Abstract
Official abstract text for this publication.
A lithium-ion battery having a wound electrode configuration includes a wound cell element that includes a positive electrode and a negative electrode, the positive electrode including a current collector and a first active material and the negative electrode including a current collector and a second active material. The second active material has a potential that is greater than 0.2 volts versus a lithium reference electrode. The wound cell element includes a region where an edge of the positive electrode is provided proximate an edge of the negative electrode and the second active material near the edge of the negative electrode does not extend beyond the first active material near the edge of the positive electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. A lithium-ion battery having a wound electrode configuration comprising: a wound cell element comprising a positive electrode and a negative electrode, the positive electrode comprising a current collector and a first active material and the negative electrode comprising a current collector and a second active material, wherein the current collectors of the positive and negative electrodes each include a leading edge, a trailing edge, and two lateral edges;…
