Uyini umehluko phakathi kwebhethri elijulile lomjikelezo nebhethri elijwayelekile?

Amabhethri wokugcina amandla adlala indima ebalulekile ekukhuliseni amandla amadivayisi ahlukahlukene nezinhlelo. Vele, kukhona amabhethri anokusebenza okuhlukile nokucaciswa. Kulolu bhulogi, sizokungenisa umehluko omkhulu phakathi kwebhethri elijulile lomjikelezo namabhethri ajwayelekile ukusiza abasebenzisi nabathengi ukuthi banqume lapho bekhetha ibhethri elifanela izidingo zabo.

Ibhethri elijulile lomjikelezo: yakhelwe ukukhishwa isikhathi eside, ukuphuma kancane

Amabhethri ajulile ajikeleze aklanyelwe izinhlelo zokusebenza ezinde nezisheshayo zokukhishwa, ngokungafani namabhethri ajwayelekile asetshenziselwa ukuqala izinjini noma ahlinzeke ama-burns amafushane amandla. Zizokwengeza ukumelana nenkokhiso ephindaphindekayo futhi zikhiphe imijikelezo ngaphandle kokuwohloka kokusebenza okubalulekile, okwenza balungele izinhlelo zokugcina amandla ezivuselelekayo, ama-RV, ama-Golf Carts, kanye nokufakwa kwe-off-grid. Ngokungafani namabhethri angenamjikelezo ajulile, abeka phambili ukuqhuma kwamandla aphezulu, amabhethri ajulile agcizelela ukulethwa kwamandla okuzinzile ngaphezulu kwezikhathi ezengeziwe. Ngokuvamile banamapuleti amakhulu nezinto zokwakha ezisebenzayo, zibavumela ukuba zibekezelele ukukhishwa okujulile ngaphandle kokuthinta impilo yabo yenkonzo.

Ibhethri elijwayelekile: Kwenzelwe izidingo zesikhathi esifushane, eziphakeme

Amabhethri ajwayelekile ajwayelekile amabhethri e-lithium-ion anamandla amakhulu namandla okuqina kwamandla, okuvumela ama-compact, amadizayini angasindi ngenkathi ahambisa ukusebenza okuhlaba umxhwele. Lawa mabhethri asebenzisa amakhompiyutha e-lithium njengama-electrolytes nezinto zokwenziwa kwe-cathode, evumela ukunyakaza okusheshayo kwe-ion nokudluliswa kwamandla okusebenzayo ngesikhathi sokushaja kanye nemijikelezo yokukhipha. Amabhethri e-lead-acid ngolunye uhlobo lwebhethri olujwayelekile oluvame ukusetshenziswa ezinhlotsheni zesikhashana, eziphakeme kakhulu, ikakhulukazi ezindaweni zezimoto nezimboni. Amabhethri e-lead-acid anamakhono aphezulu aphezulu, abenze balungele ukuqala, ukukhanyisa nokulahla izicelo (ama-sli) ezimotweni, kanye nezinhlelo zokukhanyisa eziphuthumayo kanye nezinhlelo zokukhanyisa eziphuthumayo. Lawa mabhethri asebenzisa ukuhola dioxide njenge-electrode enhle. I-Sponge Lead yi-electrode engemihle, futhi i-sulfuric acid yi-electrolyte ekhipha amandla namacala ngokushesha.

I-Chemistry ehlukile kanye nokwakheka phakathi kwebhethri elijulile lomjikelezo namabhethri ajwayelekile

Ngokuhlelekile, amabhethri ajulile ajulile anokwakhiwa okumanzi okunamapuleti amakhulu kanye nabahlukanisi bokumelana namacala aphindaphindwayo kanye nemijikelezo yokuphuma. Lawa mabhodi anokuqukethwe okuphezulu okuphezulu futhi anganikeza amandla angaguquki futhi athembekile esikhathini eside. Ngokwengeziwe, amabhethri ajwayelekile angaba namapuleti amancanyana nezindlu ezingaphansi zenzelwe izimfuno eziphakeme zamandla aphezulu. Imvamisa, abakhiqizi baklama bona ngemijikelezo yokucishwa okungajulile, futhi ukukhishwa okujulile kungathinta ukusebenza noma impilo yenkonzo.

