Inqubekelaphambili entsha ocwaningweni lwamabhethri e-micro-lithium-ion e-Dalian Institute of Chemical Technology

Muva nje, ithimba lika-Wu Zhongshuai, umcwaningi weqembu lokucwaninga lezinto ezinezici ezimbili namandla e-Dalian Institute of Chemical Physics, i-Chinese Academy of Sciences, kanye nethimba lika-Bao Xinhe, isazi sezemfundo sase-China Academy of Sciences, baye bahlakulela i-planar ehlanganisiwe ephelele ngokudluliswa kwenqwaba ye-multi-directional, ukuguquguquka okuhle kakhulu kanye nokuzinza okuphezulu kwezinga lokushisa. Ibhethri elincane le-lithium-ion lesimo esiqinile. Imiphumela yocwaningo ehlobene yashicilelwa ku-NanoEnergy.

Ngokuthuthuka okusheshayo kwezinto eziguquguqukayo ezigqokekayo, ezenziwe nge-miniaturized, nezididiyelwe ze-elekthronikhi, kuyaphuthuma ukuthuthukisa ukusebenza okuphezulu, okungasindi, okugqokekayo, kanye nesakhiwo-umsebenzi wamandla ahlanganisiwe avumelana nezimo kanye nobuchwepheshe bazo. Ibhethri ye-lithium-ion njengamanje iwumthombo wamandla osetshenziswa kakhulu futhi othandwa kakhulu emphakathini, kodwa inezinkinga zokuphepha njengosayizi omkhulu, ukuma okungaguquki, ukuguquguquka okungekuhle, ukuvuza kwe-electrolyte nokuvutha, ngakho-ke kunzima ukuhlangabezana nezidingo zokuguquguquka kanye ne-miniaturized. izinto zikagesi. isidingo.

Muva nje, ithimba locwaningo lihole ekwakhiweni kwebhethri elincane le-lithium-ion elididiyelwe leplanethi elihlanganisiwe. Ibhethri elincane le-lithium-ion lisebenzisa i-nano lithium titanate nanospheres njenge-electrode engeyinhle, i-lithium iron phosphate microspheres njenge-electrode ephozithivu, i-graphene eqhuba kakhulu njengomqoqi wamanje ongeyona eyensimbi, kanye nejeli ye-ion njenge-electrolyte. Inokwakheka kwe-planar cross-finger futhi ayidingi ukusebenzisa i-Diafhragm evamile kanye nesiqoqi samanje sensimbi.

Ibhethri elincane le-lithium-ion elitholiwe linenzuzo yokudluliswa kwenqwaba yezindlela eziningi, ekhombisa umthamo omkhulu wamandla wevolumu engu-125.5mWh/cm3, ukusebenza kwesilinganiso esihle kakhulu; Ukuqina komjikelezo omude, cishe akukho ukuwohloka komthamo ngemuva kwemijikelezo engama-3300; kanye nezakhiwo ezinhle zemishini Iyaguquguquka, isakhiwo se-electrode ngeke sonakaliswe futhi ukusebenza kwe-electrochemical ngeke kushintshe kakhulu ngaphansi kokugoba okuphindaphindiwe noma ukusonteka.

Ngesikhathi esifanayo, idivayisi encane yokugcina amandla ingasebenza ngokuzinza endaweni yokushisa ephezulu engu-100°C futhi inozinzo lomjikelezo omude (imijikelezo engu-1000). Ngaphezu kwalokho, ibhethri ye-lithium-ion ingakwazi ukubona ukuzihlanganisa kwe-modular ngaphandle kwezixhumi zensimbi, futhi ibone ukulawulwa okusebenzayo kwamandla okukhipha amandla namandla. Ngakho-ke, ibhethri elincane le-lithium ion linamandla amakhulu ekusetshenzisweni kwezinto zikagesi eziguquguqukayo nezincane.
