Mesoporous carbon cubes derived from high temperature heat-treatment of mesoporous crystalline fullerene C70 cubes showed excellent electrochemical supercapacitive performance.
Binder-free VG/TiNb2O7@S–C electrodes prepared via a powerful solvothermal-electrodeposition (ST-ED) method show good high-rate performance (241 mA h g−1/70 °C at 160C) and long high-temperature lifespan (>5000 cycles) at medium–high temperatures.
Substituting electroinactive Al3+ into vanadium ferrite aerogels boosts capacity to battery-relevant levels but in a material that expresses pseudocapacitive character and high-rate performance.
An external force field-assisted electrochemical exfoliation method was adopted to produce few-layered bismuthene nanosheets (FBNs). These FBNs exhibited a high rate performance and ultra-long cycle life for KIBs anode.
