Embodiment Construction

[0011] The term "battery" is used herein to refer to an electrochemical primary cell, which includes an anode, a cathode, and an intermediate electrolyte. It also applies to a plurality of such cells arranged in parallel and / or in series and sharing the same enclosure.

[0012] figure 1 An example method 100 is shown for recycling batteries with alkaline (pH>7) electrolytes. Such example batteries may include common alkaline batteries (eg, AA, AAA, C, and D batteries), nickel metal hydride (NiMH) batteries, and various types of multi-cell battery packs. Such batteries may contain water, hydroxide-based electrolytes: including, for example, Group IA hydroxides (eg, LiOH) or quaternary ammonium hydroxides (eg, tetra-n-butylammonium hydroxide). This battery pack can be used to power consumer electronics (cameras, mobile phones, computers, etc.), portable electronics (tools, toothbrushes, vacuum cleaners, etc.) and vehicles (electric bicycles, hybrid and pure electric vehicles, ...

Abstract

The invention discloses an embodiment about recycling alkaline batteries. In one disclosed embodiment, a method of recycling a battery having an alkaline electrolyte includes rupturing the battery under anaerobic conditions and flooding the interior of the battery with carbon dioxide in an oxygen-free chamber.

Description

technical field [0001] This application relates to the fields of storage-battery recycling and metal recovery. Background technique [0002] Every battery has a finite life cycle beyond which its ability to store and deliver charge is significantly reduced. The life cycle of a modern rechargeable battery (eg, a nickel metal hydride (NiMH) battery) can include hundreds of charge / discharge cycles, whereas a typical alkaline battery has only one discharge cycle. At the end of the life cycle, although chemical and structural changes have reduced their ability to store and transport charge, the material composition of the battery remains. Recycling batteries at this stage can provide economical, safety-related and environmental benefits. [0003] This benefit may arise from the fact that recycling at least some of the battery material components (especially metals) would be cheaper and have less environmental disturbance than obtaining them from raw materials. Additionally, so...
