes physical structural changes induced by gas accumulation. Continuous gas production in the confined space elevates internal pressure, causing cell expansion [ ].

What causes gas evolution in lithium ion batteries?

In lithium-ion batteries, gas generation at the anode is the primary source of gas evolution, particularly during the initial cycling process. During the first charge–discharge cycle, the electrolyte reacts with active lithium to form a SEI, generating significant gas at the electrode/electrolyte interface [ ].
