A triethylene glycol-based 1,2,3-triazolate lithium salt with ionic liquid properties at room temperature is synthesized in three steps including copper-catalysed cycloaddition between alkyne-functionalized monomethoxy-triethylene glycol and azidomethyl pivalate, followed by the deprotection of the methyl pivalate group and further lithiation of the 1H-1,2,3-triazole intermediate. The resulting lithium 1,2,3-triazolate is characterized by NMR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, broadband dielectric spectroscopy, electrochemical impedance spectroscopy and cyclic voltamperometry. This approach provides new opportunities for the further development of highly functional molecular and macromolecular lithium salts.

Electrochromic (EC) materials based on ion insertion/desertion mechanisms provide a possibility for energy storage. Solution-processable energy storage EC polyamides have great potential for use in smart displays and EC supercapacitors. A suitable monomer structure design is particularly important for enhancing the electrochemical properties of polyamides.

Wet-crushing with aqueous media protection is considered safer and more efficient than common inert-gas protected dry-crushing in preprocessing spent lithium-ion batteries (LIBs). However, it is also accompanied with the releasement and transformation of hazardous electrolyte, while the mechanisms and pollution impact yet remain unknown. Based on a self-built wet-crushing system, this topic was systematically investigated here.

The recovery of valuable materials from spent lithium-ion batteries (LIBs) has experienced increasing demand in recent years. Current recycling technologies are typically energy-intensive and are often plagued by high operation costs, low processing efficiency, and environmental pollution concerns. In this study, an efficient and environmentally friendly dielectrophoresis (DEP)-based approach is proposed to separate the main components of "black mass" mixtures from LIBs, specifically lithium iron phosphate (LFP) and graphite, based on their polarizability differences.

Electroconvulsive therapy (ECT) is widely recognized as a safe and effective intervention for treating severe affective episodes in patients with bipolar disorder. However, it can sometimes precipitate unexpected manic phases in patients treated for a depressive episode, a phenomenon known as ECT-induced mania. While this occurrence is recognized, it remains poorly understood and minimally addressed in the literature.
