Identifying True and False Lithium Batteries

With the development of people's standard of living, mobile phone, laptop, digital electronic products, camera and camera are widely used in people's daily life. Lithium batteries play an important role for these high-tech consumer products. Most of the electronic products that are sold in the market, used batteries have basically finished switching to NIMH Lithium batteries but there are still some manufacturers imitating Lithium batteries using nickel cadmium and nickel for hydrogen batteries. How to identify the right and wrong lithium battery too?

The following methods are acceptable under non-professional conditions:

1, the same capacity battery lithium battery Nickel Cadmium Batteries feel lighter than nickel hydrogen batteries,.

2, use the battery charger Lithium battery charger. If the battery is Ni MH, the battery and nickel cadmium battery are heated during the charging process. If the temperature is not changed greatly, it is Lithium battery.

3, battery, negative electrode "instantaneous" short circuit, cadmium battery nickel, if still "electric" nickel hydrogen battery, battery "electric" like a lithium battery.

Recharging a battery properly

Connecting the phone to the charger before falling asleep is a routine for many phone users. By doing this, we seem to feel comfortable.

Almost all mobile phones come with a lithium rechargeable battery, which may be damaged by over-discharge or over-discharge due to its chemical nature. Someone can argue why I can't charge my phone all night. This is because most chargers are designed with a protective circuit to prevent overcharging / discharging. But what if the circuit doesn't work?

Here are some things to avoid when charging a battery:

Use a non-standard charger.

The battery does not charge until it is almost empty.

Recharge the battery even when the power is charged.

We recommend that a lithium rechargeable battery is between 45% and 75% of the power level and you can charge it for several minutes at any time.

Long charging hazard and deep charging of the lithium battery

Long charging may cause overload. When the battery is fully charged, the lithium battery or charger will automatically stop charging. Charging the nickel battery charger for 10 hours is not called “turbulence.. In other words, if your lithium battery is full, the charger will have a white charger. And none of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and that the quality will be perfect, so your battery will be in danger for a long time. This is another reason why we refuse to charge for a long time.

On some machines, if you do not remove the charger after charging for a certain period of time, the system will not stop charging, but will initiate the discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly not good for battery life. At the same time, the long charging process takes a long time and usually needs to be done at night. In China's electricity grid, the voltage fluctuates in many places at night, and fluctuates a lot. As mentioned above, the lithium battery is very sensitive, much less resistant to charge and discharge fluctuations than nickel, which creates additional danger.

In fact, the shallow charge is more beneficial for the lithium battery. Only when the power module of the product is calibrated to lithium battery, you need to charge deeply. Therefore, products using a lithium-ion power supply do not need to be trapped in the process and everything is convenient and can be charged at any time.

The right way to charge lithium batteries

In summary, the most important tips for charging and discharging used lithium batteries are:

1. Charge the first three times according to standard time and procedures even for new lithium batteries;

2, when the machine is too low, you should start charging as soon as possible (do not wait until auto shut off);

3. The activation of the lithium battery does not require a special method and the lithium battery is naturally activated during normal use of the machine. If you insist on activating the “first three 12 hour charging method”, it will not actually work.

It is therefore wrong to use single-cell lithium batteries for the full pursuit of the 12-hour ultra-long charge and for automatic shutdown. If you did it the wrong way, please correct it in time, perhaps it is not too late.

Introduction and classification of lithium batteries

A lithium battery is a type of battery that uses a lithium metal or a lithium alloy as a plate material and uses a non-aqueous electrolyte solution. Because of the very active chemical properties of lithium metal, lithium metal is difficult to process and store. The cost of production is relatively high, so lithium batteries have not been widely used for a long time. Until recent years, with the continuous maturation and commercial scale production of lithium-ion compound and lithium battery separator technology, the cost has been greatly reduced due to light weight, large capacity, long life and lack of pollution. Lithium batteries will gradually replace lead-acid batteries and will become the main products. Power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aviation and various mobile power supplies, mobile phone power supplies, various emergency lights, flashlights, razors, cameras, cameras, photovoltaics. Street lamps and so on.

Lithium batteries are divided into two types: liquid lithium batteries, a lithium battery, a polymer lithium battery in which a lithium battery adopts a winding structure and has two types of a polymer lithium battery. The structure of lithium batteries is divided into two categories: split winding and stacked. The lithium battery structure then consists essentially of five large blocks: positive electrode, negative electrode, electrolyte, diaphragm, outer housing, and electrode cable.

The wound positive electrode film, separator and negative electrode film are placed sequentially and wound into a cylindrical shape or a flat cylindrical shape and are mainly represented by SANYO, TOSHIBA, SONY and ATL. The stacked type is stacked in multiple layers such as a positive electrode, a separator, a negative electrode, a separator and a positive electrode. All positive electrodes are welded together and the negative electrodes are welded together, mainly represented by ATL.

What is the structure and composition of a lithium battery?

With the development of technology, lithium batteries have also made great progress and are becoming more widely used. In fact, the structure of lithium batteries is divided into two categories: split winding and stacked. The lithium battery structure then consists essentially of five large blocks: positive electrode, negative electrode, electrolyte, diaphragm, outer housing, and electrode cable.

Lithium batteries are then divided into two types of lithium batteries, one lithium battery, one lithium battery, wherein the lithium battery uses the winding structure and the polymer lithium battery has two.

The wound positive electrode film, separator and negative electrode film are placed sequentially and wound into a cylindrical shape or a flat cylindrical shape and are mainly represented by SANYO, TOSHIBA, SONY and ATL. The stacked type is stacked in multiple layers such as a positive electrode, a separator, a negative electrode, a separator and a positive electrode. All positive electrodes are welded together and the negative electrodes are welded together, mainly represented by ATL.

The lithium battery materials currently used are lithium cobaltate, lithium nickelate and lithium manganate. The most commonly used material is lithium cobaltate, which has good cycle performance and is easy to manufacture. The disadvantage is that cobalt compounds are more expensive. Because of its unstable nature, lithium nickel is difficult to produce. It is generally used as a nickel cobalt doped nickel compound, also known as lithium nickel cobaltate. Lithium manganate is also a very good material, and at high temperatures, the decomposition of lithium manganate is relatively rapid, and many other causes are still in the laboratory stage.

How to dispose of batteries

Remove a battery immediately when it runs out; otherwise it may leak.

Do not put it in your pocket as it may cause it to break. Instead, place the battery in a container.

Do not store used batteries together. Although a battery can no longer run a toy or game, there may still be a small amount of power left.

If several batteries malfunction, they may charge and even emit fire.

Do not mix old and fresh batteries. Batteries can ignite, explode or leak, which can damage you as well as the device in which the batteries are installed.

Since many types of batteries are considered household waste, you should follow the correct guidelines for disposal. Most hazardous waste days are also mentioned in the local newspaper. Most normal alkaline batteries are not considered hazardous waste and may be disposed of in normal household waste. However, for other batteries, such as lithium, mercury, oxide, nickel-cadmium, nickel metal hydride, and silver oxide, it is best to be careful and follow your city's battery recycling guidelines. Batteries contain elements that can infiltrate the soil, which is dangerous to the environment. In most cases, the batteries can be brought to your local recycling center at any time, or they can be collected on your city's designated household waste disposal days.
