Zvinetso zvakajairika uye zvinokonzeresa mabhatiri e lithium

Izvo zvinowanzoitika kukanganisa uye zvikonzero zve lithium mabhatiri ndeaya anotevera:

1. Kuderera kwebhatiri simba

Zvinokonzera:
a. Kuwanda kwezvinhu zvakasungirirwa zvishoma;
b. Huwandu hwezvinhu zvakanamirwa pamativi ese echigamba chakasiyana zvakasiyana;
c. Bango raputswa;
d. Iyo electrolyte ishoma;
e. Iko conductivity ye electrolyte yakaderera;
f. Haina kunyatsogadzirirwa;

g. Iyo porosity ye diaphragm idiki;
h. Iyo yekunamatira iri kuchembera → chinhu chekunamatira chinodonha;
i. Mhepo inomonereka yakanyanya kukora (isina kuomeswa kana iyo electrolyte haina kupindwa);

j. Nyaya yacho ine diki chaiyo kugona.

2. Kupikisa kwemukati kwebheteri

Zvinokonzera:
a. Welding ye electrode yakaipa uye tab;
b. Welding ye electrode yakanaka uye tab;
c. Welding ye electrode yakanaka uye cap;
d. Welding ye electrode yakaipa uye shell;
e. Yakakura kusangana kushorwa pakati pe rivet uye platen;
f. Iyo yakanaka electrode haina conductive agent;
g. Iyo electrolyte haina lithium munyu;
h. Bhatiri rave pfupi-circuited;
i. Iyo porosity yepepa yekuparadzanisa idiki.

3. Low bhatiri voltage

Zvinokonzera:

a. Maitiro eparutivi (kuparara kwe electrolyte; kusvibiswa mune yakanaka electrode; mvura);

b. Haina kuumbwa zvakanaka (SEI firimu haina kuumbwa zvakachengeteka);

c. Customer's circuit board leakage (zvichireva mabhatiri akadzorerwa nemutengi mushure mekugadzirisa);

d. Mutengi haana kuona welding sezvinodiwa (masero anogadziriswa nemutengi);

e. burrs;

f. micro-short circuit.

4. Zvikonzero zvekufuta zvakanyanya ndezvizvi:

a. Weld leakage;

b. Electrolyte kuora;

c. Undrying unyoro;

d. Kusaita chisimbiso chekuvhara chivharo;

e. Shell wall yakanyanyisa;

f. Shell yakanyanya kukora;

g. mapango asina kuumbwa; diaphragm yakakora zvakanyanya).

5. Kuumbwa kwebhatiri kusina kujairika

a. Haina kuumbwa zvakanaka (SEI firimu haina kukwana uye dense);

b. Tembiricha yekubikira yakanyanya → binder kuchembera → kubvisa;

c. Iyo chaiyo kugona kweiyo yakaipa electrode yakaderera;

d. Chivharo chinodonha uye weld inodonha;

e. Iyo electrolyte yakaora uye conductivity inoderedzwa.

6. Battery kuputika

a. Iyo sub-container inokanganisa (inokonzera kuwandisa);

b. Iyo diaphragm yekuvhara maitiro haina kunaka;

c. Internal short circuit.

7. Battery short circuit

a. Material dust;

b. Yakaputsika kana goko raiswa;

c. Scraper (pepa rediaphragm rakanyanya kuduku kana kuti risina kunyatsoputirwa);

d. Uneven winding;

e. Haina kuputirwa zvakanaka;

f. Pane gomba mu diaphragm.

8. Bhatiri rakabviswa.

a. Iwo ma tabo uye rivets haana kusungirirwa zvakanaka, kana inobudirira welding spot nzvimbo idiki;

b. Chidimbu chekubatanidza chakatyoka (chidimbu chekubatanidza chakanyanya kupfupika kana chakanyanya kuderera kana nzvimbo welding nechidimbu chedanda).
