Qhov hnyav ntawm lub zog siab ceev lithium-ion roj teeb yog ib nrab ntawm nickel-cadmium lossis nickel-hlau hydride roj teeb ntawm tib lub peev xwm, thiab qhov ntim yog 20-30 feem pua ntawm nickel-cadmium thiab {{6} } feem pua ntawm nickel-hlau hydride.
Kev khiav hauj lwm voltage ntawm lithium-ion roj teeb monomer ntawm high voltage yog 3.7V (qhov nruab nrab), uas yog sib npaug rau peb nickel-cadmium los yog npib tsib xee-hlau hydride roj teeb txuas nrog hauv series.
Cov roj teeb uas tsis muaj kuab paug lithium-ion tsis muaj cov hlau tsis zoo xws li cadmium, txhuas, mercury thiab lwm yam.
Lithium-dawb lithium-ion roj teeb tsis muaj hlau lithium thiab yog li tsis raug rau cov kev txwv ntawm lub dav hlau thauj khoom uas txwv tsis pub nqa cov roj teeb lithium ntawm cov neeg caij dav hlau.
Raws li ib txwm muaj, lub sijhawm them thiab tawm ntawm cov roj teeb lithium-ion tuaj yeem tshaj 500 zaug, thiab lithium ferrous phosphate tuaj yeem ncav cuag 2000 zaug.
Lub cim xeeb tsis muaj txiaj ntsig tsis nco qab yog hais txog qhov tshwm sim uas lub peev xwm ntawm lub roj teeb txo qis thaum lub sij hawm them nqi hluav taws xob ntawm cov roj teeb nickel-cadmium. Cov roj teeb lithium-ion tsis muaj qhov cuam tshuam no.
Kev them nyiaj ceev ceev siv lub tshuab hluav taws xob tsis tu ncua thiab qhov hluav taws xob tsis tu ncua nrog lub ntsuas hluav taws xob ntawm 4.2V, uas tuaj yeem ua rau lub roj teeb lithium-ion tau them tag nrho hauv 1.5-2.5 teev; thiab lub roj teeb lithium phosphorus hlau tau tsim tshiab tuaj yeem them tag nrho hauv 35 feeb.
