Abstract Solid‐state lithium‐metal batteries with solid electrolytes are promising for next‐generation energy‐storage devices. However, it remains challenging to develop that both mechanically robust and strong against external mechanical load, due the brittleness of ceramic softness polymer electrolytes. Herein, a nacre‐inspired design ceramic/polymer composite “brick‐and‐mortar” microstructure is proposed. The nacre‐like electrolyte (NCPE) simultaneously possesses much higher fracture...
We present the first results of in situ scanning electron microscopy (SEM) an all-solid Li battery with a nickel–manganese–cobalt–oxide (NMC-622) cathode at 50 °C and operating voltage 2.7–4.3 V. Experiments were conducted under constant current several C rates (nC rate: cycling 1/n h): C/12, C/6, C/3. The microstructure evolution during was monitored by continuous secondary imaging. found that chemical degradation solid polymer electrolyte (SPE) main mechanism for failure. This observed...
Ultra-thick cathodes with a gradient pore structure and fast ion transport channels achieving high energy densities.
An important requirement of battery anodes is the processing step involving formation solid electrolyte interphase (SEI) in initial cycle, which consumes a significant portion active lithium ions. This more critical nanostructured with high specific capacity, such as Si and Sn, due to their surface area large volume change. Prelithiation presents viable approach address loss. However, stability prelithiation reagents big issue low potential chemical reactivity toward O2 moisture. Very...
Abstract Broadband electrochromism from visible to infrared wavelengths is attractive for applications like smart windows, thermal camouflage, and temperature control. In this work, the broadband electrochromic properties of Li 4 Ti 5 O 12 (LTO) its suitability camouflage thermoregulation are investigated. Upon + intercalation, LTO changes a wide bandgap semiconductor metal, causing nanoparticles on metal transition super‐broadband optical reflector solar absorber emitter. Large tunabilities...
Abstract Large‐area electrochromic devices (ECDs) based on a cathodically‐coloring, side chain‐modified poly(3,4‐ethylene dioxythiophene) (PEDOT) derivative and anodically‐coloring Prussian blue (PB) are assembled by customized sheet‐to‐sheet (S2S) lamination process. The ECDs with two complementary switching “half‐cells”, flexible PET‐ITO substrates, offer enhanced optical properties in terms of visible light transmission change (4–53%), contrast ratio (CR = 93.4) color neutrality (L* 77.9,...
