How to make a cell phone battery?

Introduction How to make a cell phone battery? How to Make a Cell Phone Battery If you follow the usual cell phone battery production process, it will be more complicated, but custom-made batteries usually use commercially available batteries.

How to make cell phone batteries

If you follow the usual production process of original cell phone batteries, it is more complicated, but usually custom batteries use ready-made batteries ready to use, plus a box and some A simple protection circuit is enough. Custom-made cell phone batteries like this are mostly unreliable, so if you are interested in battery production, you can go to domestic cell phone battery manufacturers, such as commercial battery manufacturers well known as Hony Battery. , to do some research, but the technology to make your own batteries is not yet mature, so try not to use custom cell phone batteries. I found this information on professional battery websites, hope it can help you.

The process of making a fake cell phone battery

According to professionals, the process of making a fake cell phone battery is very simple. The most important thing is to find a suitable size battery cell, then put the battery cell into the original battery box and connect the wires, then use a soldering iron to connect the wires, and a battery is ready.

What materials are cell phone batteries made of?

1. Types of lithium batteries:

Currently used in the market There are two main types of secondary batteries: nickel-metal hydride (Ni -MH) and lithium-ion (Li-ion). There are two types of mass-produced lithium-ion batteries: liquid lithium-ion batteries (LiB) and lithium-ion polymer batteries (LiP). So, in many cases, if the battery is marked Li-ion, it should begir of a lithium-ion battery. But it is not necessarily a liquid lithium ion battery, it can also be a polymer lithium ion battery.

Lithium ion battery is an improved product of lithium battery. Lithium batteries have been around for a long time, but lithium is a very active metal (remember its position in the periodic table? It's not very safe to use and often burns and explodes while charging. More later , they have been improved). lithium-ion batteries, which added ingredients that could inhibit the activity of lithium elements (such as cobalt, manganese, etc.), making lithium batteries truly safe, efficient and practical, and older lithium batteries also followed suit. As for how to distinguish them, they can be identified by the battery logo. Lithium batteries are Li and lithium ion batteries are Li-ion.Nowadays, “lithium batteries” used in laptops and cell phones are actually lithium-ion batteries.

The basic structure of a modern battery consists of three elements: a positive electrode, a negative electrode, and an electrolyte. As a battery type, lithium-ion batteries also have all three of these elements. Typically, lithium-ion technology uses liquid or inorganic colloidal electrolytes. A strong casing is therefore required to contain the flammable active ingredients, which increases the weight and cost of the battery and also limits the flexibility of size and shape. Generally speaking, the minimum thickness of liquid lithium-ion secondary batteries is 6mm, and it is difficult to reduce it further.

The so-called lithium-ion polymer battery uses polymer materials as the main battery system in at least one or moreeurs of the three main structures.

ShinichiThe current generation of lithium-ion polymer batteries has a high degree of polymerization, so the shape can be thinned (the thinnest is 0.5mm), any area and any shape, which greatly improves the flexibility of battery design, so that batteries are thinner. any shape and capacity can be designed to meet product needs. At the same time, the unit energy of lithium-ion polymer batteries is 50% higher than that of current general lithium-ion batteries. Its capacity, charging and discharging characteristics, safety, operating temperature range, service life and environmental performance are all superior. that those of lithium-ion batteries increase in magnitude.

Liquid lithium-ion (LiB) batteries currently on the market can easilymay cause the safety valve to rupture and catch fire in the event of overload. It is therefore a very dangerous integrated protection circuit. A circuit must be installed to ensure that the battery will not be overcharged. As for polymer lithium ion batteries, this type of battery has better charge and discharge resistance characteristics than liquid lithium ion batteries, so the requirements for external protection IC circuits can be relaxed appropriately. In addition, in terms of charging, lithium-ion polymer batteries can be charged with constant current IC, which can reduce the waiting time compared to the CCCV (Constant Current-Constant Voltage) charging method used in lithium-ion secondary batteries.

2. Application of lithium batteries by mobile phone manufacturers

Although almost all manufacturers have turnedtowards lithium-ion batteries used, but the world's leading mobile phone manufacturers still have their own characteristics and habits when choosing batteries. For example, during the same historical period:

Nokia: Ni-MH (nickel). metal hydride batteries) and LiB (liquid lithium ion) batteries are used, but LiP (lithium ion polymer) batteries are not used.

Ericsson: uses Ni-MH batteries, LiB batteries and LiP batteries.

Motorola: uses Ni-MH batteries, LiB batteries, not LiP batteries.

It is not difficult to see that Ericsson has demonstrated its true nature as a pioneer in mobile phone technology by choosing lithium-ion batteries for the first time LiP polymer for mobile phones. From the information I found, the current major lithium-io battery manufacturersn polymer are Japanese companies such as SONY, Panasonic and GS. The production volume in 2000 reached 21 million units, of which 50% were used in Ericsson mobile phones. Now in 2002, lithium-ion batteries have also been widely used and popularized in mobile phones from other mobile phone manufacturers. However, the use of lithium-ion polymer batteries is far from being popularized in the products of all mobile phone manufacturers, and it will take time for it to be widely used.

On the other hand, although lithium-ion batteries have many advantages, they also have disadvantages, such as high price and difficulty in charging and discharge.The frequency is small and so on. The number of charges and discharges of lithium batteries is only 4...>>

What is needed to make a cell phone battery?How to do? How long will this take?

A diaphragm, a negative electrode piece and a positive electrode piece. This is the exterior of the battery cell with a steel shell and an aluminum shell. The cost of each type is different and the price depends on. the model. The price is generally 1.5-2 yuan. The cost price is about I'm talking about semi-finished products
