Lithium bhatiri 18650 uye yese-polymer bhatiri

Lithium bhatiri 18650 uye yese-polymer bhatiri

Ngatitaure nezve 18650 uye mabhatiri epolymer nhasi!

Pano, ngatitarisei iyo 18650 bhatiri cell. Chimiro chayo chemukati chinosanganisira yakanaka electrode lithium compound, electrolyte membrane iri pakati, uye negative electrode carbon.

Ikozvino yakajairwa 2000-3000mAh chiyero chinotevera-chizvarwa mabhatiri, Deronne, Samsung, Panasonic, Sanyo, LG, uye mamwe mabhatiri pamusika, iyo yemukati cathode zvinhu yakagadziridzwa zvizere kubva kuchizvarwa chekutanga LiCoO2 lithium cobalt oxide kune ternary material, zita remakemikari NdiLiNi-Co-MnO2 nickel cobalt manganese.

Mabhenefiti akananga: hupenyu hwesevhisi hurefu, zvakachengeteka, kuita zvirinani. Kutaura nezve izvi, Prismatic square nyoro pasuru yakarongedzerwa nhare mbozha mabhatiri anogadzirwawo neLiNi-Co-MnO2 nickel-cobalt-manganese zvinhu, asi zvakasiyana nemabhokisi e18650 Cylindrical.

"Polymer yese" inoreva kushandiswa kwepolymer kugadzira network yegel mukati mesero uyezve kubaya electrolyte kuita electrolyte.

Kunyangwe mabhatiri e "polymer ese" achiri kushandisa maelectrolyte emvura, huwandu hwacho hudiki, hunovandudza kuchengetedzwa kwemabhatiri e-lithium-ion.

Kubva pane chimwe chinhu, mabhatiri epolymer anoreva mabhatiri e-lithium-ion anoshandisa aluminium-plastiki yekurongedza firimu seyekunze yekurongedza, iyo inowanzozivikanwa semabhatiri e-soft-pack. Iri firimu rekurongedza rine matatu matatu: iyo PP layer, Al layer, uye nylon layer. Nekuti PP nenaironi mapolymer, iyi inonzi bhatiri repolymer.

Ngatienzanise zvakanakira uye zvakaipira zvezviviri izvi:

1. mutengo

Mutengo wepasi rose we18650 ungangoita 1USD/pcs. Kana ikaverengerwa zvinoenderana ne2Ah, iri kwese kwese 3RMB/Ah. Mutengo wepolymer lithium mabhatiri ndeye 4RMB/Ah kune yakaderera-magumo cottage mafekitori, 5~7RMB/Ah yepakati-renji, uye inodarika 7RMB/Ah yepakati-kusvika-yepamusoro yekupedzisira.

2. Inogona kugadzirwa

SONY yagara ichida kugadzira mabhatiri e-lithium-ion senge alkaline mabhatiri. Kune chaiwo indasitiri zviyero, senge mabhatiri eAA uye mabhatiri eAA, akafanana pasi rese. Nekudaro, imwe yemabhenefiti akakosha emabhatiri e-lithium-ion ndeyekuti anogona kugadzirwa zvinoenderana nezvinodiwa nevatengi, uye hapana chiyero chakafanana. Parizvino, iyo lithium-ion bhatiri indasitiri inongova neyakajairwa modhi ye18650, uye mamwe acho akavakirwa pavatengi. Saizi yezvinodiwa inogadzirwa.

3. chibatiso

Tinoziva kuti pasi pemamiriro ezvinhu akanyanya (zvakadai sekuwedzera, kupisa kwakanyanya, nezvimwewo), mabhatiri e-lithium-ion achava nechisimba chemakemikari maitiro mukati uye anobudisa gasi rakawanda. Bhatiri re18650 rinoshandisa goko resimbi rine rimwe simba. Kana mhepo yemukati inosvika pane imwe nhanho, ganda resimbi rinoputika, zvichikonzera njodzi yakaipa yekuchengetedza.

Ichi ndicho chikonzero kamuri inoyedzwa bhatiri re18650 kazhinji inofanirwa kuchengetedzwa nezvikamu, uye hapana anogona kupinda panguva yekuyedzwa. Mabhatiri epolymer haana dambudziko iri, kunyange mumamiriro ezvinhu akaipisisa, nekuda kwesimba rakaderera refirimu rekuputira; chero bedzi mhepo yemhepo yakakwira zvishoma, ichaputika uye haizoputika. Nyaya yakaipisisa ndeyekupisa. Saka maererano nekuchengetedza, mabhatiri epolymer ari nani pane 18650 mabhatiri.

18650 uye mabhatiri epolymer ese ari maviri lithium mabhatiri. Parizvino, 18650 inoshandiswa zvakanyanya mumusika we lithium iron phosphate, lithium manganate, uye ternary. Mhepo yezita ndeye 3.8V, uye iyo yakawanda inogona kusvika 4.2V kana ikashandiswa. Yakaderera voltage inogona kusvika 2.5V, hapana ndangariro mhedzisiro, uye nzvimbo yekushandisa yakakura. Iyo tekinoroji simba rekugadzirwa kwemumba rinokwanisawo, uye rakakodzera kugadzirwa kwemumba. Mabhatiri epolymer andaona anonyanya kupfava mapaketi. Kune masimba uye masimba marudzi. Izvo zvinhu zvakafanana ne18650, kunze kwekuti 18650 igoko resimbi isina tsvina, uye iyo polima iganda realuminium-plastiki firimu. Inokodzera kugadzirwa kwemaindasitiri uye kutakura-magetsi.

Kazhinji, 18650 uye mabhatiri epolymer ane zvakanakira, uye kunaka kwebhatiri kunoenderana nehunyanzvi hwemugadziri.
