Technology Summary
The theme of the development of nanotechnology in energy application technology is geared toward two main directions, “Nanomaterials for Energy Storage” and “Nanotechnology for Energy Saving”. Owing to the advantages of high reactivity, large surface area (200-2000 m2/g), self-assembly (1~3 nm active catalyst), super crystal characteristic (10~30nm nanostructure), and special optoelectronic effect of nanomaterials for energy saving, advanced countries are heavily engaged in the development of energy related nanomaterials. It is expected to develop the power storage system with higher energy density than current battery by at least several times. Due to small dimension (5-20nm) and high specific surface area and special optical property of nanomaterials, nanotechnology for energy saving is expected to increase in the contact area of the medium, shortening response time, and improving thermal conductivity by a factor of two.
