18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery. Lithium battery 18650 is the originator of lithium ion battery. 18650 is a standard lithium-ion battery model for lithium-ion batteries. 18650 batteries are the earliest, most mature and most stable lithium-ion batteries, and are widely used in electronic products. The consistency of the battery cannot meet the requirements, and the management of a battery pack formed by a large number of batteries connected in series and parallel will not allow the performance of each battery to be better played, and the 18650 battery can solve this problem.
What is a lithium battery
The earliest lithium battery came from the great inventor Edison. Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive/negative electrode materials and use non-aqueous electrolyte solutions. Lithium batteries generally have a nominal voltage higher than 3.0 volts and are more suitable for integrated circuit power supplies. The advantages of the lithium battery's extremely low self-discharge rate and gentle discharge voltage enable the pacemaker implanted in the human body to operate for a long time without recharging.
Lithium batteries come from the stability and reliable safety design of positive electrode materials. Lithium iron phosphate batteries have passed strict safety tests and will not explode even in severe collisions. Lithium iron phosphate has high thermal stability and electrolyte oxidation ability low, so the security is high.
What is the difference between lithium battery and storage battery
The storage battery has a memory effect, so it cannot be charged and discharged at any time; there is a serious self-discharge phenomenon, and the battery is easily scrapped after being left for a period of time; the discharge rate is small, and it cannot be discharged at a high current for a long time. Lithium battery has no memory effect; the battery can be charged and discharged at any time, and the battery self-discharge is low.
The difference in greenness. Lithium battery materials do not contain any toxic and harmful substances, and are regarded as green and environmentally friendly batteries by the world, and storage batteries are hazardous waste. The storage battery is a kind of battery. Its function is to store limited electric energy and use it in a suitable place. It works by converting chemical energy into electrical energy. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
