Metallic lithium anode is widely applied to building highenergy-density batteries such as lithium-sulfur and lithiumoxygen batteries because of its high specific capacity (3860 mAh g-1) and lowest negative potential (-3.04 V vs.standard hydrogen electrode (SHE)) [1,2].

The Upper Devonian Buchan Formation reservoirs in the UK Central North Sea are litharenite/sublitharenite and were deposited in fluvial-aeolian settings.The grain-coating clays in the aeolian sandstones have effectively inhibited quartz overgrowth.Hence,t
A new classification of petroleum systems (PSs) based on reservoir qualities is proposed.We classify PSs into the following three basic types:(1) source-rock petroleum system (SPS);(2) tight-reservoir or tight petroleum system (TPS);and (3) conventional-r
It is important to predict the fracture distributionin the tight reservoirs of the Ordos Basin because fracturing is very crucial for the reconstruction of the low-permeability reservoirs.Three-dimensional finite element models are used to predict the fra
The Triassic fluvial sandstones of the Skagerrak Formation were deposited in a series of salt-walled mini-basins and act as important hydrocarbon reservoirs for several high-pressure,high-temperature (HPHT) fields in the Central Graben,North Sea.The HPHT

The molecular composition and biomarker distribution of various occurrences of organic matter in argillaceous source rocks developed in fresh and saline lacustrine environments were revealed by successive treatments of solvent extraction followed by acid
Carbonates have been known to act as hydrocarbon source rocks,but their basic geochemical and associated hydrocarbon generation characteristics remain not well understood as they occur with argillaceous source rocks in most cases,and the hydrocarbon gener
Zinc-air batteries provide a great potential for future large-scale energy storage.We assess the test factors that mainly affect the measured power density of the zinc-air battery.By fitting the polarization curves of the zinc-air batteries,we reveal the
Transition metal sulfides are emerging as promising electrode materials for energy storage and conversion.In this work,hierarchical FeS2/C nanospheres are synthesized through a controllable solvothermal method followed by the annealing process.Spherical F
