Improved high-temperature energy storage properties of PEI-based films via constructing electric potential well

Key Points

• Energy storage performance enhances with montmorillonite-chitosan in the modified PEI films, indicating effective reductions in conduction loss.
• A marked improvement in high-temperature energy storage is achieved by constructing an electric potential well within the films.
• Observational analysis explores the addition of montmorillonite-chitosan to polyetherimide films for energy efficiency enhancement.
• The findings highlight the need for further research to optimize high-temperature energy storage solutions.
