摘要:
随着环境污染与能源危机的加剧以及人类对能源的需求日益增长,亟需寻找一种新型储能器件替代传统的化石燃料。超级电容器因其高功率密度、长循环寿命、宽温度范围、高安全性、环境友好的优势,成为具有广泛应用前景的储能技术。然而,受制于比电容(C)低和电压窗口(V)窄的影响,超级电容器的能量密度难以满足储能市场的需求,严重限制了其实际应用。综述了如何通过微观形貌调控和晶体结构调控策略设计、优化层状金属氢氧化物以提高其赝电容性能,并详细阐述了上述策略增强层状金属氢氧化物能量密度的机理,展望了层状金属氢氧化物在未来超级电容器领域的发展前景。
Abstract:
As the series environmental pollution and energy crisis, and the growth of energy demand, it is very essential to develop novel energy storage device to replace traditional fossil fuels. Supercapacitors has been considered as a prospective energy storage device with broad application prospects due to the high power density, long cycle life, wide temperature range, high safety and environmental friendliness. However, the energy density of supercapacitors (E=1/2CV2) cannot meet the application requirements owing to the relatively low specific capacitance (C) and small voltage window (V). This review summarizes the strategies for designing and optimizing inorganic layered hydroxides to enhance the specific capacitance by morphology and crystal structure regulation, respectively. We also expound our viewpoints on the future development prospects of the layered hydroxides for energy storage applications.
