title: Establishment of pseudoternary LiO0.5-NiO-MnO2 phase diagram by combinatorial wet process.
abstract: A pseudoternary LiO0.5-NiO-MnO2 reaction phase diagram was established using a combinatorial high-throughput materials exploration process to find candidate electrode materials for lithium ion secondary batteries. Each powder library was prepared using our combinatorial wet process based on the electrostatic spray deposition method and results obtained at various firing temperatures in an air atmosphere and an oxide atmosphere. In the air atmosphere, newly composed single phase regions of a layered rock salt-type structure were only found around Li2MnO3 at 800 °C. On the other hand, in the oxide atmosphere, most of the powder library showed the multiphase of the spinel and layered rock salt type structure.
