In this study, we report the hydrogen storage in aluminum hydride coated single-walled carbon nanotube. All the H 2 adsorption is molecular with H – H bond length of 0.756 Å. The hydrogen storage capacities with half and full coverages are 6.01 (8.3) wt% and 7.2 (10.3) wt%, respectively, without (with) H 3 of AlH 3. At high coverage of AlH 3 ( C 10 AlH 3) interesting clustering/ dimerization of AlH 3 is observed. These systems are quite stable and the H 2 can be extracted from the system without disturbing the C – Al bonding or detaching the AlH 3 from the carbon nanotube. This present study on a full molecular adsorption of hydrogen via light metal-hydride AlH 3 is new and it leads to a practically viable hydrogen storage process.

ABSTRACTOlivine lithium manganese phosphate, LiMnPO4 is a promising cathode material for high energy and safe lithium ion batteries. However, LiMnPO4 possesses excessively poor electrochemical activity, compared to conventional cathode materials. To enhance the electrochemical activity, we have synthesized LiMnPO4/multi-walled carbon nanotube (MWCNT) composites by employing an in-situ sol-gel method. The LiMnPO4/MWCNT composites were investigated by utilizing X-ray diffraction, thermogravimetric analysis, scanning electron microscope, transmission electron microscope, and galvanostatic charge-discharge cycling. The LiMnPO4 showed a particle size of ca. 50 nm and capacity of 102 mAh/g at 0.1 C without C.V. charging mode. This study demonstrated that the electrochemical activity of LiMnPO4 was significantly affected by not only pH and the amount of a chelating agent but also unreacted Mn2+. This is the first report analyzing the existence and effects of unreacted Mn2+ in LiMnPO4 synthesized by a sol-gel method.
