Abstract
In electrochemical cells for medical devices having anodes assemblies, an anode assembly includes a folded lithium element having a first and second section. The first and second sections are for receiving a current collector therebetween. A method of forming an anode arrangement includes a step of folding a lithium element having the first and second sections with a current collector positioned therebetween. Thereafter, a pressing step is performed.
Claims5
An anode assembly for an electrochemical cell, the assembly comprising:
- a current collector element;
- a folded sheet lithium element having the current collector element embedded therein between first and second opposing sections of the folded sheet lithium element defined on opposite sides of a single fold line;
- said folded sheet lithium element having a first surface of the first section and a first surface of the second section pressed against the current collector element;
- and
- an insulator barrier band extending along a portion of the peripheral edge of the folded sheet lithium element.
