Esimeni samanje sezinhlelo zamandla, isitoreji samandla simi njengento esemqoka eqinisekisa ukuhlanganiswa okungenazihibe kwemithombo yamandla avuselelekayo kanye nokuqinisa ukuqina kwegridi.Isebenzisa isikhathi sokukhiqiza amandla, ukuphathwa kwegridi, kanye nokusetshenziswa komsebenzisi wokugcina, okukunikeza ubuchwepheshe obubalulekile.Lesi sihloko sihlose ukuhlola nokuhlolisisa ukuwohloka kwezindleko, isimo samanje sokuthuthuka, namathemba esikhathi esizayo wezinhlelo zokugcina amandla ebhethri ye-lithium-ion.
Ukwehlukaniswa Kwezindleko Kwezinhlelo Zokugcina Amandla:
Isakhiwo sezindleko zezinhlelo zokugcina amandla ikakhulukazi sihlanganisa izingxenye ezinhlanu: amamojula ebhethri, Amasistimu Okulawula Ibhethri (BMS), iziqukathi (ezihlanganisa Amasistimu Okuguqula Amandla), izindleko zokwakha nezokufaka, nezinye izindleko zokuklama nokulungisa iphutha.Ngokuthatha isibonelo sesistimu yokugcina amandla engu-3MW/6.88MWh efektri eseSifundazweni saseZhejiang, amamojula ebhethri enza u-55% wesamba sezindleko.
Ukuhlaziywa Okuqhathaniswayo Kwezobuchwepheshe Bebhethri:
I-lithium-ion energy storage ecosystem ihlanganisa abahlinzeki bemishini ekhuphukayo, izihlanganisi ezimaphakathi, kanye nabasebenzisi bokugcina abazansi nomfula.Izisetshenziswa zisukela kumabhethri, Izinhlelo Zokulawula Amandla (EMS), Amasistimu Okulawula Ibhethri (BMS), kuya Ezinhlelweni Zokuguqula Amandla (PCS).Izihlanganisi zihlanganisa izihlanganisi zesistimu yokugcina amandla kanye nezinkampani zobunjiniyela, zokuthengwa kwempahla, nezokwakha (EPC).Abasebenzisi bokugcina bahlanganisa ukukhiqizwa kwamandla, ukuphathwa kwegridi, ukusetshenziswa komsebenzisi wokugcina, kanye nezikhungo zokuxhumana/zedatha.
Ukwakhiwa Kwezindleko Zebhethri Lithium-ion:
Amabhethri e-lithium-ion asebenza njengezingxenye eziyisisekelo zezinhlelo zokugcina amandla e-electrochemical.Njengamanje, imakethe ihlinzeka ngobuchwepheshe bebhethri obuhlukahlukene obufana ne-lithium-ion, i-lead-carbon, amabhethri okugeleza, namabhethri e-sodium-ion, ngalinye linezikhathi zokuphendula ezihlukile, ukusebenza kahle kokukhipha, kanye nezinzuzo ezihambisanayo nezithiyo.
Izindleko zephekhi yebhethri zenza ingxenye enkulu yezindleko zesistimu yokugcina amandla e-electrochemical, ehlanganisa kufika ku-67%.Izindleko ezengeziwe zihlanganisa ama-inverter esitoreji samandla (10%), amasistimu okuphatha ibhethri (9%), kanye nezinhlelo zokuphatha amandla (2%).Ngaphakathi kwezindleko zebhethri ye-lithium-ion, impahla ye-cathode ifuna ingxenye enkulu kunazo zonke cishe ku-40%, ilandelwa yi-anode material (19%), i-electrolyte (11%), nesihlukanisi (8%).
Amathrendi nezinselele zamanje:
Izindleko zamabhethri okugcina amandla zibone indlela eyehlayo ngenxa yokwehla kwezintengo ze-lithium carbonate kusukela ngo-2023. Ukwamukelwa kwamabhethri e-lithium iron phosphate emakethe yasekhaya yokugcina amandla kuqhubekisele phambili ukwehla kwezindleko.Izinto ezihlukahlukene ezifana ne-cathode ne-anode materials, isihlukanisi, i-electrolyte, umqoqi wamanje, izingxenye zesakhiwo, nezinye zibone ukulungiswa kwentengo ngenxa yalezi zici.
Noma kunjalo, imakethe yebhethri egcina amandla ishintshile isuka ekushodelweni kwamandla yaya esimweni sokuhlinzeka ngamandla, okuqinisa ukuncintisana.Abangenele abavela emikhakheni eyahlukene, okuhlanganisa abakhiqizi bamandla kagesi, izinkampani ze-photovoltaic, amafemu amabhethri okugcina amandla asafufusa, nomakadebona basembonini asebekhulile, bangenele umbango.Lokhu kuthutheleka, kuhambisana nokwandiswa kwamandla abadlali okukhona, kubeka engcupheni yokuhlelwa kabusha kwemakethe.
Isiphetho:
Naphezu kwezinselelo ezikhona zokugcwala ngokweqile kanye nokuncintisana okuphakeme, imakethe yokugcina amandla iyaqhubeka nokwanda kwayo ngokushesha.Njengoba ibhekwa njengesizinda esingaba ngamadola ayizigidigidi, yethula amathuba okukhula amakhulu, ikakhulukazi phakathi kokuphikelela kokukhuthazwa kwezinqubomgomo zamandla avuselelekayo kanye nezimboni ezikhuthele zaseShayina nezihweba.Kodwa-ke, kulesi sigaba sokuncintisana okuthe xaxa kanye nokuncintisana kwe-cutthroat, amakhasimende angezansi azofuna amazinga aphezulu ekhwalithi yamabhethri okugcina amandla.Abangenele abasha kumele bakhe imigoqo yezobuchwepheshe futhi bahlakulele amakhono asemqoka ukuze bachume kulo mhlaba oguquguqukayo.
Sekukonke, imakethe yaseShayina yamabhethri e-lithium-ion namandla okugcina amandla iveza inqwaba yezinselelo namathuba.Ukuqonda ukuwohloka kwezindleko, izitayela zobuchwepheshe, kanye nokuguquguquka kwemakethe kubalulekile emabhizinisini azama ukuklama ubukhona obusabekayo kulo mkhakha othuthukayo ngokushesha.
