As a  Samsung 4000amh Battery Factory , share with you. Cylindrical 18650 lithium battery 18650 battery is a cylindrical lithium battery with a diameter of 18mm and a height of 65mm. Its biggest feature is that it has a very high energy density, almost 170 Wh / kg. Therefore, this battery is a cost-effective battery. This battery is often seen because it is a relatively mature lithium battery with good system quality stability in all aspects. It is widely used in battery capacity applications of about 10 kWh, such as in small appliances such as mobile phones and notebook computers. on. 21700 Battery 21700 battery is a lithium battery with a diameter of 21mm and a height of 70mm. Because of its increased volume, space utilization becomes larger, and the energy density of the battery cell and the system can be improved. Its volume energy density is much higher than 18650. Type batteries, widely used in digital, electric vehicles, balanced vehicles, solar energy lithium batte...

As a  Wholesale 18650 Battery , share with you. Advantage: 1. Large capacity  18650 Battery  capacity is generally between 1200mah ~ 3600mah, and the general battery capacity is only about 800mah, if combined into an 18650 lithium battery pack, then 18650 lithium battery pack can easily break through 5000mah. 2. Long life 18650 lithium battery life is very long, the cycle life under normal use can reach more than 500 times, more than twice the ordinary battery. 3. High safety performance 18650 lithium battery has high safety performance, no explosion, no combustion; non-toxic, no pollution; various safety performances in one go, cycle times more than 500 times; good high temperature resistance, discharge efficiency up to 100% at 65 degrees . To prevent battery short circuit, the positive and negative electrodes of 18650 lithium batteries are separated. So the possibility of its short circuit has been reduced to the extreme. A protection board can be installed to ...

As an  18650 Battery Factory , share with you. Lithium ion battery: Lithium ion battery has the advantages of light weight, large capacity and no memory effect, so it is widely used-many digital devices use lithium ion battery as power source, although its price is relatively expensive. The energy density of a lithium-ion battery is very high, its capacity is 1.5 to 2 times that of a nickel-metal hydride battery of the same weight, and it has a very low self-discharge rate. In addition,  SANYO Lithium Ion Battery  has almost no "memory effect" and does not contain toxic substances and other advantages are also important reasons for its widespread use. 4.2 v 18650 Battery 4.2 v 18650 Battery  life theory for 1000 cycles of charging. Due to the large capacity per unit density, most of them are used in notebook computer batteries. In addition, 18650 is very stable in work and is widely used in major electronic fields: often used in high-end strong flashlights, ...
