Benefits

LiDFP is gaining attention as an additive in lithium-ion batteries due to its unique properties. Here are some potential benefits of including LiDFP in battery formulations.

Improved cycling stability. LiDFP helps form a more uniform, stable, and strong solid electrolyte interface (SEI) layer, which can effectively reduce electrolyte decomposition and thus improve the battery's cycle stability.
Enhanced stability. LiDFP can improve the electrochemical stability of the electrolyte, which helps prevent decomposition at high voltages, thereby extending the battery's lifespan.

Improved conductivity. The addition of LiDFP can enhance the ionic conductivity of the electrolyte, leading to better charge and discharge rates, which is crucial for high-performance applications.
Improved safety. The addition of LiDFP may contribute to the safety of lithium-ion batteries by reducing the risk of flammability compared to conventional electrolyte formulations.
Compatible with high-energy cathodes. LiDFP can be particularly beneficial in combinations with high-energy-density cathodes, enabling the development of batteries with higher specific energies.
