help needed - chem assignment (1 Viewer)

[horseluver29]

Have been searching the internet for a solid week and can find no really useful information.
We have to do an assignment on galvanic cells (due on wednesday), and one part asks us to compare to cost of lead acid cells and vanadium redox cells.
Im thinking in terms of production costs, maintenance costs, capital costs, cost of operation etc.. but i can't find anything
ANY help would be greatly appreciated.

Environmental assessment of vanadium redox and lead-acid batteries for stationary energy storage

Abstract

The environmental impact of both the vanadium redox battery (vanadium battery) and the lead-acid battery for use in stationary applications has been evaluated using a life cycle assessment approach. In this study, the calculated environmental impact was lower for the vanadium battery than for the lead-acid one. The net energy storage efficiency of the vanadium battery was greater due to lower primary energy needs during the life cycle. Favourable characteristics such as long cycle-life, good availability of resources and recycling ability justify the development and commercialisation of the vanadium battery.
