Systems for recycling volatile battery sources
The invention is directed to systems and methods for the recycling of lithium ion batteries or the like. The system methods include comminution and destruction of used batteries, controlling the explosive reaction of the battery components during processing, and processing the materials into a suitable form for sampling and recycling.
1. A system for processing of electrical storage batteries having hazardous anode, cathode and electrolyte combinations for recycling comprising:
a) at least a first comminuting apparatus to receive batteries and cause exposure of the volatile components of batteries,
b) a neutralizing medium in which the processed materials from the at least first comminuting apparatus are disposed,
c) the at least first comminuting apparatus causing a size reduction of the materials to form a substantially homogenous particulate material, and
d) a sampling system to take at least one sample of the substantially homogenous material after neutralization in the neutralizing medium to assess the components of the material.
2. The system of claim 1 , further comprising at least a second comminuting apparatus receiving the material from the neutralizing medium container to form the substantially homogenous material.
3. The system of claim 1 , further comprising a screening system to receive the comminuted material and to form the homogenous material having a predetermined size distribution.
4. The system of claim 1 , further comprising at least one sensor to detect when the materials are substantially neutralized.
5. The system of claim 1 , further comprising a scrubbing system to receive the volatile components generated from the comminuted material.
6. The system of claim 5 , wherein the scrubbing system uses an alkaline scrub solution and filters, with any discharge materials from the comminuted material scrubbed and any washing solutions captured and cleaned for reuse.
7. The system of claim 1 , wherein the neutralizing medium is about a six percent brine solution.
8. The system of claim 1 , further comprising a drying system to dry the comminuted material after being disposed in the neutralizing medium.
9. The system of claim 1 , wherein the sampling system automatically takes samples from the stream of processed material as it is created.
10. The system of claim 1 , further comprising a gas evacuation/scrubbing system to receive outgassing from the comminuted material.
11. The system of claim 1 , wherein first and second comminuting apparatus are provided for comminution of the batteries prior to and after being disposed in the neutralizing medium.
12. A system for processing of electrical storage batteries having hazardous anode, cathode and electrolyte combinations for recycling comprising:
a) at least a first comminuting apparatus to cause exposure of the volatile components of batteries,
b) a reaction chamber in which the processed materials from the at least first comminuting apparatus are disposed,
c) the at least first comminuting apparatus causing a size reduction of the materials to form a substantially homogenous particulate material, and
d) a sampling system to take at least one sample of the substantially homogenous material after neutralization in the neutralizing medium to assess the components of the material.
13. The system of claim 12 , further comprising a gas evacuation/scrubbing system to receive outgassing from the comminuted material.
