Njengenxalenye ephambili yezitulo ezinamavili zombane, uhlobo lwebhetri luchaphazela ngokuthe ngqo amava omsebenzisi kunye nokusebenza ngokubanzi. Okwangoku, iibhetri ze-lead-acid kunye ne-lithium-ion zilawula imarike, nganye ineempawu zayo ezizodwa, ezihambelana neemfuno ezahlukeneyo kunye nohlahlo-lwabiwo mali.

 

Iibhetri zeLead-Acid: Ukhetho olungabizi kakhulu noluqhelekileyo

Iibhetri ze-lead-acid zingumthombo wamandla wexesha elide kwizitulo ezinamavili zombane. Ii-electrode zazo zenziwe ikakhulu yi-lead kunye nee-oxides zayo, kwaye isisombululo se-sulfuric acid sisebenza njenge-electrolyte, sigcina kwaye sikhupha amandla ngokusebenzisa ii-chemical reactions. Iingenelo eziphambili zolu hlobo lwebhetri kukufikeleleka kwayo, okunceda ukulawula iindleko zizonke. Ubuchwepheshe bayo obuvuthiweyo kunye nokulula kokugcinwa kwayo kwenza ukuba ifaneleke kubasebenzisi abaqaphela uhlahlo lwabiwo-mali.

 

Nangona kunjalo, iibhetri ze-lead-acid zinzima, zongeza ubunzima besithuthi kwaye zenza kube nzima ukuzithutha. Uxinano lwazo lwamandla aphantsi ludla ngokunciphisa uluhlu lwazo. Ngaphezu koko, ezi bhetri zinobomi obufutshane bomjikelo, kwaye ukukhupha amanzi amdaka rhoqo kunye nemijikelo yokutshaja enzulu kukhawulezisa ukuwohloka komthamo. Ukuhlolwa rhoqo kwe-electrolyte kunye nokuphepha ukukhupha amanzi amdaka kakhulu kubalulekile.

 

Iibhetri ze-lead-acid zifanelekile ngokukodwa kubasebenzisi abaneentshukumo ezizinzileyo kwaye ababeka phambili iindleko zokuqala zotyalo-mali, ezifana nezo zisetyenziswa rhoqo ngaphakathi okanye kumakhaya abantu abadala. Ikwasebenza kakhulu kwiindawo eziveliswa ngobuninzi apho ubunzima bungabalulekanga kangako kwaye ukuthengwa kufuneka kulawulwe.

 

 

Iibhetri zeLithium: Isisombululo sanamhlanje sobomi bebhetri obukhaphukhaphu nobuhlala ixesha elide

Iibhetri zeLithium zisebenzisa i-lithium metal okanye ii-lithium compounds njengezinto ze-electrode, zixhomekeke ekudlulisweni kwee-ion ze-lithium phakathi kwee-electrode ezilungileyo nezingalunganga ukuze kugqitywe inkqubo yokutshaja nokukhupha. Zibonelela ngoxinano olukhulu lwamandla kwaye zinobunzima obungaphantsi kakhulu kuneebhetri ze-lead-acid ezinomthamo ofanayo, zinciphisa kakhulu ubunzima besithuthi kwaye ziphucula ukuthwaleka. Zikwabonelela ngoluhlu oluphezulu, kunye noqwalaselo oluqhelekileyo olunokudlula iikhilomitha ezingama-25.

 

Ezi bhetri zinobomi obude bomjikelo, azifuni ukutshintshwa okuninzi kulo lonke ixesha lazo lobomi, azidingi kugcinwa, azidingi nkxaso yokutshaja xa useluhambeni, kwaye azibonisi mpembelelo yememori. Nangona kunjalo, iibhetri ze-lithium zinexabiso eliphezulu lokuqala kunye neemfuno zoyilo oluqinileyo lwesekethe yokutshaja, ezifuna inkqubo ekhethekileyo yolawulo lwebhetri (BMS) yokulawula umbane okhuselekileyo kunye nobushushu.

 

Kubasebenzisi abanemisebenzi emininzi yemihla ngemihla, abahamba rhoqo, okanye abasebenzisa rhoqo izithuthi zikawonke-wonke, iibhetri ze-lithium zibonelela ngeenzuzo ezibalulekileyo ngokubhekiselele ekuthwaleni nasekusebenzeni kwebhetri. Zikwafaneleka ngakumbi kwabo bakhaphukhaphu okanye abafuna ukuthuthwa rhoqo.

 

 

Ungayikhetha njani ibhetri efanelekileyo?

Sicebisa ukuba uqwalasele imeko yakho yokwenyani yokusebenzisa, uhlahlo lwabiwo-mali, kunye neemfuno zobomi bebhetri:

Ukuba uhamba imigama emide rhoqo kwaye ubeka phambili ukuphatheka lula kunye nokusetyenziswa okulula, iibhetri ze-lithium zingcono.

Ukuba indlela oyisebenzisa ngayo ibanzi kwaye uhlahlo lwabiwo-mali lwakho lulinganiselwe, iibhetri ze-lead-acid zihlala zithembekile, ziluncedo, kwaye zingabizi kakhulu.
