Abstract
Inorganic/organic hybrid materials composed by iron atoms bonded to an alkyl phosphate can be easilysynthesized by mixing at 110°C iron chlorides with tri-alkyl phosphates.Since structural information on these products are lacking and taking into account that lithium/ironorganic hybrid materials are important in lithium ion battery technology we report here the physico-chemical characterization of different hybrid lithium/iron butylphosphates. These materials are charac-terized by the presence of elongated hexagonal crystals stable up to 315°C. The insertion of lithium doesnot affect the local structure. Thanks to such structures the material can be electrochemically-cycled andLi ions can find facilitated pathways for travel and redox reactions| File | Dimensione | Formato | |
