What are the capacity and size of the 14500 lithium battery respectively?

14500 lithium battery means a battery has 14 mm diameter and 50 mm height. According to the batteries material, batteries can be divided into lithium iron phosphate batteries and cobalt acid lithium batteries. Cobalt acid lithium battery voltage is 3.7 V, while lithium iron phosphate battery voltage is 3.2 V. Because of its appearance size is the same as AA5 # battery, one 14500 lithium battery and one placeholder barrel cooperating together can be used instead of two AA batteries. Relative to the nickel metal hydride rechargeable batteries, lithium batteries has light weight, less self-discharge, good discharge performance and other advantages, therefore, they are widely used in digital cameras and electronic cigarettes instead of nickel metal hydride rechargeable batteries by photography fans. Battery life may also good. You need to check electrical appliances as well as the frequency, intensity and duration, and the nominal capacity is 1600 mAh.

Hebei xin dynamics, a leading industry 14500 lithium-ion battery manufacturers according to customer demand customize various specifications of 14500 lithium-ion battery pack. The following simple introduction for you 14500 lithium batteries of three common problem:

1.14500 size problem of choose and buy

Due to the lithium battery voltage (2.5 V - 3.7 V) for discharge or charge will damage the battery, so can protect the battery protection board. I think it's not samples, due to take 14500 battery protection board is higher than ordinary pool 5 a few MM or so, some camera lid, can cover can also camera battery contact plate, in the long run elasticity will decline will cause poor contact. Again a belt * efficiency can't display the battery protection board, because the protection circuit in 2.5 v power, phase opportunity suddenly loses power, does not automatically shut down, may be, thereby causing loss to the camera.

2.14500 capacity problem

Without a protective plate in * voltage total questions that should pay attention to some details:

* the voltage range of the camera, camera commonly voltage of 2.4 V to 4.2 V

So that the opportunity to use voltage to 2.4 V nowadays often shutdown, choose choose the battery in the camera type selection (alkaline, nickel batteries, lithium batteries), choose a different type of battery shutdown voltage is not the same, as long as the selected lithium battery it shut down voltage is 2.6 V. Without the battery protection board for safe voltage of 2.5 V, so there is no discharge problems, but also can make battery energy efficiency.(according to from already the camera)

3.14500 capacity overcharge problem

Lithium battery core overcharge to voltage is higher than 4.2 V, will start to produce side effects. Of charging the higher the pressure, the higher the risk also follow. Lithium batteries voltage higher than 4.2 V, the anode materials within less than half the number of lithium atoms left, store usually break down at this time, let the battery capacity to produce permanent decline. If continue to charge, due to the storage of the cathode has been full of lithium atoms, subsequent anode materials of lithium metal accumulation in the surface. These lithium atoms from lithium ion to the cathode surface to grow in the direction of the dendritic crystal. The lithium metal crystal through the diaphragm paper makes is negative short circuit. Sometimes in short circuit batteries before the first explosion, this is because in the process of overcharge, electrolyte materials can produce gas cracking, such as making the battery shell or blow up pressure valve is broken, and let oxygen in and accumulation in the lithium atoms on the surface of the cathode reaction, then exploded.

Therefore, lithium batteries, be sure to set the upper limit of voltage, can simultaneously to the battery life, capacity, and security.* ideal maximum charging voltage of 4.2 V. Lithium batteries discharge voltage will be lower limit. When the battery voltage is below 2.4 V, part of the material will begin to be destroyed. And because the battery self-discharge, put the more the longer the voltage is low, therefore, discharge * don't to 2.4 V. Lithium battery discharge from 3.0 V to 2.4 V during this period, the release of energy accounted for only about 3% of the battery capacity. Therefore, is an ideal discharge cut-off voltage of 3.0 V. Charge and discharge, in addition to the limit of voltage and current limits can also be necessary. When the current is too large, lithium ions to enter the store, would gather in the material surface.

Because of the continuous development of high and new technology in our country, in the field of batteries, lithium batteries advantages with quickly occupied the market, to become the main force of power market and the energy storage products. The development of lithium battery is inevitable, is currently in the popularity of lithium battery energy storage market has a very wide range. In terms of storage battery, lithium battery both in terms of weight, or lithium batteries from the aspects of volume is comparative advantage.* more in the market now is 18650 lithium-ion batteries, a friend asked how much is the small make up 14500 lithium battery capacity and size respectively, generally down, says a 14500 type to lithium battery capacity sizes, please see below small make up, for example.
