Vacancy-modified few-layered GaN crystal for novel high-temperature energy storage

Abstract

Exploring energy storage materials with ultralong cycle lifespan and high energy-power density in extremely high-temperature environments is key point. In this works, gallium nitride (GaN) crystal is applied in the...

Novel semiconductor materials for advanced supercapacitors

“…Lv et al 158 applied GaN crystals to high-temperature energy storage for the first time. Through an efficient and simple strategy, several layers of GaN crystals rich in N vacancies were designed and prepared, which further increased their specific surface area and active bits (Fig.…”

Gallium-based nascent electrode materials towards promising supercapacitor applications: a review

“…Further, they claimed that this work has opened up a new avenue for the application of GaN crystal materials. 30 …”

Silicon carbide single crystals for high-temperature supercapacitors

“…The dual carbon strategy requires the development of more energy-efficient, safe and reliable energy storage equipment to achieve sustainable economic development. [1][2][3] Compared with lithium batteries, supercapacitors (SCs), as a new type of energy storage equipment, have attracted much research attention due to their advantages of high power density and long cycle life. [4][5][6][7] To expand the operating temperature range of SCs and meet the needs of modern applications, 8 researchers have carried out a series of improvement studies on the selection of electrodes and electrolytes.…”
