The gradient temperature was manipulated to construct hollow irregular carbon spheres with regulated intrinsic defects and surface area targeting favorable potassium storage. An enlarged surface area, increased intrinsic defects, and superior conductivity induced more surface-active interfaces. These actions facilitated a high reversible capacity as well as excellent cycling stability.
通过控制梯度温度来构建具有可控固有缺陷和表面积的空心不规则碳球，以实现良好的钾存储性能。增大的表面积、增加的固有缺陷和优异的导电性诱导了更多的表面活性界面。这些因素促成了高可逆容量以及出色的循环稳定性。
