The PVA/CNP films with CNP concentrations ranging from 0 to 1 wt% were synthesized via mechanical mixing. Comprehensive characterization of the structural, morphological, and electrical properties revealed that CNP incorporation enhanced the crystallinity (XRD), resulting in a relatively uniform distribution (SEM). Electrical tests showed that at 1 wt% CNP, the material exhibited increased resistance and reduced electrical conductivity. This effect has been linked to the creation of trap sites and interactions between charged particles with an energy requirement of approximately 1 eV. The Nyquist plots identified a capacitive component (up to 10 nF at 0.5 wt% CNP), while correlated barrier hopping (CBH) was determined to be the dominant conduction mechanism, consistent with the observed morphological characteristics.

In this work, we report the electrochemical performance of LFMP cathode prepared using a microwave-assisted solvothermal process and subsequent carbon coating. Apart from comprehensive materials analysis, the electrochemical analysis has been conducted; the best sample delivered a discharge capacity of 134 mAh/g at 25 mA/g and 112 mAh/g at a higher current density of 300 mA/g. To understand the lithiation rate or delithiation rate, which plays a major impact on the performance, asymmetric charge–discharge rates between 25 and 300 mA/g were investigated. It is realized that the asymmetric condition of fast charging and practical discharge rate is suitable for LFMP to retain the benefit of higher Mn-redox voltage, in spite of a slight compromise on the capacity. The operando-X-ray diffraction studies were conducted to examine structural changes that occur during 1st charge/discharge cycle.
