Abstract
The battery includes a positive electrode having a first active material on a positive substrate. The first active material includes LiNiCoMOwherein M is chosen from the group consisting of Mn, Al, Mg, B, Ti, and Li, and wherein 0.5≦x≦1 and 0≦y≦0.3. The battery also includes a negative electrode having a second active material on a negative substrate. The second active material includes carbon. The negative electrode is susceptible to damage when a voltage exceeding a Damage Potential Threshold (DPT) is applied to the negative electrode. The DPT is lower than the maximum positive operating potential of the battery. The positive and negative electrodes define a Zero Volt Crossing Potential (ZCP) relative to a reference level when the voltage between the positive electrode and the negative electrode is zero. The positive electrode and the negative electrode are configured such that the value of the ZCP is less than the value of the DPT at a predetermined temperature.
