There is an urgent global need for electrochemical energy storage that includes materials that can provide simultaneous high power and high energy density. One strategy to achieve this goal is with pseudocapacitive materials that take advantage of reversible surface or near-surface Faradaic reactions to store charge. This allows them to surpass the capacity limitations of electrical double-layer capacitors and the mass transfer limitations of batteries. The past decade has seen tremendous growth in the understanding of pseudocapacitance as well as materials that exhibit this phenomenon. The purpose of this Review is to examine the fundamental development of the concept of pseudocapacitance and how it came to prominence in electrochemical energy storage as well as to describe new classes of materials whose electrochemical energy storage behavior can be described as pseudocapacitive.

伪电容：从基础知识到高功率储能材料。

全球迫切需要电化学能量存储，其中包括可以同时提供高功率和高能量密度的材料。实现该目标的一种策略是利用拟电容材料，该材料利用可逆的表面或近表面法拉第反应来存储电荷。这使它们可以超越双电层电容器的容量限制和电池的传质限制。在过去的十年中，对伪电容以及表现出这种现象的材料的理解有了巨大的增长。
