Kuumbwa kwebhatiri re lithiamu

Kuumbwa kwezvinhu zvemabhatiri e lithium kunosanganisira zvinhu zvakanaka zve electrode, zvinhu zvisina kunaka zve electrode, zvinoparadzanisa, ma electrolytes, uye ma casing.

1. Pakati pezvinhu zve positive electrode, zvinhu zvinonyanya kushandiswa i lithium cobalt, lithium manganate, lithium iron phosphate uye zvinhu zve ternary (polymers ye nickel, cobalt uye manganese). Zvinhu zve positive electrode zvine chikamu chikuru (huwandu hwezvinhu zve positive ne negative electrode i3:1~4:1), nekuti mashandiro e positive electrode anokanganisa zvakananga mashandiro e lithium-ion battery, uye mutengo wayo unosarudzawo zvakananga mutengo webhatiri.
2. Pakati pezvinhu zvine electrode isina kunaka, natural graphite ne artificial graphite ndizvo zvinhu zvikuru zvine electrode isina kunaka parizvino. Zvinhu zvine anode zviri kuongororwa zvinosanganisira nitrides, polyaspartic acid, tin-based oxides, tin alloys, nano-anode materials, nezvimwe zvinhu zve intermetallic. Seimwe yezvinhu zvikuru zvina zvemabhatiri e lithium, zvinhu zvine electrode isina kunaka zvinoita basa rakakosha mukuvandudza kugona kwebhatiri uye mashandiro e cycle, uye zviri pakati penzvimbo dzepakati dzeindasitiri yebhatiri re lithium.
3. Zvinhu zve diaphragm zvinotarisa musika zvinonyanya kuve polyolefin diaphragms, izvo zvinogadzirwa zvakanyanya ne polyethylene ne polypropylene. Muchimiro che lithium battery separator, separator ndeimwe yezvinhu zvakakosha zvemukati. Kushanda kwe separator kunosarudza chimiro che interface uye resistance yemukati yebhatiri, izvo zvinokanganisa zvakananga kugona, kutenderera uye mashandiro ekuchengetedza ebhatiri. Separator ine performance yakanaka inoita basa rakakosha mukuvandudza mashandiro ese ebhatiri.
4. Electrolyte inowanzogadzirwa ne organic solvents dzakachena kwazvo, electrolyte lithium salts, zvinowedzerwa zvinodiwa nezvimwe zvinhu zvisina kucheneswa mune imwe nhanho pasi pemamwe mamiriro ezvinhu. Electrolyte inoita basa rekufambisa maion pakati pema electrodes akanaka neasina kunaka e lithium battery, inova vimbiso ye high voltage uye high specific energy ye lithium ion battery.
5. Kabati rebhatiri: rakakamurwa kuita kabati resimbi, kabati rearuminiyamu, kabati resimbi rakaputirwa nickel (remabhatiri ecylindrical), firimu rearuminiyamu-purasitiki (rakapfava), nezvimwewo, pamwe chete nekabati rebhatiri, iro ririwo nzvimbo dzakanaka nedzisina kunaka dzebhatiri.
6. Nheyo yekushanda kweBattery
7. Kana bhatiri rachajwa, maion e-lithium anogadzirwa pa positive electrode yebhatiri, uye maion e-lithium anogadzirwa anotama kuenda ku negative electrode kuburikidza ne electrolyte. Maumbirwo ekabhoni e electrode isina simba ane ma pores akawanda, uye maion e-lithium anosvika ku negative electrode anoiswa muma micropores e carbon layer. Maion e-lithium akawanda anoiswa, ndipo panowanikwa mukana wekuchaja wakakwira. Kana bhatiri rabuda, maion e-lithium akabatanidzwa mu carbon layer ye negative electrode anobuda odzokera ku positive electrode. Maion e-lithium akawanda anodzokera ku positive electrode, ndipo panowanikwa mukana wekuburitsa. Kazhinji, mukana wekuburitsa unoreva mukana wekuburitsa. Munguva yekuchaja nekubudisa bhatiri re lithium, maion e-lithium ari muchimiro chekufamba kubva ku positive electrode kuenda ku negative electrode. Kana mufananidzo webhatiri re lithium uchienzaniswa nechigaro chinotenderera, magumo maviri echigaro chinotenderera ndiwo maelectrodes akanaka neakaipa ebhatiri, uye maion e-lithium akafanana nevatambi, achimhanya-mhanya pakati pemagumo maviri echigaro chinotenderera. Saka mabhatiri e-lithium anonziwo mabhatiri echigaro chinotenderera.
