Tej teeb meem txhaum cai thiab ua rau cov roj teeb lithium

Feem ntau faults thiab ua rau lithium roj teeb yog raws li nram no:

1. Tsawg roj teeb muaj peev xwm

Ua rau:
a.Tus nqi ntawm cov khoom txuas yog tsawg dhau;
b.Tus nqi ntawm cov khoom txuas ntawm ob sab ntawm tus ncej yog qhov sib txawv heev;
c.Cov ncej ncej tawg;
d.Cov electrolyte tsawg dua;
e.Lub conductivity ntawm electrolyte yog tsawg;
f.Tsis npaj zoo;

g.Lub porosity ntawm lub diaphragm yog me me;
h.Cov nplaum nplaum yog aging → cov khoom txuas nrog poob;
i.Cov tub ntxhais winding yog tuab heev (tsis qhuav los yog cov electrolyte tsis nkag);

j.Cov khoom muaj lub peev xwm me me.

2. Siab sab hauv tsis kam ntawm roj teeb

Ua rau:
a.Vuam ntawm qhov tsis zoo electrode thiab tab;
b.Vuam ntawm qhov zoo electrode thiab tab;
c.Vuam ntawm qhov zoo electrode thiab cap;
d.Vuam tsis zoo electrode thiab plhaub;
e.Kev sib cuag loj ntawm rivet thiab platen;
f.Qhov zoo electrode tsis muaj tus neeg sawv cev conductive;
g.Cov electrolyte tsis muaj lithium ntsev;
h.Lub roj teeb tau luv luv;
i.Lub porosity ntawm daim ntawv cais yog me me.

3. Tsawg roj teeb voltage

Ua rau:

a.Cov tshuaj tiv thaiv sab (decomposition ntawm electrolyte; impurities hauv qhov zoo electrode; dej);

b.Tsis zoo tsim (SEI zaj duab xis tsis tsim kom muaj kev nyab xeeb);

c.Cov neeg siv khoom Circuit Court board to (xws li cov roj teeb xa rov qab los ntawm tus neeg siv khoom tom qab ua tiav);

d.Cov neeg siv khoom tsis pom qhov vuam raws li qhov xav tau (cov xov tooj ua tiav los ntawm tus neeg siv khoom);

e.burrs;

f.micro-short circuit.

4. Yog vim li cas rau over-thickness yog raws li nram no:

a.Weld to;

b.Electrolyte decomposition;

c.Tsis qhuav dej;

d.Tsis zoo sealing kev ua tau zoo ntawm lub hau;

e.Plhaub phab ntsa tuab heev;

f.Plhaub tuab heev;

g.ncej puab tsis compacted;diaphragm tuab heev).

5. Kev tsim cov roj teeb tsis zoo

a.Tsis zoo tsim (SEI zaj duab xis yog tsis tiav thiab ntom);

b.Ci kub siab dhau → khi aging → stripping;

c.Lub peev xwm tshwj xeeb ntawm qhov tsis zoo electrode yog tsawg;

d.Lub kaus mom leaks thiab weld leaks;

e.Cov electrolyte yog decomposed thiab cov conductivity yog txo.

6. Roj teeb tawg

a.Lub subcontainer yog faulty (ua rau overcharge);

b.Cov nyhuv kaw diaphragm tsis zoo;

c.Internal luv Circuit Court.

7. Roj teeb luv luv

a.Khoom siv plua plav;

b.tawg thaum lub plhaub raug ntsia;

c.Scraper (daim ntawv diaphragm me dhau los yog tsis zoo padded);

d.Tsis sib xws winding;

e.Tsis qhwv zoo;

f.Muaj ib lub qhov nyob rau hauv lub diaphragm.

8. Lub roj teeb raug txiav.

a.Cov tabs thiab rivets tsis welded kom zoo, los yog qhov chaw vuam qhov chaw me me;

b.Cov khoom sib txuas yog tawg (qhov txuas txuas yog luv dhau los yog qis dhau thaum qhov chaw vuam nrog cov ncej).
