Abstract Carbon dots have been recognized as one of the most promising candidates for oxygen reduction reaction (ORR) in alkaline media. However, desired ORR performance metal–air batteries is often limited by moderate electrocatalytic activity and lack a method to realize good dispersion. To address these issues, herein biomass‐deriving reported achieve situ phosphorus doping (P‐doping) carbon their simultaneous decoration onto graphene matrix. The resultant product, namely P‐doped...
Metal fluorides usually have a large electronegativity and are promising electrode materials for high-power lithium-ion batteries. However, like other conversion-reaction-based materials, volumetric expansions capacity losses in cycling the major issues metal fluorides. Here, we explore substitution of Ni with Cu binary NiF2 its effects on electrochemical properties. By situ transmission electron microscopy, structural evolutions several ternary different Cu/Ni ratios observed correlated...
The energy density of lithium-ion batteries can be increased by replacing the traditional graphite anode with a high capacity silicon anode. However, volume changes and interfacial instabilities cause large irreversible continual loss lithium during cycling, which lead to rapid loss. In this work, we add Li 5 FeO 4 (LFO) LiNi 0.5 Mn 0.3 Co 0.2 O 2 (NMC) cathode as pre-lithiation additive, increases inventory extends cycle life Si-graphite/NMC full cells, decreases NMC particle degradation....
Copper (Cu) is a catalyst broadly used in industry for hydrogenation of carbon dioxide, which has broad implications environmental sustainability. An accurate understanding the degeneration behavior Cu catalysts under operando conditions critical uncovering failure mechanism and designing novel ones with optimized performance. Despite widespread use these materials, their mechanisms are not well understood because conventional characterization techniques lack necessary time spatial...
Heterostructuring of different transition metal dichalcogenides (TMDs) leads to interesting band alignment and performance improvement, thus enables new routes for the development materials next-generation semiconductor electronics.
Abstract This paper describes a new, high‐performance, Pb‐based nanocomposite anode material for lithium‐ion batteries. A unique structure of Pb@PbO core‐shell nanoparticles in carbon matrix is obtained by using simple high‐energy ball milling method the low‐cost starting materials PbO and black. Electrochemical performance tests show its excellent reversible capacity (≈600 mAh g −1 ) cycle stability (92% retention at 100th cycle), which are one best values reported anodes literature....
The tremendous growth in Li-ion batteries puts pressure on supply chains leading to the need invest recyclable processes. In article number 2005362, Eungje Lee, Seong-Min Bak, and co-workers synthesize a potentially lead-based anode (Pb anode) via high-energy ball-milling production of self-limiting oxide coated lead core embedded within carbon matrix. Electrochemical cycling performance is good, demonstrating 500 mAhg−1 with over 92% retention at 100 cycles.

This talk will describe a new, high-performance Pb-based nanocomposite anode material for lithium-ion batteries. A unique structure of core-shell Pb@PbO nanoparticles and carbon matrix was able to be obtained by simple high energy ball milling method using the low-cost PbO black starting materilas. The electrochemical performance tests showed excellent reversible capacity (ca. 600 mAh/g) cycle stability (92% retention at 100th cycle), which are best performances ever reported anodes in...
