If you don't do it right, you will become African! The battery modification process is not very complicated, but it is dangerous. The cutout of the battery contact points is very special! There is also the polishing of the insulating paint. The most dangerous step is the connection of the positive and negative stages. If you connect the wrong battery, it will get hot! May cause an explosion. And voltage stability. It is therefore recommended not to modify it yourself! You can buy two more professional ones

How to make mobile phone batteries
If you follow the formal process The production process of original cell phone batteries is more complicated, but usually custom-made batteries just use ready-made cells, morea box and some simple protection circuits. Most custom cell phone batteries are unreliable. So, if you are interested in battery production, you can go to domestic cell phone battery manufacturers, such as well-known commercial battery manufacturers such as Hony Battery, to research. However, 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 sized battery cell, puis to place 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 material are cell phone batteries made of?
1. Types of lithium batteries:
Secondary batteries currently used in the market mainly include nickel metal hydride. There are two types: (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 must be 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 batterieshave been around for a long time, but lithium is a very active metal (remember its position in the periodic table of elements? It is not very safe to use and often burns and explodes while charging. Later they were 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 electrodee and an electrolyte. As a battery type, lithium-ion batteries also have all three of these elements. Typical lithium-ion technology uses liquid or inorganic colloidal electrolytes and therefore requires a robust casing to contain the flammable active ingredients, which increases the weight and cost of batteries and also limits the flexibility of their 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 more of the three main structures.
The new 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 n No matter what shape, greatly the flexibility of the designeption of battery shape is improved, so that batteries of any shape and capacity can be manufactured 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 sold on the market can easily cause the safety valve to rupture and catch fire when overcharged. This is very dangerous, so a protective IC circuit must be installed to ensure this. that the battery will not be overcharged. When it comes to lithium-ion polymer batteries, this type of battery has bettercharge and discharge resistance characteristics than liquid lithium ion batteries, so the requirements for external protection IC circuits can be appropriately relaxed. 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 tended to use lithium-ion batteries in recent years, major manufacturers global mobile phone companies still have a choice. has its own characteristics and habits. For example, in the same historical period:
Nokia: uses Ni-MH (nickel metal hydride) batteries, LiB (liquid lithium-ion) batteries, but nots LiP (Rd). .
Ericsson: uses Ni-MH batteries, LiB batteries and LiP batteries.
Motorola: uses Ni-MH batteries and LiB batteries, but does not use LiP batteries.
It is not difficult to see that Ericsson has demonstrated its true pioneering nature in mobile phone technology by selecting the first lithium-ion polymer LiP battery for mobile phones. According to the information I found, the current major manufacturers of lithium-ion polymer batteries 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 reachingthe level required by all cell phone manufacturers. It will take time for it to become popular among products and be widely used.
On the other hand, although lithium-ion batteries have many advantages, they also have disadvantages, such as high price and low number of charge and discharge cycles. 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. I'm talking about the cost price of semi-finished products
Please accept it, thank you!
How to makea lithium. battery for your cell phone
Buy a lithium battery and write “handmade”!
It's really dangerous and easy to explode. Just use the method I told you, haha!
How to make a cell phone battery
If you want to make a cell phone battery according to your own preferences, you can find a simple method for making a cell phone battery on the Internet , but the mobile phone battery produced in this way It cannot be used for mobile phones. In terms of production costs, it is better to buy a mobile phone battery. Nowadays, domestic mobile phone batteries are very cheap and the quality is relatively. reliable. Professional batteries from well-known brands such as Hony home batteries are economical and affordable. Most usersrs use them much safer than manufactured batteries.
How to make a cell phone battery and what tools are used to make it?
You can go to a place specifically equipped with batteries to obtain a battery.
Can you make your own cell phone battery?
Buy lithium battery cells on Taobao and weld the protection circuit yourself when you return.
Can you make your own mobile phone battery?
Yes, you can just go to a place that specializes in making cell phone batteries and make one. This way the standby time will be longer and the quality will be much better!
How to make a universal cell phone battery?
It is too complicated to make and cannot be used. You can consider Deji batteries. EThey have a large capacity and are about the same price as the original ones but much cheaper, haha z636363.
Who can make their own electric batteries? Who knows how to use 18650 lithium batteries to make electric vehicle batteries? What hardware and other circuit boards are needed to make them? Know how to respond
in two ways.
First, disassemble the MP3 and replace the lithium battery inside. If you want it to look good, you can only choose one of the same size, and you can replace it with a larger capacity one.
Second, if the MP3 has an external data line for charging, you can use the emergency power output to connect to the MP3; the capacity of the backup power varies from a few hundred to several thousand mAh; which is quite sufficient.
To put it simply, youneed to buy two things first: for 48V, it is a 13 cell lithium battery protection board, then a batch of 18650 batteries.
The string of 13 verses is 48V, then you calculate your needs, a single cell is around 2000 mAh, I estimate you need at least 8 and reach 16A.
The total number of piles is 104!
There are many welding videos on the Internet, which are a little difficult for ordinary people. You can choose a soldering iron to connect this huge battery.
