Lithium metal is one of the most promising candidates as an anode material for next-generation energy storage systems due to its highest specific capacity (3860 mAh/g) and lowest redox potential of all. The uncontrolled lithium dendrite growth that causes a poor cycling performance and serious safety hazards, however, presents a significant challenge for(More)
Lithium-sulfur batteries have attracted attention due to their six-fold specific energy compared with conventional lithium-ion batteries. Dissolution of lithium polysulfides, volume expansion of sulfur and uncontrollable deposition of lithium sulfide are three of the main challenges for this technology. State-of-the-art sulfur cathodes based on metal-oxide(More)
Porous graphitic carbon is essential for many applications such as energy storage devices, catalysts, and sorbents. However, current graphitic carbons are limited by low conductivity, low surface area, and ineffective pore structure. Here we report a scalable synthesis of porous graphitic carbons using a conjugated polymeric molecular framework as(More)
The whole chloroplast (cp) genome sequence of Cupressus chengiana has been characterized from Illumina pair-end sequencing. The circular genome is 128,151 bp in length with 115 single copy genes and two duplicated genes (trnl-CAU, trnQ-UUG). This genome contains 82 protein-coding genes, 31 tRNA genes and four ribosomal RNA genes (four rRNA species). In(More)
