Stanford: Takadzikisa huremu hwelithium-ion pantographs ne80 muzana. Iyo simba density inowedzera ne16-26 muzana.
Masayendisiti epaStanford University uye Stanford Linear Accelerator Center (SLAC) vakasarudza kutapudza maseru e-lithium-ion kuti aderedze huremu hwavo nekudaro kuwedzera simba rakachengetwa. Kuti vaite izvi, vakagadzirisa zvakare matanda anotakura kunze: panzvimbo yemashizha akafara emhangura kana aluminium, vakashandisa zvidimbu zvitete zvesimbi, zvichiwedzerwa nehuputi hwepolymer.
Yakakwira simba density muLi-ion pasina yakakwira mari yekudyara
Imwe neimwe Li-ion sero mupumburu unoumbwa necharge-discharge/ discharge layer, electrode, electrolyte, electrode, uye iyezvino muunganidzi muhurongwa ihwohwo. Zvikamu zvekunze isimbi yakagadzirwa nemhangura kana aluminium. Vanobvumira maerekitironi kubuda musero uye kudzokera kwairi.
Masayendisiti kubva kuStanford uye SLAC vakasarudza kutarisa kune vanotora, nekuti uremu hwavo kazhinji makumi akati wandei kubva muzana yehuremu hwese link. Panzvimbo pemapepa emhangura, vakashandisa mafirimu epolymer ane mitsetse yemhangura yakamanikana. Zvakazoitika kuti zvinokwanisika kuderedza uremu hwevateresi kusvika ku80 muzana:
Iyo yakasarudzika cylindrical lithium-ion cell irebesa roll ine akati wandei akaturikidzana. Masayendisiti kubva kuStanford neSLAC akadzikisa maseru anounganidza macheji nekuaitisa - vatori vemazuva ano. Panzvimbo pemapepa emhangura, vakashandisa mapepa epolymer-mhangura akafumiswa nemakemikari asingabatike (c) Yusheng Ye / Stanford University.
Handizvo chete: makemikari emakemikari anogona kuwedzerwa kune polymer inodzivirira kupisa, uye ipapo kupisa kwepasi kwezvinhu kunoperekedzwa nehuremu hwakaderera:
Kupisa kwemhangura foil inoshandiswa mune yekare lithium-ion cell uye muunganidzi akagadzirwa nevatsvagiri veAmerica (c) Yusheng E / Stanford University.
Vatsvagiri vanoti vaunganidzi vakadzokororwa vanogona kuwedzera simba regiravimetric remasero ne16-26 muzana (= 16-26 muzana rinowedzera simba kune imwechete unit yehuremu). Zvinoreva kuti bhatiri rehukuru hwakafanana uye kusimba kwesimba rinogona kuita 20 muzana yakareruka kupfuura ikozvino.
Kuedza kwakaitwa munguva yakapfuura kukwidziridza dura, asi kuvashandura kwakonzera kusatarisira mhedzisiro. Masero akave asina kugadzikana kana kupfuura [inodhura] electrolyte yaidiwa. Musiyano wakagadzirwa nemasainzi kuStanford hauratidzike kuunza matambudziko akadai.
Aya magadzirirwo ari mukutsvaga kwekutanga, saka usatarisira kuti vachasvika pamusika pamberi pa2023. Zvisinei, vanotarisa vachivimbisa.
Inofanira kuwedzerwa kuti Tesla anewo pfungwa inofadza yekuunganidza mutero wezvikamu zvesimbi. Panzvimbo pekushandisa mitsetse yemhangura yakatetepa pamwe nehurefu hwese hwemupumburu uye nekuaburitsa munzvimbo imwe chete (pakati), anobva aaburitsa kunze uchishandisa iyo yakavharwa yekucheka edge. Izvi zvinoita kuti machaji afambe chinhambwe chidiki (kupokana!), Uye mhangura inopa kumwe kuchinjisa kupisa kune kunze:
> Ko masero e4680 mumabhatiri matsva eTesla achatonhodzwa kubva kumusoro uye pasi? Kubva pasi chete?
Izvi zvinogona kukufadza:
