Advantages of the 26650 Lithium-Ion Battery

26650 lithium-ion batteries are now mainly used to replace traditional nickel-chromium and nickel-metal hydride batteries, and are used in mining lamps, flashlights, power tools, toys, instruments, rear switching power supplies, communication equipment, medical equipment and their military lighting industries. Compared with nickel-chromium and nickel-metal hydride batteries, its advantages are reflected in the following aspects: 1. […]

What is the Maximum Capacity of the 26650 Lithium Battery

The 26650 lithium battery is a high-capacity, high-density rechargeable battery. It weighs 98 grams and is 26.5 millimeters across. The size of the 26650 lithium battery is 68.2 millimetres in height and 26.5 millimetres wide. This means that it has a higher capacity than the 18650 battery. The maximum capacity of the 26650 lithium battery […]

What is the Maximum Capacity of an 18650 Lithium Battery

Due to the fixed size of the 18650 battery, its maximum capacity has always attracted the attention of many practitioners. In recent years, the technology of various manufacturers has improved, and the capacity has also increased accordingly. Samsung, Panasonic, LG, Sony, and Toshiba can achieve more than 3600mAh. However, the best stability and consistency is […]

How to Judge Positive and Negative Electrodes of an 18650 Lithium Battery

To determine which electrodes are the positive or negative in an 18650 lithium battery, you need to know how to identify them. The positive electrode is made of aluminum cobalt oxide while the negative one is made of carbon, usually in a layered structure called graphite. In any case, the electrodes are flat and connected […]

Why 18650 Lithium Batteries Are Burning Or Exploding

1. Internal short circuit: Structural or process defects lead to the insertion of the tabs, too little excess diaphragm wrapping, burrs, and diaphragm discounts, etc. The insertion of the tabs often occurs in the structure of thick batteries and internal parallel connection, and the insulation of the tabs is not in place. Adding a protective […]
