Effect of magnetic field on the rate performance of a FeO/LiFePO composite cathode for Li-ion batteries.

Lithium iron phosphate (LiFePO or LFP) is a widely used cathode material in lithium-ion batteries (LIBs) due to its low cost and environmental safety. However, LFP faces challenges during high-rate operation and prolonged cycling. Magnetic field (MF) can enhance ionic conductivity and reduce polarization in the LFP cathode, particularly when magnetically sensitive iron oxide is added to the cathode.

Polycationic doping of the LATP ceramic electrolyte for Li-ion batteries.

All-solid-state Li-ion batteries (LIBs) with a solid electrolyte instead of a liquid one demonstrate significantly higher safety in contrast with the conventional liquid-based LIBs. An inorganic NASICON-type Li conductor LiAlTi(PO) (LATP) is a promising solid electrolyte with an ionic conductivity of up to 10 S cm at room temperature. However, LATP gradually degrades in contact with Li metal because of reduction of Ti to Ti, resulting in a lower ionic conductivity at the electrolyte-electrode interface.
