Lityum batareyalar va batareyalar o'rtasidagi farq nima?
Cell refers to a single electrochemical cell containing positive and negative electrodes, which is generally not used directly. Different from the battery contains protection circuit and shell, can be used directly. Cells are divided into three types: aluminum shell cells, soft-coated cells (also known as "polymer cells"), and cylindrical cells. Usually mobile phone batteries use aluminum shell cells, digital products such as Bluetooth use soft-packed cells, and laptop batteries use a series-parallel combination of cylindrical cells.
Lityum batareya asosan ikkita qismdan iborat, batareya xujayrasi va himoya paneli PCM (quvvat batareyasi odatda batareya boshqaruv tizimi BMS deb ataladi), himoya paneli asosan himoya chipi (yoki boshqaruv chipi), MOS trubkasi, rezistor, kondansatör va PCB platasidan iborat. , va hokazo. Batareya xujayrasi lityum batareyaning yuragiga teng, boshqaruv tizimi esa lityum batareyaning miyasiga teng. Batareya xujayrasi asosan musbat elektrod materiali, salbiy elektrod materiali, elektrolitlar, diafragma va qobiqdan iborat.
Batareya xujayrasi lityum batareyalar yig'ilishining muhim qismidir. Ko'pincha lityum batareyaning batareya xujayrasi, boshqaruv (himoya) birligi va tashqi korpusdan iboratligi aytiladi, shuning uchun o'lchamning boshqacha bo'lishi odatiy holdir. Batareya xujayrasi yarim tayyor mahsulot bo'lib, uni to'g'ridan-to'g'ri batareya sifatida ishlatib bo'lmaydi. U faqat quvvatni ta'minlash uchun ishlatiladi. Tayyor akkumulyatorni hosil qilish uchun himoya sxemasi va korpus paketi bilan jihozlangan bo'lishi kerak.
