example

[0107] In this example a set of cylindrically shaped 5-pole core members connected in parallel to two common bus bars (positive and negative), like the MC battery configuration shown in Figure 1, but with only half as many core members. The negative connector is connected to a tab extending from the core's anode foil (copper) with a coated graphite electrode and the anode connector connected to the core's cathode foil (aluminum) has compound M and compound The blended oxide electrode structure of F. Anode tabs made of nickel and cathode tabs made of aluminum are welded to the busbars using spot or laser welding techniques. The housing and support members are made of plastic material (polyethylene). For this example, a cylindrical cavity with a diameter of 18mm and a pole core member with a slightly smaller diameter (17.9mm) were used. The housing and lid are made of plastic material that is ultrasonically welded together and thereby creates a hermetic seal.

Abstract

A multi-core lithium ion battery (100) includes a sealed enclosure (116) and a support member (120) disposed within the sealed enclosure (116). The support member (120) includes a plurality of cavities and a plurality of lithium ion core members (102) which are disposed within the plurality of cavities. The battery further includes a plurality of cavity liners (124), each of which is positioned between a corresponding one of the lithium ion core members (102) and a surface of a corresponding one of the cavities.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 795,150, filed October 11, 2012. This prior application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to lithium ion batteries and more particularly to multi-cell lithium ion batteries with improved safety and reduced manufacturing costs. Background technique [0004] Due to the growth of applications such as electric vehicles and grid storage systems, and other multi-battery battery pack applications (such as electric bicycles, uninterruptible power battery pack systems, and lead-acid replacement battery packs), electrochemical power batteries (such as Lithium-ion battery packs) are in increasing demand. What is required for these applications is high energy and power density, but equally if not more important is the requirement of low cost manufacturing and increased safety t...
