Debonding Failure of the Rubber Sealing Layer–Concrete Lining Interface in Lined Rock Caverns for Compressed Air Energy Storage

Key Points

• Debonding failure occurs at the rubber sealing layer and concrete lining interface, impacting energy storage efficiency.
• Analysis identified that the interface degradation can compromise the integrity of compressed air energy storage systems.
• Observational analysis highlighted the significance of material interaction and potential failure mechanisms in lined rock caverns.
• The findings support the need for improved design strategies to prevent debonding failures in energy storage applications.
