Ukuqulunqwa kweibhetri ye-lithium

Ukubunjwa kwezinto zeebhetri ze-lithium ikakhulu kubandakanya izinto ezilungileyo ze-electrode, izinto ezingalunganga ze-electrode, izahluli, i-electrolytes, kunye ne-casings.

1. Phakathi kwezinto ezintle ze-electrode, izinto ezisetyenziswa ngokuqhelekileyo ziyi-lithium cobaltate, i-lithium manganate, i-lithium iron phosphate kunye nezinto ze-ternary (i-polymers ye-nickel, i-cobalt kunye ne-manganese).Izinto eziphathekayo ze-electrode zibala umlinganiselo omkhulu (umlinganiselo wobunzima bezinto ezintle kunye ne-negative electrode yi-3: 1 ~ 4: 1), kuba ukusebenza kwezinto ezintle ze-electrode kuchaphazela ngokuthe ngqo ukusebenza kwebhetri ye-lithium-ion, kunye ixabiso layo likwachaza ngqo ixabiso lebhetri.
2. Phakathi kwezinto ezingalunganga ze-electrode, igraphite yendalo kunye negraphite eyenziweyo okwangoku zezona zinto zibalulekileyo ze-electrode.Izinto ze-anode eziphononongwayo ziquka i-nitrides, i-polyaspartic acid, i-tin-based oxides, i-tin alloys, i-nano-anode materials, kunye nezinye iikhompawundi ze-intermetallic.Njengenye yezinto ezine eziphambili zeebhetri ze-lithium, izinto ezingalunganga ze-electrode zidlala indima ebalulekileyo ekuphuculeni umthamo webhetri kunye nokusebenza komjikelo, kwaye zisembindini wokufikelela okuphakathi kwishishini lebhetri ye-lithium.
3. Izixhobo ze-diaphragm ezibhekiselele kwimarike ubukhulu becala ziyi-polyolefin diaphragm, ezenziwe ikakhulu nge-polyethylene kunye ne-polypropylene.Kwisakhiwo somhluli webhetri ye-lithium, i-separator yenye yezinto eziphambili zangaphakathi.Ukusebenza kwesahluli kumisela ubume be-interface kunye nokuchasana kwangaphakathi kwebhetri, echaphazela ngokuthe ngqo umthamo, umjikelo kunye nokusebenza kokhuseleko lwebhetri.Isahluli esinentsebenzo egqwesileyo sidlala indima ebalulekileyo ekuphuculeni ukusebenza ngokubanzi kwebhetri.
4. I-electrolyte ngokuqhelekileyo yenziwe nge-high-purity organic solvents, i-electrolyte lithium salts, izongezo eziyimfuneko kunye nezinye izinto eziluhlaza kumlinganiselo othile phantsi kweemeko ezithile.I-electrolyte idlala indima yokuqhuba i-ion phakathi kwe-electrode efanelekileyo kunye ne-negative yebhetri ye-lithium, isiqinisekiso sombane ophezulu kunye namandla athile aphezulu ebhetri ye-lithium ion.
5. Isingxobo sebhetri: sahlulwe saba yicasing yentsimbi, i-aluminium casing, i-nickel-plated iron casing (yeebhetri zecylindrical), ifilimu ye-aluminiyam-plastiki (ipakishwe ethambileyo), njl. ibhetri
6. Umgaqo wokusebenza kwebhetri
7. Xa ibhetri ihlawuliswa, i-ion ze-lithium ziveliswa kwi-electrode efanelekileyo yebhetri, kwaye i-lithium ion eveliswayo ihambela kwi-electrode engafanelekanga nge-electrolyte.Isakhiwo sekhabhoni ye-electrode engafanelekanga ineepores ezininzi, kwaye i-lithium ion ifikelela kwi-electrode engafanelekanga ifakwe kwi-micropores ye-carbon layer.I-ion ye-lithium eninzi ifakwe, ukuphakama kwamandla okutshaja kuya kuba.Xa ibhetri ikhutshwe, i-lithium ion efakwe kwi-carbon layer ye-electrode engathandekiyo iphuma kwaye ibuyele kwi-electrode efanelekileyo.I-lithium ion eninzi ebuyela kwi-electrode efanelekileyo, iphezulu umthamo wokukhupha.Ngokuqhelekileyo, umthamo wokukhupha ubhekisela kumandla okukhutshwa.Ngexesha lokutshaja kunye nokukhupha inkqubo yebhetri ye-lithium, i-lithium ion ikwimo yokunyakaza ukusuka kwi-electrode efanelekileyo ukuya kwi-electrode engalunganga.Ukuba umfanekiso webhetri ye-lithium uthelekiswa nesitulo esishukumayo, iziphelo ezibini zesitulo esishukumayo zii-electrode ezilungileyo kunye ne-negative yebhetri, kwaye i-ion ze-lithium zifana neimbaleki, zibaleka zibuyela emva naphambili phakathi kweziphelo zombini zesitulo esishukumayo. .Ke iibhetri ze-lithium zikwabizwa ngokuba ziibhetri zesitulo sokugungqa.
