Embodiments described herein relate to methods of recycling battery waste. In some aspects, a method can include applying a first heat treatment at a temperature of between about 100° C. and about 700° C. to the battery waste, the first heat treatment decomposing at least about 80 wt % of the binder, separating the electrode material from the current collector, and applying a second heat treatment at a temperature between about 400° C. and about 1,200° C. to the electrode material to produce a regenerated electrode material, the second heat treatment decomposing at least 90 wt % of binder remaining in the electrode material to produce a regenerated electrode material. In some embodiments, the method can include applying a surface treatment to the electrode material to remove surface coatings and/or surface impurities from the electrode material. In some embodiments, the surface treatment can include applying a solvent to the electrode material.

Methods and systems for scalable direct recycling of battery waste

A method includes processing at least one battery into a plurality of core sections. Each core section in the plurality of core sections includes an anode section, a cathode section including a cathode material, a separator section disposed between the anode section and the cathode section, and an electrolyte. The method also includes disposing the plurality of core sections into a solvent so as to produce a mixture of cathode materials from the plurality of core sections. The solvent and the electrolyte form an ionic conductive medium, and the mixture of the cathode materials is characterized by a substantially homogeneous distribution of an active element in the cathode material.

Methods and systems for scalable direct recycling of batteries

To simulate the appearance of weathered wood, newer wood is treated with a compound that includes the combination of a first part of an oil-type carrier, a second part of rotten stone and a third part of wax. A surface of the wood is first subjected to a blackening procedure as by burning or dipping in a suitable stain. The surface is then treated with the compound. Thereafter, highlights are developed in the surface by scraping and/or buffing. A somewhat less-aged look also is obtained by suitably staining rough-sawed lumber.
