One of the new lithium-ion battery technologies attracting attention is what is called a “dry process.

Let’s take a look at this technology from the perspective of materials, especially binder, which is an important element for the dry process. There are wet and dry processes for lithium-ion battery electrodes, and it is necessary to consider the advantages and disadvantages of dry processes.
The current status of new material power device development technology from silicon power devices to SiC/GaN and other new materials, semiconductor devices and mounting technology, as well as market forecast must also be done. What are power electronics (power electronics) and power devices? What is the current status and issues of SiC power devices and GaN power devices, as well as the progress of the latest silicon IGBTs? It is necessary to consider the current status of gallium oxide and diamond power devices and SiC power device high-temperature mounting technology.

As for the basis for cooling technology in EV and HEV onboard equipment, EVs are equipped with highly integrated semiconductor devices that are sensitive to heat, and it is important to maintain high reliability and safety. In addition, in-vehicle equipment, which is subject to a harsh operating environment, must not only cool the heating elements, but also keep the battery warm and heated. In order to deal with these thermal issues, it is important to know how heat behaves and to use an appropriate cooling structure. For example, before addressing the thermal issues faced by in-vehicle equipment such as EVs and HEVs, it is necessary to know the fundamentals of thermal design for in-vehicle equipment, the structure and heat dissipation route of the inverter, the heat dissipation structure of the ECU, the heat dissipation materials used in in-vehicle equipment, the battery structure and thermal measures, and the EV motor and its thermal measures. The battery structure and heat dissipation materials used in on-board devices are also important. Ultimately, it comes down to the cooling of computers for automated driving.
