2,3,6,7,10,11-Hexamethoxytriphenylene (HMTP): A new organic cathode material for lithium batteries

摘要: We propose a new organic cathode material for rechargeable lithium battery applications: 2,3,6,7,10,11-hexamethoxytriphenylene (HMTP). HMTP is composed of six methoxy functional groups substituted onto central triphenylene moiety. The cell, incorporating 40 wt.% material, exhibits full specific capacity at current densities up to 3 C. main advantage as lies in stable cell performance and negligible self discharge, even though the lower, similar 66 mAh/g, compared other materials. Cells with showed >95% retention initial discharge after 50 cycles 1 C self-discharge was not observed during month open circuit voltage measurements. latter due fact that nature radical fundamentally different from materials' radicals.
