Patent ID: 8383269

Claim:
A rechargeable lithium-ion battery comprising: a housing comprising titanium or a titanium alloy; a positive electrode having a first capacity and comprising an active material selected from the group consisting of LiCoO 2 , LiMn 2 O 4 , LiNiO 2 , LiCoPO 4 , LiCoPO 4 F, and LiFeMn 2−x O 4 (where O<×<0.5); a negative electrode having a second capacity that is less than the first capacity such that the battery has a negative-limited design, the negative electrode comprising a Li 4 Ti 5 O 12 active material; a liquid electrolyte comprising a lithium salt dissolved in at least one non-aqueous solvent; and a porous polymeric separator located between the positive electrode and negative electrode, wherein the separator is configured to allow lithium ions to flow through the separator; wherein the negative electrode has a capacity fade rate that is lower than that of the positive electrode.
