High-rate cycling performance of lead-acid batteries with nanostructured electrodes
2021
In this work we present lead-acid batteries with nanostructured electrodes cycled with different C-rate from 1C (1 hour to complete charge) up to 30C (120 seconds to complete charge) and imposing a very deep discharge. In comparison to the parameters usually used for commercial batteries, these are much more stressful conditions in terms of cut-off and charge/discharge rate.
Nanostructured lead-acid negative electrode with reduced graphene oxide
2021
Aim of this work is to develop a new nano-structured and nano-composite lead acid negative electrode with reduced graphene oxide (rGO). Nanostructured electrodes are fabricated by template electrodeposition of lead nanowires on a lead current collector. A polycarbonate track-etched membrane was used as a template (200 nm mean pores diameter). rGO was deposited on the nanostructured electrode from a graphene oxide (GO) dispersion in acetate buffer solution (ABS) (0.2 g/L). Potentiostatic deposition of rGO at -0.8 V vs. standard calomel electrode (SCE) was performed. Electrode with rGO was tested as negative electrode in cell with 5M sulfuric acid solution, a commercial pasted positive plate,…
