The lithium-ion battery core is composed of five parts: positive electrode\negative electrode\separator\electrolyte\case;
The positive active material is lithium cobalt oxide (or other lithium oxides, such as lithium manganate\elemental materials, etc.), the negative electrode is graphite;
The electrolyte is a solution composed of lithium hexafluorophosphate dissolved in a variety of mixed solvents;
The separator is made of PP/PE material;
The outer casing usually has aluminum shell/steel shell/plastic packaging film aluminum plastic;
The 523450AR is an aluminum shell battery core, the main ingredients are lithium cobalt oxide and graphite;
According to the capacity of the battery core , the positive active material may be one or more mixtures of lithium cobalt oxide, lithium manganate and ternary materials. TV battery cellsmobile phone are mainly made of lithium. the cobalt oxide and speakers of the boards are mostly made of lithium manganate.
Is the 3.7V lithium battery charging board reliable?
Theoretically no, because the internal resistance of your 10 batteries is different, and during use the capacity decreases faster or slower. A large capacity battery will charge a low capacity battery, and the battery whose capacity degrades quickly will become part of the load, making the actual input capacity of the battery. pack less than 11000mAh.
The mobile phone battery protection board can effectively prevent overcharging. Generally speaking, the protection circuit board is mainly composed of IC and MOS tubes. Once the battery is fully charged, it will automatically disconnect and no longer charge. In theory On the phoneephone, you can also use the universal charger. You must connect 10 batteries in parallel, and connect the positive and negative output terminals to the two contacts of the universal charger...
We did a similar test, using 4 batteries with a nominal capacity of 1100 mAh (real capacity 1130-1150) Nokia 523450AR cell phone batteries were connected in parallel and the capacity was divided using a test cabinet. After 20 cycles, the actual capacity was between 4500 and 4600 mAh.
Reliable.
3.7V lithium battery is a lithium battery with a nominal voltage of 3.7V and a total voltage of 4.2V. Its capacity ranges from several hundred to several thousand mAh. Generally used in various instruments, test instruments, medical instruments, POS machines, laptops and other products.
