Abstract

There is disclosed herein a method for preparing an electrode for a sodium-ion secondary cell, comprising the steps of: applying an electrode coating (204) along a coating axis (c) on an electrode substrate sheet (202) to form a coated substrate sheet, the electrode coating (204) comprising an active electrode material wherein the active electrode material comprises one of hard carbon or a Prussian Blue analogue; cutting the coated substrate sheet across the coating axis (c) into a plurality of portions (210); and calendering a portion of the plurality of portions, wherein the calendering comprises applying pressure with at least one roller (212) having a pressureapplying axis (p) aligned with the coating axis (c). Among other benefits, the risk minimization of damage to the electrode substrate is achieved. Also disclosed herein is an electrode prepared by the aforementioned method, a sodium-ion cell comprising such an electrode, a battery system comprising such a cell, and a vehicle comprising such a battery system.
