"Cathode nanoarchitectonics with Na3VFe0.5Ti0.5(PO4)3: Overcoming the e" by Vaiyapuri Soundharrajan, Sungjin Kim et al.
High electrochemical stability and safety make Na+ superionic conductor (NASICON)-class cathodes highly desirable for Na-ion batteries (SIBs). However, their practical capacity is limited, leading to low specific energy. Furthermore, the low electrical conductivity combined with a decline in capacity upon prolonged cycling (>1000 cycles) related to the loss of active material-carbon conducting contact regions contributes to moderate rate performance and cycling stability. The need for high specific energy cathodes that meet practical electrochemical requirements has prompted a search for ne...
