T

oray Industries, Inc. has developed a non-porous separator for lithium ion batteries that could dramatically increase capacity by enhancing safety of lithium metal anode batteries, notably in wearable electronic devices, drones, and electric vehicles.

The lithium ion battery market continues to expand, underscoring the need to lift the capacity and energy density of lithium ion batteries. This situation has focused attention on lithium metal anode because of their high theoretical capacity and low redox potential. Redox potential is a measure of the oxidization or reduction of electrons in substances. In a battery, a low reduction potential of the anode and a high oxidation potential of the cathode makes it possible to increase voltage and attain high capacity. This anode has not seen practical use, however, as lithium dendrites form on lithium metal surfaces during charging, penetrating separators and causing short circuits that deteriorate safety.

New Growth Technology Targets High-Quality Gallium Nitride Crystals
I

n collaboration with Tokyo Institute of Technology, National Institute for Materials Science (NIMS) has developed a new technology that can significantly reduce defects and obtain high-quality crystals in the growth of gallium nitride (GaN), which is expected as the semiconductor material for next-generation power devices. By applying an alloy liquid to a substrate to grow crystals instead of conventional growth in a solution, prevents the undesirable inclusion of solutions trapped and accumulated in the crystals. It is expected to be put into practical use as the fabrication technique of next-generation power devices for electric vehicle (EV) motor control units.

Because gallium nitride semiconductors can withstand larger currents and voltages than silicon, vigorous development is being conducted for applications such as next-generation power devices for automobiles. In the conventional gallium nitride single crystal growth method in which the raw material gas is deposited onto a substrate, a large amount of atomic misalignment is introduced in the crystal. When a large current is applied, damage in the device starts to grow from these defects, posing a fundamental problem. Currently, therefore, synthetic methods called the amonothermal method and the sodium flux method are actively developed. In these methods, crystals are grown in a solution containing raw materials and crystal misalignment at the atomic level such as dislocation defects can be minimized. However, new problems peculiar to the solution growth have to be overcome, such as the inclusion in which undesirable solution components are aggregated and left behind in crystals.
