(a) Capacity–voltage profiles of LC-CNT hybrid electrodes (LC hybrid) at various current rates and a pristine LC electrode at a 1C rate. (b) Capacity–voltage profiles of ALX-CNT hybrid electrodes (ALX hybrid) at various current rates and a pristine ALX electrode at a 1C rate. Capacity retention of the LC hybrid and ALX hybrid (c) at 1.0 and 2.0 A g−1 for 200 cycles and (d) at 5.0 and 10.0 A g−1 for 500 cycles. Capacity–voltage profiles of (e) pristine pteridine derivatives at 20 mA g−1 and (f) pteridine hybrid electrodes at 50 mA g−1 in sodium rechargeable batteries.
