Ion Deposition Biasing to Inhibit Dendrite Formation and Growth in a Metal Ion Battery Cell
DRIVE
December 31, 2020
A battery cell includes a current collector, separator, anode, and deposition biasing element. The anode is positioned between the current collector and separator, and includes an ion conducting ceramic material with a porous structure. The biasing element is positioned within the battery cell so as to bias ion deposition within the anode, during a charging process, away from the separator. A method for forming a battery cell includes electrospinning particles of material into a mesh to form an anode that includes an ionically conductive material. At least one biasing element is applied to at least one of the anode and a current collector. The anode is positioned between the current collector and a separator. The current collector and the separator are joined to the anode.
