1. Lithium metal battery: Lithium metal battery generally uses manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and uses non-aqueous electrolyte solution.
2. Lithium-ion battery: Lithium-ion battery generally uses lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte.
Which type of external battery cell is best
Ternary lithium battery.
Ternary lithium batteries refer to lithium batteries that use lithium-nickel-cobalt manganate or lithium-nickel-cobalt aluminate as the cathode material. Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the cathode material. The material usedin ternary lithium batteries, nickel, cobalt and aluminum, will have unstable structure at high temperatures and may explode, so its safety at high temperatures is poor. However, ternary lithium batteries have very good low temperature performance; p>
Lithium iron phosphate batteries The high temperature performance is very good, and it can still work normally at +60℃. The disadvantage is that at low temperatures below -10°C, the battery will be greatly reduced or even unusable, which is exactly the opposite of the ternary lithium battery. Although lithium iron phosphate is small and light, it is inferior to ternary lithium batteries. Under the same size conditions, lithium iron phosphate can hold 10 Ah, and ternary lithium batteries can generally hold more than 15 Ah.
How to determine if the lithium battery cellm is lithium iron phosphate battery
Lithium ion polymer battery, 18650 lithium battery, etc.
Lithium-ion polymer batteries have different shapes, are light and small, do not explode, have high safety performance, long life, and can be charged and discharged more than 500 times.
18650 lithium battery is a best type of battery in a power bank. It has a smaller size and a higher capacity. It is suitable for low power and large capacity products. storage, and has good safety and stability performance, and can be used as a power bank
The voltage of the lithium iron phosphate battery is 3.2V and it is 3. 6V when fully charged. If there is no charge limit, you can use 4V.
Measure the voltage, usually around 3.2V for iron phosphate. Bat tensionThe lithium polymer battery is about 3.8 V and is fully charged at 4.2 V.
If the battery is seriously drained and the voltage is very low, you can charge the phone for ten seconds or more, then measure the increase in voltage. Typically, lithium iron phosphate batteries show a voltage of 3 V. Lithium polymer batteries show a voltage of 3.5 V, you can probably tell.
Once the lithium iron phosphate battery is discharged to 0V, it can still be recharged to normal.
