Enthalpic interactions of l-alanine and l-serine in aqueous urea solutions

Considering the merits of 3D mesoporous interconnected structures with large surface area of xerogel and high theoretical capacity of Co 2 (OH) 3 Cl incorporating simultaneously both chlorine and hydroxyl functional groups, it is of greatly fundamental importance and challenge to tune porous structure, surface area, and functionally doping to enhance the electrochemical performance of Co 2 (OH) 3 Cl xerogel anodes for lithium ion batteries (LIBs). Herein, we for the first time report Mn-doped Co 2 (OH) 3 Cl 3D mesoporous xerogels assembled from nanoparticles via one-step sol-gel method. The effect of Mn doping on the microstructures, surface area, charge transfer kinetics, and electrochemical performance of Mn-doped Co 2 (OH) 3 Cl xerogels are systematically investigated. It is shown that 4%Mn-doped Co 2 (OH) 3 Cl xerogels display excellent electrochemical performance, showing a superior capacity of 1377 mAh g −1 after 50 cycles at a current density of 100 mA g -1 . Even when the current density increases to 1600 mA g -1 , it still maintains the capacity of 824 mAh g -1 . The great enhancement on electrochemical performance can be mainly due to the uniquely special 3D hierarchically porous interconnected xerogel structure with high surface area, the enhancement of the electric conductivity and charge transfer kinetics, and the activated redox reaction kinetics related to LiOH and LiCl for the Mn-doped Co 2 (OH) 3 Cl xerogels.

“…The calorimetric measurements were performed with a 2277-204 Measuring Cylinder supported by a Thermometric 2277 Thermal Activity Monitor (Thermometric, Sweden) at T = 298.15 K. Details of this apparatus, associated equipment, and the experimental procedure have been reported elsewhere [19][20][21][22]. The solutions were pumped through the mixing-flow vessel of the calorimeter using VS2-10R MIDI dual channel pumps.…”
