Amabhethri e-lithium-ion akuwo wonke amagajethi onawo.Kusukela kuma-smartphone kuya ezimotweni zikagesi, lawa mabhethri aguqule umhlaba.Nokho, amabhethri e-lithium-ion anohlu olukhulu lwezinkinga ezenza i-lithium iron phosphate (LiFePO4) ibe ukukhetha okungcono.

Ahluke Kanjani Amabhethri e-LiFePO4?

Uma sikhuluma ngokuqinile, amabhethri e-LiFePO4 nawo angamabhethri e-lithium-ion.Kukhona ukuhlukahluka okuningana okuhlukene kumakhemikhali ebhethri ye-lithium, futhi amabhethri e-LiFePO4 asebenzisa i-lithium iron phosphate njengento ye-cathode (uhlangothi olubi) kanye ne-graphite carbon electrode njenge-anode (uhlangothi oluhle).

Amabhethri e-LiFePO4 anomthamo ophansi wamandla wezinhlobo zebhethri le-lithium-ion zamanje, ngakho awafiseleki kumadivayisi abamba isikhala njengama-smartphone.Kodwa-ke, lokhu kuhwebelana kokuqina kwamandla kuza nezinzuzo ezimbalwa ezinhle.

Izinzuzo LiFePO4 Amabhethri

Okunye okungalungile okuyinhloko kwamabhethri e-lithium-ion avamile ukuthi aqala ukuguga ngemva kwamakhulu ambalwa emijikelezo yokushaja.Yingakho ifoni yakho ilahlekelwa umthamo wayo omkhulu ngemva kweminyaka emibili noma emithathu.

Amabhethri e-LiFePO4 ngokuvamile ahlinzeka okungenani imijikelezo yokushaja egcwele engu-3000 ngaphambi kokuba aqale ukulahlekelwa amandla.Amabhethri ekhwalithi engcono asebenza ngaphansi kwezimo ezikahle angadlula imijikelezo engu-10,000.Lawa mabhethri futhi ashibhile kunamabhethri e-lithium-ion polymer, njengalawo atholakala kumafoni namalaptop.

Uma kuqhathaniswa nohlobo oluvamile lwebhethri ye-lithium, i-nickel manganese cobalt (NMC) lithium, amabhethri e-LiFePO4 anezindleko eziphansi kancane.Kuhlanganiswe nokuphila okungeziwe kwe-LiFePO4, ishibhile kakhulu kunezinye izindlela.

Ukwengeza, amabhethri e-LiFePO4 awanayo i-nickel noma i-cobalt kuwo.Zombili lezi zinsiza azivamile futhi ziyabiza, futhi kunezindaba zemvelo kanye nezimiso zokuziphatha ezizungeze ukumbiwa kwazo.Lokhu kwenza amabhethri e-LiFePO4 abe uhlobo lwebhethri oluluhlaza olunokungqubuzana okuncane okuhlotshaniswa nezinto zawo.

Inzuzo yokugcina enkulu yalawa mabhethri ukuphepha kwawo okuqhathaniswa namanye amakhemikhali ebhethri ye-lithium.Ngokungangabazeki ufunde mayelana nemililo yebhethri ye-lithium kumadivayisi afana nama-smartphone namabhodi ebhalansi.

Amabhethri e-LiFePO4 azinzile ngokwemvelo kunezinye izinhlobo zebhethri ye-lithium.Kunzima ukuvutha, ukuphatha kangcono amazinga okushisa aphezulu futhi awaboli njengamanye amakhemikhali e-lithium avame ukwenza.

Kungani Sibona Lawa Mabhethri Manje?

Umbono wamabhethri e-LiFePO4 washicilelwa okokuqala ngo-1996, kodwa kwaze kwaba ngu-2003 lapho lawa mabhethri aqala ukusebenza ngempela, ngenxa yokusetshenziswa kwama-carbon nanotubes.Kusukela lapho, kuthathe isikhathi ukuthi ukukhiqizwa ngobuningi kunyuke, izindleko zibe nokuncintisana, kanye nezimo ezingcono kakhulu zokusebenzisa lawa mabhethri ukuthi zicace.

Sekuphele iminyaka engu-2010 nasekuqaleni kwawo-2020 lapho imikhiqizo yezentengiso enobuchwepheshe be-LiFePO4 evelela isitholakala emashalofini nasezingosini ezifana ne-Amazon.

Nini Yokucabangela I-LiFePO4

Ngenxa yobuningi bawo obuphansi bamandla, amabhethri e-LiFePO4 awawona ukukhetha okuhle kubuchwepheshe obuphathekayo obuncane nobulula.Ngakho-ke ngeke uwabone kuma-smartphone, amathebulethi, noma amakhompyutha aphathekayo.Okungenani okwamanje.

Kodwa-ke, uma ukhuluma ngamadivayisi asikho isidingo sokuhamba nawe, lokho kuminyana okuphansi akubalulekile kangako.Uma ubheke ukuthenga i-UPS (Uninterruptible Power Supply) ukuze ugcine umzila wakho noma indawo yokusebenza ivuliwe ngesikhathi sokunqamuka kukagesi, i-LiFePO4 iyisinqumo esihle.

Eqinisweni, i-LiFePO4 isiqala ukuba yinketho ekhethwayo yezinhlelo zokusebenza lapho amabhethri e-lead acid afana nalawo esiwasebenzisa ezimotweni abe yisinqumo esingcono ngokwesiko.Lokho kufaka isitoreji samandla elanga sasekhaya noma izipele zamandla ahlanganiswe negridi.Amabhethri e-asidi yomthofu anzima kakhulu, anamandla amancane, anesikhathi sokuphila esifushane kakhulu, anobuthi, futhi awakwazi ukumelana nokukhishwa okujulile okuphindaphindiwe ngaphandle kokwehlisa isithunzi.

Uma uthenga amadivaysi asebenzisa amandla elanga njengokukhanya kwelanga, futhi unenketho yokusebenzisa i-LiFePO4, cishe njalo kuyisinqumo esifanele.Idivayisi ingase isebenze iminyaka ngaphandle kokudinga ukulungiswa.
