Isizukulwane esisha samabhethri e-sodium-ion siyatholakala, futhi amaTrams angenele inkathi ye- "sodium amabhethri"?

November 25, 2022

Muva nje, Catl, Umkhiqizi webhethri wamandla amakhulu emhlabeni, wakhipha ibhethri elisha le-sodium-ion, elidonsele ukunakwa okubanzi embonini. Ngabe isizukulwane esisha samabhethri e-sodium-ion kusho ukuthi izimoto ezintsha zamandla zizongena enkathini ye- "sodium amabhethri"?
Kwingqungquthela yabezindaba eyi-10-Minute Online Ikakhulu, ubuningi bamandla weseli elilodwa bufinyelele ku-160Wh / KG kanye ne-Inovative Lithium-Sodium Mashup Battery Pack ye-Sodium-Sodium Mashup ivunyelwe emakethe yokugcina amandla, ukuze ibekelwe isimo semakethe ye-Energy. . new1

Izinzuzo zamabhethri e-sodium-ion

Mayelana nebhethri le-sodium-ion elikhishwe kulokhu, idatha enikezwe yi-ningde Times yile: Ubuningi bamandla beseli elilodwa buphakeme njengo-160Wh / kg; Amandla angafinyelela ngaphezu kwama-80% lapho akhokhiswa imizuzu engu-15 emazingeni okushisa asekamelweni; endaweni yokushisa ephansi ye--20 ° C, futhi inesilinganiso sokukhipha esingaphezu kwama-90%; Ukusebenza kahle kwesistimu kungafinyelela ngaphezu kwama-80%; Ukuqina okushisayo kudlula kude izidingo zokuphepha zeZinga Eliqinile Kazwelonke.

Embonini yebhethri yangaphambilini, ubuningi bamandla bebhethri bebhethri le-sodium-ion belingu-120 Whi / kg, obekuphansi kakhulu kune-180Wh / kg yamabhethri we-lithium iron phosphate kanye 240Wh / kg wamabhethri we-ternary. Namuhla, ubuningi bamandla obuningi be-catl-ion ibhethri eliphansi liphansi kancane kunebhethri lamanje le-lithium iron phosphate ukusebenza okuphansi nokushaja okusheshayo, ikakhulukazi ezigabeni zesicelo samandla ezifundeni ze-alpine. Ngasikhathi sinye, uCatl washo nokuthi ubuningi bamandla bebhethri eliyisizukulwane esilandelayo se-sodium-ion kulindeleke ukuthi lidlule ku-200Wh / kg.

Kulula ukuthola "i-sodium", ayinqabile ne-lithium "

Eqinisweni, amabhethri e-sodium-ion namabhethri e-lithium-ion azalwa ngasikhathi sinye, kodwa "isizinda sokukhula" ahlukile.

Njengoba bobabili i-sodium ne-lithium bangezinto zensimbi ye-alkali entweni yokuqala eyinhloko yeqembu, banezakhiwo ezifanayo zamakhemikhali. Amabhethri e-Sodium-ion asebenza ngokufanayo kumabhethri e-lithium-ion, ngakho-ke akunzima ukubabeka esikhundleni senqubo yokwenza. Kodwa-ke, uma kuqhathaniswa nama-lithium ion, ama-sodium ion akhudlwana ngosayizi futhi abe nezidingo eziqinile ngokuya ngokuqina kwesakhiwo nokusebenza okunamandla, okubuye kube yi-bottleneck ukuthi kunzima ukuhweba.

Kodwa-ke, amabhethri e-sodium-ion agcizelelwa kabusha ngalesi sikhathi, okuhlobene "nokutholakala kalula kwe-sodium" kanye "nobulukhuni ukuthola i-lithium". Izinsizakusebenza ze-lithium zomhlaba wonke zigxile kakhulu eNingizimu Melika nase-Oceania. Izwe lami line-5.93% yezinsizakusebenza zomhlaba jithium. Iningi lezimayini ze-lithium litholakala e-Qinghai-Tibet Plateau, okunzima okwami.
Uma kuqhathaniswa nezinsizakusebenza ze-lithium ezilambile, izindawo zokugcina ze-sodium ziningi kakhulu, futhi izinsiza ze-sodium zisatshalaliswa kahle futhi intengo iphansi kakhulu. Okuqukethwe komhlaba wonke kwe-sodium kungachazwa njengokungapheli, "nolwandle".

Kungashiwo ukuthi ukuthuthukiswa kwamabhethri e-sodium-ion akunakugwema kuphela izingqinamba ze- "Price" kanye nokunikezwa kwamabhethri amandla, kepha futhi zisebenza ngokugcwele njengezengezo kumabhethri e-lithium-ion.

Kusezinsukwini zokuqala ze-sodium-ion ibhethri yebhethri
Ukusuka endaweni yokubuka, amabhethri e-sodium-ion abiza kakhulu kunamabhethri e-lithium emkhakheni wokugcinwa kwamandla. Amabhethri e-Sodium-ion aphephile, amancane, alula futhi abiza kakhulu.

Amabhethri e-Sodium-Ion anezinzuzo eziningi kangaka, ingabe inkathi yezimoto zikagesi ze-sodium-ion eza? Impendulo ayilungile. Ngenxa yevolumu enkulu yama-sodium ion kune-lithium ion, amabhethri e-sodium-ion ane-density yamandla ephansi. Yize isizukulwane esisha samabhethri e-sodium-ion ekhishwe yi-catl ine-density yamandla eduze kwe-lithium iron phosphate, akukude namabhethri e-livem-ion wamanje. Emotweni njenge-compact njengemoto yabagibeli, kunzima ukuba nesikhala esengeziwe sebhethri.

Mhlawumbe, amabhethri e-sodium-ion azosetshenziswa kabanzi emikhakheni enjengeziteshi zamandla okugcina amandla ezingadingi ubukhulu bamandla aphezulu.

Kodwa-ke, ngokwezikhungo zezimboni, izindleko zamabhethri we-sodium-ion zizobe ziphansi kuphansi kwalezi zibhethri ze-lithium-ion ngemuva kwezimboni, kepha ukuqina kwamandla kuphansi, ngakho-ke ngeke babuyise ngokuphelele amabhethri e-lithium, kepha angeke athathe isikhundla ngokuphelele Cishe isetshenziswe ezimotweni zamandla amasha aphansi, amamakethe amakhulu asungulwe ngokuya ngezimoto ezinamasondo neziteshi zamandla okugcina amandla.

Izinqubomgomo ezinhle zokuthuthukiswa kwamabhethri we-sodium-ion akhombisa namathemba abanzi amabhethri e-sodium-ion eziteshini zamandla okugcina amandla. NgoJulayi 15, IKhomishani Yezokuthuthukiswa Kwezwe Nezokubuyiselwa Kwezimali kanye neNational Energy Administration ekhiphe imali ethi "Okukhombisa Ngokusheshisa Ukuthuthukiswa Kwesitoreji Esisha Sendla", okukhomba ukuthi: Ukugcinwa kwamandla okusha kungubuchwepheshe obubalulekile kanye nemishini eyisisekelo exhasa uhlelo lwamandla olusha , futhi izothuthukisa ikhabhoni eqopheke enkambu yamandla. Dlala indima enkulu kwinqubo yokungathathi hlangothi. Kuyadingeka ukusheshisa ukuboniswa okukhulu kobuchwepheshe obunjenge-flywheel energy esitoreji namabhethri e-sodium-ion.
