Lithium-ion roj teeb thiab roj teeb npib tsib xee-cadmium sib txawv ntawv yog dab tsi?

Lithium-ion roj teeb thiab npib tsib xee-cadmium roj teeb muaj muaj xya lub ntsiab sib txawv me ntsis:

1, khoom siv: cov khoom rau lithium-ion roj teeb (graphite) tsis zoo, zoo electrode cov lithium uas muaj tebchaw; zoo electrode cov roj teeb npib tsib xee-cadmium npib tsib xee hmoov oxide thiab graphite hmoov muaj li yam tej, tsis zoo los ntawm cadmium oxide thiab oxide hlau hmoov hom tej yam.

2, Txojcai: muaj ntau tshaj rau ib lub thawv xwb lub roj teeb lithium-ion, ua hauj lwm tsis khi tshuaj yog muaj tshuaj lom neeg, thaum lub roj teeb yuav them, lub generated rau lub cathode ntawm cov roj teeb lithium-ion, lithium ion zog tom qab cov ntsha mus rau ntawm cathode. Thiab ua cathode cov nyob hauv tus qauv layered, nws yeej muaj qhov ntxeem tau, kom mus zoo raws cov cathode, lithium-ion yog kos rau hauv cov dej txeem txheej, embedded lithium ion them peev xwm siab dua. Mob(nurses), thaum twg koj raws lub roj teeb (ntawd ces yog peb siv roj teeb), kos rau lub cathode, ib tug lithium-ion cov txheej raug tshem tawm thiab lub zog rov los rau cathode. Rov qab mus rau qhov zoo electrode txog lithium-ion ntau ntau kws tau. Npib tsib xee CD roj teeb ua hauj lwm yuav tsum fais tshuaj tshua, them Shi nrog hlau rau cathode, thiab cathode muaj II oxidation npib tsib xee thiab hydrogen oxidation sodium kua rau hauv qhov dej tsis ua hydrogen npib tsib xee oxidation thiab cov pa hauv paus ion, fais fab tuag mus rau tshuaj lom neeg zog; hydrogen paug Shi nyob rov tsis CD (Cd) thiab hydrogen oxidation sodium (NaOH) nyob rau hauv cov hydrogen pa hauv paus ion (OH-) ntawm synthesis hydrogen oxidation CD, thiab txuas nrog rau anode Shang, hos tseem tso hauv, tshuaj zog ua rau muaj hwj huam;
