Buffering internal thermal surges: the role of precursor specific heat capacity in the microstructural integrity of LiNiO 2 cathodes

Key Points

• To investigate how precursor specific heat capacity affects the thermal management and microstructural integrity of LiNiO2 cathodes.
• Examined the correlation between precursor specific heat capacity and thermal stability of LiNiO2 grains.
• Analyzed the electrochemical performance under thermal stress conditions.
• Comparative assessments of grain uniformity and stability post thermal exposure.
• High specific heat capacity in precursors led to improved microstructural integrity of LiNiO2 grains.
• Cathodes displayed superior electrochemical stability compared to those with lower specific heat capacity.
• Uniform grain distribution correlated with enhanced overall performance metrics.
