Lithium battery is mainly composed of two major pieces, the battery cell and the protection plate.
The cell is equivalent to the heart of the lithium battery, and the management system is equivalent to the brain of the lithium battery.
Mainstream battery cell brands:
Imported battery cell suppliers: SONY, SANYO, PANASONIC, LG, SAMSUNG
The first-line domestic battery cell suppliers: LISHEN, BAK, BYD, ATL, etc..
The second-line domestic battery cell suppliers: HUAYUEBAO, CHAM, HAOPENG, DLG, YIKLIK.
Mainstream protection IC suppliers:
Hardware protection: Japanese system: Seiko, Ricoh, Meiji, Mitsubishi; Taiwan system: Neotec, Fortune.
Software protection: America system: Texas Instruments, Maxim; Japanese system: SONY, Mitsubishi; Taiwan system: 02, ATMEL.
Main structural components of lithium-ion batteries:
Positive materials (lithium cobaltate, lithium manganate, lithium iron phosphate, lithium nickel cobalt manganate, lithium nickel cobaltate, etc. and their mixtures)
Negative electrode materials (artificial graphite, modified natural graphite, etc.)
Diaphragm material (polyethylene film, polypropylene film or a composite of both)
Electrolyte (EC, PC, DEC, DMC, EMC and other solvents and lithium hexafluorophosphate formulated solution)
Positive and negative terminals (positive and negative lugs)
Shell (steel shell, aluminum shell, aluminum-plastic film)
The protection board mainly consists of protection chip (or management chip), MOS tube, resistor, capacitor and PCB board.
