Kunezinzuzo nezingozi ezihlobene ne-chemistry yebhethri emibili eyinhloko esetshenziswa kumaphrojekthi okugcina amandla elanga + isitoreji. Amabhethri e-lead-acid asekhona isikhathi eside kakhulu futhi aqondakala kalula kodwa anemikhawulo kumthamo wawo wokugcina.Ibhethri le-lithium-ionZiphila isikhathi eside ngemijikelezo futhi zilula ngesisindo kodwa zibiza kakhulu ngokwemvelo.

Ukufakwa kwesitoreji ngokuvamile kuqukethe uhlobo olulodwa lwebhethri, njengakwi-LG Chem, lapha. Isithombe sivela ku-GreenBrilliance

Ingabe umuntu angahlanganisa izinzuzo zekhemistri ngayinye ukuze enze ibhange lebhethri elilodwa elingabizi kakhulu nelinamandla aphezulu?

Ingabe kuzodingeka umuntu ahlukanise ibhange lakhe lebhethri le-lead-acid ukuze nje asebenzise imisebenzi yebhethri elisha le-lithium-ion? Ingabe umuntu angangeza amabhethri e-lead-acid ashibhile ohlelweni lwakhe lwe-lithium ukuze ahlangabezane nomthamo othile we-kilowatt-hora?

Yonke imibuzo ebalulekile enempendulo engachazwanga kahle: kuya ngokuthi kuncike kuphi. Kulula futhi akunangozi kangako ukunamathela kumakhemikhali owodwa, kodwa kukhona okunye okufanele kwenziwe.

UGordon Gunn, unjiniyela kagesi eFreedom Solar Power eTexas, uthe kungenzeka ukuxhumanisa amabhethri e-lead-acid kanye ne-lithium ndawonye, ​​kodwa kuphela ngokuxhumanisa i-AC.

“Awukwazi nhlobo ukuxhuma amabhethri e-lead-acid kanye ne-lithium ebhasini elifanayo le-DC,” esho. “Okuhle kakhulu, kungabhubhisa amabhethri, futhi okubi kakhulu…umlilo? Ukuqhuma? Ukufundwa kwe-space-time continuum? Angazi.”

U-K. Fred Wehmeyer, iPhini likaMongameli Omkhulu Wobunjiniyela enkampanini yamabhethri e-lead-acid e-US Battery Manufacturing Co., unikeze incazelo eyengeziwe.

“Ingenziwa, kodwa bekungeke kube lula njengokumane ungeze amabhethri e-lead-acid ohlelweni lwebhethri le-lithium. Lezi zinhlelo ezimbili empeleni bezizosebenza ngokuzimela,” kusho uWehmeyer. “Uhlelo lwebhethri le-lithium belusazodingeka lulawulwe yi-BMS yalo eneshaja yalo kanye nesilawuli sokushaja. Uhlelo lwebhethri le-lead-acid beluzodinga ishaja yalo kanye/noma isilawuli sokushaja kodwa belungeke ludinge i-BMS. Lezi zinhlelo ezimbili zingase zihlinzeke ngemithwalo efanayo ngesikhathi esifanayo kodwa kungadingeka kube nokulawula okuthile ukuze kwabelwe ngokuphephile ukusatshalaliswa komthwalo phakathi kwamakhemikhali amabili.”

UTroy Daniels, umphathi wezinsizakalo zobuchwepheshe womkhiqizi wamabhethri e-LFP i-SimpliPhi Power, akakukhuthazi ukuxuba ikhemikhali efanayo yebhethri ingasaphathwa eyokuhlukahluka kwekhemikhali ohlelweni olulodwa, kodwa uyavuma ukuthi kungenziwa.

“Izindlela ezimbalwa zokuhlanganisa kungaba yindlela yokuba nezinhlelo ezimbili ezihlukene (zombili ishaja kanye ne-inverter) ezingabelana ngomthwalo ofanayo noma zihlukanise imithwalo kagesi edingekayo.” “Kungasetshenziswa neswishi yokudlulisa; nokho, lokhu kungasho ukuthi isethi eyodwa kuphela yamabhethri noma ikhemistri engashaja noma ikhiphe ngesikhathi futhi cishe kuzodingeka kube ukudluliselwa ngesandla.”

Ukuhlukanisa imithwalo nokusetha izinhlelo ezimbili ngokuvamile kuwumsebenzi oyinkimbinkimbi kakhulu kunalokho abaningi abafuna ukukwenza.

“Asikaze sibhekane nohlelo lwe-lithium/lead-acid oluhlanganisiwe kwaFreedom Solar ngoba bekungeke kube yinto eshibhile yokwengeza, futhi sizama ukugcina ukufakwa kwebhethri lethu kulula ngokusebenzisa ikhemikhali yebhethri elilodwa kuphela kanye nomkhiqizo webhethri elilodwa,” kusho uJosh Meade, umphathi we-PE kanye nomklamo.

