Claim 1:
2. A method of improving fast-chargeability of a lithium secondary battery containing an anode, a cathode, a porous separator disposed between said anode and said cathode, and an electrolyte, wherein said method comprises packing particles of an anode active material to form an anode active material layer having interstitial spaces and disposing a lithium ion reservoir in said interstitial spaces, configured to receive lithium ions from said cathode through said porous separator when said battery is charged and to enable said lithium ions to enter said particles of anode active material in a time-delayed manner, wherein said electrolyte is a non-flammable quasi-solid electrolyte comprising a lithium salt dissolved in a mixture of a liquid solvent and a liquid additive, wherein said liquid additive, different in composition than said liquid solvent, is selected from tris(trimethylsilyl)phosphite (TTSPi), triallyl phosphate (TAP), ethylene sulfate (DTD), 1,3-propane sultone (PS), propene sultone (PES), alkylsiloxane (Si—O), alkylsilane (Si—C), liquid oligomeric siloxane (—Si—O—Si—), or a combination thereof and said liquid additive-to-said liquid solvent ratio in said mixture is from 5/95 to 95/5 by weight.
