Characteristics and prospects of lithium batteries

　　For modern people, mobile phones have long become a "companion level" necessity in daily life. Running out of battery while playing is a "bolt from the blue", but the battery of mobile phones is also a lithium battery. Do you feel that batteries nowadays are becoming less durable? Let's learn about it together

　　Nowadays, most mobile phones or various 3C digital devices are lithium batteries, which operate in the same way as batteries that appeared 200 years ago: one end of the battery is lithium, the other end is usually carbon, and the middle is an electrolyte solution through which lithium ions travel back and forth.

　　One advantage of lithium batteries is that they can be used at any time, interrupted at any time, and can be charged or unplugged if needed, which is very convenient.

　　The lifespan of lithium batteries is affected by the "charge discharge cycle". Generally speaking, the charging and discharging cycle of a lithium battery is around 500 times, and the consumption of charging and discharging cycles means that the lifespan of the lithium battery has come to an end. That's also why our phones usually go unused after about three years of use.

　　Today, lithium batteries are used in mobile phones, cars, digital cameras, electronic cigarettes, power tools, ships and spacecraft, as well as the Curiosity Mars rover. But the problem with lithium is that it is flammable.
