Description
This study explores the reuse of notebook battery cells in off-grid, or autonomous, photovoltaic systems, emphasizing the economic and environmental viability of this practice. The selection criterion, based on the cell charge capacity (Ccel ≥ 2000 mAh), has been shown to be robust, enabling the efficient use of these cells in batteries for off-grid systems. The cost analysis compared the assembly of batteries using reused and new cells, demonstrating the economic advantage of the former. Furthermore, the finding that about half of the 18650 cells discarded by notebook users are still usable highlights both the environmental value and the sustainability of this practice.
The study also underscores the importance of considering the entire life cycle of materials used in autonomous photovoltaic systems, aiming for a more sustainable and efficient approach. Incorporating reused 18650 cells not only reduces costs but also helps decrease electronic waste and utilizes resources already available in the market.
The results presented in this work provide valuable insights for the implementation of off-grid photovoltaic systems using reused notebook battery cells. The economic, environmental, and technical implications are discussed in detail, paving the way for future research and developments in this area. Reusing notebook battery cells appears as a promising solution to enhance the accessibility and sustainability of off-grid photovoltaic systems, aligning with the principles of a circular economy and efficient resource use.
