Mimicking Capacity Degradation in a Lithium Ion Battery Anode in Cells With a Li Metal Electrode: A Perspective on Advantages

Advanced Energy & Sustainability Research
The lifetime of Li‐ion batteries (LIB) depends on the amount of Li ions and electrons (= active Li), definingLi inventory and cell capacity and can be limited by active Li loss (ALL) at the negative electrode (= anode), e.g., via electrolyte reduction ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
