Distribution expressions of total gas pressure and partial water vapor pressure along the channel direction were established based on lumped model by analyzing pressure loss in the channel and gas diffusion in the layer. The mechanism of droplet formation in the flow channel was also analyzed. Effects of the relative humidity, working temperature and stoichiometry on liquid water formation were discussed in detail. Moreover, the force equilibrium equation of the droplet in the flow channel was deduced, and the critical flow velocity for the water droplet removal was also addressed. The experimental results show that the threshold position of the liquid droplet is far from the inlet with the increase of temperature, and it decreases with the increase of the inlet total pressure. The critical flow velocity decreases with the increase of the radius and the working pressure.

Loosely packed MoS2 nanosheets with thin carbon coating were synthesized via a facile, one-pot hydrothermal growth method. In the resulted optimal-designed nanoarchitecture, the ultrathin nanosheets, with a wall-thickness of approximately 5-10 nm, provide large electrode-electrolyte interface, so as to facilitate faster lithium-ions intercalation and diffusion. The flexible and conductive carbon overcoats accommodate and alleviate the volume variation of the composites and thus maintain the structural and electrical integrity. In favor of the synergy and interplay of the carbon effect and intrinsic structural advantages, MoS2@C (1:2) composites with the precursor MoO3: D-glucose molar ratio of 1:2 exhibit high reversible specific capacity of 1419 mA h g-1 at 0.1 A g-1, retain 80 % of the capacity after 50 cycles, and excellent rate capability as high as 672 mA h g-1 at 10 A g-1 with almost 100 % Coulombic efficiency. The good electrochemical performance suggests that these MoS2@C composites with unique flower-like morphology give rise to high specific surface area and increased layer distance leading to the reduced diffusion path of lithium-ions and rapid electrons transport. The rational and optimal design of the MoS2@C composites with an excellent electrochemical performance in the report creates a new avenue to develop a high-performance anode material.
