Spark plasma sintered carbon electrodes for electrical double layer capacitor applications [PDF]

, 2011
The spark plasma sintering (SPS) is an emerging process for shaping any type of materials (metals, ceramic, polymers and their composites). The advantage of such a process is to prepare densified ceramic materials in a very short time, while keeping the ...

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Constructing Ionic Fast Diffusion Channels on LiNi0.5Mn1.5O4 for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A dual‐modification strategy is developed for LNMO cathode, where bulk Ti doping stabilizes the oxygen framework and simultaneously drives the in situ formation of LaTi2O6 nano‐islands as ion diffusion channels on (111) surfaces, enabling high‐rate capacity (∼100 mAh g−1 at 30 C) and excellent cycling retention (87.8% after 1000 cycles).
