Disassembly of battery

A method for processing spent energy storage and conversion devices for recycling, comprising:

• obtaining a spent energy storage and conversion device that comprises packaging containing one or more cells, where each cell in the one or more cells comprises a container containing a plurality of cell components, the plurality of cell components including a positive electrode material and a negative electrode material;
• and
• disassembling the spent energy storage and conversion device, where disassembling each spent energy storage and conversion device comprises:
• opening the packaging of the spent energy storage and conversion device to expose at least a portion of the one or more cells of the spent energy storage and conversion device;
• discharging the one or more cells of the spent energy storage and conversion device;
• separating the one or more cells from the packaging to yield one or more individual cells;
• and
• disassembling each cell in the one or more individual cells, where disassembling each cell comprises:
• cutting the container of the cell;
• separating the container from the plurality of cell components;
• and
• separating the positive and negative electrode materials.
