LITHIUM-ION BATTERY

摘要

A lithium-ion battery a lithium-ion battery that includes a first electrode that includes a first current collector having a first active material provided on at least one surface thereof The battery also includes a second electrode that includes a second current collector having a second active material provided on at least one surface thereof The second active material has a potential that is greater than 0.2 volts versus a lithium reference electrode. The first and second electrodes are folded accordion-style to form a cell element having a plurality of generally planar regions and a plurality of curved regions. The first active material forms a substantially continuous coating along substantially the entire length of the first current collector.
