Here, we investigate HCs from a mixture of sugars (D-glucose and pectin) and polytetrafluoroethylene (PTFE) as an anode material for PIBs with special attention to the final product's yield and electrochemical properties as a negative electrode for potassium-ion batteries. 2. Materials and methods 2.1. Synthesis
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Employing the PTFE additives improves discharge capacity (285 mAh/g at C/10 charge/discharge rate), enhances rate capability (232 mAh/g at 1C charge/discharge rate) and cycling stability of HC as a negative electrode material for potassium-ion batteries that has been tested in both potassium half-cell and potassium-ion full cell configurations. 1.
The potassium-ion batteries (PIBs) worth considering as a possible alternative for stationary energy storage technology. Among numerous negative electrode (anode) materials for PIBs the carbon-based ones attract much attention as they deliver high electronic conductivity and promising electrochemical characteristics at relatively low cost.
As negative electrode material for sodium-ion batteries, scientists have tried various materials like Alloys, transition metal di-chalcogenides and hard carbon-based materials.