Ngaphezu kwalokho, ngokombono we-electrolyte yokwakheka kwama-electrolyte, amabhethri ajulile asebenza ngokuvamile asebenzisa izixazululo ze-liquid Electrolyte, njenge-sulfuric acid, ezingafeza ukunyakaza okusebenzayo kwe-ion kanye nokuphendula kwe-electrochemical ngaphakathi kwebhethri. Abasebenzisi bangaphinda baphinde bakhiphe le gesi le-electrolyte ukuze balondoloze ukusebenza kwebhethri okulungile. Amabhethri ajwayelekile nawo angasebenzisa ama-electrolyte ama-liquid, anezakhi ezahlukahlukene ezenzelwe izici ezithile zokusebenza. Amanye amabhethri ajwayelekile angaba nokwakhiwa okuvaliwe ngejeli noma amunculwe ingilazi (AGM) Electrolyte ukunciphisa izidingo zokulungisa futhi kwandise ukuphepha.

Ibhethri elijulile lomjikelezo linokuphila okuhlukile komjikelezo nokuqina kunamabhethri ajwayelekile

Kunokwehluka okukhulu empilweni yomjikelezo nokuqina phakathi komjikelezo ojulile namabhethri ajwayelekile ngenxa yokwehluka kokuhlanganiswa kwamakhemikhali, ukwakheka okuhlelekile, kanye namaphethini wokusebenzisa okulindelekile. Amabhethri ajulile ajikeleze aklanyelwe ukubekezelela amakhulu noma izinkulungwane zokushaja futhi akhiphe imijikelezo ngaphandle kokuwohloka okukhulu. Ukwakhiwa kwabo okukhulu, amapuleti amakhulu, kanye nefomula ye-electrolyte eyenziwe kahle ibavumele ukumelana nokukhishwa okujulile kanye nokuphindaphinda kabili ngaphandle kokuyekethisa ukusebenza noma isikhathi eside. Ngokuphambene nalokho, abakhiqizi bavame ukwandisa amabhethri ajwayelekile emijikelezo yokukhipha amandla aphansi, engakhawulela impilo yabo yomjikelezo uma kuqhathaniswa namabhethri ajulile omjikelezo.

Ukuqina kwamabhethri ajulile okujikeleza kubenza balungele izinhlelo zokusebenza ezifunwayo ezidinga amandla aqhubekayo futhi athembekile esikhathini eside. Ukwakhiwa kwabo okugoqwe, amapuleti amakhulu, futhi ukwakheka okukhethekile kwe-electrolyte kubenze balungele ama-off-grid, amandla avuselelekayo, kanye ne-RV izinhlelo lapho ukuthembeka okujulile nokubutheliswa kwesikhathi eside kubalulekile. Amabhethri ajwayelekile angaba yisihlobo esihlala isikhathi eside kumabhethri ajulile ajikeleza futhi athambekele ekulimaleni noma ukwehluleka ngaphambi kwesikhathi lapho ekhishwa ngokujulile noma ehamba ngebhayisikile. Amabhodi abo anokwakhiwa okuncane futhi angagxili kakhulu, anciphisa ukufaneleka kwawo ukuze afune izinhlelo ezidinga amandla aqhubekayo noma ukuhamba ngebhayisikile okujulile.

Ukushaja kanye nezidingo zokulungisa

Amabhethri ajulile ancy adinga ukulungiswa ngezikhathi ezithile, njengokuphindaphinda amazinga we-electrolyte noma alinganise ukushaja, ukuqinisekisa ukusebenza kahle nokuphila isikhathi eside. Kodwa-ke, amabhethri wesimanje ajulile ajulile avame ukufaka ama-design avaliwe kanye nokusebenza kwamahhala, anciphise isidingo sokulungiswa okujwayelekile, kanti amabhethri ajwayelekile ancike ekuklameni kwawo kanye nokwakheka kwawo ama-electrolyte. Amabhethri we-lead-acid agcwele amanzi angadinga ukugcwaliswa kwe-electrolyte ye-electrolyte, ngenkathi uvalwe amabhethri we-lead-acid (agm, i-gel) anikeze ukusebenza kwamahhala ngokoqobo ngaphandle kokubheka noma agcwalise i-electrolyte.

Khetha ngokuya ngezimo ezahlukahlukene

Ukukhetha phakathi kwamabhethri ajulile ajikeleza namabhethri ajwayelekile kuya ngezidingo zakho ezithile kanye nezimo zokusetshenziswa. Amabhethri ajulile ajikelezayo angaba yisinqumo esihle kunazo zonke uma udinga amandla athembekile wokusebenzisa okuqhubekayo, ukusetshenziswa kwesikhathi eside kuzinhlelo zokusebenza ezifana nezinhlelo zamandla avuselelekayo noma izimoto zikagesi. Ibhethri elijwayelekile lingafaneleka kakhulu uma udinga amandla asheshayo ukuqala injini yakho noma imithwalo ye-Power Comlent.
