| | Harvesting |
| | Abstract | Battery is an electrochemical cell for providing electric power as |
| | needed, and rechargeable battery is a secondary cell that can store |
| | excess energy from renewable energy sources. Based on a study |
| | performed by Navigant Research, the worldwide revenue of one |
| | common type of rechargeable batteries, Lithium-ion (Li-ion) cells, is |
| | expected to reach $26 billion US dollars in 2023 due to its wide |
| | applications. However, there have been numerous concerns with |
| | respect to the availability of Lithium, an element crucial to the |
| | production of Li-on batteries. The current processing activities at |
| | recycling facilities are limited to the cell destruction for recovering |
| | chemical elements in batteries with three shortcomings: a) restricted |
| | accessibility: only few facilities available worldwide for element recovery; |
| | b) economic non-viability: element recovery cost higher than mining |
| | the elements; and c) waste of resources: undifferentiated destruction of |
| | both good and bad cells. |
| | |
| | In this project I uncovered a brand-new method that can be used to sort |
| | 18650 Li-ion batteries in large quantity and in real time for harvesting |
| | used cells with enough capacity for battery reuse. After a large number |
| | (about 170) of battery cells were collected from a battery recycling |
| | facility, internal resistance and capacity tests of these cells were |
| | conducted as a reference point for comparison with a novel |
| | degradation-based method based on X-ray radiographic scanning and |
| | digital image contrast computation. The test results indicate that the |
| | sorting accuracy of test cells is about 81% with composite indices and |
| | 87% with machine learning. The execution time of my algorithm is at a |
| | level of 100 milliseconds, making the method a real-time solution for |
| | harvesting the remaining energy in good used cells with a potential |
| | multi-million-dollar market. This method will potentially be a |
| | breakthrough to the lithium battery recycling process and the energy |
| | conservation of our eco-system through the sorting process that |
| | reduces the need to produce new Li-ion batteries. |
