Isifundo sokuthelekisa: I-Nickel-Metal Hydride (NiMH) vs. I-18650 ye-Lithium-Ion (i-Li-ion) Iibhetri - Ukuvavanya i-Pros and Cons

Intshayelelo:
Kwindawo yobuchwepheshe bebhetri ehlaziywayo, i-Nickel-Metal Hydride (NiMH) kunye ne-18650 ye-Lithium-Ion (i-Li-ion) iibhetri zimi njengeenketho ezimbini ezibalaseleyo, nganye inika iingenelo ezikhethekileyo kunye nezithintelo ngokusekelwe kwimichiza kunye noyilo lwazo. Eli nqaku lijolise ekunikeni uthelekiso olubanzi phakathi kwezi ntlobo zimbini zebhetri, ukuhlola ukusebenza kwazo, ukuqina, ukhuseleko, impembelelo yokusingqongileyo, kunye nezicelo zokunceda abasebenzisi ekwenzeni izigqibo ezinolwazi.

**Ukusebenza kunye noXinano lwaMandla:**
**Iibhetri zeNiMH:**
**Iizinto eziluncedo:** Ngokwembali, iibhetri ze-NiMH zibonelele ngomthamo ophezulu kuneendlela zangaphambili zokutshajwa kwakhona, ezibenza ukuba basebenzise izixhobo zombane ixesha elide. Babonisa amaxabiso aphantsi okuzikhupha xa kuthelekiswa neebhetri ezindala ze-NiCd, zibenza bafanelekele usetyenziso apho ibhetri ingasetyenziswa ixesha elithile.
**Iingxaki:** Nangona kunjalo, iibhetri ze-NiMH zinoxinano lwamandla olusezantsi kuneebhetri ze-Li-ion, okuthetha ukuba zininzi kwaye zinzima ngakumbi kwimveliso yamandla efanayo. Baphinde babone ukuhla kwe-voltage ebonakalayo ngexesha lokukhutshwa, okunokuchaphazela ukusebenza kwezixhobo eziphezulu zokukhupha.

**18650 iibhetri zeLi-ion:**
**Iizinto eziluncedo:** Ibhetri ye-18650 ye-Li-ion iqhayisa ngokuxinana kwamandla okuphezulu kakhulu, ukuguqulela kwinto encinci kunye nekhaphukhaphu kumandla alinganayo. Bagcina i-voltage engaguqukiyo ngakumbi kumjikelo wabo wokukhupha, beqinisekisa ukusebenza ngokugqibeleleyo de baphantse baphela.
  
**Ii-Cons:** Nangona zinika uxinano lwamandla oluphezulu, iibhetri ze-Li-ion zithandwa kakhulu ekuzikhupheni ngokukhawuleza xa zingasetyenziswa, zifuna ukutshaja rhoqo ukugcina ukulungela.

**Ukuqina kunye noBomi boMjikelo:**
**Iibhetri zeNiMH:**
**Iizinto eziluncedo:** Ezi bhetri zinokumelana nenani elikhulu lemijikelo yokukhutshwa kwentlawulo ngaphandle kokuthotywa okubalulekileyo, ngamanye amaxesha ukufikelela kuma-500 imijikelo okanye ngaphezulu, kuxhomekeke kwiipatheni zokusetyenziswa.
** Cons:** Iibhetri ze-NiMH zinengxaki yememori, apho ukutshaja okungaphelelanga kunokukhokelela ekuncitshisweni komthamo omkhulu ukuba kwenziwa ngokuphindaphindiweyo.

**18650 iibhetri zeLi-ion:**
-** IiPros:** Ubuchwephesha beLi-ion obukwinqanaba eliphezulu buwunciphise umba wempembelelo yememori, evumela iipateni zokutshaja eziguquguqukayo ngaphandle kokunciphisa umthamo.
**Iingxaki:** Ngaphandle kwenkqubela phambili, iibhetri ze-Li-ion zikholisa ukuba nenani eliqingqiweyo lemijikelo (malunga nama-300 ukuya kuma-500 imijikelo), emva koko umthamo wazo wehla ngokuphawulekayo.
**Ukhuseleko neMpembelelo yokusiNgqongileyo:**
**Iibhetri zeNiMH:**
**Iizinto eziluncedo:** Iibhetri ze-NiMH zibonwa zikhuselekile ngenxa yekhemistri eguquguqukayo, ebonisa umlilo ophantsi kunye nomngcipheko wokudubula xa kuthelekiswa ne-Li-ion.
**Iingxaki:** Ziqulethe i-nickel kunye nezinye iintsimbi ezinzima, ezifuna ukulahlwa ngononophelo kunye nokuhlaziywa kwakhona ukuthintela ukungcoliseka kwendalo.

**18650 iibhetri zeLi-ion:**
**Iizinto eziluncedo:** Iibhetri zale mihla ze-Li-ion zixhotyiswe ngeendlela zokhuseleko ezintsonkothileyo zokunciphisa imingcipheko, efana nokhuseleko lwe-thermal.
**I-Cons:** Ubukho bee-electrolyte ezinokutsha kwiibhetri ze-Li-ion kuphakamisa iinkxalabo zokhuseleko, ngakumbi kwiimeko zomonakalo womzimba okanye ukusetyenziswa kakubi.
 
**Iizicelo:**
Iibhetri ze-NiMH zifumana ukuthandwa kwizicelo apho umthamo ophezulu kunye nokhuseleko zibekwe phambili phezu kobunzima kunye nobukhulu, njengezibane zegadi ezisebenza ngelanga, izixhobo zasekhaya ezingenazintambo, kunye nezinye iimoto ezixutywe. Ngeli xesha, iibhetri ze-18650 ze-Li-ion zilawula kwizixhobo zokusebenza okuphezulu njengeelaptops, ii-smartphones, izithuthi zombane, kunye nezixhobo zombane ezikwinqanaba lobuchwephesha ngenxa yokuxinana kwamandla aphezulu kunye nokuphuma kwamandla ombane ozinzile.
 
Isiphelo:
Ekugqibeleni, ukhetho phakathi kwe-NiMH kunye neebhetri ze-18650 ze-Li-ion zixhomekeke kwiimfuno ezithile zesicelo. Iibhetri ze-NiMH zigqwesa ukhuseleko, ukuqina, kunye nokufaneleka kwezixhobo ezingabalulekanga kangako, ngelixa iibhetri ze-Li-ion zibonelela ngoxinano lwamandla olungenakuthelekiswa nanto, ukusebenza, kunye nokuguquguquka kwezicelo ezisebenza ngamandla. Ukuqwalasela iimeko ezifana neemfuno zokusebenza, uqwalaselo lokhuseleko, impembelelo yokusingqongileyo, kunye neemfuno zokulahlwa kubalulekile ekumiseleni obona buchwepheshe bufanelekileyo bebhetri kuyo nayiphi na imeko yokusetyenziswa.
