What is the li-ion  battery?

 

Everyone knows a little bit about batteries. Although lithium batteries are a new type of battery in the battery industry, li-ion batteries are one of the typical representatives of lithium batteries.

What does li-ion  battery refer to?

li-ion battery refers to a lithium battery that uses lithium nickel cobalt manganese or lithium nickel cobalt aluminate as the positive electrode material. There are many kinds of positive electrode materials for lithium ion batteries, mainly lithium cobalt oxide, lithium manganate, Lithium nickelate, li-iom materials, lithium iron phosphate, etc. The most commonly used household battery is generally the AA battery, its model is 14500, which translates to a cylindrical battery with a diameter of 14mm and a length of 50mm; in simple terms, a battery with a li-ion material as a positive electrode is compared to a lithium cobalt oxide battery. The safety is high, but the voltage is too low, and when used on a mobile phone (the cut-off voltage of the mobile phone is generally around 3.0V), there will be an obvious feeling of insufficient capacity. At present, the former is used more on the market.

The results show that the li-ion battery has the characteristics of high energy density, no memory, and long service life. 

1. The capacity of the li-ion battery is very large. The capacity of the 18650 lithium battery is almost equal to that of the 18650 lithium battery. The li-ion polymer battery can even reach 10,000 mAh.

2. The longer the service life, the longer the service life, and the longer the cycle of using  lithium-ion batteries, which is more than 500 times that of the normal cycle system and more than twice that of rechargeable batteries.

3. The 18650 rechargeable battery has no memory, the remaining battery may not necessarily be discharged before charging, and the application is more convenient.

4. The internal resistance is small, and the irreversible volume damage is small, which can greatly reduce the power consumption of the rechargeable battery itself and improve the battery life.

5. The safety factor of the li-ion polymer lithium battery is high, and it is not easy to cause explosion or environmental pollution. The test data shows that due to the separation of the positive and negative poles of the li-ion lithium battery, the probability of short-circuit failure is in most cases. When the situation drops to the best condition, the protective plate of the polymer battery cell can repair the li-ion lithium battery. On the one hand, it can prevent the rechargeable battery from overcharging or power loss.

What is the application of li-ion lithium battery?

li-ion battery is more perfect and stable worldwide, and its market share is also the leading technology of other lithium-ion products. It has been widely used in the field of small and medium-sized lithium batteries such as consumer digital electronic products, industrial equipment, and medical instruments, and is used in intelligent robots. , AGV logistics vehicles, drones and new energy vehicles and other power lithium battery fields, as well as digital products (smartphones, tablets, laptops, electric toy cars, MP3\/MP4, headsets, mobile phone charging treasures, aircraft model aircraft, mobile Chargers, etc.) showed strong development potential.

The performance role of  li-ion battery

The material with relatively balanced capacity and safety has better cycle performance than normal lithium cobalt oxide. In the early stage, its nominal voltage is only 3.5-3.6V due to technical reasons, and its use range is limited. With the continuous improvement of the formula and structure Perfect, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide batteries.

PLMEN has focused on battery manufacturing technology for 20 years, safe and stable, no explosion hazard, strong endurance, long-lasting power, high charging conversion rate, non-hot, long service life, durable, and has production qualifications. The products have passed countries and parts of the world. Item certification. It is a battery brand worth choosing.
