LITHIUM-IRON DISULFIDE CELL DESIGN WITH CORE REINFORCEMENT
摘要
<p>A electrochemical cell design, with particular applicability to lithium-iron disulfide batteries, is disclosed. The cell includes a spirally wound electrode assembly with a central core. The core causes uniform expansion within the cathode. The core may also collapse and/or possess a cross sectional shape that differs from the cross sectional shape of the cylindrical container which houses the electrode assembly.</p>
