Mesoporous nitrogen-doped carbon materials with high surface areas up to 1500 m(2) g(-1) were conveniently made by the carbonization of nucleobases dissolved in an all-organic ionic liquid (1-ethyl-3-methylimidazolium dicyanamide). Using hard templating silica nanoparticles, this process yields high-surface-area nitrogen contents as 12 wt %, narrow mesopore size distribution ca. nm diameter, and local graphitic structure. It is demonstrated that resulting carbons show very catalytic...
A solid electrolyte framework with porous and dense layers for high-energy safe Li-metal batteries.
Sodium ion batteries (SIBs) have been considered as a top alternative to lithium due the earth abundance and low cost of sodium compared with lithium. Among all proposed anode materials for SIBs, red phosphorus (P) is very promising candidate because it has highest theoretical capacity (∼2600 mAh/g).
