Structure-Property of Metal Organic Frameworks Calcium Terephthalates Anodes for Lithium-ion Batteries
Metal organic frameworks have attracted considerable interest as electrode materials for lithium ion batteries. In this paper, the metal organic frameworks hydrated calcium terephthalate (CaC8H4O4 center dot 3H(2)O) and anhydrous calcium terephthalate (CaC8H4O4) as anodes for lithium ion batteries are comparatively studied. Crystallography and local chemical bond analysis are combined to interpret the structure-property of calcium terephthalates. Results show that the anhydrous CaC8H4O4 has a spacious ordered layer structure and a higher Ca-O chemical bonding interaction, delivering a higher capacity, better cycling performance and rate performance than CaC8H4O4 center dot 3H(2)O.
