Ndeupi musiyano uripo pakati pepolymer lithium-ion mabhatiri uye lithium-ion mabhatiri?

1.Raw zvinhu

Polymer bhatiri inoreva kushandiswa kwezvinhu zvepolymer mune angangoita chimwe chezvikamu zvitatu zvikuru: positive electrode, negative electrode kana electrolyte. Polymer zvinoreva huremu hwemamorekuru, uye pfungwa yayo inoenderana mamorekuru madiki, polymer ine simba rakawanda, kusimba kwepamusoro uye kusimba kwepamusoro. Polymer bhatiri cathode zvinhu mukuwedzera kune kushandiswa inorganic komisheni ye lithium-ion mabhatiri, asiwo conductive polymer; polymer bhatiri electrolytes ari polymer electrolytes (yakasimba kana gel state) uye organic electrolyte, lithium-ion mabhatiri anoshandisa electrolyte.

2.Kuumba misiyano

Polymer lithium-ion mabhatiri anogona kutetepa, chero nzvimbo uye chero chimiro, chikonzero ndechekuti electrolyte yayo inogona kusimba kana gel mamiriro pane emvura, nepo lithium-ion mabhatiri anoshandisa electrolyte, kune goko rakasimba sepakeji yechipiri kuti igamuchire electrolyte. . Naizvozvo, izvi zvakare zvinoita kuti lithium-ion bhatiri riwedzere chikamu chehuremu.

3.Kachengeteka

Iyo yazvino polymer inonyanya kupfava pack bhatiri, uchishandisa aruminiyamu-yepurasitiki firimu segoko, kana yemukati organic electrolyte, kunyangwe mvura ichipisa kwazvo, haiputike, nekuti aluminium-plastiki firimu repolymer bhatiri rinoshandisa yakasimba kana gel mamiriro. pasina kubuda, kungoputika kwepanyama. Asi chero chinhu hachina mhedziso, kana nguva yenguva yakakwira zvakakwana, dunhu diki, bhatiri rinongoerekana rapisa kana kuputika hazvigoneke, nharembozha uye piritsi PC yekuchengetedza tsaona inokonzerwa nemamiriro ezvinhu aya. Uye lithium iron phosphate mabhatiri anga akaomesesa kuyedza kuchengetedza, kunyangwe mukudhumhana haaputike.

4.cell voltage

Sezvo mabhatiri epolymer anoshandisa zvinhu zvepolymer, anogona kugadzirwa muchitokisi akawanda-layer musanganiswa kuti awane high voltage, uye lithium-ion bhatiri masero nominal capacity is 3.6V, kuti uwane yakakwira voltage mukuita, zvinodikanwa kubatanidza maseru akawanda munhevedzano. kugadzira iyo yakanakira yakakwirira-voltage chikuva.

5.Conductivity

Iyo ionic conductivity yeiyo yakasimba electrolyte yepolymer lithium-ion bhatiri yakaderera. Parizvino, zvimwe zvinowedzera zvinonyanya kuwedzerwa kuti zviite gel electrolyte kuvandudza conductivity. Izvi zvakare zvinongowedzera itsva ionic conductivity, kusiyana ne lithium-ion mabhatiri, ayo anochengetedza kukosha kwakadzikama kwekutengesa pasina kukanganiswa nehutano hwezvinhu zvinobatsira.


electric wheelchair mabhatiri, mabhatiri-akabatanidzwa, monitor bhatiri voltage, B- ultrasound muchina bhatiri, solar simba bhatiri kuchengetedza, lithium bhatiri kambani, monitor bhatiri pfungwa, simba rekushandisa bhatiri pabhasikoro, mabhatiri ematochi madiki, monitor bhatiri laptop.
