Is there a difference between a 14500 battery and a number 5 battery?

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

2, AA14500 nickel-metal hydrogen voltage is 1.2 volts, full up to 1.4 volts. The 14500 lithium voltage is 3.7 volts and reaches 4.2 volts after full charge. Battery No. 5 is labeled 1.5 volts and the voltage is reduced to about 1.1 volts.

3, each has its own application, can not replace each other.

Battery number 5 is the same size as battery number 14500.

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

Batteries No. 5 are generally referred to as disposable batteries or nickel-metal hydride nickel-cadmium batteries. 14500 is generally referred to as lithium ion batteries.

It is a lithium battery with a diameter of 14mm and a height of 50mm. It is divided into a lithium iron phosphate battery and a lithium cobalt acid battery according to the core material. Lithium cobalt acid battery voltage 3.7 V, lithium iron phosphate battery voltage 3.2 V. The voltage can be adjusted to 3.0 V. by using a lithium battery regulator. Since its external size is the same as that of an AA 5 # battery, a 14500 lithium battery and a seat bucket can be combined to replace two AA batteries. Compared with nickel-metal hydride charging batteries, lithium batteries have the advantages of light weight, low self-discharge, and superior discharge performance. Therefore, they are widely used by photography enthusiasts in digital cameras and electronic cigarettes instead of nickel-metal hydride charging batteries.

Lithium cobalt acid

Lithium cobalt acid has a nominal voltage of 3.7 V.

Lithium iron phosphate

The nominal voltage of lithium iron phosphate is 3.2 V, which is more suitable for replacing the No. 5 battery for digital cameras.

Comparison of advantages and disadvantages

Lithium cobalt acid is the most widely used lithium ion battery positive electrode material, mature technology, with structural stability, high specific capacity, outstanding comprehensive performance and other advantages; The disadvantages are poor safety and high cost, and are mainly used for small and medium-sized electric cores.

lithium iron phosphate is a new type of lithium ion battery cathode material that has the advantages of good safety, no explosion, and good recycling performance (up to 2,000 times), but its energy density is much lower than that of lithium cobalt phosphate and ternary materials. More suitable for electric vehicles, electric tools and other fields.
