Lithium polymer bateri

lithium polymer bhatiri

Lithium polymer bhatiri imhando yebhatiri rechargeable mune diki fomu chinhu. Aya mabhatiri akanakira nharembozha dzinoda anopfuura mawatts matatu asi asingasviki 3 watts, senge malaptop nenharembozha. Lithium polymer mabhatiri akatumidzwa kusanganiswa kwelithium ion uye mapolymers (chinhu chine mamorekuru makuru) anoumba kuvaka kwavo.

Iyo lithium polymer bhatiri yakagadzirwa uye yakagadzirwa nevaongorori mukupera kwema1980. Yekutanga lithium polymer bhatiri prototype yakagadziridzwa muna 1994 kuti ishandiswe mukurapwa nekukurumidza, uye anenge makore gumi mushure mekusikwa kwayo, yakashandiswa pasatellite uye spacecraft. Iyo lithium polymer bhatiri yakashandiswa munharembozha kubva 10, apo Sony yakagadzira yekutanga nhare mbozha inotengeswa uchishandisa lithium ion bhatiri.

Lithium polymer mabhatiri akasiyana nemabhatiri e-lithium ion nekuti haana chinoparadzanisa pakati peakanaka uye asina kunaka emagetsi. Iwo mapolymers anoshandiswa mukati meaya mabhatiri ane kuenderana kwakafanana neiyo jelly, ndicho chikonzero ivo vanowanzonzi gel masero. Lithium polymer mabhatiri anewo mukana wekusanyanya kuona kubuda kwe electrolyte zvichienzaniswa nemamwe marudzi emabhatiri e lithium ion nekuti hapana chinoparadzanisa chiripo.

Ngozi yekudonha kweelectrolyte inotoitika nemamwe asiri-lithium polymer modhi. Kunyange zvazvo bhatiri rakafanana nechitarisiko kune mamwe mabhatiri e-lithium ion, zvinhu zvinoshandiswa mukati maro zvakasiyana neaya echinyakare lithium ion mabhatiri. Mvura ye electrolyte inobatanidza materminals akanaka neasina kunaka mukati meyakajairika lithium ion bhatiri inoumbwa ne potassium hydroxide kana lithium hydroxide, iyo inopindirana ne graphite mune yakanaka electrode panguva yekuchaja.

Chimwe chikamu cheiyo inobatsira lithium ion bhatiri igraphite, iyo kuburikidza nemakemikari kuita ne electrolyte inoumba huturu hwakasimba hunodaidzwa kuti carbon dioxide pentoxide, inoshanda se insulator. Mune lithium polymer bhatiri, zvisinei, iyo electrolyte inoumbwa nepoly(ethylene oxide) uye poly(vinylidene fluoride), saka hapana chikonzero chegraphite kana chero imwe kabhoni. Mapolymers zvinhu zvakakura mamorekuru, anogona kuramba tembiricha yakanyanya uye kumwe kukora.

Mapolymers anoshandiswa mukati melithium polymer mabhatiri anopa zvinhu zvinogadzira gel-kufanana kuenderana kana ichienzaniswa nemamwe marudzi emabhatiri e lithium ion. Iyo electrolyte inoumbwa neiyo organic solvent inogona kugadzirwa isina lithium, saka inova iyo yakanyanya kudhura mhando yebhatiri.

Lithium polymer mabhatiri anoshandiswa mune akawanda maapplication nekuti anochinjika uye anogona kutsungirira tembiricha yakakwira kupfuura mamwe marudzi emabhatiri e lithium ion. Ivo zvakare vanorema zvishoma pane vakavatangira, izvo zvinobvumira mushandisi kubata nharembozha kwenguva refu pasina kusangana nekusagadzikana kana kurwadziwa mumawoko avo nemaoko.
