R&D of Eco-Friendly/low-cost thermoelectric modules
～Low-cost thermoelectric generation and electronic cooling without using rare metals! ~
Under development for 2022
What is a thermoelectric module
Electronic components that utilize thermoelectric materials, which convert electricity into heat and heat into electricity
Features of Developed Products
Thermoelectric module using rare metals
- Environmental Considerations
→Bismuth and tellurium, the constituent materials, are both rare metals.
→Tellurium reserves of less than 40,000 tons.
- High cost
→Most of the modules are tellurian prices.
→Price fluctuates widely due to a bias towards resource reserve areas.
→ Only uses that are cost effective (Temperature control of semiconductor lasers for communication)
Thermoelectric module using raw materials (magnesium, silicon and tin) that do not contain rare metals
- Abundant raw materials
→The constituent materials, magnesium, silicon, and all tin is a common element.
→1,800 trillion tons of magnesium reserves.
- Low cost
→Rare metal free, so significant cost reductions
→Composed of raw materials that can be mined around the world
→In fields that have not been used in the past. Applicable as a cooling method
Realizing high-performance thermoelectric conversion materials using ceramic manufacturing technology for lightning protection products
