Electrolyte filling and wetting is a quality-critical and cost-intensive process step of battery cell production. Due to the importance of this process, a steadily increasing number of publications is emerging for its different influences and factors. We conducted a systematic literature review to identify common parameters that influence wetting behavior in experimental settings, specifically focusing on material, processes, and experimental measurement methods but excluding simulation studies. We reduced the initially found 544 records systematically to 39 fully labeled articles. Our profound analysis guided by attributed labelings revealed current research gaps such as the lack of a holistic view on measurement methods for filling and wetting, underrepresented studies relevant to series production, as well as the negligence of research targeting the transferability of results from the material to the cell level, while also examining the measured variables’ interactions. After comparatively illustrating and discussing implications of our findings, we also discussed limitations of our contribution and suggested ideas for potential further research topics.

This research addresses the performance and degradation characteristics of lithium-ion batteries (LIBs), focusing on the implications of electrolyte depletion and gas bubble entrapment within the cell. Using a comprehensive electrochemical-thermal model, this study provides simulation results of electrolyte depletion and gas bubble entrapment and their influence on the lifespan of lithium-ion batteries (LIBs). Th study notably explores the battery life beyond the critical “knee-point” - a transition point marking the shift from linear to accelerated capacity decline. An intricate exploration of the relationship between electrolyte saturation levels and various battery parameters, including performance, thermal behavior, and transport properties, is carried out through a detailed mathematical model. The findings highlight the critical impact of electrolyte levels on LIB performance and thermal behavior. It also shows that electrolyte depletion can facilitate lithium plating. Providing insights into electrolyte depletion and gas production processes paves the way for strategies to enhance battery life, safety, and performance, ultimately fostering a deeper understanding of LIB degradation mechanisms.

“…As a kind of novel green solvent, ionic liquids (ILs) have attracted much attention due to their unique properties (negligible volatility, high thermal stability, structural variation, and excellent affinity to acidic gas, etc.). The research of ILs mainly focused on catalytic synthesis [9][10][11][12][13][14] , energy [15][16][17] , solvents [18][19][20][21][22] , materials [23][24][25][26] , etc. Protic ionic liquids (PILs) are a class of cost-effective ILs for the removal of acidic gas, which can be easily prepared from simple materials through the direct neutralization between the corresponding acid and base.…”

The resource utilization of hydrogen sulfide (H2S) is an important and promising topic in energy chemical engineering. The previous products developed in our group through H2S conversion are sulfur or mercaptan acids. Alternative way to convert H2S is still desirable. Herein, we developed a green and mild method to convert H2S into mercaptan alcohols by the addition reaction with epoxide mediated in tertiary amine-functionalized protic ionic liquids (PILs). Reaction kinetics, substrate scope, and regeneration experiment have all been explored. Almost quantitative conversion of substrates was realized with catalytic loading of PILs at 30 C. Water extraction was used to recycle the catalysts from the reaction system. It is believed that the excellent results, together with its operational simplicity and the ability to successively reuse the catalyst, make this new methodology environmentally benign and cost-effective. The generality of the H2S resource methodology gives it potential for application on an industrial scale.
