Why Do We Need Lithium Batteries?

The lithium battery is a non-aqueous battery with lithium metal or lithium alloy as anode and cathode materials. Due to the highly active chemical properties of lithium metal, the processing, storage and use of lithium metal have high requirements for the environment. With the development of science and technology in this generation, lithium battery has become the mainstream of production.

What is the development history of lithium battery?

The lithium battery is a non-aqueous battery with lithium metal or lithium alloy as anode and cathode materials. In 1912, Gilbert n. Lewis first proposed and studied lithium metal battery. In the 1970s, Mr. Whittingham who has proposed and began to study lithium-ion batteries. Due to the highly active chemical properties of lithium metal, the processing, storage and use of lithium metal have high requirements for the environment. For the demand of the development of science and technology, lithium battery has become the mainstream.

How to distinguish lithium batteries?

Compare the capacity of a lithium battery. The general nickel cadmium battery is 500mah 600mah, and the nickel hydrogen battery is not more than 800-900mah; The capacity of lithium-ion mobile phone battery is generally between 1300-1400mah, so the service life of lithium battery after full load is about 1.5 times that of Ni MH battery and 3.0 times that of Ni Cd battery. If it is found that the working time of the lithium-ion battery pack you purchased is not published or explained in the manual, it may be forged.

II. Check the plastic surface and materials of lithium battery. Genuine lithium battery has uniform wear-resistant surface and PC material, which is not fragile; The surface of the dummy battery is not wear-resistant or too rough. It is made of recycled materials and is easy to damage.

6. Measure the charging voltage of lithium battery. If nickel cadmium batteries or nickel hydrogen batteries are used to forge mobile phone lithium-ion batteries, they must be composed of five separate batteries. The charging voltage of single battery generally does not exceed 1.55V, and the total voltage of battery pack does not exceed 7.75v.

 When the total charging voltage of the battery pack is lower than 8.0V, it can be nickel cadmium battery or nickel hydrogen battery.

What is the application field of lithium battery?

In the 20th century, with the development of microelectronic technology, the number of miniaturized devices is increasing, which puts forward higher requirements for power supply. lithium battery immediately entered the stage of large-scale application.

The first application is the lithium secondary battery of cardiac pacemaker. Because the self charging rate of lithium battery is very low, the discharge voltage is very low. Cardiac pacemakers can be implanted into the human body for long-term use.

The rated voltage of lithium manganese battery is generally above 3.0V, which is more suitable for integrated circuit power supply. It is widely used in computer, calculator, watch and other fields.

Lithium batteries are widely used in mobile phones, laptops, electric tools, electric vehicles, street lights, navigation lights, household appliances and other fields. This is arguably the largest application group.

The use of lithium batteries has become the market standard, and the demand for lithium batteries is also growing. Shenzhen Sumry Electronics Co., Ltd. has been committed to providing customers with the best quality lithium batteries for many years.
