“…Quinones were also applied to supercapacitors. [95][96][97] Supercapacitor capacitance was greatly increased by simply adding hydroquinone into the acid electrolyte (Figure 16(b)), 96 and the capacitance increase was attributed to the quinone redox reaction. Interestingly, quinone redox reaction at the anode caused hydrogen electrosorption to occur at the cathode by holding the anode voltage at a nearly constant value and consequently bringing the cathode potential to large enough values that can induce hydrogen electrosorption (see figure).…”

This tutorial review provides a general account of the electrochemical behavior of quinones and their various applications. Quinone electrochemistry has been investigated for a long time due to its complexity. A simple point of view is developed that considers the relative stability of the reduced quinone species and the values of the first and second reduction potentials. The 9-membered square scheme in buffered aqueous solutions is explained and semiquinone radical stability is discussed in this context. Quinone redox reaction has also been employed in various studies. Diverse examples are presented under three broad categories defined by the roles of quinone: molecular tool for physical chemistry, versatile electron mediator, and charge storage for energy conversion devices.

“…Since, the capacitance is the sum of the double-layer capacitance and pseudocapacitance (Faradaic) [11], these redox peaks arise as a result of the availability of surface functional groups [11,12]. Bichat et al who researched on seaweed as starting material for electrode observed that the profile of CV in 1 Molar H 2 SO 4 electrolyte produced a similar curve inour study [13].…”

Binderless activated carbon monoliths (BACMs) prepared from mixtured of pre-carbonized of fibers of oil palm empty fruit bunches (EFB) and green petroleum coke were used for preparing the carbon based supercapacitor cells. The symmetrical supercapacitor cells were fabricated by using two BACMs electrode prepared for each selected holding time of activation and various compression pressure. The electrochemical behavior of supercapacitor cells were measured at room temperature by using cyclic voltammetry (CV) technique. The maximum specific capacitance (C ) of the cells values were 35.9 and 82.5 F/g for holding time of activation of 1.5 and 2 h, respectively, at the compression pressure of 7.5 metric tons.

“…In this case, the internal supply consists of an energy harvester integrated with an RF front-end and an advanced low voltage regulator supported by a super-capacitor. The storage block of environmental energy is free of drawbacks and limitations that are inherent for the traditional galvanic cells [17,18]. The super-capacitors are maintenance-free, with low degree of wear.…”

Abstract. The idea of multiband development board designed to support and advance the technique of battery-less autonomous semi-passive RFID transponders is presented in the paper. The extra function of harvesting energy from the electromagnetic field of different radio communications systems, the ultra efficient power conditioner and the energy storage block are applied in the proposed construction. The facility of utilizing gathered energy is provided to support designers in developing applications of automatic object identification. Since the evaluation board is to work without a galvanic cell, the particular emphasis is put on the mechanisms that improve energy efficient operation of the whole electronic circuit. The construction principles and operation modes (charging, cold start, sleep with charging, sleep, measurement and cut-off) of the storage unit are described in depth in the paper. The preproduction batch of the demonstrators has been manufactured on automated assembly line at ELMAK Ltd. Company, according to the elaborated model. It confirms that the author's demonstrator of the battery-less autonomous semi-passive transponder can be reproduced on an industrial scale. On the basis of the preproduction series, the performance parameters of the final product have been estimated. The presented study should significantly contribute to the RFID technique therefore the authors set up the evaluation process of marketing research and product commercialization. fication of moving objects, e.g. in the public transport (AVI -automatic vehicle identification) [7]. So it can be concluded that the observed applicable potential of the RFID technology justifies the need to develop new designs of electronic transponders. New more sophisticated solutions of electronic tags will be a factor of innovative progress in the discussed scope of use. Transponder in RFID systemIn terms of hardware (Fig. 1), an RFID system consists of a read/write device (RWD), which includes a transmitter (TX) and a receiver (RX), its antenna and at least one electronic transponder that is intended for marking an object. Communication in this system (read/write data) is provided with one (single system) or with multiple transponders simultaneously (anti-collision system). The marked objects during the identification process may be placed in fixed points (static system) or may dynamically change their location (dynamic system). The interrogation zone (IZ) is the main parameter of the RFID system, because it determines the efficiency of a given automated process [5]. The size of the IZ strongly depends on the above mentioned arrangements of RWD and transponders.According to the main classification of the RFID systems it is possible to distinguish applications operating in the inductive or radiative coupling regime. In the first group, the carrier frequency f 0 is between 100 kHz and 135 kHz (typically 125 kHz) for the LF band or 13.56 MHz of the HF band whereas in the
