Aqueous lithium‐ion batteries offer promising advantages such as low cost, enhanced safety, high rate capability, and the ability to deliver considerable capacity at 1.8 V, making them ideal candidates for large‐scale reserve power sources for renewable energy. However, the practical application of aqueous lithium‐ion batteries has been hindered by the poor cycle stability of layered cathode materials, including LiCoO2, in neutral aqueous electrolytes. This review examines the working principles, material limitations, and research progress of aqueous lithium‐ion batteries. The types and characteristics of materials used in the cathode of aqueous lithium‐ion batteries are summarized, with a primary focus on the attenuation mechanisms of LiCoO2 when used as the cathode material in aqueous electrolytes. Furthermore, this review explores the advancements in utilizing LiCoO2 in the cathode of aqueous lithium‐ion batteries, as well as the combination with machine learning. By addressing these critical aspects, this review aims to provide a comprehensive understanding of aqueous lithium‐ion batteries and shed light on future development and application prospects.

Objective: Dichlorodiphenyldichloroethylene (DDE), an obesogen accumulating in adipose tissue, is released into circulation with weight loss, although its impact is underexplored among adolescents. We tested the association using an integrative translational approach of epidemiological analysis among adolescents with obesity and in vitro measures exploring the impact of DDE on adipogenesis via preadipocytes. Methods: We included 63 participants from the Teen‐Longitudinal Assessment of Bariatric Surgery (Teen‐LABS) cohort. We assessed 4,4′‐DDE in visceral adipose tissue at surgery and BMI and waist circumference at surgery and 0.5, 1, 3, and 5 years after. We conducted longitudinal analysis to estimate the interaction on weight loss between DDE and time since surgery. In vitro analysis quantified adipogenic differentiation in commercial human preadipocytes exposed to 4,4′‐DDE via fluorescent staining and imaging. Results: A dose–response relationship was observed, with the low‐exposure group having a greater reduction in BMI during the first year compared to higher‐exposure groups and showing smaller regains compared to higher‐exposure groups after the first year. In vitro analysis of preadipocytes treated with 4,4′‐DDE during adipogenic differentiation for 12 days showed a concentration‐dependent increase in lipid accumulation. Conclusions: DDE could contribute to weight trajectory among adolescents undergoing bariatric surgery, potentially mediated via promoted adipogenesis in preadipocytes. [ABSTRACT FROM AUTHOR]

Improving the charge separation and transport efficiency at semiconductor‐electrolyte interface is critical for high‐performance photoelectrochemical (PEC) water‐splitting devices. Here, the core‐shell‐structured Ni@Co nanoislands were electrodeposited onto the surface of n‐type Si photoanode to construct a metal‐insulator‐semiconductor (MIS) structure. We discover that the high‐quality interface in Si/SiOx/Ni MIS structure is more efficient for charge extraction and transfer than Si/SiOx/Co. Owing to a slightly higher work function for Co (5.0 eV) than Ni (4.6 eV), the Si/SiOx/Ni@Co exhibits the larger band bending to enhance the charge separation efficiency, while the in‐situ formed CoOOH significantly increases the charge injection efficiency due to the decreased oxygen‐evolution overpotentials. As a result, the Ni@Co core‐shell nanoparticles coupling with n‐Si photoanode can afford the PEC performance with an onset potential of 1.02 V versus reversible hydrogen electrode (RHE), saturated current density of 36.7 mA cm−2, and retain good stability in K‐borate buffer solution. This core‐shell structure strategy is efficient and easy to achieve the separation of photogenerated carriers and improve the charge injection efficiency to nearly 100 % She sells core shells: Core‐shell Ni@Co nanoparticles were synthesized on n‐type Si substrate with an island distribution. In this photoanode, Ni has good contact with Si and forms a MIS structure as high‐function metal core, enabling effective photogenerated carriers separation. And the amorphous Co shell with higher work‐function than Ni core could remarkably improve the charge injection efficiency. Therefore, this device achieves high activity in water oxidation to 10.65 mA cm−2 at 1.23 VRHE and 36.7 mA cm−2 at 1.8 VRHE. [ABSTRACT FROM AUTHOR]
