Electrochemical measurement of AHP binder. a The CV curve of S@AHP electrodes at a scan rate of 0.01 mV S−1 between 1.5–3.0 V. b (Dis) charge voltage profiles at 0.5 C (1C = 1672 mA/g). c, d The comparison performance between S@AHP, S@PTFE, and S@PVDF at a rate of 1 C, and the retention over 100 cycles. e Long-term cycling performance of S@AHP cathodes between 1.7–2.8 V with cycling performance and Coulombic efficiency at different current rates (0.5 C, 1 C, 1.5 C, and 3 C)
