How to repair lithium battery properly

Lead-acid batteries are safe, durable and low cost, making them suitable for civilian use. There are many types of lead-acid batteries. There are electric vehicles for electric vehicles, batteries for UPS, and batteries for starting batteries. You can choose the right lead-acid battery according to your field of use. It cannot be mixed. The functions are different. Life in the field can be greatly affected.

General warranty for one year, your battery is your own for a long time, there is dormancy, you need to charge the charger with the electrolyte, about 5-6 hours can be used, the dry battery is added within about 90 days after leaving the factory The electrolyte can be used after standing for half an hour, but it takes a long time to activate.

A lead-acid battery (VRLA) is a battery whose electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. When the lead-acid battery is charged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the discharge state, the main components of the positive and negative electrodes are lead sulfate. A single-lead lead-acid battery has a nominal voltage of 2.0V, can be discharged to 1.5V, and can be charged to 2.4V. In applications, 6 single-cell lead-acid batteries are often used in series to form a 12V lead-acid battery. There are also 24V, 36V, 48V and so on.

It may be that I have a shallow understanding, I really have never heard of an alumina battery. Lead-acid batteries are safe, durable and low cost, making them suitable for civilian use. There are many types of lead-acid batteries. There are electric vehicles for electric vehicles, batteries for UPS, and batteries for starting batteries. You can choose the right lead-acid battery according to your field of use. It cannot be mixed. The functions are different. Life in the field can be greatly affected.

Lithium-ion batteries have electrolytes, which are relatively unsafe. Lithium-polymer batteries use polymer electrolytes, which have long service life and safety, and do not cause safety hazards such as expansion and packaging. Therefore, polymer batteries are definitely better.

Lithium polymer battery

Lithium-ion batteries are classified into liquid lithium-ion batteries and polymer lithium-ion batteries or plastic lithium-ion batteries according to the electrolyte materials used in lithium-ion batteries. The positive and negative materials used in the polymer lithium ion battery are the same as the liquid lithium ions. The positive electrode material is divided into lithium cobaltate, lithium manganate, ternary material and lithium iron phosphate material, and the negative electrode is graphite. The working principle of the battery is also basically Consistent.

The main difference is that the electrolyte is different. The liquid lithium ion battery uses a liquid electrolyte, and the polymer lithium ion battery is replaced by a solid polymer electrolyte. The polymer can be either "dry" or "colloidal". Most of the current polymer gel electrolytes are used.

Lithium battery

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S. Whittingham proposed and began researching lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the main

Lithium polymers have a long service life.

700-800 hundred times of complete power is only theoretical data, now the use of intelligent machines, normally 300 or so will be very serious attenuation, there are many software on the Internet to detect the actual capacity of the battery you can use it to see the situation of your battery .

[Expanding information]

The basic structure of modern batteries includes three elements: positive electrode, negative electrode and electrolyte. As a kind of battery, a lithium ion battery also has these three elements. In general, lithium ion technology uses a liquid or inorganic colloidal electrolyte, so a strong outer casing is required to contain the flammable active ingredient, which increases the weight and cost of the battery, and also limits the size and shape flexibility. In general, the minimum thickness of a liquid lithium ion secondary battery is 6 mm, which is more difficult to reduce.

The so-called polymer lithium ion battery uses at least one or more of these three main structures as a main battery system.

A new generation of polymer lithium-ion batteries is already highly polymerized, so the shape can be thinned (thinest 0.5 mm), arbitrarily aread and arbitrarily shaped, greatly improving the flexibility of battery design. Sex, so that it can be combined with the product requirements to make batteries of any shape and capacity. At the same time, the unit energy of polymer lithium-ion battery is 50% higher than the current general lithium-ion battery, and its capacity, charge and discharge characteristics, safety, operating temperature range, cycle life and environmental performance are larger than lithium-ion batteries. Increase in range.

The secondary batteries currently used on the market mainly include nickel-hydrogen (Ni-MH) and lithium ion (Li-ion). Lithium-ion batteries are available in liquid lithium-ion batteries (LiB) and polymer lithium-ion batteries (LiP). So in many cases, the Li-ion on the battery must be a lithium-ion battery. But not necessarily a liquid lithium-ion battery, it may also be a polymer lithium-ion battery.

Lithium-ion batteries are an improved version of lithium batteries. Lithium batteries have been around for a long time, but lithium is a highly active metal (remember its position in the periodic table?), it is not safe to use it often burns and bursts when charging. In the situation, there will be a modified lithium-ion battery, which incorporates components that inhibit lithium activity (such as cobalt, manganese, etc.), so that lithium battery is truly safe, efficient, and convenient, and the old lithium battery is also followed basically eliminated. As for how to distinguish them it can be identified from the identification of the battery, Li battery is Li lithium battery is Li-ion. Nowadays, the so-called "lithium batteries" used in notebooks and mobile phones are actually lithium-ion batteries.

In the case of overcharged liquid lithium ion (LiB) batteries currently on the market, it is easy to cause the safety valve to rupture and cause fire. This is very dangerous, so it is necessary to install a protection IC circuit to ensure that the battery does not over-excess the situation of charging. In terms of polymer lithium-ion batteries and this type of battery has better charge and discharge resistance than liquid lithium-ion batteries, so the requirements for external protection IC lines can be appropriately relaxed. In addition, in terms of charging, the polymer lithium ion battery can be charged by the IC constant current, which can shorten the waiting time compared with the time required for the CCCV (ConstantCurrert-ConstantVoltage) charging method used in the lithium ion secondary battery.

Second, the application of mobile phone manufacturers to lithium batteries

Although almost all manufacturers have tended to adopt lithium-ion batteries in recent years, the world's major mobile phone manufacturers still have their own characteristics and habits for battery selection, such as in the same period of history:

Nokia: Ni-MH (NiMH) batteries, LiB (Liquid Lithium Ion) batteries, and LiP (Polymer Lithium Ion) batteries are not used.

Ericsson: Ni-MH battery, LiB battery, LiP battery.

Motorola: Ni-MH battery, LiB battery, and LiP battery are not used.

It is not difficult to find that Ericsson reflects the true nature of its mobile phone technology pioneer from the earliest use of LiP polymer lithium-ion batteries for mobile phones. According to the information I found, the main manufacturers of polymer lithium-ion batteries are Japan's SONY, Panasonic, GS and other companies. In 2000, the production volume reached 21 million, of which 50% were Ericsson mobile phones. Today, in 2002, lithium-ion batteries have been widely used and popularized on other mobile phone manufacturers. However, in the use of polymer lithium-ion batteries, it is still far from being popularized in all mobile phone manufacturers' products, and it will take time to widely use them.

On the other hand, although lithium-ion batteries have many advantages, they are also defective, such as high price and low number of charge and discharge cycles. Lithium batteries charge and discharge only 400-600 times, and special improvements have been made more than 800 times. Ni-MH batteries can be charged more than 700 times, and some good quality products can be charged and discharged up to 1200 times. In this comparison, nickel-metal hydride batteries have longer life than lithium batteries. In addition, the price of nickel-metal hydride batteries is much lower than that of lithium batteries. And strictly speaking, lithium batteries also have a memory effect, but its memory effect is very low, basically negligible.

From this point of view, there is currently no perfect battery.