Kukhona inkampani eyodwa ezama ukwenza ukuhlanganisa la makhemikhali amabili kube lula kancane. Umkhiqizi womkhiqizo wamandla aphathekayo i-Goal Zero ine-Yeti Portable Power Station esekelwe ku-lithium engasetshenziswa ekusekeleni ikhaya okuyingxenye. I-Yeti 3000 iyibhethri le-lithium le-3-kWh, 70-lb NMC elingasekela amasekethe amane. Uma kudingeka amandla engeziwe, i-Goal Zero inikeza i-Yeti Link Expansion Module yayo evumela ukwengezwa kwamabhethri okukhulisa i-lead-acid. Yebo, kunjalo: Ibhethri le-lithium Yeti lingabhangqwa ne-lead-acid.

“Ithangi lethu lokunweba liyibhathini eliyimfihlakalo, eliyi-lead-acid. Lokhu kukuvumela ukuthi usebenzise izinto zikagesi eziku-Yeti [uhlelo olusekelwe ku-lithium] kodwa kwandise ibhethri,” kusho uBill Harmon, i-GM ku-Goal Zero. “Ku-1.25-kWh ngayinye, ungangeza [amabhethri e-lead-acid] amaningi ngangokunokwenzeka. Ikhasimende lingawaxhuma nje. Ngokungazelelwe uthola ukuphatheka kwebhethri le-lithium kanye namabhethri e-lead-acid ashibhile ahlala ekhaya.”

Izinkinga ezinkulu lapho uzama ukuxhumanisa i-lithium ne-lead-acid ndawonye ama-voltage awo ahlukene, amaphrofayili okushaja kanye nemikhawulo yokushaja/yokukhipha. Uma amabhethri engekho ku-voltage efanayo noma ekhipha ngesivinini esingalingani, amandla azosebenza ngokushesha phakathi kwawo. Lapho amandla esebenza ngokushesha, kuvela izinkinga zokushisa futhi kuphazamise ukusebenza kahle komjikelezo webhethri.

I-Goal Zero ilawula lesi simo ngedivayisi yayo ye-Yeti Link. I-Yeti Link empeleni uhlelo lokuphatha ibhethri oluyinkimbinkimbi olufanele ibhethri lokuqala le-Yeti lithium elilawula ama-voltage kanye nokushaja phakathi kwamakhemikhali ahlukene.

“I-Yeti Link ilawula ukudluliselwa kwamandla phakathi kwamabhethri.” kusho uHarmon. “Sivikela ngendlela ephephile, ukuze ibhethri le-lithium lingazi nokuthi lihlanganiswe nebhethri le-lead-acid.”

I-Yeti 3000 ingaba ncane kunebhethri lasekhaya le-lithium elivamile – amamodeli e-LG Chem. I-Tesla nama-sonnets ngokuvamile anamandla okungenani angu-9.8 kWh – kodwa lokho kuyisibonelo sayo, kusho uHarmon. Futhi uma othile engayikhulisa ifike kulolo phawu lwe-9-kWh ngamabhethri e-lead ashibhile futhi aphathe nebhethri le-lithium lapho ekhempini noma ehamba ngemuva, kungani kungenjalo?

“Uhlelo lwethu lungolwabo bonke abantu ezweni abangenayo imali engu-$15,000 yokutshala imali ekufakweni kwesitoreji samandla. Bese kuthi uma sengiqedile, konke engikudingayo ukuba yinto efakwe unomphela ekhaya lami,” kusho uHarmon. “I-Yeti ilungele labo abasengozini yalokho abachitha imali kukho. Uhlelo lwethu luyi-$3,500 iyonke efakiwe.”

I-Goal Zero manje isisesizukulwaneni sayo sesihlanu somkhiqizo, ngakho-ke iqinisekile ngamakhono ayo okuhlanganisa i-lithium-lead. Kodwa kwabanye abaningi abangakhululekile ukuxuba i-chemistry yebhethri ngokuphelele, izinhlelo ezimbili ezizimele nezizimele zingafakwa ebhizinisini elifanayo noma ekhaya - inqobo nje uma zisethwe uchwepheshe kagesi.

“Indlela elula nephephile yokwengeza umthamo wokugcina oshibhile ohlelweni lwe-lithium olukhona kungaba ukuhlukanisa imithwalo bese uyibeka ngokwehlukana ezinhlelweni ezimbili zamabhethri.” kusho uWehmeyer wase-US Battery. “Noma ngabe yikuphi. Kufanele kwenziwe uchwepheshe oqeqeshiwe ukuze kugcinwe ukuphepha.”
