"Reinforced concrete-like Na3.5V1.5Mn0.5(PO4)3@graphene hybrids with hi" by Tao Long, Peng Chen et al.
Realizing high-rate capability and high-efficiency utilization of polyanionic cathode materials is of great importance for practical sodium-ion batteries (SIBs) since they usually suffer from extremely low electronic conductivity and limited ionic diffusion kinetics. Herein, taking Na3.5V1.5Mn0.5(PO4)3 (NVMP) as an example, a reinforced concrete-like hierarchical and porous hybrid (NVMP@C@3DPG) built from 3D graphene (“rebar”) frameworks and in situ generated carbon coated NVMP (“concrete”) has been developed by a facile polymer assisted self-assembly and subsequent solid-state method....
