Ngokufutshane ukwazisa umahluko phakathi kwebhetri ye-Ni-MH etshajwayo kunye nebhetri ye-lithium
Xa kuthelekiswa neebhetri ze-nickel-hydrogen, sonke siyazi ukuba, umhleli olandelayo uya kukwazisa ngokufutshane iibhetri ze-nickel-hydrogen kunye neebhetri ze-lithium. Ukuba unomdla kwizihlangu zabantwana, jonga ~~~ Ukuqonda kwakho okunzulu kwezi bhetri zimbini kuya kuba luncedo kakhulu kuwe. Uncedo~~~
Kuzisa
Iibhetri zeNiMH
Ibhetri ye-Ni-MH yenziwe nge-hydrogen ion kunye ne-metallic nickel. Uvimba wayo wamandla ngama-30% ngaphezulu kwebhetri yenickel-cadmium. Ikhaphukhaphu kuneebhetri ze-nickel-cadmium, inobomi obude benkonzo, inongcoliseko olukhulu lokusingqongileyo, kwaye ayinasiphumo sokukhumbula. Ukungalungi kweebhetri ze-nickel metal hydride kukuba iibhetri ze-nickel cadmium zibiza kakhulu kuneebhetri ze-lithium.
ibhethri ibhetri
Ibhetri yeLithium yibhetri eyaqanjwa nguThomas Edison. Isebenzisa isinyithi se-lithium okanye i-lithium alloy njengento efanelekileyo ye-electrode kwaye isebenzisa isisombululo esingenamanzi se-electrolyte. I-equation yokusebenza kwebhetri yiLi+MnO2=LiMnO2. I-reaction yahlulwe ibe yi-oxidation-reduction reaction kunye ne-dicharge reaction. Kwixesha elidlulileyo, iibhetri ze-lithium azizange zisetyenziswe ngokubanzi ngenxa yeempawu zabo zeekhemikhali ezikhethekileyo, iimfuno eziphezulu zokucubungula, ukugcinwa kunye nokusetyenziswa, kunye neemfuno eziphezulu zokusingqongileyo. Ngophuhliso lwesayensi yanamhlanje, iibhetri ze-lithium ziye zaba yinto eqhelekileyo.
Ivolumu
Xa kuthelekiswa neebhetri eziqhelekileyo ze-nickel-cadmium/nickel-metal hydride, iibhetri ze-lithium ezitshajwayo zineenzuzo zobukhulu obuncinci (ngokomlinganiselo), ubunzima obulula, isantya esiphantsi sokuzikhupha, akukho siphumo sokukhumbula, njl., kwaye sele isetyenziswa ngokubanzi kwizinto ezininzi ezintsha izixhobo eziphathwayo. Iibhetri zeLithium ziye zatshintsha ngokuthe ngcembe iibhetri kwizixhobo eziphathwayo ezinjengeefowuni eziphathwayo, iikhompyutha zamanqaku, kunye neekhompyuter eziphathwayo. Impembelelo yememori ye-nickel metal hydride ibhetri ayibonakali kakhulu. Enye into kukuba ifuneka ngokukhawuleza kwaye ayifuni ukuhlawuliswa nge-photoelectric. Ngokuqhelekileyo, kungcono emva kokukhanya okwaneleyo.
umbane
Ibhetri yeLithium inamandla athile aphezulu kunye nokusebenza kakuhle kwebhetri. I-voltage yebhetri ye-lithium enye iphindwe kathathu ibhetri ye-nickel-metal hydride. Akukho siphumo sokukhumbula, sinokusetyenziswa kwaye sihlaziywe. Kodwa ayinakusetyenziselwa ukutshaja, ngoko ke ukutshaja nokukhupha amaxesha amaninzi kuya kuchaphazela ubomi bebhetri. Iibhetri zeLithium azifanelekanga ukugcina ixesha elide, kwaye ukugcinwa kwexesha elide kuya kulahlekelwa ngokusisigxina inxalenye yomthamo wabo. Kungcono ukutshaja umbane wama-40% kwaye uwugcine kwisikhenkcisi sefriji.
Indlela yokutshaja
Iimfuno zokutshaja iibhetri ze-lithium zihluke kwiibhetri ze-ni-CD / ni-MH, iibhetri ze-ni-CD / ni-MH zihlaziywa kwakhona iibhetri ze-lithium ezine-voltage enye ye-3.6V (ezinye iibhetri zingamakishwa njenge-3.7V). Njengoko unikezelo lwamandla luphuphuma, i-voltage yebhetri ye-lithium ikhula ngokuthe ngcembe, ekwangumqondiso wokuqinisekisa ukuba ibhetri ye-lithium igcwele kakhulu. Umenzi jikelele uncoma umbane wokutshaja we-4.2V (ibhetri ye-lithium enye). Ngokuqhelekileyo, iibhetri ze-lithium zihlawuliswa ngokunciphisa i-voltage kunye nangoku. Ukuba ufuna ukuhlawula ibhetri ye-lithium ngokwahlukileyo, kufuneka kuqatshelwe ukuba indlela yokutshaja yahlukile kwindlela yokutshaja yangoku ye-nickel-cadmium / i-nickel metal hydride ibhetri, kunye ne-nickel-cadmium / i-nickel metal hydride ishaja yebhetri ayikwazi esetyenzisiweyo.
