The structure and working principle of 18650 battery 3500mah lithium

　　Structure of 18650 battery 3500mah lithium

　　Lithium iron phosphate batteries have a typical orthorhombic crystal structure. Each crystal battery has four modules, an octahedron feo4 and a tetrahedron po4. The two octahedrons lio6 share edges, allowing the lithium-ion battery to move freely when charging.

　　The principle of 18650 battery 3500mah lithium

　　When the battery is charging, the lithium ion battery in the positive electrode material of the battery comes out, passes through the electrolyte of the lithium ion battery, and enters the negative electrode material of the battery through the diaphragm. When the battery is charged and discharged, the lithium ion battery passes through the electrolyte of the lithium ion battery. , returns to the cathode material through the diaphragm.

　　Advantages and disadvantages of lithium iron phosphate rechargeable batteries

　　Advantage:

　　longevity. This circulation system is used about 2000 times and can be used for 7-8 years under the same conditions.

　　High-safety lithium iron phosphate rechargeable batteries have undergone strict safety tests and are not prone to explosion even in car accidents.

　　The battery charges quickly and can be charged in 40 minutes using a professional charging head.

　　The thermal resistance value can reach up to 350~500c.

　　Large battery

　　no memory

　　Low carbon, environmentally friendly, non-toxic and zero pollution

　　defect:

　　18650 battery 3500mah lithium has small positive vibration density and large

　　Lithium-ion batteries have lower conductivity than lithium-ion batteries.

　　Low temperature characteristics

　　Lithium-ion batteries have shorter cycles in lithium iron phosphate batteries, usually up and down 500 times.
