Abstract
Provided is a lithium secondary battery containing an anode, a cathode, a porous separator disposed between the anode and the cathode, an electrolyte, and a lithium ion reservoir disposed between the anode and the porous separator and configured to receive lithium ions from the cathode when the battery is charged and enable the lithium ions to enter the anode in a time-delayed manner, wherein the reservoir comprises a conducting porous framework structure having pores (pore size from 1 nm to 500 μm) and lithium-capturing groups residing in the pores, wherein the lithium-capturing groups are selected from (a) redox forming species that reversibly form a redox pair with a lithium ion; (b) electron-donating groups interspaced between non-electron-donating groups; (c) anions and cations wherein the anions are more mobile than the cations; or (d) chemical reducing groups that partially reduce lithium ions from Lito Li, wherein 0<δ<1.
