Abstract

The invention discloses a button lithium battery, which comprises a negative electrode, a positive electrode, a separator, an electrolyte, a positive electrode shell and a negative electrode shell. The separator is sandwiched between the positive electrode and the negative electrode. One side of the positive electrode is the separator and the other side is coated with a current collector. A metal ring is disposed on the outside of the positive electrode. The metal ring and the current collector are integrated to form a ring mesh integrative positive electrode ring, and a ring mesh integrative positive electrode is formed after a positive electrode compact powder is coated by the ring mesh integrative positive electrode ring. The button lithium battery provides a high discharge platform and excellent power discharge characteristics, the utilization rate of the positive or negative electrode active material is greatly improved and the battery capacity is enhanced.
