The binary In - Li system is a promising Li-ion battery anode material as well as a part of the important ternary Ge - In - Li system. The thermodynamic descriptions of metallic systems are widely used to retrieve information necessary for alloy applications. In this work, a thermodynamic model of a binary indium - lithium system prepared by the Calphad approach is proposed. The liquid phase was described by an associate model, and the solid phases determined by the ab-initio calculation were included in thermodynamic modeling. The obtained set of self-consistent thermodynamic parameters well reproduces the available experimental data and enables further calculations of multi-component systems. A good agreement between the calculations and the available experimental data was found. The proposed model can be used for further descriptions of ternary systems.

As the demand of the rechargeable battery has been requested not only from operating the small devices, but also from operating the large and medium size equipment such as an electric vehicle, the research has been focused on the stability of the battery, minimization of the energy loss, and finding the new materials for effective energy storage. The Lithium-ion (Li-ion) battery consists of four main components which are cathode active material, anode active material, electrolyte, and the separator. One of current research fields of the Li-ion battery material is in the area of cathode active material. It is because the cathode active material has 30∼40% of the manufacturing cost and it vastly affects the capacity of the batteries. In this research, we conduct one-cell simulation to compare the battery performance for changing the properties of the Cathode material. It is one of the thermochemical parameters that can affect the charge/discharge rate and the life of the batteries. Although, the certain kind of active materials has been reported in previous reports, we used the new material properties and researched about the whole discharge curve for future material development. The heating behavior is also investigated with the arbitrary properties being varied.

We show the occurrence of local cation ordering in Li-ion battery material Li<sub>1.25</sub>Nb<sub>0.25</sub>Mn<sub>0.5</sub>O<sub>2</sub>, previously thought to be disordered. We deduce this ordering from X-ray diffraction, and test it against neutron diffraction & PDF, magnetic susceptibility and solid state NMR evidence. We identify the nature of the ordering as having a local structure related to that of gamma-LiFeO<sub>2</sub>, determine the correlation length of such ordering, and demonstrate its significant consequences for the material's electrochemistry.

Battery Material

Lithium-ion batteries are crucial for non-emission technologies, like electric vehicles and renewable energy sources. The growing battery market causes supply risks for affected raw materials like cobalt, nickel, natural graphite and, in the future, lithium. On the other hand, the number of end-of-life Li-ion batteries grows significantly and provides an additional source for these critical materials via recycling. In electrohydraulic fragmentation (EHF), Li-ion battery cells are disintegrated at component interfaces, thus separating those components. Battery materials like cathode active material, graphite, electrode foils and housing parts can be extracted for producing new batteries or for further refining in hydrometallurgical processing. Compared to state-of-the-art pyrometallurgical recycling, the EHF is more energy and cost efficient due to the easy processing to a valuable battery material product.
