Next Generation Na-Ion Batteries & High Safety Li-Ion Batteries

Recently, the demand for large-scale lithium-ion batteries is rapidly grown as power sources for the electric vehicles. Lithium is the key element for the lithium-ion batteries. Nevertheless, the lithium source in the earth’s crust is limited in South America, leading to the possible restriction on the large-scale applications. Sodium-ion battery is the promising alternative technology of the lithium-ion batteries because sodium resource is unlimited everywhere.

Now, we are developing the positive and negative electrode materials for the sodium-ion batteries. As one of newly developed positive electrode materials in our group, NaNi0.5Mn0.5O2 delivers ca. 120 mAh g-1 of the rechargeable capacity with good capacity retention, which is comparable capacity with LiCoO2 known as a conventional lithium-ion electrode material. We also demonstrate that a hard carbon electrode is used as the negative electrode materials for the sodium-ion batteries. The hard carbon electrode delivers more than 200 mAh g-1 of te rechargeable capacity over 100 cycles by selecting electrolyte solutions. From these results, we will discuss the possibility and actuality of the sodium-ion batteries in the future.Our research effort also covers the improvement of the safety issues of the lithium-ion batteries, which is the primary problem to develop the large-scale lithium-ion batteries for the transportation system. We explain the high-energy and highly safe lithium-ion batteries using nonflammable ionic liquid electrolyte.
