Enzanisa ma supercapacitor nemabhatiri, sezvakaratidzwa mubhatiri repamusoro-soro rine hutatu hwakasiyana hwemagetsi emagetsi, ese ari maviri akakwira simba density, uye yakakwirira simba density. Kwakabva: Iripi American Chemistry Society, yakafanana nekubudirira mune yebhatiri tekinoroji, asi haisi bhatiri. Nhoroondo ye Nanotekinstruments, Inc.

uye makambani ayo, Angstronmaterials, Inc. yeOhton, yakagadzirwa New specification, inoshandiswa kugadzira midziyo yekuchengetedza simba, zvichienderana nekukurumidza kuvhara kwenhamba yakawanda yelithium ions mu electrode, iyi electrode ine guru graphene pamusoro. Ichi chishandiso chekuchengetedza simba chinogona kuratidza kubatsira zvakanyanya kumotokari dzemagetsi, izvo zvinogona kuderedza kuchaja nguva, kupfupikiswa kubva isingasviki miniti kubva pamaawa.

Mamwe maapplication anogona kusanganisira kuchengetedzwa kwesimba rekuchengetedza (semuenzaniso, kuchengetedza solar uye simba remhepo) uye smart grids. Vatsvakurudzi vakataura kuti chigadzirwa chitsva ichi chinonzi lithium ion chekuchinjana bhatiri ye graphene pamusoro pebasa, kana kuti zviri nyore, bhatiri repamusoro-mediated (SMCS: Surface-Mediatedcells). Kunyange zvazvo michina yemazuva ano inoshandisa zvinhu zvisina kuvhurwa uye zvivakwa, zvinogona kutopfuura lithium-ion mabhatiri uye supercapacitors.

Ichi chigadzirwa chitsva chinogona kupa 100 kilowatts pa kilowatt yebhatiri, 100 nguva yakakwirira kupfuura yekutengeserana lithium-ion mabhatiri, 10 nguva yakakwirira kudarika supercapacitor. Iyo yakakwira density yemagetsi, iyo inokurumidza kukurumidza kufambisa simba (inogona kukonzera kukurumidza kuchaja kumhanya). Pamusoro pezvo, bhatiri idzva iri rinogona kuchengetedza simba remagetsi e160 watts pakirogiramu yebhatiri, inofananidzwa nebhatiri rekutengesa lithium-ion bhatiri, rakapetwa ka30 kupfuura yechinyakare supercapacitor.

Iyo yakakura kuwanda kwesimba, iyo yakawanda simba inogona kuchengetwa, iyo yakawanda simba inochengetwa (ine yakareba kutyaira mileage yemotokari dzemagetsi). Kana paine uremu hwemidziyo yakafanana, bhatiri repamusoro-mediated bhatiri uye lithium-ion mabhatiri anogona kushandiswa kumotokari dzemagetsi, uye muvambi weNano Instrument uye Angerstron Materials Company Joint muvambi Jiang Bauz (Borz.jang) Zvinonzi bhatiri redu rinopindirana nepamusoro rakafanana neyezvino lithium-ion bhatiri, inogona kuwedzera kuwedzera iyo simba densi.

Zvisinei, mumutemo, mabhatiri epamusoro-soro anogona kubhadharwa mumaminitsi mashomanana (angave asingasviki miniti imwe chete), pane maawa, sezvakangoita bhatiri re lithium-ion rinoshandiswa mumotokari dzemagetsi. Jiang Bauldz nemumwe wake muNanotechnology Instrument Co., Ltd.

uye Angersmia Material Company yakaburitsa chidzidzo ichi, chinova chidzidzo chechizvarwa chinotevera chekuchengetedza simba rekushandisa, rakaburitswa munguva pfupi yapfuura "Nano Express" (Nanoletters). Makambani ese ari maviri ari hunyanzvi mukushambadzira kwemananomaterials, Angerstrong ndiyo yakakura pasi rose nano-granite (NGPS: Nanographeneplatelets) inogadzira. Kungofanana nevatsvakurudzi vanotsanangura mukutsvakurudza kwavo, kune simba ravo pachavo uye kushaya simba mukuchengetedza simba, mabhatiri uye supercapacitors.

