Developed precise gas chromatography for Li-ion and Li-metal batteries. Higher temperatures, nickel content significantly boost gas production, degradation. Revealed unique gas evolution in anode-free Li-metal batteries. Identified key conditions influencing gas production, battery design optimization.
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].
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 .
The are several gassing mechanisms attributed to the graphite electrode in lithium ion batteries, of which the primary source is through electrolyte reduction during the first cycle coinciding with the formation of a solid electrolyte interphase (SEI) on the electrode surface.
Oxidation reactions occurring at the cathode in lithium ion batteries. There are two regions of gas evolution attributed to the cathode in lithium ion batteries additional to the degradation of surface contaminants, at higher voltages electrolyte oxidation can be the main contributor to gas evolution.
