What is Lithium ion battery
Lithium ion battery is a secondary battery (rechargeable battery), which mainly depends on the movement of lithium ions between the positive and negative electrodes. During charging and discharging, Li + is intercalated and de intercalated back and forth between the two electrodes: during charging, Li + is de intercalated from the positive electrode and embedded into the negative electrode through electrolyte, and the negative electrode is in a lithium rich state; The opposite is true when discharging.
On October 9, 2019, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in chemistry would be awarded to John goodinaf, Stanley Whittingham and Akira Yoshino in recognition of their contributions in the field of lithium-ion battery research and development.

Why Purchase FBELE Lithium ion battery
Novel lithium ion battery,No pollution, no memory effect.
FBELE Lithium ion battery is exquisitely made of high-quality materials, with stable performance, safety and reliability
Generally, it can reach more than 500 times, or even more than 1000 times, and the lithium iron phosphate can reach 8000 times.
The working voltage of single battery is as high as 3.7-3.8v (3.2V for lithium iron phosphate), which is three times that of Ni Cd and Ni MH batteries.
Advantages of Lithium ion battery
1) High voltage
The working voltage of single battery is as high as 3.7-3.8v (3.2V for lithium iron phosphate), which is three times that of Ni Cd and Ni MH batteries.
2) Greater specific energy
The actual specific energy that can be achieved is about 555wh / kg, that is, the specific capacity of the material can reach more than 150mah / g (3-4 times that of Ni Cd and 2-3 times that of Ni MH), which is close to about 88% of its theoretical value.
3) Long cycle life
Generally, it can reach more than 500 times, or even more than 1000 times, and the lithium iron phosphate can reach 8000 times. For electrical appliances with low current discharge, the service life of the battery will multiply the competitiveness of electrical appliances.
4) Good safety performance
Novel lithium ion battery
No pollution, no memory effect. As the predecessor of Li ion, lithium battery is easy to form dendrite and short circuit, which reduces its application field: Li ion does not contain cadmium, lead, mercury and other elements that pollute the environment; A major disadvantage of Ni Cd batteries with some processes (such as sintering type) is “memory effect”, which seriously restricts the use of batteries, but Li ion does not have this problem at all.
5) Small self discharge
The self discharge rate of fully charged Li ion stored at room temperature for one month is about 2%, which is much lower than 25-30% of Ni Cd and 30-35% of Ni MH.
6) Fast charging
The capacity of 1C can reach more than 80% of the nominal capacity after charging for 30 minutes, and that of ferrophosphate battery can reach 90% of the nominal capacity after charging for 10 minutes.
7) Operating temperature
The working temperature is – 25 ~ 45 ° C. with the improvement of electrolyte and cathode, it is expected to be widened to – 40 ~ 70 ° C.
Attention for Lithium Battery Manufacturing Process of lithium ion battery
The cathode materials of lithium battery include lithium cobalt oxide LiCoO2, ternary material Ni + Mn + CO, lithium manganese oxide LiMn2O4 plus conductive agent and adhesive, which are coated on aluminum foil to form the cathode. The cathode is layered graphite plus conductive agent and adhesive, which is coated on copper foil baseband. The more advanced layered graphite particles of cathode have adopted nano carbon.
- Pulping: special solvents and binders are used to mix with powdered positive and negative active substances respectively. After stirring evenly, the slurry positive and negative substances are made.
- Coating: the positive and negative electrode pastes are evenly coated on the surface of metal foil by automatic coater, and automatically cut into positive and negative electrode sheets after automatic drying.
- Assembly: according to the sequence of positive pole piece diaphragm negative pole piece diaphragm from top to bottom, the process of winding and injecting electrolyte, sealing, welding of positive and negative lugs, that is to complete the assembly process of the battery and make the finished battery.
- Formation: put the finished battery in the test cabinet for charge and discharge test, and select the qualified finished battery to be delivered
