Abstract

A rechargeable lithium-ion battery includes a positive electrode having a first capacity and 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 includes a lithium titanate active material. A liquid electrolyte that includes a lithium salt dissolved in at least one non-aqueous solvent a porous polymeric separator are located between the positive electrode and negative electrode. The separator is configured to allow lithium ions to flow through the separator.
