At present, whether the battery is a lithium iron phosphate battery, a ternary battery, or a lithium titanate battery can not be separated from the battery protection circuit board, someone asked why use a protection board? Wouldn't it save a lot of money not to use a protective plate? Customers who think this way are not surprised, because they do not understand lithium batteries, do not understand the characteristics of the battery, if you understand the lithium battery, you will feel that this money can not be saved, this is the last line of defense to ensure the safety of battery products. Lithium batteries have developed rapidly in recent years. Although they have been developed for nearly a hundred years, there are currently no materials that can guarantee that the batteries will not ignite and not explode. All need to add a protection board to protect the battery from overcharging, overdischarging, overcurrent, and short circuits To achieve battery saf...

Lithium-ion battery protection board current selection 1. The lithium-ion battery protection board current is determined by the detection voltage of the protection IC and the internal resistance of the MOS tube. If the protection IC cannot be changed, you can change the MOS tube, such as DW01 and 8205MOS, using a MOS tube is 2 ~ 5A, using two The MOS tube parallel current will double. At present, some large-capacity mobile power supplies use 3 to 4 MOS tubes in parallel. 2. Protection board protection current = overcurrent detection voltage / MOS tube internal resistance (Because two MOS tubes are connected in series, the MOS tube internal resistance must be multiplied by 2) 3. Lithium-ion battery protection board selection depends on the battery capacity. Generally, there are no special requirements for batteries below 2000mAh. Select a general protection board. The protection current is 2 ~ 5A. The discharge current of general batteries is 1C. Battery protection...

As the iPhone is used longer, you will find that its battery life is not as strong as when you first bought it. Although it can still be used, it needs frequent charging. For any user, this is normal. In theory, as long as you turn on the iPhone's battery life is consuming and irreversible. But that doesn't mean we can't do anything about it, and develop good charging habits that will allow your iPhone battery to last one year longer than others. How the iPhone battery works Everyone knows that the iPhone and other digital products are equipped with lithium-ion batteries . Apple says that compared with previous generations of battery technology, lithium-ion batteries charge faster, have a longer life, and have higher power density.  The key factor that determines the life of a lithium-ion battery is the charging cycle. IPhone charging from 0 to 100% is a charging cycle. Assuming your iPhone has an initial charge of 100%, it consumes 75% of it...

How many model names does the lithium battery have? In fact, it's not clear at this time, because each battery manufacturer has its own model specifications and some custom battery models. The following introduces the name of the lithium-ion battery model and the meaning of the letters and numbers on the battery, so that everyone can better understand the battery model specifications. Name of the square battery model: 6 numbers indicate the thickness, width and height of the battery, respectively, in millimeters. When any of the three dimensions is greater than or equal to 100mm, a symbol / should be added between the dimensions; if any of the three dimensions is less than 1mm, the letter "t" is added before this dimension, and the unit of this dimension is one tenth of a millimeter. "I" indicates that there is a built-in lithium ion, and "L" indicates a lithium metal or lithium alloy electrode. The second letter indicates the ...

Lithium-ion battery is an ideal power source due to its high working voltage, small size, light weight, no memory effect, no pollution, small self-discharge, and long cycle life. In actual use, in order to obtain a higher discharge voltage, at least two single-cell lithium-ion batteries are generally used in series to form a lithium-ion battery pack. At present, lithium-ion battery packs have been widely used in various fields such as notebook computers, electric bicycles and backup power sources. Therefore, how to charge the lithium-ion battery pack is very critical. Now I will describe several charging methods commonly used by the lithium-ion battery pack and the most suitable charging method that I think are as follows: 1. Series charging At present, the charging of lithium-ion battery packs generally uses series charging, which is mainly because the series charging method has a simple structure, low cost, and is relatively easy to implement. However, due...

Scientists learn more about the first hours of a lithium-ion battery's life. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come. Now scientists have witnessed the formation of the solid-electrolyte interphase at a molecular level.  This component, known as the solid-electrolyte interphase or SEI, has the crucial job of blocking some particles while allowing others to pass, like a tavern bouncer rejecting undesirables while allowing in the glitterati. The structure has been an enigma for scientists who have studied it for decades. Researchers have tapped multiple techniques to learn more but never -- until now -- had they witnessed its creation at a molecular level. Knowing more about the SEI is a crucial step on the road to creating more energetic, longer-lasting and safer lithium-ion batteries. The work published Jan. 27 in Nature Nanotechnology was performed by an internation...
