Abstract

A flexible polymer solid electrolyte material useful in battery technology is described. The flexible solid electrolyte comprises a first block that has the ability to solvate alkali metal salts. The flexible solid electrolyte comprises a second block that has the ability to incorporate lithium ions within microphase separated spherical domains, wherein the lithium ions are from a secondary lithium source. The flexible solid electrolyte further comprises a second lithium salt.
