Abstract: A rechargeable lithium-ion battery includes a housing including a titanium or a titanium alloy, a positive electrode having a first capacity and at least one positive active material selected from the group consisting of LiCoO2, LiMn2O4, LiNiO2, LiCoPO4, LiCoPO4F, LiFeMn2-xO4, LiAlxCoyNi(1−x−y)O2, and LiTixCoyNi(1−x−y)O2, a negative electrode having a second capacity that is less than the first capacity, such that the battery has a negative-limited design, and a negative active material that is configured to cycle lithium ions at a potential of greater than approximately 0.2 volts versus a lithium reference electrode, a liquid electrolyte including a lithium salt dissolved in at least one non-aqueous solvent, and a porous polymeric separator located between the positive electrode and negative electrode and configured to allow lithium ions to flow through the separator.
