Why are lithium-ion batteries dangerous?
The interior of the lithium-ion battery is structured in which the + poles and – poles are isolated by separators (insulating films). If the separator is damaged by deformation or damage due to disassembly of the smartphone, it may cause internal short-circuit, causing the battery to smoke, fire, or burst.
How many years does a lithium-ion battery last?
The estimated lifespan of lithium-ion batteries is approximately 6,000-12,000 cycles and 10-15 years of use.

What are the drawbacks of lithium polymer batteries?
Lithium polymers are batteries that have been gelled by adding polymer to an electrolyte. While they have the freedom of shape and light weight, they are dangerous if they bent or subjected to impact, so be careful. They may swell due to overcharge or overdischarge, and if they short, they may cause fire or flames. They are mainly used in mobile phones, smartphones, tablets, etc.
Why should you not put lithium-ion batteries in your plane?
Lithium-ion batteries built into mobile batteries have the risk of heat generation or ignition if they are exposed to strong external impacts. Therefore, air cargo is treated as a “dangerous item” and is prohibited from being placed in checked baggage.
Which company mines rare earths in Japan?
This is the first time that investment support will be provided in a business that will contribute to the acquisition of rights of heavy rare earths, and this will be the first supply contract to Japan for a project to be integrated into heavy rare earths from a mine in which Japanese companies participate.

What is the difference between Bosch and Miele?
Miele automatically opens the door to further improve the drying finish. AutoOpen drying is a unique patented feature. Meanwhile, Bosch uses the residual heat of zeolite, so the door does not open. This is also a function necessary to further improve the drying finish.ナトリウムイオン電池
Why is Volta batteries bad?
Volta batteries, which were inspired by Galvani’s experiments, had a weak power generation and only a very small amount of current could be passed through. The cause was that hydrogen (H2) generated at the positive electrode accumulates around the copper plate, and H+ (hydrogen ions) in the aqueous solution interfered with e- (electrons) from the negative electrode.
