    摘要： An electric storage battery and method of manufacture thereof characterized by a feedthrough pin which is internally directly physically and electrically connected to an inner end of a positive electrode substrate. A C-shaped mandrel extends around the pin and substrate end enabling the pin/mandrel to be used during the manufacturing process as an arbor to facilitate winding layers of a spiral jellyroll electrode assembly. The pin additionally extends from the battery case and in the final product constitutes one of the battery terminals with the battery case comprising the other terminal. Active material is removed from both sides of the outer end of the negative electrode in the jellyroll to allow room for adhesive tape to secure the jellyroll. The electrolyte is injected through the open end of the case after the endcap is welded to the negative electrode but before sealing the endcap to the case. The electrolyte is preferably injected through the C-shaped mandrel to facilitate and speed filling.

    摘要： The battery includes a positive electrode having a first active material on a positive substrate. The first active material includes LiNixCo1-x-yMyO2 wherein 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.
