Summary
Surface engineering with a NASICON-type coating enhances nickel-rich cathodes for high-energy lithium-ion batteries (LIBs). This improves structural stability and interfacial performance, enabling better capacity retention under high voltage conditions.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Nickel-rich layered oxides are key for high-energy lithium-ion batteries (LIBs) due to high voltage and capacity.
- Their application is hindered by structural degradation and interfacial instability at high voltages (≥4.5 V).
Purpose of the Study:
- To develop a robust nickel-rich cathode material with improved structural and interfacial stability for high-voltage LIBs.
- To enhance the performance and cycle life of LIBs through surface engineering.
Main Methods:
- Surface modification of LiNi0.83Co0.11Mn0.06O2 particles with a NASICON-type Li1.3La0.3Ti1.7(PO4)3 coating.
- Electrochemical testing to evaluate capacity, voltage, and cycle life.
Main Results:
- The Li1.3La0.3Ti1.7(PO4)3 coating suppressed lattice distortion and volume variations.
- The coating acted as a fast Li+ conductor, reducing interfacial impedance.
- It inhibited electrolyte oxidation and transition metal dissolution, stabilizing the cathode-electrolyte interface.
- The modified cathode achieved 178.8 mAh g-1 at 10 C and 89.21% retention after 100 cycles at 1 C (2.7-4.5 V).
Conclusions:
- Surface engineering with NASICON-type Li1.3La0.3Ti1.7(PO4)3 is an effective strategy for nickel-rich cathodes.
- This approach enhances structural robustness and interfacial stability for high-voltage LIBs.
- The modified material shows promise for next-generation high-energy-density LIB applications.
