The overall performance of lithium-ion batteries （LIBs） is closely related to the interphase between the electrode materials and electrolytes. During LIB operation, electrolytes may decompose on the surface of electrode materials, forming a solid electrolyte interphase （SEI） layer. Ideally, the SEI layer should ensure reversible lithium-ion intercalation in the electrodes and suppress interfacial interactions. However, the chemical and mechanical stabilities of the SEI layer are not usually able to meet these requirements. Alternatively, tremendous efforts have been devoted to engineering the surface of electrode materials with an artificial interphase, which shows great promise in improving the electrochemical performance. Herein, we present a comprehensive summary of the state-of-the-art knowledge on this topic. The effects of the arrifidal interphase on the electrochemical performance of the electrode materials are discussed in detail. In particular, we highlight the importance of three functions of artificial interphases, including inhibiting electrolyte decomposition, protecting the electrodes from corrosion, and accommodatinz electrode volume chanzes.

As one of new electrical energy storage systems, supercapacitors possess higher energy density than conventional capacitors and larger power density than batteries, integrating substantial merits with high energy, large power delivery, long cycle life, obvious safety, and low cost. However, the unsatisfying energy density is the inhabiting issue for the wide commercial applications. As the energy density(E, W h kg?1) is directly proportional to specific capacitance(C, F g?1) and the square of operating voltage(V, V), in this review, we summarize the recent progress in two sections: the exploration of high-performance electrode materials to achieve high specific capacitance and the construction of high-voltage supercapacitor systems for high working voltage. The progressive explorations and developments in supercapacitors could guide the future research towards high-performance, low-cost, and safe energy storage devices.
