The present invention relates generally to a metal canned battery that does not suffer reduced effectiveness in mechanical reliability upon dropping or vibration. More particularly, the invention pertains to a metal canned battery that has a substance therein that causes the electrode assembly to adhere to the exterior can. In one aspect, the battery is of a winding type wherein a cathode and an anode sheet are wound along with a polymer separator between them to form a jelly roll that is inserted into a cylindrical or prismatic metal can. The jelly roll is wrapped with an adhesive polymer layer or the inner wall of the metal can is coated with an adhesive polymer layer. The polymer layer is capable of swelling in a non-aqueous liquid electrolyte to provide a good adhesive between the metal can and the jelly roll and thereby improve the mechanical reliability and safety of the battery during drop or vibration.

LiCoO2/graphite and Li[Ni1/3Mn1/3Co 1/3]O2/graphite pouch cells and Li[Ni 1-x-yMnxCoy]O2/graphite 18650 cells were made with varying concentrations of vinylene carbonate (VC) and studied using high precision coulometry, extended cycling as well as electrochemical impedance spectroscopy (EIS). As expected, adding increased concentrations of VC (up to 6 wt%) to the control electrolyte resulted in improved coulombic efficiency, decreased charge endpoint slippage and longer cycle life. However, high concentrations of VC led to larger charge transfer resistance, especially at the graphite negative electrode. Understanding how varying amounts of VC impact cell lifetime and impedance allows for optimized electrolyte formulations to be found for different applications that may balance lifetime and power demands. © 2013 The Electrochemical Society.
