A battery managing apparatus according to one embodiment of the present disclosure includes: a profile acquisition unit configured to obtain a battery profile representing the relationship between voltage and capacity of the battery; a profile determination unit configured to adjust a preset reference positive electrode profile and reference negative electrode profile to correspond to the battery profile and determine the positive electrode profile and negative electrode profile of the battery; and a control unit configured to calculate the lithium loss rate of the battery based on the positive electrode profile, calculate the negative electrode side-reaction rate of the battery based on the battery profile, and calculate the positive electrode side-reaction rate of the battery based on the lithium loss rate and the negative electrode side-reaction rate.

Battery managing apparatus and method thereof

Provided are a reuse method of electrode scrap and a method of fabricating a recycled electrode using the same. The reuse method of electrode scrap of the present disclosure includes (a) dry milling electrode scrap remaining after punching an electrode sheet including an active material layer on a current collector to obtain milled products; and (b) screening active material layer flakes from current collector fragments in the milled products by sieving the milled products, and collecting the screened active material layer flakes to obtain reusable particles.

Method for recycling electrode scraps, and method for manufacturing electrode by using same
