If the manufacturer says that the 18650 battery can produce 9800 mAh battery, then it is a lie. Remember not to believe it. Today, the highest capacity of 18650 lithium batteries on the market is only 3600 mAh, which is still achieved by very few manufacturers.
Lithium batteries are commonly used in electronic products and are often used as batteries in laptop computers. The rule for defining its model is: Type Ru, which designates a cylindrical battery with a diameter of 18 mm and a length of 65 mm. Among the world's largest manufacturers of lithium batteries of this type are the Japanese Sanyo (acquired by Panasonic), Panasonic, Samsung, Sony, etc. Lithium ion battery is a lithium battery commonly used in electronic products and is often used as a battery core in laptop batteries. The rule for defining its model ist: Type Ru, which designates a cylindrical battery with a diameter of 18 mm and a length of 65 mm.
Lithium is a metallic element, and its positive electrode is a battery using "lithium cobalt oxide" as the positive electrode material. Of course, there are many batteries on the market now, including lithium iron phosphate and lithium. manganate, etc. as a positive electrode Materials for batteries.
Maximum charging termination voltage: 4.20 V (the latest large capacity 18650 from Sanyo, Samsung and Panasonic has a charging termination voltage of 4.35 V) Diameter: 18 ± 0.2 mm, Height: 65 ± 2.0 mm, Capacity: 1000 mAh Above (the highest known is Panasonic's 3100 mAh), the world's largest manufacturers of this type of lithium battery include Japan's Sanyo (acquired by Panasonic), Panasonic, Samsung, Sony, etc. Sony was responsible for the famous laptop battery. exposion. The incident was a big headache.
