Kukho izinto ezilungileyo kunye nezingalunganga ezinxulumene neekhemikhali ezimbini eziphambili zebhetri ezisetyenziswa kwiiprojekthi zesola + zokugcina.Iibhetri ze-lead-asidi zikhona ixesha elide kwaye ziqondakala lula kodwa zinemida kumthamo wazo wokugcina.Ibhetri yeLithium-ions banomjikelo omde wobomi kwaye bakhaphukhaphu ngobunzima kodwa ngokwendalo babiza kakhulu.

Ngaba umntu unokudibanisa i-pros yekhemistri nganye ukwenza ibhanki enye enexabiso eliphezulu, ibhetri ephezulu?

Ngaba umntu uya kufuneka achithe ibhanki yebhetri ye-lead-asidi ukuze angene kwimisebenzi yebhetri entsha ye-lithium-ion?Ngaba umntu unokongeza iibhetri ezineasidi ezinexabiso eliphantsi kwi-lithium yazo ukuhlangabezana nomthamo othile weyure yekilowatt?

Yonke imibuzo ebalulekileyo enempendulo engachazwanga: kuxhomekeke.Kulula kwaye kuncinci umngcipheko ukunamathela kwikhemistri enye, kodwa kukho umsebenzi ojikelezayo.

UGordon Gunn, injineli yombane kwiFreedom Solar Power eTexas, uthe mhlawumbi kunokwenzeka ukudibanisa i-lead-asidi kunye neebhetri ze-lithium kunye, kodwa kuphela ngokudibanisa kwe-AC.

“Awunakukwazi ukudibanisa iibhetri ze-lead-asidi kunye ne-lithium kwibhasi enye ye-DC,” utshilo.“Okona kulungileyo, bekuya kutshabalalisa iibhetri, kwaye okona kubi…kutsha?Ugqabhuko-dubulo?Ukufundwa kokuqhubeka kwexesha lesithuba?Andaz."

K. Fred Wehmeyer, i-VP ephezulu yobunjineli kwinkampani yebhetri ye-lead-acid yase-US Battery Manufacturing Co., inike ingcaciso eyongezelelweyo.

“Inokwenziwa, kodwa ibingayi kuba lula njengokongeza nje iibhetri ezineasidi ekhokelayo kwinkqubo yebhetri ye-lithium.Ezi nkqubo zimbini ziya kuba zisebenza ngokuzimeleyo, ”utshilo u-Wehmeyer.“Isistim yebhetri ye-lithium isafuneka ukuba ilawulwe yi-BMS yayo ngetshaja yayo kunye nesilawuli sentlawulo.Inkqubo yebhetri ye-lead-asidi iya kufuna itshaja kunye/okanye isilawuli sokutshaja kodwa ayifuni i-BMS.Ezi nkqubo zimbini zinokubonelela ngemithwalo elinganayo ngokunxuseneyo kodwa kunokufuneka kubekho ulawulo lokwaba ngokukhuselekileyo ukuhanjiswa komthwalo phakathi kweekhemistri zombini.

UTroy Daniels, umphathi weenkonzo zobugcisa we-LFP umenzi webhetri ye-SimpliPhi Power, ayicebisi ukuxuba i-chemistry yebhetri efanayo ivumela ukuba i-chemistry ihluke kwinkqubo enye, kodwa uyavuma ukuba inokwenziwa.

"Iindlela ezimbalwa zokudibanisa inokuba yindlela yokuba neenkqubo ezimbini ezizimeleyo (zombini itshaja kunye ne-inverter) ezinokwabelana ngomthwalo oqhelekileyo okanye nokwahlula imithwalo yombane efunekayo." uthe.“Utshintshiselwano lunokusetyenziswa;nangona kunjalo, oku kuya kuthetha ukuba iseti enye kuphela yeebhetri okanye ikhemistri enokuthi ihlawuliswe okanye ikhuphe ngexesha kwaye kuya kufuneka ukuba idluliselwe ngesandla.

Ukwahlula imithwalo kunye nokuseta iinkqubo ezimbini kudla ngokuba ngumsebenzi onzima ngakumbi kunokuba abaninzi bafuna ukungena.

“Asikhange sijongane ne-hybrid lithium/lead-acid system kwiFreedom Solar kuba ibingayi kuba sisongezo esincinci, kwaye sizama ukugcina ukufakwa kwebhetri yethu kulula ngokusebenzisa ikhemistri yebhetri enye kunye nemveliso yebhetri enye, ” utshilo uJosh Meade, PE kunye nomphathi woyilo.

Kukho inkampani enye ezama ukwenza ukudibanisa ikhemistri ezimbini kube lula.Umvelisi ophathwayo wemveliso yamandla Injongo Zero ine-lithium-based Yeti Portable Power Station engasetyenziselwa ukugcinwa kwekhaya ngokuyinxenye.I-Yeti 3000 yi-3-kWh, i-70-lb NMC ibhetri ye-lithium enokuxhasa iisekethe ezine.Ukuba kufuneka amandla amaninzi, i-Goal Zero inikezela i-Yeti Link Expansion Module evumela ukongezwa kweebhetri zokwandisa i-lead-acid.Ewe, kunjalo: Ibhetri ye-lithium Yeti inokudityaniswa ne-lead-asidi.

“Itanki yethu yokwandisa ngumjikelo ongaqondakaliyo, ibhetri eneasidi yelothe.Oku kukuvumela ukuba usebenzise i-electronics kwi-Yeti [i-lithium-based system] kodwa yandisa ibhetri, "utshilo uBill Harmon, GM kwi-Goal Zero.“Nge-1.25-kWh nganye, unokongeza [iibhetri ze-lead-asidi] ezininzi kangangoko ufuna.Umthengi unokuzifaka nje. Ngequbuliso ufumana ukuphatheka kwebhetri ye-lithium kunye neebhetri ze-asidi zelothe ezingabizi zihleli ekhaya.

Iingxaki ezinkulu xa uzama ukudibanisa i-lithium kunye ne-lead-asidi kunye ne-voltages yazo eyahlukileyo, iiprofayili zokutshaja kunye nemida yentlawulo / yokukhupha.Ukuba iibhetri ziphuma kwi-voltage efanayo okanye zikhupha kwimilinganiselo engafanelekanga, amandla aya kusebenza ngokukhawuleza phakathi komnye nomnye.Xa amandla ebaleka ngokukhawuleza, imiba yokufudumeza ivela kwaye iqaqambise ukusebenza kakuhle komjikelo webhetri.

Injongo yeZero ilawula le meko kunye nesixhobo sayo se-Yeti Link.I-Yeti Link yinkqubo yolawulo yebhetri ephucukileyo elungele ibhetri ye-Yeti lithium yoqobo elawula umbane kunye nokutshaja phakathi kwekhemistri eyahlukeneyo.

"I-Yeti Link ilawula ukuhanjiswa kwamandla phakathi kweebhetri.” watsho uHarmon."Sikhusela ngendlela ekhuselekileyo, ukuze ibhetri ye-lithium ingazi nokuba itshatile nebhetri ye-lead-asidi."

I-Yeti 3000 inokuba yincinci kuneebhetri zasekhaya ze-lithium - LG Chem.Iimodeli zeTesla kunye nee-sonnets zihlala zine-9.8 kWh yamandla-kodwa ngumzobo wayo, utshilo uHarmon.Kwaye ukuba umntu unokuyandisa ukuya kufikelela kulaa manqaku angama-9-kWh ngebhetri yelothe efikelelekayo kwaye aphinde ahambe nebhetri ye-lithium xa usenkampini okanye ucutha umva, kutheni kungenjalo?

“Inkqubo yethu yeyabo bonke abantu belizwe abangenayo i-15,000 yeedola ukuze batyale imali kwindawo yokugcina amandla.Kwaye ke xa ndigqibile, kufuneka ndibe yinto esisigxina ekhayeni lam,” utshilo uHarmon.“I-Yeti yeyabo basemngciphekweni wento abachitha imali kuyo.Inkqubo yethu yi-$3,500 iyonke efakiweyo.”

Injongo yeZero ngoku ikwisizukulwana sayo sesihlanu semveliso, ngoko iqinisekile kubuchule bayo bokudibanisa i-lithium-lead.Kodwa kwabanye abaninzi abangakhululekanga kangako ekuxubeni ikhemistri yebhetri ngokuthe ngqo, iinkqubo ezimbini ezizimeleyo nezizimeleyo zinokufakelwa kwishishini elinye okanye kwikhaya elinye – okoko nje imiselwe yingcali yombane.

“Indlela elula nekhuselekileyo yokongeza umthamo wogcino lwexabiso eliphantsi kwinkqubo ekhoyo ye-lithium iya kuba kukwahlulahlula imithwalo kwaye yabele ngokwahlukeneyo kwiinkqubo zebhetri ezimbini.” Utshilo uWehmeyer weBattery yase-US."Ngolunye uhlobo.Ifanele ukwenziwa yingcali eqeqeshiweyo ukugcina ukhuseleko.”
