Iingxaki eziqhelekileyo kunye nezizathu zeebhetri ze-lithium

Iimpazamo eziqhelekileyo kunye nezizathu zeebhetri ze-lithium zezi zilandelayo:

1. Umthamo webhetri ephantsi

Oonobangela:
a. Ubungakanani bezinto eziqhotyoshelweyo zincinci kakhulu;
b. Ubungakanani bezinto eziqhotyoshelweyo kumacala omabini esiqhekeza sepali zihluke kakhulu;
c. Ipali yaphukile;
d. I-electrolyte incinci;
e. I-conductivity ye-electrolyte iphantsi;
f. Ayilungiswanga kakuhle;

g. I-porosity ye-diaphragm encinci;
h. Incamathela iyaguga → into encamathelayo iyawa;
i. I-core ejikelezayo inzima kakhulu (ayiyomisiwe okanye i-electrolyte ayingenanga);

j. Izinto eziphathekayo zinomthamo omncinci omncinci.

2. Ukumelana okuphezulu kwangaphakathi kwebhetri

Oonobangela:
a. I-Welding ye-electrode engalunganga kunye nethebhu;
b. I-Welding ye-electrode efanelekileyo kunye nethebhu;
c. I-Welding ye-electrode efanelekileyo kunye ne-cap;
d. Ukuwelda kwe-electrode engalunganga kunye negobolondo;
e. Ukuchasana okukhulu koqhagamshelwano phakathi kwe-rivet kunye ne-platen;
f. I-electrode efanelekileyo ayinayo i-agent conductive;
g. I-electrolyte ayinayo ityuwa ye-lithium;
h. Ibhetri ine-short-circuited;
i. I-porosity yephepha lokwahlula lincinci.

3. Umbane ophantsi webhetri

Oonobangela:

a. Ukusabela kwecala (ukubola kwe-electrolyte; ukungcola kwi-electrode efanelekileyo; amanzi);

b. Akwenziwanga kakuhle (ifilimu ye-SEI ayenziwanga ngokukhuselekileyo);

c. Ukuvuza kwebhodi yesekethe yoMthengi (ebhekisa kwiibhetri ezibuyiselwe ngumthengi emva kokucubungula);

d. Umthengi akazange abone i-welding njengoko kuyimfuneko (iiseli ezicutshungulwayo ngumthengi);

e. iibhula

f. i-micro-short circuit.

4. Izizathu zokutyeba ngokugqithisileyo zezi zilandelayo:

a. Ukuvuza kwe-weld;

b. Ukubola kwe-Electrolyte;

c. Ukomisa ukufuma;

d. Ukusebenza kakubi kokutywinwa kwe-cap;

e. Udonga lweqokobhe lungqindilili kakhulu;

f. Iqokobhe lingqindilili kakhulu;

g. iziqwenga zepali ezingadityaniswanga; idiaphragm ingqindilili kakhulu).

5. Ukwakheka kwebhetri okungaqhelekanga

a. Akwenziwanga kakuhle (ifilimu ye-SEI ayiphelelanga kwaye ixinene);

b. Ubushushu bokubhaka buphezulu kakhulu → ukuguga kwesibophelelo → ukuhluba;

c. Umthamo othile we-electrode engalunganga uphantsi;

d. Umnqwazi uyavuza kwaye intsimbi iyavuza;

e. I-electrolyte ichithwa kwaye i-conductivity iyancitshiswa.

6. Ukudubula kwebhetri

a. Isingxobo esingaphantsi sinempazamo (kubangela umrhumo ogqithisileyo);

b. Isiphumo sokuvala i-diaphragm sibi;

c. Isiphaluka esifutshane sangaphakathi.

7. Ibhetri yesekethe emfutshane

a. Uthuli lwezinto;

b. Yaphukile xa iqokobhe lifakwe;

c. I-Scraper (iphepha le-diaphragm lincinci kakhulu okanye alifakwanga ngokufanelekileyo);

d. Ukujikajika okungalinganiyo;

e. Ayisongwanga kakuhle;

f. Kukho umngxuma kwi-diaphragm.

8. Ibhetri iqhawukile.

a. Iithebhu kunye ne-rivets azixutywanga ngokufanelekileyo, okanye indawo ye-welding esebenzayo incinci;

b. Isiqwenga sokudibanisa siphukile (isiqwenga sokudibanisa sifutshane kakhulu okanye siphantsi kakhulu xa i-spot i-welding kunye ne-pole piece).
