The world's first aluminum-ion solid-state battery is mass-produced, which is half cheaper than lithium batteries
Saturnose, an Asian battery research and development company, announced that it will publicly release independent test results of enhanced aluminum-ion batteries, and plans to launch solid-state rechargeable aluminum-ion batteries, which will be released as soon as next year. This may be the world's first mass-produced commercial-grade aluminum-ion solid-state battery, which is expected to replace the risky lithium-ion battery.
18650 lithium battery has high energy density, so most of it is used in laptop battery. In addition, because 18650 has very good stability in work, it is widely used in various electronic fields. Commonly used in high-end glare flashlights, portable power supplies, wireless data transmitters, electric heating suits, shoe materials, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.
Cylindrical lithium-ion batteries are usually represented by five digits. Counting from the left, the first and second digits are the diameter of the battery, the third and fourth digits are the height of the battery, and the fifth digit represents the cylindrical shape. There are many types of cylindrical lithium batteries, the more common ones are 10400, 14500, 16340, 18650, 21700, 26650, 32650 and so on.
