Kunzwisisa Iyo Inoputika Ngozi yePolymer Lithium-Ion Mabhatiri

Zvichienderana nerudzi rwe electrolyte inoshandiswa, mabhatiri e-lithium-ion akaiswa mumabhatiri e-lithium-ion (LIB) uye mabhatiri e-polymer lithium-ion (PLB), anozivikanwawo semabhatiri e-lithium-ion epurasitiki.

PLBs inoshandisa anode imwechete uye cathode zvinhu semvura lithium-ion mabhatiri, kusanganisira lithium cobalt oxide, lithium manganese oxide, ternary zvinhu, uye lithium iron phosphate ye cathode, uye graphite yeanode. Musiyano mukuru uri muelectrolyte inoshandiswa: PLBs dzinotsiva mvura ye electrolyte nepolymer electrolyte yakasimba, inogona kuva "yakaoma" kana "gel-like." Mazhinji maPLB parizvino anoshandisa polymer gel electrolyte.

Zvino, mubvunzo unomuka: mabhatiri e-polymer lithium-ion anoputika chaizvo? Tichifunga nezvehukuru hwavo hudiki uye huremu huremu, maPLB anoshandiswa zvakanyanya mumalaptops, mafoni, uye mamwe magetsi anotakurika. Nezvishandiso izvi zvinowanzotakurwa, kuchengetedzwa kwavo kwakakosha. Saka, kuchengetedzwa kwePLB kwakavimbika sei, uye ivo vanoisa njodzi yekuputika?

1. PLBs anoshandisa gel-se electrolyte, yakasiyana kubva kumvura electrolyte mumabhatiri e-lithium-ion. Iyi gel-yakafanana neelectrolyte haiviri kana kuburitsa gasi rakawanda, nekudaro ichibvisa mukana wekuputika kwechisimba.
2. Lithium mabhatiri anowanzo kuuya nebhodhi rekudzivirira uye anti-kuputika mutsara wekuchengetedza. Zvisinei, kushanda kwavo kunogona kuganhurirwa mumamiriro ezvinhu akawanda.
3. PLBs anoshandisa aluminium epurasitiki inochinjika kurongedza, kupesana nesimbi casing yemaseru emvura. Kana iri nyaya dzekuchengetedza, dzinowanzozvimba pane kuputika.
4. PVDF, sechinhu chegadziriro yePLBs, inoita zvakanaka.

Chengetedzo Yekuchengetedza yePLBs:

• Short Circuit: Inokonzerwa nemukati kana kunze zvinhu, kazhinji panguva yekuchaja. Kusabatana kwakashata pakati pemahwendefa ebhatiri kunogonawo kutungamirira kumatunhu mapfupi. Kunyange zvazvo mabhatiri akawanda e-lithium-ion achiuya nemaseketi ekudzivirira uye mitsara yekudzivirira-kuputika, izvi zvingasashanda nguva dzose.
• Overcharging: Kana PLB ichichajwa nevoltage yakawandisa kwenguva yakareba, inogona kukonzera kupisa kwemukati nekumanikidza kuvaka-up, zvichitungamira mukuwedzera uye kuputika. Kuwedzeresa uye kuburitsa kwakadzika kunogona zvakare kukanganisa zvisingagadzirise chimiro chebhatiri, zvichikanganisa hupenyu hwayo zvakanyanya.

Lithium inoshanda zvakanyanya uye inogona kubata moto zviri nyore. Munguva yekuchaja uye kuburitsa, kuenderera kunoramba kuchipisa kwebhatiri uye kuwedzera kwemagasi anogadzirwa kunogona kuwedzera kudzvanywa kwemukati. Kana iyo casing ikakuvadzwa, inogona kutungamira mukudonha, moto, kana kunyange kuputika. Zvakadaro, maPLB anogona kuzvimba pane kuputika.

Zvakanakira zvePLBs:

1. High kushanda voltage pasero.
2. Huru kugona density.
3. Minimal self-discharge.
4. Hupenyu hurefu hwekutenderera, pamusoro pe500 cycles.
5. No memory effect.
6. Kuita kwakanaka kwekuchengetedza, uchishandisa aluminium plastiki inochinjika kurongedza.
7. Ultra-yakaonda, inogona kukwana munzvimbo dzakakura-kadhi rechikwereti.
8. Lightweight: Hapana chikonzero chesimbi casing.
9. Huru huwandu huchienzaniswa neakaenzana saizi lithium mabhatiri.
10. Kuderera kwemukati kupikisa.
11. Excellent discharge maitiro.
12. Yakareruka kudzivirira bhodhi dhizaini.

Zvakaipa zvePLBs:

1. Mutengo wekugadzira wakakwira.
2. Kudiwa kwedziviriro yedunhu.
