Silicon anode solid-state batteries Research on has focused lithium metal anodes. Alloy-based anodes have received less attention in part due to their lower specific capacity even though they should be safer. Tan et al . developed a slurry-based approach create films from micrometer-scale silicon particles that can used with carbon binders. When incorporated into batteries, showed good performance across range of temperatures and excellent cycle life full cells. —MSL
Lithium metal has been considered the "holy grail" anode material for rechargeable batteries despite fact that its dendritic growth and low Coulombic efficiency (CE) have crippled practical use decades. Its high chemical reactivity stability make it difficult to explore intrinsic physical properties of electrochemically deposited lithium (EDLi) accompanying solid electrolyte interphase (SEI). To prevent enhance electrochemical reversibility, is crucial understand nano- mesostructures EDLi....
A non-flammable ionic liquid-ether based hybrid electrolyte shows a robust Li deposition morphology and very stable cycling of NMC|Li metal cell facilitated by beneficial interphase formation at the anode surface.
Sulfurized polyacrylonitrile (SPAN) represents a class of sulfur-bonded polymers, which have shown thousands stable cycles as cathode in lithium-sulfur batteries. However, the exact molecular structure and its electrochemical reaction mechanism remain unclear. Most significantly, SPAN shows an over 25% 1st cycle irreversible capacity loss before exhibiting perfect reversibility for subsequent cycles. Here, with thin-film platform array analytical tools, we show that is associated...
Sodium-ion batteries exhibit significant promise as a viable alternative to current lithium-ion technologies owing their sustainability, low cost per energy density, reliability, and safety.
Abstract Spinel‐type LiNi 0.5 Mn 1.5 O 4 (LNMO) is one of the most promising 5 V‐class cathode materials for Li‐ion batteries that can achieve high energy density and low production costs. However, in liquid electrolyte cells, voltage causes continuous cell degradation through oxidative decomposition carbonate‐based electrolytes. In contrast, some solid‐state electrolytes have a wide electrochemical stability range withstand required potential. this work, thin‐film battery consisting an LNMO...
Abstract The practical application of lithium (Li) metal anode (LMA) is still hindered by non‐uniformity solid electrolyte interphase (SEI), formation “dead” Li, and continuous consumption although LMA has an ultrahigh theoretical specific capacity a very low electrochemical redox potential. Herein, facile protection strategy reported for using double layer (DL) coating that consists polyethylene oxide (PEO)‐based bottom highly stable with promotes uniform ion flux, cross‐linked...
Lithium metal anodes are crucial for high-energy-density batteries, but concerns regarding their safety remain. Limited investigations have evaluated the reactivity of Li in full cell configurations. In this study, differential scanning calorimetry (DSC) and situ Fourier-transform infrared spectroscopy (FTIR) were employed to quantitatively examine reactivity. Lithiated graphite (Li-Gr) lithiated silicon (Li-Si) also compared. The plated was systematically investigated when combined with...
Silicon with a high theoretical capacity (3,579 mAh/g) is promising anode candidate for lithium-ion batteries. However, commercialization still impeded by low Coulombic efficiency, caused solid electrolyte interphase (SEI) formation and trapped lithium (Li)-silicon (Si) alloy during repeated volume change. Quantifying losses from each factor crucial to formulate rational design strategies further improvement. In this work, titration-gas chromatography cryogenic transmission electron...
Abstract The lithium metal anode is essential for next‐generation high‐energy‐density rechargeable Li‐metal batteries. Although extensive studies have been performed to prolong the cycle life of batteries, calendar life, which associates with chemical corrosion Li in liquid electrolytes, has not quantitatively understood. Here, by combing titration gas chromatography method and cryogenic focused ion beam, a quantitative relationship between rate electrochemically deposited morphology various...
Solid-state lithium batteries are uniquely suited for operation at elevated to even high temperatures (>100 °C). Under these conditions, however, oxide cathode materials unstable with high-conductivity sulfide-based electrolytes while elemental sulfur suffers from poor utilization due its insulating nature. Here, we developed an ionic liquid mediated synthesis procedure polythiocynogen (poly-SCN) and applied it as a sulfur-rich cathode. The material, uniform, submicrometer particle size > 55...
Lithium (Li) metal anodes are essential for developing next-generation high-energy-density batteries. However, Li dendrite/whisker formation caused short-circuiting issue and short cycle life have prevented lithium from being viably used in rechargeable Numerous works been done to study how regulate the growth electrochemical cycling by using external stacking forces. While it is widely agreed that stack pressure positively affects plating/stripping process, optimized range provided...
