Battery Manufactory

The 14500 battery is a lithium battery with a diameter of 14mm and a height of 50mm. It is divided into lithium iron phosphate battery and lithium cobalt oxide battery according to the core material. The lithium cobalt oxide battery voltage is 3.7V, and the lithium iron phosphate battery voltage is 3.2V. The voltage can be adjusted to 3.0V by the lithium battery regulator. Since its size is the same as that of the AA5# battery, one 14500 lithium battery and one occupancy barrel can be used instead of two AA batteries. Compared with nickel-metal hydride rechargeable batteries, lithium batteries have the advantages of light weight, less self-discharge and superior discharge performance. Therefore, they are widely used by digital photographers and electronic cigarettes instead of nickel-metal hydride rechargeable batteries. Comparison of advantages and disadvantages： Lithium cobaltate is currently the most widely used cathode material for lithium ion batteries. It

18650 is the originator of lithium-ion battery--a standard lithium-ion battery model that Japan SONY Company set in order to save cost, 18 of which means diameter is 18mm, 65 means length is 65mm, 0 means cylindrical battery. The common 18650 battery is divided into a lithium ion battery and a lithium iron phosphate battery. The lithium-ion battery voltage is 3.7V, the charge cut-off voltage is 4.2v, the lithium iron phosphate battery has a nominal voltage of 3.2V, the charge cut-off voltage is 3.6v, the capacity is usually 1200mAh-3350mAh, and the common capacity is 2200mAh-2600mAh. 18650 lithium battery applications The 18650 battery life theory is cyclic charging 1000 times. Due to the large capacity per unit density, most of them are used in laptop batteries. In addition, the stability of the 18650 is very good at work. It is widely used in various electronic fields: it is often used in high-end glare flashlights. Power, wireless data transmitters, electric

Research by the GGII shows that the global smartphone and tablet device market is saturated, and shipments have continued to decline slightly since 2016. In 2018, shipments of small wearable devices, smart homes, instrumentation equipment, etc. continued to maintain a compound annual growth rate of more than double digits, becoming a relatively high growth rate 3C digital terminal market. According to the specific data, 2018 China's digital lithium battery shipments were 31.8GWh, down 0.8% year-on-year, of which mobile phone lithium battery demand fell the most, down 12.9%; including small wearable devices, smart home, electronic cigarettes, instrumentation The demand for lithium batteries in other equipment rose against the trend, with an increase of 16.8%. Aiming at this subdivided market, small and medium-sized polymer lithium-ion battery companies are rushing in, but there are very few successful breakthroughs. The reason is that on the one hand, the tec

After the iPhone 11 series was officially released, a group of users have already got a new machine. However, some iPhone 11 Pro users have found a fault: using Apple's original 18W fast charge, the battery can only be charged to 80%. There are also some user feedback, my iPhone 11 Pro with Apple's original charger, charged for 3 hours is not full. Finally, in desperation to take the after-sales test, the results found to be normal. In fact, the iPhone 11 Pro can only charge up to 80% is not a malfunction, because the "Optimize Battery Charging" feature is not turned off. As we all know, when the power of Apple's mobile phone is less than 80%, the iOS system will let the CPU run down in order to ensure the safety of the battery. At this time, the user may feel the card. Since the lithium battery is fully charged and discharged for about 500 times, the battery is basically unable to meet the needs of the Apple mobile phone. In addition, th

The panic that caused the explosion of mobile phones has always left people with a lingering after the past, including global brands such as Dell and Apple. This makes people have to consider a question: Is the explosion of lithium batteries inevitable? Mobile phones, notebooks, etc., the so-called lithium-ion battery is the device that relies on the movement of lithium ions between the positive and negative electrodes to realize the supply and release of electricity. It requires that lithium ions can not be attached to other factors when shuttle between the positive and negative electrodes, that is, clean movement. In theory, this design is completely achievable, but in practice, because lithium-ion batteries are extremely sensitive products, any abnormal situation may cause problems in the battery. All lithium battery explosions are caused by short circuits. The phenomenon of short circuit is overcharge, over discharge, overcurrent, and overheat. They are sho

The polymer lithium battery is a chemical battery with high energy, miniaturization and weight reduction. Lithium battery charging methods are a topic that many people are paying attention to because lithium battery charging methods are different for different lithium batteries. How polymer lithium batteries work 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 polymer lithium battery uses a ruthenium alloy as a positive electrode, and uses a

For the lithium battery repair and repair technology, everyone may have doubts, because everyone feels that the lithium battery performance is weakened, the stroke is attenuated, the charge can not be charged, and so on. As long as the battery appears, it can no longer be used. This idea is a big mistake, because the lithium battery is not only repairable, but the repair performance can be restored by more than 90%. Mobile phone lithium battery repair method 1. Use a clean eraser or other cleaning tool to gently wipe the metal contacts on the lithium battery and the metal contacts on the phone to help with the charging status and power lasting. 2. The old mobile phone lithium battery that will be automatically shut down will be wrapped tightly with plastic wrap. When wrapping, try to serve as much as possible. There are three layers inside and outside to ensure that the battery is in a vacuum state. Then, the three-layer newspaper on the outside of the plastic
