How to assemble the battery? Battery assembly principle?

How to assemble batteries has become a problem that bothers many people. Battery assembly needs to consider many factors such as battery type, capacity, voltage, etc. Different types of batteries are assembled in different ways. In response to this problem, PHP editor Youzi has compiled the relevant knowledge of battery assembly for everyone, and elaborated on the principles and precautions of battery assembly. Next, let us learn more about how to assemble batteries and master the secrets of battery assembly.

How to assemble the battery?

1. First, let’s understand the positive and negative poles of the battery. The one with “ ” on the battery is the positive pole, and the other end “-” is the negative pole.

2. Then there are the positive and negative poles of the remote control that correspond to the installation. The one with a spring corresponds to the negative pole, and the one without a spring corresponds to the positive pole.

3. When installing, first use the negative terminal of the battery to press the spring to the bottom, and then push the positive terminal of the battery into the battery slot.

4. Once the installation is complete, you can use it normally.

How does the battery assembly work?

Take lithium batteries as an example. The principle is to utilize the movement of lithium ions in the electrolyte to store and release electrical energy. Lithium batteries are composed of four parts: positive electrode, negative electrode, electrolyte and separator. The positive electrode materials generally use lithium cobalt oxide, ternary materials, etc., while the negative electrode materials use graphite, carbon fiber, etc. The electrolyte generally uses polymer electrolyte or organic electrolyte, and the separator is used to isolate the positive and negative electrodes and the electrolyte.

When assembling, first coat the positive and negative electrode materials on copper foil or aluminum foil, and then form the battery core by winding or laminating it; then put the battery core into the battery core casing. The electrolyte is injected and finally the finished battery is packaged.

How to assemble the electric panel battery?

Assembling the electric panel battery requires the following steps: 1. Prepare the battery cells: Select the appropriate battery cells, which can be lithium-ion batteries, nickel-metal hydride batteries, etc. Make sure the battery cells are of good quality and without any damage. 2. Prepare the battery holder: Select the appropriate battery holder according to the number and shape of the batteries. The battery holder can be made of plastic or metal and has the function of fixing the battery cells. 3. Connect the battery cells: Connect the battery cells in series or parallel, and determine the connection method as needed. Use soldering or socket connectors to connect the battery cells together. 4. Internal connection lines: According to the connection method between batteries, use wires for internal connections. Ensure that the connection between each battery cell is safe and reliable. 5. Integrating electrolyte: For some types of batteries, electrolyte needs to be injected into the battery. Follow relevant operating procedures and safety regulations to ensure safe operation. 6. Packaging: Put the assembled battery into an appropriate casing for packaging to ensure the safe use of the battery. 7. Test: After assembly is completed, test the battery to confirm whether its working status and performance are normal. Please note that during the process of assembling electric panel batteries, you need to strictly abide by relevant safety regulations to avoid battery short circuits, overheating and other safety issues. If you are not familiar with battery assembly, it is recommended to ask a professional to do it.

Assemble lithium battery?

Step/Method 1

Lithium batteries are all three layers of lithium ion powder as the positive electrode, and the capacitor paper is the negative electrode separator. They are folded in series, each piece is 1.2V, so a total of 3.6 Or 3.7 volts, use a wire to lead it out and then seal it, add a protective board, and the power will be 42V when enough. ．

Step/Method 2

As long as the battery +- pole is powered, there are two jacks, one positive and one negative output. The jack you are talking about is where the manufacturer presses the battery into the phone and The wire is soldered to the jack post. You only need to plug in the data cable directly to charge. If you take out the battery, the battery has at least three posts, one positive and one negative 4.2V on both sides, and the middle and negative poles have been stepped down. The last 3V is used for mobile phone circuit operation.

Step/Method 3

On the battery, we directly weld two 4.2V wires on the positive and negative pile heads to modify the flashlight, otherwise you cannot fix the output wires. This kind of battery is more difficult to solder. If the spot welding takes a long time, it will easily burn the parts on the protective board. Therefore, only those with welding experience can do it. First, brighten the copper contacts, and then use a sharp soldering iron to quickly (one second) (clock) After spot welding, dip one end of the wiring in tin and weld it close to the pile head. These all refer to lithium batteries packaged in metal cases.

Step/Method 4

There is also a kind of soft packaging that is more convenient for you to weld. You can see the thread ends, and you can directly measure +- with a meter. Spot weld the leads and you can put them to use.

Step/Method Five

The battery with a protective plate can withstand 5V1A charging, because the charger is a switching power supply called constant current and constant voltage. After plugging in, 5V immediately drops to 4.3V. When the battery power rises, the charger's output voltage gradually rises and returns to 5V. When it is balanced, it stops charging.

How to assemble zinc-copper primary battery, easy assembly?

Take a copper sheet and a zinc sheet and connect them to a wire each, add dilute sulfuric acid into the beaker, put the copper sheet and zinc sheet vertically into the beaker, keeping a certain distance apart.

What is the difference between original batteries and assembled batteries?

First of all, most of the cells used in original batteries are imported. For example, the cells of South Korea's LG Sanyo Company are relatively famous. This kind of cells has a relatively high safety factor and has a higher capacity than assembled batteries. Durable and lasts longer.

Generally assembled knock-off batteries are produced by Shenzhen Huaqiangbei. They are made by some small factories. There is no quality guarantee and there are certain safety risks.

How to assemble lithium battery?

Lithium battery assembly method

To assemble a personal lithium battery, you need to prepare tools and batteries, as well as design and calculate the battery with what capacity, voltage, discharge current, etc.

Tips

1. Calculate the battery performance you need

Calculate how many volts the voltage of the battery you want to assemble is, how big the capacity is, and how much the balanced discharge current is. What is the maximum current, discharge end voltage, etc., and based on the relevant battery performance, choose to purchase a suitable battery protection board.

2. Preparation of lithium battery assembly tools

Screwdriver, scissors, voltmeter, ammeter or multimeter, welding tools including solder, welding, flux, etc. That is to say, you need to consider the tools and auxiliary materials that you may use when organizing lithium batteries, which should be more rather than less.

3. Lithium battery selection and corresponding accessories

1) The selection of lithium battery cells, this mainly depends on the purchase of corresponding cell performance based on the time demand for electricity, such as low temperature Environmentally speaking, the choice is a low-temperature battery core. If it is running at high temperature, choose a high-temperature battery core, which is a battery with high current and high rate discharge, even a battery with high rate discharge performance. This is very important. If you choose incorrectly, not only will the assembled lithium battery pack not meet the expected requirements, but it may also cause an accident.

2) Selection of corresponding battery accessories

This is mainly wires and link alloy accessories for battery cells to be connected in series or parallel. The selection of these accessories is based on the assembly and discharge requirements of lithium batteries. , while it can withstand battery discharge requirements, it is necessary to reduce the resistance of the material itself as much as possible to avoid wasting electrical energy.

How to assemble lithium batteries?

First of all, it depends on what kind of battery you are using. If it is a large single aluminum shell battery, it needs to be converted to nickel using a laser welder and a spot welder. If it is 18650, it needs a spot welder and a protective plate. The powerful function of the protection board is software. It can have over-current, over-voltage, over-temperature, over-temperature difference, and over-voltage difference protection. A simple protection board is much cheaper. Lithium batteries must use protective plates, otherwise the pressure difference will be inconsistent, which will affect the life and risk of explosion. If you want to have a long life, try not to use 18650.
