Transition metal based battery-type electrodes in hybrid supercapacitors: A review

Electrode Materials for Supercapacitors: A Review of Recent Advances

“…(Figure 12b) Besides the enhanced stability, the highly pGr with excellent conductivity led to increasing the Ed and cycling performance (Figure 12c) of the resultant electrode [197]. As it was mentioned in the introduction section, the battery-type TM can be classified into two main groups depending on their electrochemical reaction in HSC device, including intercalation-type and conversion-type ( Figure 13) [199]. However, it is worth mentioning that, although TM-based materials are mainly categorized as battery-type materials, they also exhibit capacitive behaviour.…”

“…They reported that the liquid-phase and solid-phase diffusion were facilitated due to the formation of the highly porous nanostructure and enhancing the contents of hydrous states such as H−O−H, and Mn−O−H for the thick oxide layer [200]. As it was mentioned in the introduction section, the battery-type TM can be classified into two main groups depending on their electrochemical reaction in HSC device, including intercalation-type and conversion-type ( Figure 13) [199]. However, it is worth mentioning that, although TM-based materials are mainly categorized as battery-type materials, they also exhibit capacitive behaviour.…”

“…For instance, Zheng et al [208] synthesized a hydrous RuO2 through a sol-gel technique, which provided a specific capacitance of 720 F.g −1 at the annealing temperature of 150 °C. [199], Copyright 2020, Elsevier.…”

Электронная Структура Ультратонкой Пленки Окисла Молибдена

“…умных" окон, накопителей энергии, биосенсоров, катализаторов, фотои электрохромных материалов, эмиттеров для поверхностной ионизации в масс-спектроскопии и т. д. Одним из перспективных направлений использования окислов молибдена является создание накопителей энергии, при этом речь идет не только о разработке литий-ионных батарей и суперконденсаторов, но и об использовании других щелочных металлов вместо лития: натрия или калия, что может привести к резкому удешевлению устройств. Наиболее перспективным является создание натрий-ионных батарей на основе MoO 3 и MoO 2 [1][2][3][4][5][6][7]. Также следует отметить, что направление исследований нацелено на изучение морфологических и электрохимических характеристик систем натрий−окисел молибдена, а изменение электронной структуры окислов при интеркаляции ее натрием мало изучено.…”
