Batteries with lithium metal anodes are promising because of lithium's high energy density. However, the growth Li dendrites on surface electrode in a liquid electrolyte during cycling reduces safety and cycle performance batteries, hindering their commercial application. In this work, we observe for first time smooth dendrite-free deposition vertically grown, self-aligned, highly compact columnar structure formed mixed carbonate–ether electrolyte. The stable microsized (∼10 μm diameter ∼20...
A battery consisting of a Li<sub>2</sub>S pre-lithiated material/cathode and Si–C anode shows both high energy density excellent capacity retention.
The high-voltage spinel LiNi0.5Mn1.5O4 cathode material suffers from the rapid degradation of electrochemical cycling performance at elevated temperatures, which prevents its successful commercialization. Herein, we show that coating surface this with Ta2O5, has high resistance against hydrofluoric acid (HF) attack, is an effective way to improve performance. A Ta2O5-coated half-cell shows a capacity retention ∼93% and Coulombic efficiency ∼98% after 100 cycles 55 °C, compared corresponding...
The accurate prediction of space target trajectories is critical for aerospace defense and situational awareness, yet it remains challenging due to complex nonlinear dynamics, measurement noise, environmental uncertainties. This study proposes a confidence-based dual-model fusion framework that separately processes linear trajectory components enhance accuracy robustness. Attention-Based Convolutional Long Short-Term Memory (AC-LSTM) network designed capture motion patterns by leveraging...
Spinel cathode materials (e.g., LiMn2O4 and LiNi0.5Mn1.5O4) with strongly bonded surface coatings are desirable for delivering improved electrochemical performance in long-term cycling. Here, we report that the introduction of bridging ions such as Fe Co, which can diffuse into both spinel Li3PO4, latter is found to cover form dense uniform particles (∼2-3 nm). Detailed structural analysis reveals 16c site structure ion-doped materials, contribute formation strong bonds between possibly via...
Polyethylene oxide-like polymers form in solid-electrolyte interphase films with the addition of polysulfide ions into a carbonate electrolyte.
Coating the surface of cathode materials with Li 3 PO 4 to improve cycling performance is commonly practiced; however, obtaining an effective and uniform coating on extremely difficult due lack strong bonds between them. Herein, this issue solved by LiNi 0.5 Mn 1.5 O via a novel hydrothermal method. It shown that can only be obtained introducing small amount additional metal ions, such as Co, in starting solution. X‐ray photoelectron microscopy combined scanning transmission electron reveals...
Infrared radiation characteristics are important for target detection and recognition. In this paper, a comprehensive calculation model is proposed midcourse targets. Firstly, the motion of built based on minimum energy trajectory theory. And then, thermal environment surface temperature analyzed calculated through node network method. At last, combining target's own with Sun Earth, method infrared tensity given. Some new results cone-shaped targets illustrate different coatings in light...
