Abstract EN
In this work, we examined the use of nanospinels to construct batttery electrodes.
We chose two spinels suitable as cathode materials (LiMn2O4 and LiNi0.5Mn1.5O4, which are representative of 4 and 5 V versus Li metal, resp.) and one providing good results as anode (Li4Ti5O12).
In order to ensure good cell performance, nanometric particles must meet another requirement; thus they should contain few surface or bulk defects (i.e., they should be highly crystalline).
Because the synthesis of such spinels usually requires a thermal treatment, ensuring that they will meet both requirements entails accuratly controlling in the synthesis conditions.
Thermal decomposition of nanooxalate in the spinel-conaining elements obtained by mechanochenical activation in the presence of polymers provides a simple, effective route for this purpose.
We prepared two types of hybrid lithium-ion batteries using LiMn2O4 and LiNi0.5Mn1.5O4 as cathode materials, and Li4Ti5O12 as anode material.
The electrochemical properties of these cells were compared with those of a similar configuration made from micrometric particles.
The nano-nano configuration exhibited higher reversibility and better performance than the micro-micro configuartion in both types of cells, possibly as a result of lithium ions in the former being able to migrate more easily into the electrode material.
