Ingabe imboni yebhethri ikuthola kanjani ukulingana phakathi kokuminyana kwamandla nokuvikeleka?

Umbhali :Iflowpower - Umhlinzeki Wesiteshi Samandla Esiphathekayo

Namuhla, izinkampani eziningi ziphishekela ama-monomers aphezulu kanye nokuxineka kwamandla esistimu. Ukuze kuvikelwe ukunikezwa kwamandla amaningi, isixazululo se-electrolytic se-electrolyte ephozithivu nenegethivu ingasetshenziswa kuphela ukususa ukushuba kwe-diaphragm. Ugqinsi lwe-diaphragm yebhethri ye-lithium-ion esikhathini esidlule ingama-microns angu-40, cishe u-12 μm kuphela, uma ifilimu iphukile, futhi imiphumela mibi kakhulu.

Umlilo webhethri we-Samsung Note7 ka-2016 kungenxa yokushoda kwe-diaphragm. Njengamanje, umkhawulo wokuminyana kwamandla wethiyori yebhethri ye-lithium-ion enezinhlangothi ezintathu icishe ibe ngu-350WH/kg-400Wh/kg, kusenezinkinga eziningi zobunjiniyela okufanele zisingathwe. Ngakho-ke, uma kungekho umngane womshado ezintweni ezintsha, ibhethri ingaba phakathi kuka-300WH/kg-400Wh/kg.

Kuphela esimisweni sokufeza ubuchwepheshe bonjiniyela, kungenzeka ukuthuthukisa ukuminyana kwamandla ebhethri le-monomer ku-500WH / kg, futhi kungenzeka ukwandisa ukuminyana kwamandla wephakethe lebhethri ku-260Wh / kg. Kodwa-ke, ukuthuthukiswa nokusetshenziswa kwezinto ezihlukahlukene kufanele kube eminyakeni engu-1-2, ngisho nangaphezulu. Njengamanje, izwe selilungise uhlelo kunokuminyana kwamandla futhi umjikelezo wokuthuthukiswa kwesistimu yebhethri ye-lithium awuhlanganiswa.

Umphumela awukwazi ukuqinisekiswa, okuholela ekuvameni kwezingozi zomlilo. I-EV Century iphinde yaxoxa noMnu. Umbono kaWang Shan wezinkampani eziningi zezimoto wamukele amabhethri e-NCM811.

UMnu. Wang, uthe: Endabeni yokuqinisekiswa okwanele kwesistimu yebhethri, futhi kungabikho ubuchwepheshe besistimu yokulawula ukushisa, lezi zinhlobo zingamabhomu asebenza ngesikhathi ohambweni okukhulunywe ngalo ngaphambili, ngithemba ukuthi inkampani yemoto inganaka. Inkinga yokuphepha kwebhethri ye-lithium enamandla 1.

Ngesikhathi senqubo yokukhiqiza ibhethri. Enqubweni yokukhiqiza, izidingo zokuphepha ziphezulu kakhulu, futhi imboni yamabhethri e-lithium-ion ayizange ibe nengozi, kuhlanganise ne-LG, i-Samsung. 2, ukuhlanganiswa kwephakethe lebhethri.

Amabhethri monomers avezwa ngaphandle, ahlanganise inkinga lapho ibhethri lipakisha. 3, inqubo yokugcina. Kungani inqubo yebhethri ivaliwe, hhayi ukusebenzisa umsebenzisi?.

Ngenxa yokuthi inqubo yokukhiqiza amabhethri e-lithium-ion inzima kakhulu, izinga lamanje, kuhlanganise nezinga lamazwe ngamazwe, lezi zinkampani ezinkulu kunzima ukuzilawula. Kuphela ngenqubo yokuyibeka kuzokwenza kube kubi ukuyibonisa. Inkampani enhle izinsuku ezingu-10-15, phakathi nalesi sikhathi, iphutha elincane liyi-voltage attenuation yebhethri, futhi into enkulu umlilo.

4, ngesikhathi sokuthutha. Ingozi eyodwa iwukuthambeka okude kwebhethri lomkhumbi, amakhilomitha ayi-10-20, izinga lokushisa lesistimu yamabhuleki liphezulu kakhulu. 5, inqubo yokusebenzisa.

Lobu ubudlelwano obuqondile nokushaja. Wonke umgomo weshaja emakethe ugcwele. Lesi simiso sifana nokuthi ngihlezi esitimeleni namuhla ekuseni.

Lapho ukusungulwa kusungulwa ngo-1970, kubizwa ngokuthi ibhethri yesihlalo esinyakazayo. I-ion ihamba iye emuva naphambili ku-electrode ephozithivu kanye ne-electrode eyinegethivu. Inqubo yamanje yokushaja ayinayo indlela yokunciphisa, futhi indlela yokushaja idonsa iyasetshenziswa, hhayi indlela yokushaja.

I-lithium isebenza kakhulu kuthebula le-periodic of element, njengokuminyanisa umzila ohamba ngaphansi komhlaba, wonke umuntu uyavinjwa emnyango, lapho ukuminya kuyanda, inkinga iyavinjwa. Wonke umuntu wabona izithombe eziningi ku-inthanethi, baxoshwa lapho beshaja.
