Flexible lipo bhatiri

Kuwanikwa uku kwakaita kuti vamwe vaongorori vagadzire mabhatiri eLi-ion matsva anochinjika ayo anoshandisa zvinhu zvisina kumira zvakanaka zvakadai selastic polymers neorganic liquids pachinzvimbo chemagetsi anobvira moto eelectrolyte (chinhu chinoita kuti ayoni afambe pakati pemaelectrodes maviri).Makambani akawanda akagadzira zvigadzirwa zvinoenderana pazvishandiso izvi zvitsva, uye chinyorwa ichi chichaongorora mhando mbiri dzemabhatiri anochinjika anochajika aripo pari zvino kushandiswa kwekutengesa.

Rudzi rwekutanga runoshandisa electrolyte yakajairika asi ine polymer composite separator pachinzvimbo cheyakajairika porous polyethylene kana polypropylene zvinhu. Izvi zvinobvumira kuti ikotame kana kuumbwa kuita mafomu akasiyana pasina kutsemuka. Semuenzaniso, Samsung nguva pfupi yadarika yakazivisa kuti vakagadzira bhatiri rakadaro rinogona kuchengetedza chimiro charo kunyangwe rapetwa nepakati. Aya mabhatiri anodhura kupfuura echinyakare asi anogona kugara kwenguva refu nekuti pane kushoma kwemukati kuramba kubva kune akakora maelectrodes uye separators. Nekudaro, imwe dhizaini ndeye kushomeka kwesimba ravo: Vanogona kungochengeta simba rakawanda sebhatiri reLi-ion rakafanana saizi uye haigone kuchajwa nekukurumidza.

Iri rudzi rweLi-ion bhatiri parizvino rinoshandiswa muWearable Sensors kutarisa zviratidzo zvakakosha zvemuviri, asi inogona zvakare kubatanidzwa muzvipfeko zvakangwara. Semuyenzaniso, Cute Circuit inogadzira dhirezi rinoteedzera kusvibiswa kwemhepo uye rinozivisa vashandisi kuburikidza nechiratidziro che LED kuseri kana paine mazinga akakwira munharaunda yeanoripfeka. Kushandisa rudzi urwu rwebhatiri rinoshanduka kwaizoita kuti zvive nyore kubatanidza masensa zvakananga muzvipfeko pasina kuwedzera kuwanda kana kusagadzikana.

Lithium mabhatiri anoshandiswa zvakanyanya muzvigadzirwa zvevatengi senge mbozhanhare nemalaptops, asi kuvandudzwa kwekwaniso yayo (simba, uremu) kunogona kutungamira kune zvinobatsira zvikumbiro senge michina yekurapa uye mota dzemagetsi. Sezvo mabhatiri mazhinji achishandisa casing yakaomarara ine maelectrodes akaiswa mukati, pakave netsvakiridzo yakadzama yekuti bhatiri rinochinjika ringagadziriswe izvo zvinobvumira maumbirwo akasiyana uye midziyo ingangove ine simba rakawanda.

Motokari dzemagetsi dziripo pari zvino dzine huwandu hushoma nekuda kwekuderera kwesimba remagetsi emabhatiri anokonzerwa nekushandisa macasings akaomarara. Mabhatiri anochinjika anogonawo kupfekwa pazvipfeko kana kuputirwa munzvimbo dzisina kujairika, izvo zvinovhura mikana mitsva yehunyanzvi hwekupfeka. Pamusoro pezvo, kuchinjika kukuru kunoreva kuti mabhatiri anogona kuchengetwa munzvimbo dzakasimba uye anoenderana nezvimiro zvisina kujairika; izvi zvinogona kukonzera mabhatiri ane saizi diki pane akayerwa zvakafanana ekare.

Results:

Bhatiri rinochinjika rinoshandisa foil yesimbi pachinzvimbo chemagetsi akaomarara rakagadzirwa nevaongorori vepaYunivhesiti yeCalifornia, Berkeley. Dhizaini ine chivimbiso chekuita zvirinani pane zvishandiso zvazvino nekuti inoumbwa nemapepa matete akati wandei akaturikidzana, izvo zvinoguma nekuwanda kwesimba uku richiramba richinyatso shanduka. Kuedza kwapfuura kushandisa zvimwe zvinhu zvakaita segraphene kwakakundikana nekuda kwekusasimba kwezvimiro izvi uye kushomeka kwavo kwe scalability. Nekudaro, iyo nyowani simbi foil dhizaini inotevera chimiro chakafanana kune ekutengesa lithium-ion mabhatiri uye inobvumira aya mayuniti kuti abudiswe pachiyero cheindasitiri pasina kuomerwa.

Applications:

Flexible lipo mabhatiri anogona kutungamira kumidziyo yekurapa iyo inopfekwa nyore nyore pamuviri, mota dzemagetsi dzine hukuru hwekutyaira, inopfeka tekinoroji isingakanganise kufamba, uye mamwe maapplication anotora mukana wekuwedzera kuchinjika.

mhedziso:

Tsvagiridzo paYunivhesiti yeCalifornia Berkeley yakagadzira bhatiri rinochinjika rakagadzirwa neakarongedzerwa simbi foil sheet pasina kushandisa isina kusimba graphene zvinhu. Iyi dhizaini inopa yakawedzera simba density pane yazvino zvishandiso ichiri kunyatso shanduka. Flexible lipo mabhatiri zvakare ane anogona kunyorera mumotokari dzemagetsi, tekinoroji inopfeka, uye dzimwe nzvimbo uko kuwedzera kuchinjika kunobatsira.
