1. A leaf spring connector for lithium-ion battery cells comprising:
conductive sheet metal folded into a leaf-spring battery connector;
areas of material removed such that battery cell outgassing is not blocked during operation;
a header lip fold to maintain a ventilation path for outgassing;
a maximum spring travel distance to ensure a ventilation path for outgassing; and
a minimum spring travel distance to accommodate varying cell lengths.
