The 18650 lithium-ion battery capacity is distributed between 1000mAh and 3000mAh. Due to the particularly hot market, the price of today's 18650 lithium-ion batteries is extremely chaotic. The capacity of the 18650 lithium-ion battery pack is of concern to many industrial users and consumers, because the larger the capacity of the 18650 lithium-ion battery, the longer the usage time and the longer the power supply can be supplied to the user.

There are many types of lithium ion batteries, including power lithium ion batteries, capacity lithium ion batteries, and consumer lithium ion batteries. Power-type lithium-ion batteries and capacity-type batteries differ in materials and processing techniques. The difference in discharge characteristics means that the range of use of the two is quite different. When purchasing a Li-ion battery pack, be sure to differentiate between the two to prevent adverse effects on the load.

A sodium-based battery is one that combines sodium with a compound called inositol. Developed by researchers at Stanford University in October 2017. The sodium in the new battery binds to a compound called inositol, an organic compound commonly found in household products, including infant formula. Just as sodium is much more abundant than lithium, rice furfuryl alcohol is easily extracted from rice bran and can also be found in by-products produced during corn processing.

Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium iron phosphate is also an intercalation and deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate.

When many materials in a lithium battery come into contact with water, a violent chemical reaction occurs, releasing a large amount of thermal energy, which generates heat and burns. The manganese dioxide in the positive electrode of a lithium battery can generate heat with just a small drop of water. When the sulfurous chloride in the lithium battery comes into contact with water, it releases heat energy and produces hydrochloric acid and sulfur dioxide at the same time. If the temperature is too high, it is not normal. The reasons may be as follows:
