A bipolar porphyrin molecule for stable dual-ion symmetric batteries with high potential

The small molecule 5,15-di(thiophen-2-yl) porphyrin (TP) was developed for new dual-ion symmetric organic batteries (DSOBs). It delivered a capacity of 150 mA h g(-1) at 0.2 A g(-1) with a high voltage of 2.7 V, and up to 1500 cycles were achieved. This work offers a new approach for developing high-performance dual-ion organic symmetric batteries.

A new small molecule, 5,15-di(thiophen-2-yl) porphyrin (TP), was developed for high-performance dual-ion symmetric organic batteries (DSOBs). It exhibited a capacity of 150 mA h g(-1) at 0.2 A g(-1) with a high voltage of 2.7 V, and demonstrated excellent cycling stability up to 1500 cycles. This study provides a new approach for the development of high-performance dual-ion organic symmetric batteries.
