Definition of lithium battery what are the advantages and disadvantages of lithium battery?

First of all, let's take a look at what is a lithium battery. In fact, the lithium battery is a lithium primary battery in a strict sense. It contains pure lithium metal and is a one-time, non-rechargeable battery. Due to its own high technical requirements, only a few companies in a few countries are producing such lithium metal batteries.

Before the appearance of lithium batteries, the original battery can be said to be its originator, how was the original battery born? This dates back to the end of the 18th century, when the Italian biologist Galvani was conducting a famous frog experiment. When a metal scalpel was used to contact the frog legs, it was found that the frog legs would twitch. After many experiments, Galvani thought this might be "Animal electricity."

And Galvani’s friend, Volta, saw this phenomenon. After many experiments, it was found that as long as there are two different metals in contact with each other, the space is separated by wet cardboard, leather or other sponge-like things, with or without frog legs. There is a current generated, which negates the idea of "animal electricity." Because Volta recognizes that frog leg contraction is only a manifestation of the discharge process, the contact of two different metals is the real cause of the current phenomenon. Thus, Volta listed the order of zinc-lead-tin-iron-copper-silver-gold, which is the famous voltaic sequence. In 1800, Volta designed a device called a voltaic stack based on this principle. Zinc is the negative electrode, silver is the positive electrode, and brine is used as the electrolyte solution.

The above story is only the history of the invention of the original battery. The primary batteries that are often used by people are zinc-manganese dry batteries, zinc-mercury batteries, zinc-silver button batteries and lithium batteries. Among them, the lithium battery is derived from the great inventor Edison, which is a battery made of lithium metal or lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution. However, due to the very active chemical properties of lithium metal, lithium metal is processed and stored. In terms of use, the environmental requirements are very high, so lithium batteries have not been used for a long time in that era. Today, with the development of science and technology lithium batteries have become mainstreaming.

Since lithium batteries have become mainstream in the moment what are their advantages and disadvantages? Let us first look at its advantages: 1, high energy 2, long service life; 3, high rated voltage; 4, self-discharge rate is very low, which is one of the most outstanding advantages of the battery, less than nickel-hydrogen 1/20 of battery; 5, high temperature and low adaptability, can be used in -20 ° C - 60 ° C environment, after processing, can be used in -45 ° C environment; 6, green, regardless of production , use and scrap, do not contain, do not produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances; 7, production basically does not consume water, is suitable for countries lacking water. Disadvantages: 1, lithium battery safety is poor, there is a danger of explosion; 2, high production requirements, the cost will also rise; 3, the use of conditions is limited, high and low temperature use is dangerous.
