电池型电容器技术发展趋势展望
摘要：发展可再生能源是实现“碳达峰、碳中和”目标的最重要保障之一。然而，太阳能、风能等新能源出力的不稳定性对储能器件的能量特性和功率特性都提出了更高要求。首先，对传统锂离子电池和超级电容器的技术特征进行论述，提出在新的电网储能要求下发展电池型电容器技术的必要性。然后，从正极材料的改进、负极材料的改进，以及极片结构、集流体与极耳的革新3个方面，详细讨论了电池型电容器关键材料的技术发展方向。最后，提出储能器件的三大核心要素及其“二合一”或“三合一”效应的搭配，以满足对成本、安全性、功率特性和能量特性的多样化需求，并对电池型电容器的发展趋势进行了展望。
Abstract:The development of renewable energy is one of the most important guarantees to achieve carbon peak and carbon neutrality. However, the instability of solar energy, wind energy and other new energy sources has shown higher requirements on energy characteristic and power characteristic of energy storage devices. This paper firstly discussed the technical characteristics of traditional lithium-ion batteries and supercapacitors, and put forward the necessity of developing battery-capacitors technology under the new grid energy storage requirements. Then, the technical development trend of key materials for battery-capacitors was discussed in detail from three aspects: the improvement of cathode materials, improvement of anode materials, and innovation of electrode sheet structures, current collectors and electrode tabs. Finally, the three key elements of energy storage devices and their “two-in-one” or “three-in-one” effects were proposed to meet the diversified demands of cost, safety, power characteristic and energy characteristic, and the development trend of battery-capacitors was prospected.
