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 [35, 36, 37].
Why is spectrometry important for detecting gas production in rechargeable batteries?
The operation of rechargeable batteries is always accompanied by the generation and accumulation of gases due to side reactions. Timely detection of gas production is particularly critical for ensuring battery safety and extending operational lifetimes. In this review, an emerging spectrometry technique—in s

What is electrolyte decomposition in lithium ion batteries?
Electrolyte decomposition is a central driver of gas generation and thermal runaway in lithium-ion batteries. Liquid electrolytes, primarily composed of LiPF 6 and carbonate solvents, undergo redox reactions and thermal degradation under abusive conditions.
What causes gas generation in lithium-ion battery anodes?
Gas generation in lithium-ion battery anodes is primarily driven by electrolyte reduction, the dynamic evolution of the SEI, and lithium dendrite growth. The produced gases (e.g., H 2, CH 4, C 2 H 4) critically influence cycle life, failure modes, and thermal runaway risks.
