Yini i-electrode esebenzayo nenegethivu yebhethri ye-lithium ion? Indlela yesinqumo sebhethri ye-lithium ion evumayo futhi engalungile. Izinto ezivame ukusetshenziswa ezinhle ze-electrode ezivame ukusetshenziswa kumabhethri e-lithium ion, i-lithium manganese acid, i-lithium cobaltate, i-lithium iron phosphate, nezinto ezinobukhulu obuthathu, izinto ezisetshenziswa kakhulu ezingezinhle ze-electrode ezihlanganisa izinto ze-carbon nezinto ezisekelwe ku-silicon, njll. Kumpahla yebhethri ye-lithium ion, i-electrode elungile nengalungile iyingxenye ebalulekile, engaba nomthelela omkhulu ekusebenzeni kwebhethri iyonke.

Ithini i-electrode ephozithivu nenegethivu yebhethri ye-lithium ion? Ngebhethri eliphathekayo, ngokuvamile kukhona i-protrusion iyipali ephozithivu. Njengamanye amabhethri e-elekthronikhi ngokuvamile abhala + i-logo enhle, - bonisa i-electrode engalungile. 1.

Ibhethri ye-lithium-ion positive (i-cathode) i-manganese dioxide iyisici esibalulekile, futhi ukusabela kwamakhemikhali ekushajeni nokukhipha kuyasetshenziswa, futhi ingxenye yokwengeza iwukuthuthukisa ukusebenza kwebhethri. 2, ibhethri ye-lithium-ion negative electrode (anode) yensimbi ye-lithium noma insimbi yayo yengxubevange iyimpahla ye-electrode engalungile, lezi zinto zimbozwe nge-foil yethusi, bese kwenzeka i-electrode engalungile. Manje izinto ezisetshenziswayo zama-electrode ezithengiswayo zibalulekile nge-lithium cobaltate, i-lithium manganate, i-lithium iron phosphate negative electrode material ngokuyisisekelo iyigraphite, kanti i-lithium titanate nayo inhle.

I-tin ingenye yezinto ezingalungile ze-electrode ezisetshenziswa yi-lithium electrode. Inomthamo wevolumu ephezulu, futhi ithathwa njengento engase ibe namandla kakhulu esikhundleni se-electrode engalungile ye-graphite. Njengamanje, izinto ezingezinhle zibalulekile ukuthi zihlukaniswe zibe izigaba ezimbili, i-carbon material yokusetshenziswa kwezohwebo, njenge-graphite yemvelo, i-soft carbon, njll.

, enye isesimweni sokuthuthukiswa, kodwa ithemba lemakethe liyinto enhle engeyona i-carbon negative, Isibonelo, izinto ezisekelwe ku-silicon, izinto ze-alloy, izinto zegolide le-tin, njll. Izinto ezibalulekile ezakha amabhethri e-lithium-ion zifaka i-electrolyte, izinto zokuzihlukanisa, izinto ezinhle nezingezinhle ze-electrode, njll. I-electrode esebenzayo ithatha ngaphezu kuka-40% noma ngaphezulu ezindlekweni eziphelele zebhethri ye-lithium ion, futhi ukusebenza kwempahla ye-electrode ephozithivu kuthinta ngokuqondile izinkomba zokusebenza kwebhethri ye-lithium ion, ngakho-ke impahla ye-lithium electrode ithatha indawo eyinhloko ebhethri ye-lithium ion.

Ibhethri ye-lithium-ion indlela yokunquma ephozithivu nenegethivu 1: 18650 iqhubu lebhethri le-lithium-ion i-electrode ephozithivu, indawo ephansi eyisicaba yi-electrode eyinegethivu. Indlela yesi-2: Indlela yesi-2: Ipeni letafula elibomvu-elimnyama Kukhona ukuphrinta ngocingo kwesikrini sikasilika, esivame ukushiywa. I-18650 Ibhethri ye-Lithium-Ion Indlela Yesinqumo Esibi Enhle 1 Bona umumo, ibhethri yenombolo eshintshiwe ngokuvamile iwumumo wangempela, bheka ukufakwa okuqinisekisiwe kuzo zombili iziphetho, umkhawulo owodwa unendandatho yokucindezeleka, umkhawulo owodwa awunayo, enye iphozithivu, ayikho negethivu; 5, abanye abakhiqizi abalandeli izinga lebhethri, bahlonze ukukhiqizwa, bese kuba isilinganiso sangempela kanye nokubonisana Umkhiqizi, ukucaciswa kwesicelo.

Okungenhla ulwazi olufanele oluhlobene nezinto ze-electrode ezinhle nezimbi ezihlobene nebhethri ye-lithium-ion, ngethemba lokusiza wonke umuntu ukuqonda kangcono.
