Systems and methods for electrochemical cell material recycling

This invention describes a step-by-step process for taking apart used batteries to recover valuable materials from their positive electrodes (cathodes). It involves carefully dismantling the battery, cutting open individual cells, and then using sound waves in a liquid bath to separate the active cathode material from its metal backing. This recovered material is then dried and can be used to make new battery cathodes.

Why it matters: Filed before recent improvements in industrial ultrasonic technology could make this specific cathode material separation method more energy-efficient or cost-effective.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedUltrasonic probe, solvent baths, material handling equipment
