“…This effect can occur because Li + ions have a relatively small size and a higher charge density than other alkali metal ions, making them more strongly attracted to the negative groups of the CMC. As a result, these interactions can disrupt the hydrophilic interactions, which means the presence of LiCH 3 COO salt can decrease the hydrophilicity of the CMC 13,86 …”

“…As a result, these interactions can disrupt the hydrophilic interactions, which means the presence of LiCH 3 COO salt can decrease the hydrophilicity of the CMC. 13,86 Based on TGA, the pure CMC SPE film exhibits two degradation stages that are depolymerization and decarboxylation. The depolymerization occurs in the temperature range of 262.18 to 310.65 C, with the highest degradation rate occurring during the thermal change at 276.38 C. Meanwhile, decarboxylation followed by thermal decomposition occurs at a temperature of 479.66 C, with the maximum degradation rate occurring at 485.73 C. This process involves dehydration, followed by rearrangement and the formation of carboxyl and carbonyl groups, eventually resulting in the release of carbon dioxide (CO 2 ) and carbon monoxide (CO).…”

Polymer electrolyte is a crucial component of solid‐state‐lithium‐ion batteries that role both as separators and electrolytes. The host polymer and lithium salt selection are crucial for producing a solid polymer electrolyte with optimum characteristics. This research aims to study the effect of lithium acetate (LiCH3COO) salt on carboxymethyl cellulose (CMC)‐based solid polymer electrolytes. The LiCH3COO‐complexed CMC solid polymer electrolyte was prepared using the solution casting method with various weight percentages of LiCH3COO, that is, 0%wt, 10%wt, 20%wt, and 30%wt. The ionic conductivity analysis was conducted by using electrochemical impedance spectroscopy (EIS), infrared analysis by Fourier transform infra‐red (FTIR), mechanical analysis, crystallinity degree analysis with X‐ray diffraction (XRD), and thermogravimetry analysis (TGA), differential thermogravimetry (DTG), and differential scanning calorimetry (DSC). The interaction between Li+ ions and CMC enhanced ionic conductivity, decreased mechanical strength, reduced crystallinity degree, and lowered thermal properties. The CMC/LiCH3COO (70/30) SPE was selected as the optimum condition because it exhibited good ionic conductivity and sufficient thermal stability, while it needs a mechanical strength improvement. Molecular dynamics simulations were also performed at the density‐functional tight‐binding (DFTB) level to unravel the molecular mechanism of the Li‐ion hopping in CMC. The CMC/LiCH3COO (70/30) showed the highest electrochemical window as high as 3.5 V. Based on the results, CMC complexed with 30 (%wt) LiCH3COO salt showed high potential as a polymer electrolyte for lithium‐ion battery applications.Highlights Fabrication of solid polymer electrolyte based on carboxymethyl cellulose complexed with lithium acetate salt was conducted by simple casting solution method. The 30%wt LiCH3COO into carboxymethyl cellulose (CMC)‐polymer host showed the highest ionic conductivity of 2.47 × 10−5 S cm−1. The 30%wt LiCH3COO‐complexed CMC shows some degradation peaks, they are water evaporation, decomplexation, depolymerization, melting, and completely degraded. The density‐functional tight‐binding method suggests that the Li‐ions hop both in perpendicular and parallel directions of the cellulose layers. The CMC/LiCH3COO (70/30) showed the highest electrochemical window as high as 3.5 V.

“… 32 The CMC of SDS increases with increasing LMFH concentration while the CMC values of LMFH & SDS mixtures were decreased by increasing the ionic strength of the electrolyte. Haq et al 33 reported that increment in temperature and concentration of surfactant, the conductivity of the surfactant solution was increased.…”

Cleaning products have a global market of around $33 billion in 2020 and play an essential role in daily life, providing consumers with important public health benefits. Surfactants are the main ingredients of cleaning products and they can effectively remove dirt, germs, and other contaminants from surfaces. Understanding the role of each surfactant class in a detergent formulation and their interaction with NaCl is of utmost importance for formulating efficient and sustainable cleaning products. This paper describes the study of ternary surfactant systems consisting of surfactants (sodium lauryl ether sulfate, alkyl polyglycoside, or betaine, three of the most commonly used surfactants in detergent formulations), water, and NaCl. The effects of concentration on critical micelle concentration, aggregate size, and rheological behavior were evaluated by dynamic light scattering and rheology techniques.
