The known method is difficult to apply to a used lithium secondary battery.

This is a method of recovering valuable materials from used lithium secondary batteries.

５０℃以上、より好ましくは５００℃以上である。上限
は１０００℃で充分である。In the present invention, first, the used lithium secondary battery is roasted. This roasting is performed using a mixture of the active material and the binder, such as porous polypropylene used for the separator, lithium hexafluorophosphate that is the electrolyte component, polyvinylidene fluoride that is the binder of the active material, and the like. It is performed to decompose, burn or volatilize an organic material such as N-methyl-2-pyrrolidone, which is a solvent, to remove it. The roasting temperature is preferably 3
The temperature is 50 ° C or higher, more preferably 500 ° C or higher. An upper limit of 1000 ° C is sufficient.

砕には、周知の衝撃、摩擦、せん断、圧縮を単独又は組
み合わせて利用する破砕装置が適宜使用できる。Next, the roasted product is crushed. This crushing is performed by removing the binder and the solvent by the above-mentioned roasting, and a valuable material that is very likely to become powder particles, and an aluminum foil used as a positive electrode current collector that is relatively less crushable than this valuable material. This is because it is easy to separate the copper net, the copper foil or the like used as the negative electrode current collector and the cylindrical outer can made of iron in the subsequent sieving step. For crushing, valuable materials are JIS Z 8801
It is preferable to carry out so that the particle size of the standard sieve is less than 3360 μm. If the particle size is larger than 3360 μm, the quality of valuable metal under the sieve obtained in the subsequent sieving step is deteriorated. For the crushing, a known crushing device that uses impact, friction, shearing, or compression alone or in combination can be appropriately used.

A sieve having a size of 60 μm or less may be appropriately selected. Too fine a sieve reduces the recovery of valuable metals. The lower limit of the size of the sieve is preferably 420 μm.
