Tailoring Li-ion transport in hybrid biopolymer electrolyte from Maydis stigma for supercapattery applications
Corn Silk Biopolymer (CSBP), a potent biomaterial shed light on offering a sustainable solution to agrowaste and achieve waste valorization. Hybrid Biopolymer Electrolyte (HBPE) was synthesized using corn silk extract by simple solution casting strategy. Freshly synthesized [30wt % CSBP+70 wt % PVDF-Co-HFP] system exemplifies conductivity of 2.35 × 10−8 Scm−1 and while loading 3.2 v/v % LiClO4 salt, the conductivity increased to 4.05 × 10−4 Scm−1 at 25 °C. Structural studies indicate complex formation between the Li+ and polar groups within polymer-salt system. From FTIR studies, prominent peaks noticed at 1651 and 1628 cm−1 are due to the interaction of –C=O group with Li+ and 625 cm−1 for unbound ClO4−.Our best conducting system reveal Li+ ions (tion = 0.98) are the major charge carriers. Electrochemical behaviour from CV demonstrates a good reversibility with a specific capacity (Qs = 25.6 Cg-1) and specific capacitance (Csp = 10.67 Fg-1) at a scan rate of 1 mV s−1. Also, the relation between the peak current with different scan rates for CPL 2 system is estimated from the slope as b = 0.7 suggesting the extraordinary behavior of a hybrid battery and super capacitor offering a unique platform for the sustainable energy storage technology.
期刊介绍:
The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems.
Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal:
Low-dimensional systems
Exotic states of quantum electron matter including topological phases
Energy conversion and storage
Interfaces, nanoparticles and catalysts.
