Abstract
ZnMn₂O₄ (ZMO) cathode possesses a high theoretical capacity of 224 mAh g^-1 and high operating voltage (1.9 V vs. Zn²⁺/Zn) for aqueous Zn–ion batteries. However, the disproportionation reaction of Mn³⁺ leads to Mn dissolution in the ZMO cathode, deteriorating lifespan. In this study, we attempted to reduce Mn dissolution by..... More

Abstract
Supercapacitor electrode slurry is prepared for mass production by mixing activated carbon powder, conductive agent, and binder, which is then deposited on a substrate using the doctor-blade method. Polyvinylidene fluoride (PVDF) and 1-methyl-2-pyrrolidone (NMP) are used as binder and solvent, respectively, to form the electrode slurry on a metal substrate...... More
