Abstract
A lithium-ion battery includes a case, an electrolyte, a positive electrode, a negative electrode, and an auxiliary electrode. The positive electrode includes a current collector and an active material. The negative electrode includes a current collector and an active material. The auxiliary electrode includes an active material. The electrolyte, positive electrode, and negative electrode are disposed within the case. The auxiliary electrode is configured to selectively couple to the negative electrode to irreversibly absorb lithium from the negative electrode.
