Abstract
An apparatus for controlling a lithium-ion battery is provided in which a power-generating element including a positive electrode element and a negative electrode element is housed in a case, wherein the case contains a compound releasing an electron toward the positive electrode element to provide a proton at an electric potential lower than a first electric potential being a positive electrode potential corresponding to a negative electrode potential at which precipitation of lithium occurs, the electric potential lower than the first electric potential being a second electric potential and being higher than a positive electrode potential corresponding to an upper limit value of working voltages of the lithium-ion battery, and the apparatus includes a controller configured to perform recovery processing of changing the lithium precipitated on the negative electrode element into a lithium ion using the proton by using a power source section supplying a power to the lithium-ion battery to bring the positive electrode potential to the second electric potential.
