“…Despite having lower R CT , the overall resistance of recovered Si−G is still higher than purchased Si−G as the R SEI of purchased Si−G is 11.52 Ω while that of recovered Si−G is 18.72 Ω. The higher overall resistance of recovered Si−G before and after cycling could be due to polymeric remnants originating from the solar panel waste, akin to how a higher concentration of polymeric binder leads to higher overall resistance [39] …”

“…The higher overall resistance of recovered SiÀ G before and after cycling could be due to polymeric remnants originating from the solar panel waste, akin to how a higher concentration of polymeric binder leads to higher overall resistance. [39] Rate performance of both purchased SiÀ G and recovered SiÀ G were compared in which both electrodes were subjected to different fixed current rates ranging from 100 to 2000 mA g À 1 . At 100 mA g À 1 , purchased SiÀ G demonstrated higher specific capacity at 638.62 mAh g À 1 whereas recovered SiÀ G has lower specific capacity at 538.80 mAh g À 1 (Figure 6d).…”

The massive adoption of renewable energy especially photovoltaic (PVs) panels is expected to create a huge waste stream once they reach end-of-life (EoL). Despite having the highest embodied energy, present photovoltaic recycling neglects the high purity silicon found in the PV cell. Herein, a scalable and low energy process is developed to recover pristine silicon from EoL solar panel through a method which avoids energyintensive high temperature processes. The extracted silicon was upcycled to form lithium-ion battery anodes with performances comparable to as-purchased silicon. The anodes retained 87.5 % capacity after 200 cycles while maintaining high coulombic efficiency (> 99 %) at 0.5 A g À 1 charging rate. This simple and scalable process to upcycle EoL-solar panels into high value silicon-based anodes can narrow the gap towards a net-zero waste economy.

“…The results indicate that the composite with CMC‐SBR has relatively the highest sodium diffusion coefficient which facilitates the enhanced kinetic capability. The highest sodium diffusion coefficient for CMC‐SBR binder can be associated with the tortuosity, which is a significant factor because of its effect on the electrolyte conductivity [39] …”

“…The highest sodium diffusion coefficient for CMC-SBR binder can be associated with the tortuosity, which is a significant factor because of its effect on the electrolyte conductivity. [39] The galvanostatic discharge-charge test with PVdF, CMC-SBR, and Alginate were performed at 135 mA • g À 1 within the voltage window of 0.1-3.0 V in Figures 4a, 4b, and 4c, respectively. Samples with each binder can deliver initial discharge capacity of nearly 800 mAh • g À 1 , which are greater than the theoretical capacity of Se.…”

Factors affecting proper functioning of Na−Se system are investigated focusing on the polyselenide formation in ether‐ and carbonate‐based electrolytes. To do so, Se cathode is prepared by ball milling with commercial carbon and selenium powders. It is revealed that the soluble polyselenide species form in ether while no signature in carbonates proven by the in‐situ cyclic voltammetry and ex‐situ ultraviolet‐visible spectroscopy measurements as well as monitoring self‐discharge behaviours. Different Se discharge mechanism is also highlighted by staircase potentio electrochemical impedance spectroscopy (SPEIS) that is an impedance measurement applied to each potential step. Volume expansion is targeted using different types of binders in which carboxyl methylcellulose‐styrene butadiene rubber (CMC‐SBR) delivers the highest reversible capacity and the best rate performance resulting from its high adhesion strength. To further improve the performances, fluoroethylene carbonate (FEC) is used as a film forming additive that preserves Na metal integrity proven by the Na−Na symmetric cells and voltage relaxation upon cycling. As a whole, binders and electrolyte compositions are found to be the two crucial factors to obtain stable and high‐capacity Na−Se cells. This study underlines that much effort needs to be put on the strategies to overcome volume expansion than that of Se confinement into porous cathode.

The positive electrode of a Li-ion battery is made from active material, a binder and conductive material. In this work, the direct and interaction effects of these components on electrochemical performance of a Li-ion cell is studied using design of experiments. For this purpose, a two-level full factorial design was used and interactions were analyzed using analysis of variance. The content of carbon black and graphite as conductive materials and polyvinylidene difluoride as binder are considered as input parameters. Theactive material is NCM622 in the current work. Initial discharge capacity and Warburg coefficient obtained from impedance spectroscopy are output responses. Eleven experiments along with the central points were conducted to determine the relationship between process parameters and the output responses. This information is needed to optimize the output. It was observed that all three parameters are significant. In low carbon black and graphite content, the binder has a negative effect on both parameters, but in high levels of carbon black content it has a positive effect due to the better connectivity of carbon particles with each other. The results show that interaction of carbon black-binder and carbon black-graphite are also significant. Mathematical models were presented in order to optimize the parameters.
