[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...
