In 2018, China turned from a large lithium salt importing country to a lithium salt exporting country Overall, the sharp increase in China's lithium hydroxide exports is on the one hand the release of China's lithium producer capacity, and on the other hand, the rapid growth in demand for lithium hydroxide overseas.

The technical parameters of UPS power supply are important indicators of the quality of UPS and are the main basis for selection For the UPS power supply to be able to supply the load device with clean and uninterrupted power supply, it is necessary to have a detailed understanding of its performance parameters.

First Overview of the situation1.

In the past 2018, many industry people have seen it as a milestone year for the new energy vehicle market In this year, not only the macroscopic traditional car enterprises opened up the electrification transformation layout, the new energy vehicle policies in the two major markets of China and the United States were adjusted, and the sales on the micro level were greatly increased.

Electric vehicle batteries are generally lead-acid batteries, charging time is generally 8 to 10 hours, should not exceed 12 hours

Lithium batteries can also be divided into two types, the cell voltage is 3.7V each 3.2V, of which 3.2V polymer battery is said to be safer than the other.

During the use of polymer lithium batteries , battery bulging may occur due to excessive charging current, overcharging, etc.

In life we all use every day to lithium batteries , such as mobile phones, laptops, 12v electric fish lithium batteries , etc.

Lithium is the most active metal in the world. Lithium-ion batteries are small in size, high in density,

Usually 18650 battery are in parallel to increase capacity, such as 20000mah mobile power is normally provided by a battery 8 or 6 3400mah 2600mah the 18650 battery into.
