Lamellar graphene oxide stabilizes spinel LiMn2O4 cathode structure for high-temperature longevity

Key Points

• Longevity of LiMn2O4 cathodes increases with the addition of lamellar graphene oxide, providing structural stability.
• Enhanced electrochemical performance, measured through cycling stability, supports the benefits of graphene oxide integration.
• Assessment using thermal and electrochemical testing demonstrates the reliability of the stabilized cathodes under elevated temperatures.
• These findings may enable better battery technologies, yet further validation in real-world settings is necessary.
