Abstract: The present invention generally relates to electrochemical batteries, and more specifically, to the combined additives in the non-aqueous electrolyte for rechargeable lithium-ion batteries containing spinel-based cathode that may enhance the performance of the batteries. The mixed additives comprising of 1,8-bis(dialkylamino)naphthalene, wherein alky group is described by CnH2n+1, n=1 to 3, and vinylene carbonate (VC) are added to the electrolyte of the lithium-ion batteries greatly improve the capacity recovery and reduce AC impedance growth during the high temperature storage. The incorporation of the two kinds of additives within the electrolyte of the battery can also improve the high temperature cycling performance.

Abstract: 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.

Abstract: The loss in delivered capacity (capacity fade) after cycling non-aqueous rechargeable lithium manganese oxide batteries at elevated temperatures can be greatly reduced by depositing a small amount of certain foreign metal species on the surface of spinel in the cathode. In particular the foreign metal species are from compounds having either bismuth, lead, lanthanum, barium, zirconium, yttrium, strontium, zinc or magnesium. The foreign metal species are introduced to the surface of spinel by moderately heating either an aqueous treated mixture or a dry mixture of ready-made spinel and the foreign metal compound.

Abstract: An improved design and manufacturing method is disclosed for calendered, double side segment coated webs. By staggering the leading edges and/or the trailing edges of the segment coatings on one side of the web from those on the other side, web damage, including the incidence of breakage, can be reduced. Further, vibration and wear on the calendering apparatus can be reduced. The invention is particularly useful for heavily calendered webs such as the electrodes in non-aqueous rechargeable lithium ion batteries.
