Effects of lithium perchlorate on the electrochemical performance of PVDF-HFP/CA composite-based solid-state electrolytes
Bibliographic record
Abstract
Composite-based polymer electrolytes have attracted considerable attention due to their high ionic conductivity and excellent electrochemical performance in energy storage applications. This study explores the influence of Lithium Perchlorate (LiClO 4 ) loading on the electrochemical performance of composite-based solid-state electrolytes (SSEs) based on a composite of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and 20% cellulose acetate (CA), referred to as PVDF-HFP/20%CA. Utilizing a solution casting method, four SSE samples were fabricated: a control (0% LiClO 4 ) and three samples with varying LiClO 4 concentrations (5%, 10%, and 15%). Comprehensive characterizations, including scanning electron microscopy (SEM), Fourier-transform infrared (FTIR), physical characterization, and electrochemical impedance spectroscopy (EIS) were conducted to assess the impact of LiClO 4 on the composites. The Nyquist plot and DC ionic conductivity analysis further validate the superior performance of PH20CA-15Li (PVDF-HFP/20% cellulose acetate with 15% LiClO 4 ), with ionic conductivity increasing from 1.15 × 10 −6 S cm −1 for the control sample to 3.7 × 10 −6 S cm −1 . Loss Tangent and Cyclic Voltammetry analyses underscore the dynamic electrochemical behavior and stability of PH20CA-15Li, with the voltage window expanding from 0.996 V in the control sample to 1.398 V, highlighting its enhanced dielectric properties and energy storage capabilities. Electrolyte uptake and porosity analyses reveal a decrease in both parameters with increased LiClO 4 content, suggesting a trade-off between electrochemical performance and physical properties. SEM and FTIR analyses show structural and chemical changes, confirming the interaction between LiClO 4 and the composite matrix. The study concludes that 15% LiClO 4 loading optimally balances conductivity with physical properties, making it a promising candidate for advanced solid-state electrolyte applications.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
