Is there a difference between the 14500 battery and the 5th battery?

The 14500 lithium battery is a lithium battery with a diameter of 14 mm and a height of 50 mm. It is divided into lithium iron phosphate battery and lithium cobalt oxide battery according to the core material. The lithium cobalt oxide battery voltage is 3.7 v, and the lithium iron phosphate battery voltage is 3.2 v. Because its size is the same as that of AA5 # battery, one 14500 lithium battery and one occupancy barrel can be used instead of two AA batteries.

Can I charge? I can charge. Compared with nickel-metal hydride rechargeable batteries, lithium batteries have the advantages of light weight, less self-discharge and superior discharge performance. Therefore, they are widely used by digital photographers and electronic cigarettes instead of nickel-metal hydride rechargeable batteries.

What is the endurance? It should be OK, depending on what appliance you use and the frequency, intensity and duration you use, its nominal capacity is 1600 mah.

It is a lithium battery with a diameter of 14 mm and a height of 50 mm. It is divided into a lithium iron phosphate battery and a lithium cobalt oxide battery according to the core material. The lithium cobalt oxide battery voltage is 3.7 v, and the lithium iron phosphate battery voltage is 3.2 v. The voltage can be adjusted to 3.0 v by a lithium battery regulator. Because its size is the same as that of AA5 # battery, one 14500 lithium battery and one occupancy barrel can be used instead of two AA batteries.

Comparison of advantages and disadvantages

Lithium cobaltate is currently the most widely used lithium ion battery cathode material, with mature technology, stable structure, high specific capacity and outstanding comprehensive performance. The disadvantages are poor safety and high cost, mainly used for small and medium-sized batteries.

lithium iron phosphate is a new cathode material for lithium-ion batteries. It has good safety, no explosion, good cycle performance (up to 2000 times), but its energy density is much lower than that of lithium cobalt oxide and ternary materials. More suitable for electric vehicles, power tools and other fields.

1, AA14500 nickel-metal hydride, rechargeable battery. 14500 lithium rechargeable battery. No. 5 battery is a non-rechargeable disposable dry battery.

2, AA14500 nickel-metal hydride voltage is 1.2 volts, after filling up to 1.4 volts. 14500 lithium battery voltage is 3.7 volts, 4.2 volts after full charge. The No. 5 battery is nominally 1.5 volts and the voltage is reduced to about 1.1 volts.

3, each has its own application occasions, which cannot replace each other.

145005 battery and battery size are the same

14500 means the battery is 50 mm high and 14 mm in diameter.

The No. 5 battery is generally referred to as a disposable battery or a nickel-hydrogen nickel-cadmium battery. The 14500 is generally referred to as a lithium-ion battery.