Kunyangwe iyo simba density ye lithium ion mabhatiri (120-150 watt / kg) yakakwira zvakanyanya kupfuura supercapacitor (5 watt / kg), bhatiri iri rine simba rakadzika density (1 kW / kg bhatiri) , Enzanisa 10 kW / kg bhatiri). Zvikwata zvakawanda zvekutsvagisa zvakaedza kuwedzera simba rebhatiri relithium-ion, kuvandudza simba reiyo supercapacitor, asi nzvimbo mbiri idzi dzichine matambudziko makuru. Nekuti chimiro chitsva chinopihwa, chinogona kushandiswa kumidziyo yekuchengetedza simba, saka iyi bhatiri yakamisikidzwa pamusoro inobvumira vaongorori kunzvenga matambudziko aya.

Gadzira iyi mudziyo mutsva wekuchengetedza simba, uchidzikisa mukaha pakati pekuita kwe lithium ion bhatiri uye supercapacitor, uye Jiang Bauz akadaro. Zvinotonyanya kukosha, iyi hurongwa hutsva hwekugadzira maturusi ekuchengetedza simba, zvichiita kuti vaongorori vakwanise kuwana yakakwira simba density, asiwo yakakwirira simba density, pasina kubaira mumwe kune mumwe. Iyo yepamusoro-mediated bhatiri electrode ine nzvimbo yakakura yepamusoro, zvekuti iyo yakawanda yakawanda yeion inokurumidza kuvhara, ichiunza kukurumidza kuchaja nguva.

Kwakabva: Kiyi yekushanda kwebhatiri yepamusoro-soro yeAmerican Chemistry, iyo cathode uye anode ine yakakura kwazvo graphene pamusoro. Paunenge uchigadzira mabhatiri, vaongorori vanoisa lithium simbi (muchimiro chezvikamu kana simbi foil) mune anode. Mukutanga kutenderera kutenderera, lithium ionized, nhamba ye lithium ion yakaunzwa kupfuura mubhatiri ye lithium ion.

Kana bhatiri rikashandiswa, maion aya anotamira kune cathode kuburikidza nemvura electrolyte, kupinda pores of kathode kusvika guru graphene pamusoro mucathode. Munguva yekuchaja, yakawanda ye lithium ion flux inokurumidza kutama kubva kune cathode kuenda kune anode. Very hombe electrode pamusoro nzvimbo, zvokuti yakawanda uwandu ions nokukurumidza shuttle, simba guru uye simba density.

Vatsvagiri vakatsanangura kuti pamusoro peiyo porous electrode (panzvimbo peiyo block electrode, senge bhatiri mubhatiri), usapedze nguva inopedza yekuisa maitiro. Munguva iyi, lithium ions inofanira kuiswa pakati pemagetsi, iyo inoumba nguva yakakosha yekuchaja bhatiri. Muchidzidzo ichi, kunyange zvazvo vatsvakurudzi vakashandisa nhamba yakawanda yemhando dzakasiyana-siyana dzegraphite, marudzi akasiyana-siyana egraphene (oxidized, akaderedzwa single-layer uye multi-layer graphene) akagadzirirwa, asi zvinhu izvi uye zvigadziro zvakazoongororwa zvakare kuti zvigadzirise Ichi chigadzirwa.

Kune rimwe divi, vaongorori vanoronga kuenderera mberi nekudzidza hupenyu hwekutenderera kwebhatiri iri. Parizvino, vanoona kuti zvishandiso izvi zvinokwanisa kuchengetedza 95% huwandu mushure memazana zana, kunyangwe mushure memazana maviri ekutenderera, hapasati paine chiratidzo che dendrite. Vatsvagiri vanorongawo kukurukura, nzira dzakasiyana dzekuchengetera lithium zvine chekuita nemashandiro emidziyo.

Isu tinofungidzira kuti kushambadzira kweiyo yepamusoro-mediated bhatiri tekinoroji hakuzove nezvipingamupinyi zvakakura, uye Jiang Bauz akadaro. Kunyangwe iyo yazvino graphene ichitengeswa nemutengo wakakwira, Angerstron Materials Company iri kushingaira kuwedzera simba rekugadzira regraphene. Zvinotarisirwa kuti mumakore 1-3 anotevera, mari yekugadzira graphite ichaderedzwa zvakanyanya.
