Abstract
Official abstract text for this publication.
A separation and extraction method includes immersing a battery in water comprising sodium chloride and a polypeptide. The sodium chloride can facilitate discharge of the battery and the polypeptide can collect substances from the battery. After the battery is taken out of the water, the method may further include pulverizing the battery, sorting metal materials from the pulverized battery; and re-immersing the sorted metal material in the water.
First claim
Opening claim text (preview).
The invention claimed is: 1. A separation and extraction method comprising: immersing a battery in a solution comprising sodium chloride and a polypeptide; facilitating, by the sodium chloride, discharge of the battery while collecting, by the polypeptide, substances released from the battery; separating and extracting the substances as suspended matters on the solution surface, precipitates in the solution and sediments in the solution; and collecting hydrogen fluoride generated by the immersing the battery in the solution. 2. The separation and extraction method according to claim 1 , further comprising: pulverizing the battery taken out of the solution after the immersing; sorting metal material from the pulverized battery; and re-immersing the sorted metal material in the solution comprising the polypeptide. 3. The separation and extraction method according to claim 1 , wherein the polypeptide is polyglutamic acid.
