30 minutes makes you half an expert on lithium-ion batteries.

Because more and more people need to know about the energy storage industry, and batteries are at the heart of energy storage, light technology has put together a simple message for everyone to learn. Battery recycling line I believe that by Reading, you will develop a more professional battery knowledge framework and become a semi-expert. Enjoy your study

First, battery family

The professional name "lithium battery" originally refers to lithium metal battery, which is a kind of battery, lithium battery welding machine but it is no longer used in China because of its explosiveness. Now the so-called lithium battery companies generally use lithium-ion batteries.

The AA and AA batteries we use are the dry ones, the nickel hydride batteries used in the early days of brick phones, the lead-acid batteries used in wheelbarrows, stacked four-by-four, most of the batteries we use in cell phones, laptops and even electric cars are lithium-ion battery.

Second, battery terminology analysis

SOX: The full name is state X, which describes the battery state, mounting machine H is health, C is capacity, P is power, and E is energy, which is a bit like engine parameters, displacement, power, energy, running time and so on. This is the same idea.

SOC refers to the charging of a battery, like water in a bucket. The amount of available power contained in a battery at a given time is called the SOC of the battery at that time. SOC is 0 at full discharge and 1 at full charge. Available capacity actual capacity.

DOD: (depth of discharge) refers to the depth of discharge of the battery. When the battery is full of DOD, the DOD of completely different discharge treatments is 1, so it is a problem between 0 and 1 when the battery passes the DOD under normal circumstances. The relationship between DOD and SOC is: DOD+SOC = 1.

Soh: (State of Health) is the actual battery capacity/initial battery capacity level, which decreases as the battery ages. It is usually measured in terms of capacity and internal resistance

What does flexography mean by mounting?

A crucial step in getting the best print quality is flexographic plate mounting. The best possible performance from the mounting tape during the flexographic printing process can be achieved by following the right procedures for preparation, mounting, and plate removal.
