Sei lithium mabhatiri anoshandisa aluminium semagoko?

Zvikonzero zvikuru zvemabhatiri e-lithium kushandisa mabhomba ealuminium zvinogona kuongororwa zvakadzama kubva kune zvinotevera zvinhu, zvinoti lightweight, corrosion resistance, good conductivity, good processing performance, low cost, good heat dissipation performance, nezvimwewo.

1. Huremu

• Low density: The density yealuminium inenge 2.7 g/cm³, iyo yakanyanya kuderera pane iyo yesimbi, iyo inenge 7.8 g/cm³. Mumidziyo yemagetsi inoteedzera huwandu hwesimba uye huremu, senge nharembozha, malaptop, uye mota dzemagetsi, magomba ealuminium anogona kunyatso kudzikisa huremu hwese uye kugadzirisa kutsungirira.

2. Corrosion resistance

• Kugadziriswa kune yakakwirira-voltage nharaunda: Kushanda kwemagetsi e lithium battery positive electrode zvinhu, zvakadai se ternary zvinhu uye lithium cobalt oxide, yakakura (3.0-4.5V). Pane ichi chinogoneka, aruminiyamu ichagadzira dense aluminium oxide (Al₂O₃) passivation firimu pamusoro kudzivirira imwe corrosion. Simbi inoomeswa nyore nyore ne electrolyte pasi pekumanikidzwa kwakanyanya, zvichikonzera kukanganisa kwebhatiri kana kudonha.

• Kubatana kweElectrolyte: Aluminium ine kugadzikana kwakanaka kwemakemikari kune organic electrolytes, yakadai seLiPF₆, uye haigoni kuita panguva yekushandiswa kwenguva refu.

3. Conductivity uye kugadzirwa kwemaitiro

• Ikozvino muunganidzi wekubatanidza: Aluminium ndiyo inoshandiswa kune yakanaka electrode current collectors (zvakadai sealuminium foil). Iyo aluminium shell inogona kubatanidzwa zvakananga kune yakanaka electrode, kurerutsa chimiro chemukati, kuderedza kuramba, uye kugadzirisa simba rekufambisa.

• Shell conductivity zvinodiwa: Mune mamwe magadzirirwo ebhatiri, iyo aluminium shell chikamu chezvino nzira, yakadai secylindrical mabhatiri, ane zvose conductivity nekudzivirira mabasa.

4. Kugadzirisa kushanda

• Yakanakisa ductility: Aluminium iri nyore kutsika uye kutambanudza, uye inokodzera kugadzirwa kwakakura kwemaitiro akaomarara, akadai sealuminium-plastiki mafirimu emakona uye akapfava-pack mabhatiri. Magoko esimbi anonetsa kugadzira uye ane mutengo wakakwira.

• Chisimbiso chisimbiso: Aluminium shell welding teknolojia yakakura, yakadai se laser welding, iyo inogona kunyatsoisa chisimbiso che electrolyte, kudzivirira unyoro uye oksijeni kubva pakupinda, uye kuwedzera hupenyu hwebheteri.

5. Kutarisira kupisa

• Kupisa kwekushisa kwakanyanya: Thermal conductivity yealuminium (inenge 237 W / m·K) yakakwirira zvikuru kupfuura yesimbi (inenge 50 W / m · K), iyo inobatsira bhatiri kubvisa kupisa nokukurumidza pakushanda uye kuderedza dambudziko rekupisa kwemhepo.

6. Mari uye hupfumi

• Zvinhu zvakaderera uye mari yekugadzira: Mutengo wezvigadzirwa zvealuminium zvine mwero, uye kushandiswa kwesimba kushandiswa kwakaderera, iyo yakakodzera kugadzirwa kukuru. Kusiyana neizvi, zvinhu zvakadai sesimbi isina tsvina zvinodhura.

7. Kuchengetedza dhizaini

• Kuderedza kudzvinyirira: Mabhomba eAluminium anogona kusunungura mukati uye kudzivirira kuputika muchiitiko chekuwedzera kana kupisa kwemhepo nekugadzira mavharuvhu ekuchengetedza, akadai seCID flip structure yemabhatiri ecylindrical.

8. Indasitiri maitiro uye kuenzanisa

• Aluminium shells yakagamuchirwa zvakanyanya kubva pamazuva ekutanga ekutengesa kwe lithium bhatiri, seye 18650 bhatiri yakatangwa naSony muna 1991, ichigadzira ketani yakakura yeindasitiri uye zviyero zvehunyanzvi, zvichiwedzera kusimbisa nzvimbo yayo huru.

Pane nguva dzose kunze. Mune mamwe mamiriro akakosha, magomba esimbi anoshandiswawo:

Mune zvimwe zviitiko zvine simba rakawandisa remagetsi zvinodiwa, senge mamwe mabhatiri emagetsi kana kunyanyisa kwezvakatipoteredza maapplication, nickel-plated simbi makoko anogona kushandiswa, asi mutengo unowedzera huremu uye mutengo.

Mhedziso

Aluminium shells ave sarudzo yakanaka yelithium bhatiri mashembu nekuda kwehuwandu hwawo hwakanakira huremu huremu, corrosion resistance, good conductivity, easy processing, best heat dissipation uye mutengo wakaderera, kunyatso kuenzanisa kuita, kuchengetedza uye zveupfumi zvinodiwa.
