What is the maximum capacity of 18650 lithium battery.

The 18650 battery generally has three types of lithium ion batteries and lithium iron phosphate ion batteries. The voltage of lithium -ion batteries is 3.6 V, 4.2 V, 3.2 V, 1200 MAH, and 2200 MAH ~ 3600mAh.

Because the volume of the 18650 lithium battery is fixed, the maximum capacity of the battery has always been the focus of the industry. With the advancement of technology, the capacity of the battery is also increasing. Samsung, Panasonic, LG, Sony, Toshiba, their battery capacity They are between 2600-3000 mAh, but the stability of the battery must be maintained between 2600-3000 mAh.

Most application occasions have different demand for current and time. Therefore, most of the power batteries use lithium ion battery packs. Therefore, when choosing a battery pack, it is important to pay attention to the consistency and stability of the battery cell. ,safety. However, the facts are exactly the opposite: 18650 lithium -ion batteries are usually divided into capacity type and multiplier type. The capacity type refers to large capacity, and discharge current is often below 1 C, and the current is relatively low. Small volume and short life. This is like what you want, but you can't get it at the same time.
At present, the 18650 lithium -ion battery purchased on the market is 2950 mAh, and some people say that it is 3000 mAh. In the capacity range of 2200 mAh to 2600 mAh, the battery performance is more stable and the technology is more mature.

In the same system, high -capacity 18650 lithium -ion batteries will generate high costs. Therefore, the balance between capacity and price is necessary. The price and capacity of the 18650 lithium-ion battery are proportional. The larger the capacity, the more materials consumed, and the higher the price. The price of a bottle is about 10-30 yuan.
