Surface structure and electrochemical characteristics of natural graphite fluorinated by ClF3

Microstructure and Charge–Discharge Characteristics of Ag–AgCl Coated Natural Bamboo Carbon

“…This is due to the existence of the functional groups and the microvoids. 10,11) However, the amount of Ag was more than Cl in the CA-650 electrode (treated at 650°C). It is known that AgCl was decomposed into silver and chlorine in the reducing atmosphere.…”

Effect of Surface Fluorination of Poly (p-Phenylene Terephthalamide) Fiber

“…Extensive studies have been performed on this matter 7 . Direct modification of polymer surfaces with fluorine 19 is particularly attractive since it is a simple and fast method that allows the simultaneous treatment of outer and inner surfaces of complex shaped polymer samples. The strong exothermal process can be controlled by lowering pressure (typically in the mbar range) and adjusting fluorine concentration (several vol.…”

Electrochemical cell studies on fluorinated natural graphite in propylene carbonate electrolyte with difluoromethyl acetate (MFA) additive for low temperature lithium battery application

“…Surface modification by fluorination is mainly dependent on particle size (surface area), it has negative effect in the smaller particle size (high surface area) where as it has a positive electrochemical effect in the case of the higher particle size (low surface area). [13][14][15][16] The effectiveness of the fluorination was explained at previous research articles. The results show that the effect of fluorination depends on the surface area via the particle sizes of the natural graphite i.e.…”

“…The efficiency of the samples was improved by the fluorination where as a small percentile of discharge capacity loss was observed due to the surface disorder. 15 In addition to that, an introduction of additive to electrolyte is a simplest way to minimize the solvent co-intercalation. Recently researchers have successfully proposed some additives.…”
