Organic compounds are attracting attention as active materials for high-capacity rechargeable batteries because of lightweight and free from resource constraints. TCI has commercialized a high-capacity organic cathode active material DNP-Li which was developed by the National Institute of Advanced Industrial Science and Technology (AIST), Japan.
Appearance of DNP-Li
Typical charge/discharge curves during initial cycles (cited from Reference)
Multielectron-transfer type redox reaction, high capacity (416 mAh/g) and energy density (1.1 Wh/g) has been reported.1)
Application: preparation of electrodes and cells (cited from Reference)
As a positive-electrode, composite sheet composed of DNP-Li (a few milligrams per electrode), acetylene black, and PTFE is prepared by mixing them. The sheet is then pressed onto a mesh-type aluminum current collector. The battery performance is examined by assembling IEC R2032 coin-type cells with a positive-electrode, a lithium metal negative-electrode, separator, and electrolyte solution.
