Abstract All-solid-state lithium-based batteries with inorganic solid electrolytes are considered a viable option for electrochemical energy storage applications. However, the application of lithium metal is hindered by issues associated growth mossy and dendritic Li morphologies upon prolonged cell cycling undesired reactions at electrode/solid electrolyte interface. In this context, alloy materials such as lithium-indium (Li-In) alloys widely used laboratory scale because their...
There has been increasing interest in the emerging ionic thermoelectric materials with huge thermopower. However, it's challenging to selectively tune thermopower of all-solid-state polymer because transportation ions polymers is much more complex than those liquid-dominated gels. Herein, this work provides a wide tunable range (+20~-6 mV K-1), which different from previously reported Moreover, mechanism p-n conversion material at atomic scale was presented based on analysis Eastman entropy...
Abstract The giant thermopower of ionic thermoelectric materials has attracted great attention for waste-heat recovery technologies. However, generating cyclic power by modules remains challenging, since the ions cannot travel across electrode interface.

Meanwhile, promising generator was proposed achieve generation under constant heat course only switching external...
Abstract Macroscopic fibres assembled from two-dimensional (2D) nanosheets are new and impressing type of fibre materials besides those one-dimensional (1D) polymers, such as graphene fibres. However, the preparation property-enhancing technologies these follow 1D polymers by improving orientation along axis, leading to non-optimized microstructures low integrated performances. Here, we show a concept bidirectionally promoting assembly order, making achieve synergistically improved...

A stable electrode–electrolyte interface is the key for application of high-energy all-solid-state lithium metal batteries, but nanoscale behavior remains mysterious. Herein, utilizing cryogenic transmission electron microscopy, we investigate nanostructure interphase layer between a single Li dendrite and sulfide electrolyte (SE) at various temperatures. It found that single-crystal Li2S with ∼12 nm thickness formed 25 °C good passivation on interface, while 60 °C, composed polycrystalline...
Abstract The formation of lithium dendrites severely hinders the practical application all‐solid‐state metal batteries (ASSLMBs). conventional view is that initiate at anode and then grow into solid electrolytes (SEs), while a recent popular opinion holds Li + ions can directly be reduced grain boundaries (GBs) within electrolytes, these internal interconnect resulting in short‐circuit failure. However, whether GBs or interface dominates dendrite initiation still under debate. Herein,...
Abstract Thermoelectrics converting heat and electricity directly attract broad attentions. To enhance the thermoelectric figure of merit, zT , one key points is to decouple carrier-phonon transport.
