A hyperbranched conjugated Schiff base polymer network: a potential negative electrode for flexible thin film batteries

A hyperbranched conjugated Schiff base polymer network was synthesized by condensation between 4,4',4 ''-nitrilotribenzaldehyde and p-phenylenediamine. The material exhibits excellent rate capability and long cycle life for lithium storage. Coupled with lower electrode potential (0.7 V vs. Li+/Li), it may be well suited for fully flexible thin film polymeric batteries as the negative electrode.
