Boosting Ultra-Fast Charge Battery Performance: Filling Porous nanoLi₄Ti₅O₁₂ Particles with 3D Network of N-doped Carbons.

ABSTRACT: Lithium titanium oxide (Li₄Ti₅O₁₂)-based cells are a promising technology for ultra-fast charge-discharge and long life-cycle batteries. However, the surface reactivity of Li₄Ti₅O₁₂ and lack of electronic conductivity still remains problematic. One of the approaches toward mitigating these problems is the use of carbon-coated particles. In this study, we report the development of an economical, eco-friendly, and scalable method of making a homogenous 3D network coating of N-doped carbons. Our method makes it possible, for the first time, to fill the pores of secondary particles with carbons; we reveal that it is possible to cover each primary nanoparticle. This unique approach permits the creation of lithium-ion batteries wi
