Do you know the commonly used classifications and uses of batteries on the market?

The concept of a battery comes from an anatomical experiment, where the first battery was created and invented by Volt in 1800, and from then on, the performance of electricity was fully studied. Batteries can be roughly divided into two categories, one is "primary battery" and the other is "secondary battery". The most commonly used one is the battery, which is a type of "secondary battery" with advantages such as safety, reliability, stable voltage, and wide applicability. It is currently one of the most widely used types of batteries. In the late 19th century, there were already battery racks, and their principles are still in use today. The world's first battery was invented in 1905 and was mainly used for lighting in automobiles.

Simply put, a battery is a rechargeable battery that can store electrical energy as chemical energy under normal circumstances. When it needs to be discharged, the chemical energy is converted into electrical energy, mainly lead-acid batteries. The commonly used lead-acid batteries are mainly divided into three categories: ordinary batteries, dry load batteries, and maintenance free batteries. The advantages of ordinary batteries are that they are relatively cheap and have stable voltage, but the disadvantages are that they have a short service life and require frequent daily maintenance; The main characteristic of dry load batteries is their strong storage capacity; Maintenance-free batteries have distinct advantages in their own structure, making them small in size and resistant to high temperatures. In addition, lithium batteries are also relatively common. Lithium batteries and lead-acid batteries have essential differences in composition. Lithium batteries are "primary batteries" with characteristics such as small size, light weight, long service life, and good safety performance. They are widely used in electronic products, aerospace, electromechanical, solar energy storage, and so on.
