Fast charging lithium (Li)‐ion batteries are intensively pursued for next‐generation energy storage devices, whose electrochemical performance is largely determined by their constituent electrode materials. While nanosizing of electrode materials enhances high‐rate capability in academic research, it presents practical limitations like volumetric packing density and high synthetic cost. As an alternative...
The performance of zinc‐ion batteries is severely hindered by the uncontrolled growth of dendrites and the severe side reactions on the zinc anode interface. To address these challenges, a weak‐water‐coordination electrolyte is realized in a peptone‐ZnSO4‐based electrolyte to simultaneously regulate the solvation structure and the interfacial environment. The peptone molecules have stronger interaction...
Low Coulombic efficiency, low‐capacity retention, and short cycle life are the primary challenges faced by various metal‐ion batteries due to the loss of corresponding active metal. Practically, these issues can be significantly ameliorated by compensating for the loss of active metals using pre‐metallization techniques. Herein, the state‐of‐the‐art development in various pr‐emetallization techniques...
Real‐time observation of the electrochemical mechanistic behavior at various scales offers new insightful information to improve the performance of lithium‐ion batteries (LIBs). As complementary to the X‐ray‐based techniques and electron microscopy‐based methodologies, neutron scattering provides additional and unique advantages in materials research, owing to the different interactions with atomic...
Current lithium‐ion battery technology is approaching the theoretical energy density limitation, which is challenged by the increasing requirements of ever‐growing energy storage market of electric vehicles, hybrid electric vehicles, and portable electronic devices. Although great progresses are made on tailoring the electrode materials from methodology to mechanism to meet the practical demands,...
Electrodes Design for Lithium Batteries
Sluggish mass transport and charge transfer dynamics are the main bottlenecks with increasing the mass loading multiple times to commercial level. Thus, in article number 2102233, Hongchao Liu, Mingzheng Ge, Yuxin Tang, and co‐workers review the state‐of‐the‐art developments on constructing commercialization‐driven high‐capacity electrodes with high mass loading,...
As one of the most efficient electrochemical energy storage devices, the energy density of lithium‐ion batteries (LIBs) has been extensively improved in the past several decades. However, with increased energy density, the safety risk of LIBs becomes higher too. The frequently occurred battery accidents worldwide remind us that safeness is a crucial requirement for LIBs, especially in environments...
Silicon anode with extremely high theoretical specific capacity (≈4200 mAh g−1), experiences huge volume changes during Li‐ion insertion and extraction, causing mechanical fracture of Si particles and the growth of a solid–electrolyte interface (SEI), which results in a rapid capacity fading of Si electrodes. Herein, a mechanically reinforced localized structure is designed for carbon‐coated Si nanoparticles...
In article number 2002094, Yuxin Tang, Yuekun Lai, Xiaodong Chen, and co‐workers report a mechanically reinforced localized structure with ultralong titania nanotubes to alleviate the mechanical strain and stabilize the solid–electrolyte interface layer for silicon‐based anode materials, delivering low electrode thickness swelling and excellent cycling performance.
In article number 1907029, Jianying Huang, Jun Hu, Yuekun Lai, Yuxin Tang, and co‐workers reveal a correlation between the oxygen evolution reaction overpotential and the cobalt‐based electrode composition in an electrospinning “Microparticles‐in‐Spider Web” superstructure electrode, leading to remarkable electrocatalytic activity.
Sluggish kinetics of the multielectron transfer process is still a bottleneck for efficient oxygen evolution reaction (OER) activity, and the reduction of reaction overpotential is crucial to boost reaction kinetics. Herein, a correlation between the OER overpotential and the cobalt‐based electrode composition in a “Microparticles‐in‐Spider Web” (MSW) superstructure electrode is revealed. The overpotential...
Mesoporousintegrated TiO2 spheres composed of numerous orderly arranged nanocrystals with a reduced lattice–lattice interface connection, display an almost four times longer electron lifetime (350 ps) than the randomly aggregated nanoparticles (80 ps), and hence enhance the corresponding photocatalytic H2 and O2 generation.
