Kweibhethri ye-lithiumesiteji sesicelo esikhulu, ukuthuthukiswa kwemboni yesitoreji samandla ebhethri ye-lithium nakho kusekelwa kakhulu ohulumeni. Izinzuzo ezisobala ezengeziwe zamabhethri e-lithium iron phosphate yokugcina amandla zaqala ukuya emphakathini. Umthamo ophelele wemakethe yokugcina amandla ebhethri ye-lithium mkhulu kakhulu, uhlangothi lwabasebenzisi lunamandla amakhulu.
Isimo sokugcina amandla ebhethri ye-lithium
I-China njenge-powerhouse entsha yamandla, imboni entsha yamandla eminyakeni yamuva ibilokhu intuthuko esheshayo yensimu yokugcina amandla nayo ibhekwe eduze, lapho ibhekene nesidingo esikhulu semakethe namandla, amabhizinisi okugcina amandla ebhethri e-lithium asekhaya afana ibhubesi elilele lilungele ukuhamba.
Isamba somthamo weibhethri ye-lithiumImakethe yokugcina amandla ikhulu kakhulu, uhlangothi lwabasebenzisi lwamandla amakhulu.
Ukusetshenziswa kwamanje kwesitoreji samandla ebhethri ye-lithium kubonakala kuyizindawo ezintathu ezinkulu zokugcina amandla: isitoreji samandla omoya esikhulu, amandla okulondoloza isisekelo sesiteshi sokuxhumana, isitoreji samandla somndeni. Phakathi kwazo, isizinda samandla esisekela isisekelo sokuxhumana sesiteshi samandla esisekela isizinda samandla njengamanje sinengxenye enkulu yokugcina amandla omndeni nguTesla asuse igagasi elithi "energy family", kunesikhala esikhulu sokuthuthuka nokunwetshwa, indawo enkulu yokugcina amandla omoya okwesikhashana. umfutho awubonakali ukhona.
Ubuchwepheshe bokugcina amandla ebhethri ye-Li-ion busondela ekuvuthweni kanye nokwehliswa kwezindleko kukonke
Sekukonke, eminyakeni yamuva, njengoba isidingo semakethe samabhethri e-lithium siqhubeka nokwanda, ukukhiqizwa kwenqwaba yamabhethri e-lithium, izindleko zayo ziyancipha unyaka nonyaka, intengo yamanje yanele ukuthuthukiswa kwezohwebo futhi isetshenziswe kabanzi. Ngaphezu kwalokho, amandla ebhethri e-lithium attenuation abe ngaphansi kuka-80% womthamo wokuqala, angasetshenziswa emkhakheni wokugcinwa kwamandla, kuqhubeke nokunciphisa izindleko zamabhethri e-lithium zokugcina amandla.
Njengamanje, ubuchwepheshe bokugcina amandla ebhethri ye-lithium busesesigabeni sokuthuthuka okuqhubekayo, igebe lobuchwepheshe phakathi kwasekhaya nakwamanye amazwe kukhona indawo yokuncipha, ibhethri ye-lithium yensimbi ye-phosphate kuya kumabhethri e-ternary lithium, bese kuya ezintweni zamanje ezishisayo ze-lithium titanate, kwezobuchwepheshe. ushintsho njalo kuthinta izindlekoamabhethri e-lithiumkanye nebhalansi yochungechunge lwezimboni, ngakho-ke abatshalizimali kufanele babhekane nengozi yokuthuthukiswa kwezobuchwepheshe kanye nokuthuthukiswa kwesimanje kokukhiqizwa kokufakwayo kwevolumu ephezulu.
Izinzuzo zamabhethri e-lithium endaweni yokugcina amandla
Iqhutshwa yizidingo eziqinile zokuthuthukiswa komphakathi kanye nemakethe enkulu engaba khona,iphakethe lebhethri le-lithiumubuchwepheshe bokugcina amandla buthuthuka ngendlela enkulu, ukusebenza kahle okuphezulu, impilo ende, izindleko eziphansi futhi akukho kungcola. Isitoreji samandla ebhethri ye-lithium njengamanje siyindlela yobuchwepheshe engenzeka kakhulu.
1. Ibhethri ye-lithium iron phosphate inomthamo omkhulu wamandla, ububanzi obuqinile, futhi ngokusetshenziswa kwezinto ze-lithium iron phosphate anode, impilo yebhethri ye-carbon anode lithium-ion yendabuko kanye nokuphepha kuye kwathuthukiswa kakhulu, ukusetshenziswa okuthandwayo emkhakheni wamandla. isitoreji.
2. Ukuphila komjikelezo omude wamabhethri e-lithium, esikhathini esizayo ukuthuthukisa ukuminyana kwamandla kuphansi kakhulu, ububanzi bubuthakathaka, intengo ephezulu yalezi ziphutha zenza ukusetshenziswa kwamabhethri e-lithium emkhakheni wokugcinwa kwamandla kungenzeka.
3. Ukusebenza kokuphindaphinda kwebhethri ye-lithium kuhle, ukulungiswa kulula, esikhathini esizayo ukuthuthukisa ukusebenza kwezinga lokushisa eliphezulu kanye nokusebenza kabi kokugibela ibhayisikili nokunye ukushiyeka kulungele ukusetshenziswa kwensimu yokugcina amandla.
4. Isistimu yomhlaba wonke yokugcina amandla ebhethri ye-lithium kubuchwepheshe kunolunye uhlelo lokugcina amandla ebhethri olubalwa kakhulu kunengxenye yamabhethri e-lithium-ion azoba inkambiso yesitoreji samandla esizayo. Ngo-2020, imakethe yamabhethri okugcina amandla izofinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingama-70.
5. Hlanza futhi akungcolisi. Amabhethri e-lithium awaqukethe i-lead, i-cadmium, i-mercury nezinye izinto ezinobuthi, futhi ngesikhathi esifanayo, ngoba ibhethri kufanele livalwe kahle, ngesikhathi sokusebenzisa amagesi ambalwa kakhulu akhishwe, akubangeli ukungcoliswa kwemvelo.
Indima eyinhloko yobuchwepheshe bokugcinwa kwamandla kagesi ohlelweni lwamandla ithola ukunakwa okwengeziwe ngokuthuthukiswa kokuguqulwa kwesistimu yamandla nokwakhiwa kwegridi ehlakaniphile. Kungakhathaliseki ukuthi ngokombono wemakethe yasekhaya noma yamazwe ngamazwe, amathemba emakethe yokugcina amandla e-lithium abanzi kakhulu. Ngokusekelwe ezinzuzweni zamabhethri e-lithium emkhakheni wezicelo zokugcina amandla, futhi angaqedwa ngamandla weamabhethri e-lithiumukuthola "indawo yokusebenzisa" entsha, izinkampani ezinkulu zaqala ukuhlela imakethe yokugcina amandla.
