Abstract
, with 91.2% retention after 10 000 cycles. The outstanding supercapacitor performances are attributed to the synergistic effect between nano-graphite flakes and NiCr-LDHs, which provided abundant oxygen vacancies, high specific surface area and excellent conductivity for charge transfer and ion diffusion. The CDGE provides a simple, cost-effective, and green synthesis strategy for preparing NiCr-LDH nanosheets supported on exfoliated graphite in a single step.
