Grafting effect on the wetting and electrochemical performance of carbon cloth electrode and polypropylene separator in electric double layer capacitor

Nanoporous separators for supercapacitor using activated carbon monolith electrode from oil palm empty fruit bunches

“…The GMs were carbonized at ~800 o C under N2 atmosphere with flow rate 1.5 litre/minutes to produce carbon monoliths (CMs). These CMs were activated with CO2 for 3 h with a multi-step activation process at ~800 o C and a flow rate of 1 litre/minute to produce ACMs [11,19,20]. All ACMs electrode were polished until thickness approximately ~0.4 mm.…”

“…or newly developed electrolytes. Beside active research activities in developing high surface area electrodes and high efficient electrolytes, there has also been growing research activities in developing supercapacitor separators; covering materials such as polypropylene [11], eggshell membrane [12], polyvinyl alcohol (PVA) [13], filter paper [14] and Teflon ring [5][6][7].…”

Radiation-grafted materials for energy conversion and energy storage applications

“…Polypropylene (PP) has been used in aqueous electrolyte-based supercapacitors [287][288][289]. However, PP is a semicrystalline hydrophobic polymer with low wettability in the liquid electrolytes.…”

A DC Power Distribution System in a Data Center using a Triple Active Bridge DC-DC Converter

“…Suggestions have been made to overcome the problem of backup by using an external system, such as a backup energy storage, which might help to ensure stability, especially during peak hours. Specific examples such as use of various batteries with different lifecycles, control technologies, and storage capacity have been discussed (9) (10) . Two types of batteries have been widely used for these purposes: leadacid and lithium-ion batteries.…”
