چکیده
The aim of this paper is to demonstrate lithium metal battery cells assembled with high potential cathodes produced by sustainable processes. Specifically, LiNi0.5Mn1.5O4 (LMNO) electrodes were fabricated using two different water-processable binders: pullulan (PU) or the bifunctional electronically conductive poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS). cell performance was evaluated voltammetric and galvanostatic charge/discharge cycles at C-rates 1M LiPF6 in 1:1 (v:v) ethylene carbonate (EC):dimethyl (DMC) (LP30) electrolyte compared that LMNO featuring poly(vinylidene difluoride) (PVdF). At C/10, specific capacity LMNO-PEDOT:PSS LMNO-PU were, respectively, 130 mAh g−1 127 g−1, slightly higher than LMNO-PVdF (124 g−1). While retention under repeated cycling similar, featured superior performance. Indeed, PEDOT:PSS a 100% over 200 carried out C/1 cut-off voltage 5 V. Overall, work demonstrates both binders are valuable alternative PVdF. In addition, use significantly improves cycle life cell, even when high-voltage used, therefore demonstrating feasibility production green can exhibit energy 400 Wh kg−1, electrode material level. Our further importance functional manufacturing.

Cationic fluorinated polymer binders for microbial fuel cell cathodes{
Fluorinated quaternary ammonium-containing polymers were used as catalyst binders in microbial fuel cell (MFC) cathodes. The performance of the cathodes was examined and compared to NAFION and other sulfonated aromatic cathode catalyst binders using linear sweep voltammetry (LSV), impedance spectroscopy, and performance tests in single chamber air-cathode MFCs. The cathodes with quaternary ammo...

متن کاملAir humidity and water pressure effects on the performance of air-cathode microbial fuel cell cathodes
To better understand how air cathode performance is affected by air humidification, microbial fuel cells were operated under different humidity conditions or water pressure conditions. Maximum power density decreased from 1130 30 mW m 2 with dry air to 980 80 mW m 2 with water-saturated air. When the cathode was exposed to higher water pressures by placing the cathode in a horizontal position, ...
