Special Issue Information

Dear Colleagues,

This Special Issue includes papers on recent advances in multifunctional binders for Li-ion batteries. Li-ion battery technology has improved significantly over the last decade, thanks to the developments in the materials, engineering design and manufacturing of batteries. One of the critical components of Li-ion batteries is the binder that holds the active particles and inactive conductive additives of the composite electrodes in contact with each other and with the current collector. An ideal binder should be mechanically robust to withstand the contraction and expansion of the electrodes during Li de/-intercalation, and chemically inert to solvents used in electrolytes. The demand for higher capacity batteries requires complete or partial replacement of graphite with alloy anodes (i.e., Si, Sn, etc.) that have significantly higher volume expansion during Li intercalation. As a result, more mechanically robust binders are needed in the future. Additionally, developing conductive binders can reduce the need for adding inactive conductive additives to the composite electrodes, and can slow the degradation of a battery. In this Special Issue, recent developments in multifunctional binders that are mechanically robust, chemically inert and electrically conductive are discussed. Papers invited to this Special Issue were subject to a rigorous peer review procedure with the aim of the rapid and wide dissemination of research results, developments and applications

The recovery of cathode and anode materials plays an important role in the recycling process of spent lithium-ion batteries (LIBs). Organic binders reduce the liberation efficiency and flotation efficiency of electrode materials derived from spent LIBs. In this study, pyrolysis technology is used to improve the recovery of cathode and anode materials from spent LIBs by removing organic binders. Pyrolysis characteristics of organics in electrode materials are investigated, and on this basis, the effects of pyrolysis parameters on the liberation efficiency of electrode materials are studied. Afterwards, flotation technology is used to separate cathode material from anode material. The results indicate that the optimum liberation efficiency of electrode materials is obtained at a pyrolysis temperature of 500 °C, a pyrolysis time of 15 min and a pyrolysis heating rate of 10 °C/min. At this time, the liberation efficiency of cathode materials is 98.23% and the liberation efficiency of anode materials is 98.89%. Phase characteristics of electrode materials cannot be changed under these pyrolysis conditions. Ultrasonic cleaning was used to remove pyrolytic residues to further improve the flotation efficiency of electrode materials. The cathode material grade was up to 93.89% with a recovery of 96.88% in the flotation process. Full article
