ArticleAsymptotic Cost Analysis of Intercalation Lithium-Ion Systems for Multi-hour Duration Energy Storage
Context & Scale
Today’s lithium-ion batteries are manufactured with many layers of thin electrode materials that store energy, layered on to copper and aluminum current collectors. Increasing the thickness of these electrode layers can reduce the balance of cell hardware costs, reducing the overall cost per kWh of energy stored. Adopting a bobbin cell format, which is widely used for alkaline batteries, offers further opportunities for increasing the thickness of the electrodes beyond the thicknesses achievable today for sandwiched layers of electrodes. Bobbin cell manufacturing costs have also been scaled down with the experience of alkaline cell manufacturers, offering opportunities for these cells to be produced, using existing lithium-ion battery materials, for less than $100/kWh at the cell level. Although not suitable for all applications, these cells are suited for long-duration (4+ h discharge) grid storage applications.
