Lithium-ion battery is expected to solve environmental problems Nobel Prize in Chemistry October 10, 17:54

The lithium-ion battery developed by Akira Yoshino, the winner of the Nobel Prize in Chemistry, is expected to help solve environmental problems as a technology that opens up the possibility of realizing a society that does not use fossil fuels such as oil and coal. It has been.

Conventional solar power generation has not been able to generate power at night or on rainy days, and the problem is that the supply of power is unstable.

Therefore, if electricity is stored in the lithium-ion battery normally, it can be used stably, so this problem can be solved.

A solar power company headquartered in Tokyo has installed solar power generation facilities equipped with lithium-ion batteries at 31 mega solar power plants and public facilities nationwide.

Among them, at Konan Elementary School in Chonan-cho, Chiba Prefecture, nine years ago, a large solar power panel was installed on the rooftop and a lithium-ion battery was installed.

This elementary school was able to continue supplying emergency power to the gymnasium, which had become a refuge, due to the storage battery when the typhoon 15 last month caused a power outage.

Kazuo Higuchi, the principal of Kōnan Elementary School, said, “When I cleared the broken glass in the strong wind, I was very saved because I was able to secure power to move one vacuum cleaner. I realized the appreciation of being there. "

Ryofumi Tezuka, director of the solar power company “Smart Solar” said, “Solar power cannot be generated at night, but it can be used in combination with a storage battery to increase its function as a power source. Lithium ion for smartphones and automobiles With the widespread use of batteries, the cost has been reduced and it can now be used for storage of natural energy, so we expect that it will spread all at once.
