Abstract
Fe3O4 nanoparticles synthesized by a base catalyzed method are tested in an All-Solid-State (ASLB) battery using a sulfide electrolyte. The pristine nanoparticles were morphologically characterized showing an average size of 12 nm. The evaluation of the electrochemical properties shows high specific capacity values of 506 mAhg−1 after 350 cycles at a specific current of 250 mAg−1, with very high stability and coulombic efficiency.
Highlights
The large development of Li-ion technology allows for a massive spreading of portable electronics, as well as for a progressive diffusion of electrical vehicles (EV)
Transition metal oxides associated with the conversion mechanism usually suffer from a series of issues intimately connected with the conversion reaction itself
Remarkable structural changes and volume expansion are associated with this mechanism,[6] eventually leading to pulverization and loss of contact between active material particles and the current collector, which result in poor electron and ion transport limiting the overall cycle-life
Summary
The large development of Li-ion technology allows for a massive spreading of portable electronics, as well as for a progressive diffusion of electrical vehicles (EV). We report the synthesis, characterization and evaluation of the electrochemical properties of pristine Fe3O4 nanoparticles synthesized from a base catalyzed method mechanically mixed with electrospun Polyacrylonitrile (PAN) derived carbon fibers as simple composite material.
