About this Research Topic
The limited range of electric vehicles encourages researchers to improve the energy density of their energy storage devices. Although noticeable results of high capacity anode materials such as silicon and lithium metal have been achieved, it remains unclear how best to fully utilize such materials in commercial cells due to gassing and safety issues. In exploring cathode materials with high capacity and high operating voltage as a potential solution, cycling stability becomes a critical problem to be tackled. Great efforts have been made to optimize the composition and structure of cathode materials, so as to increase the cycle life, but it is equally important to stabilize the solid-electrolyte interface.
How to best construct a chemically and electrochemically stable solid-electrolyte interface lies in adjusting the surface composition and structure of the cathode materials. Many researchers have offered ex-situ or in-situ methods as possible solutions, however the underlying interfacial electrochemistry needs to be better understood.
In this Research Topic, we aim to collect contributions related to the interfacial electrochemistry of cathode materials for Li/Na ion battery, mainly the surface modification of cathode materials, together with detailed characterizations of surface composition, morphology, and structural transformation of cathode materials during the cycle life.
We welcome Original Research, Review, and Mini-Review articles. Areas to be covered in this Research Topic may include, but are not limited to:
• Novel strategies on surface modifications of the cathode materials for Li/Na- ion battery
