What is the size and capacity of the 14500 lithium battery?

Is in 14 mm in diameter, height is 50 mm lithium battery, according to the batteries can be divided into materialLithium iron phosphate batteriesandCobalt acid lithium batteries.Cobalt acid lithium battery voltage of 3.7 V, lithium iron phosphate battery voltage of 3.2 V.By lithium battery voltage regulator voltage can be adjusted to 3.0 v. due to its appearance size is the same as AA5 # battery, 114500 lithium batteriesAnd 1 placeholder barrels to cooperate, can be used instead of two AA batteries.Relative to the nickel metal hydride rechargeable batteries, lithium batteries has light weight, less self-discharge, discharge the advantages of superior performance, therefore be photography fans are widely used in digital cameras and electronic cigarettes, instead of nickel metal hydride rechargeable batteries.

Cobalt acid lithium

Cobalt acid lithium materials of the nominal voltage of 3.7 V

Lithium iron phosphate

Lithium iron phosphate material of the nominal voltage of 3.2 V, is applicable to replace 5 batteries using a digital camera

The advantages and disadvantages compared

Cobalt acid lithium is now the biggest and most common usageLithium ion batteriesThe anode material, mature technology, with stable structure, high specific capacity and comprehensive performance outstanding advantage;Defect is poor security, high cost, it is mainly used for medium and small type batteries.

Lithium iron phosphate is a kind of new lithium-ion battery cathode material, has good safety, do not explode, better cycle performance (up to 2000 times), and other advantages, but its energy density is far lower than the cobalt acid lithium and ternary material.More applicable to electric cars, electric tools, etc.,

Of course there's a difference:

In fact, there are three kinds of size, the performance of different battery: AA14500 nickel metal hydride, lithium electricity, 14500 number 5 dry cell.The difference is:

1, AA14500 nickel metal hydride rechargeable battery.14500 li-ion battery rechargeable battery.5, the battery is not charging the disposable dry cell.

2, AA14500 nimh voltage is 1.2 v, 1.4 v after.14500 lithium-ion battery voltage is 3.7 v, after a full charge of 4.2 volts.5 battery nominal 1.5 v, the voltage drop to around 1.1 v abandoned.

3, each have each use occasions, cannot replace each other.
