Abstract: An electrochemical cell and a method of preparing the electrochemical cell are provided. The electrochemical cell, such as a lithium battery or a solid-state lithium ion battery, includes a first electrode having a solid polymer electrolyte deposited thereon, wherein the solid polymer electrolyte comprises a microporous polymer swollen with an organic carbonate liquid and a dissociable lithium salt, and a second electrode. The method of preparing an electrochemical cell includes providing the first electrode, immersing the first electrode in an electrolyte solution, depositing the solid polymer electrolyte on the immersed first electrode, and attaching the second electrode to an exposed surface of the solid polymer electrolyte, thereby forming the electrochemical cell. During operation, the solid polymer electrolyte is capable of growing a passivating polymer layer at an interface between the first electrode and the solid polymer electrolyte.
