1) What is a 3.6V lithium battery?
A 3.6V lithium battery is a battery with nominal voltage of 3.6V and has a capacity ranging from a few hundred to a few thousand milliamperes. It is generally used in various instruments, testing instruments, medical instruments, POS machines, laptops and other products. The rechargeable battery with nominal voltage of 3.6V can reach the level of 3.7V. The early LNCM ternary material, due to technical reasons, has only a nominal voltage of 3.6V, so it has the name of 3.6V lithium battery. However, with the continuous improvement of the formula and the structure, the nominal voltage of the battery has reached 3.7V.
3.6V rechargeable batteries may refer to nickel-metal hydride batteries. The nominal voltage of nickel-metal hydride batteries is 1.2V, and the voltage after three cells connected in series is 3.6V. Therefore, we should pay attention to distinguish whether 3.6V rechargeable batteries refer to lithium batteries or nickel-metal hydride batteries.

A 3.7V battery is a lithium battery that uses lithium cobalt oxide and graphite as anode and cathode materials
The 3.6V battery is a lithium battery that uses LNCM ternary and graphite as anode and cathode materials.
Lithium cobalt oxide anode material was the standard material for the whole lithium battery industry a few years ago. Since new materials were used in batteries, a number of 3.6V or 3.8V lithium batteries have emerged in the past two years. Compared with lithium cobalt oxide batteries, different anode materials increase energy density, that is, store more energy per unit of weight and volume.
3.6V lithium batteries are widely used in Panasonic products. The anode material is LiNiCoAlO2 containing nickel. Its characteristic is that the charging limit voltage remains unchanged at 4.2V. Although the discharge platform has been slightly reduced by 0.1V, the capacity and cycling life have been increased.
The most important representative of 3.8V lithium battery is Sanyo, which replaces the positive electrode with NMC ternary material to improve the discharge platform and capacity. Meanwhile, the charging limit voltage also rises to between 4.3V and 4.35V. Common products that use 3.8V batteries include ipad2, iphone 3, iphone5 and HTC one.
Thanks to BYD promotion of its electric cars, the term "lithium iron phosphate" has gained popularity in China in recent years. Take lithium iron phosphate for example, its anode material voltage standard value is usually between 3V~ 3.3V. At the expense of energy density, it improves the safety and cycling life, which is more suitable for safety performance in electric vehicles.
The battery voltage above is monomer battery. In order to improve the voltage or increase capacity, it usually connects multiple batteries in series and parallel. For example, digital camera common 7.4 V composes of two 3.7 V cells in series, while 11.1 V 5200 mAh battery consists of 6 3.7 V 2600 mAh 2 cells in series and 3 cells in parallel.
A 3.6V lithium battery charger is a device that charges a 3.6V rechargeable battery and provides power to a storage device. 3.6V lithium battery charger and other rechargeable battery chargers are basically the same. They are made up of shell, input/output wire, circuit board, radiator, various electronic components and so on. In principle, it is composed of a stable power supply and necessary constant current, voltage limit, time limit control circuits. The charger process is as follow: constant current - constant voltage - trickle, three - stage intelligent charging.
3.6V lithium battery charger features:
1. The charging current of each charging port can be set manually.
2. High-precision please refers to voltage source calibration.
3. The battery will automatically stop charging when it is fully charged.
4. It has short circuit protection function.
5. Detect the battery automatically and display the charging status.
6. It can measure the battery resistance automatically.
7. Support independent charging of different circuits.
8. It has good heat dissipation function.
