摘要: Capacitive neutralization dialysis energy (CNDE) is proposed as a novel energy-harvesting technique that able to utilize waste acid and alkaline solutions produce electrical energy. CNDE modification based on dialysis. It was found higher NaCl concentration led open-circuit potential when the concentrations of were fixed. Upon closing circuit, membrane used driving force move counter ions into double layers at electrode–liquid interface, thereby creating an ionic current. Correspondingly, in external electrons flow through resistor from one electrode other, generating directly. The influence resistances studied achieve greater extraction, with maximum output 110 mW/m2 obtained by employing resistance 5 Ω together AC-coated electrode.
