Abstract
A current collector for an electrochemical cell includes a member having an outer member and an inner member coupled to the outer member by a plurality of flexible arms configured to allow the inner member to move relative to the outer member.
Claims20
A current collector for an electrochemical cell comprising:
- a member comprising an outer member and an inner member coupled to the outer member by a plurality of flexible arms configured to allow the inner member to move relative to the outer member;
- wherein between the inner member and the outer member, each flexible arm comprises a first portion and a second portion extending at a non-straight angle from the first portion.
A flexible current collector for an electrochemical cell, the current collector comprising:
- an outer portion;
- an inner portion;
- and
- a plurality of connecting members, each of the connecting members having a first end coupled to the outer portion and a second end coupled to the inner portion, wherein the connecting members are configured to allow the inner portion to move relative to the outer portion;
- wherein each connecting member includes an extension extending at a non-straight angle from the first end.
