Impact of the Microstructure on Electrochemical Performances of Dilithium Benzoquinone Dioximate as a Positive Material for a Li-Ion Battery
Abstract
Herein we would like to highlight the impact of the material microstructure on electrochemical performances of dilithium benzoquinone dioximate (Li 2-BQDO) and its oxidized and self-polymerized version (PNND), a promising electroactive material for energy storage application. Li 2-BQDO showed a reversible exchange of two lithium ions at high redox potential (3.0 V vs. Li + /Li), acting as a lithiated organic positive electrode for lithiumions batteries. After a preliminary computational study, electrochemical performance of the oxidized form of Li 2-BQDO, which polymerize inside the cell, were also investigated. Thanks to TEM analysis coupled with XRD experiment the role of microstructure and crystal structure in the energy storage process was highlighted.
