Summary: This study investigates the highly reversible proton-coupled MnIV and MnII conversion in mild aqueous buffered electrolyte using 3D free-standing electrospun CNF electrodes as conductive scaffolds. The experimental results show that the free-standing CNF electrodes can maintain high charge capacity and cycling efficiency even at high MnO2 loading. This combination could be a striking approach for developing high energy efficiency MnO2-based mild aqueous batteries.

Summary: The performance properties of lithium-ion battery electrodes are determined by the design of the coating composite microstructure. This study optimized the rheological properties of the graphite ink and utilized a specific printing process to manipulate the internal pore structure and electronic networks of high coat weight electrodes, resulting in improved performance and cycle life. Depositing electrodes via syringe showed enhanced electronic conductivities and diffusion coefficients, leading to better cycle life and higher energy density.
