The reactor in Fig.1consists of a stack of individual cells, where each cell contains the sites where electrochemical charge-transfer reactions occur as electrolyte flows through them, as well as a separator (either an electrolyte-filled gap or a selective membrane) to force the electrons through...
in Li–S batteries. A critical issue is the formation and “shuttle effects” of soluble intermediate polysulfides during battery operation. Polysulfides bridge the solid insulating sulfur and lithium sulfide (Li2S), and partially mitigate the high resistance and sluggish electrochemical reactions of ...
Anatase TiO2 is an extensively studied anode material for lithium-ion batteries because of its superior capability of storing Li+ electrochemically. Here reversible lithium storage of TiO2 is achieved chemically using redox targeting reactions. In the presence of a pair of redox mediators, bis(...
