Lithium ion battery control device and lithium ion battery recovery method

摘要

An object of the present invention is to return lithium deposited to lithium ions without applying a large heat load. A control device for a lithium ion battery in which a power generation element including a positive electrode body and a negative electrode body is housed in a case, wherein the case has a positive electrode potential corresponding to a negative electrode potential causing lithium deposition. In the second potential lower than 1 and higher than the positive electrode potential corresponding to the upper limit value of the operating voltage of the lithium ion battery, a compound that generates protons by emitting electrons to the positive electrode body is accommodated. And by driving a power supply unit that supplies power to the lithium ion battery and setting the positive electrode potential to the second potential, the lithium deposited on the negative electrode body using the protons is converted into lithium ions. A controller for a lithium ion battery, comprising a controller for executing a recovery process. [Selection] Figure 6
