Inkqubela entsha kuphando lweebhetri ze-micro-lithium-ion kwiDalian Institute of Chemical Technology

Kutshanje, iqela likaWu Zhongshuai, umphandi wezixhobo ezimacala amabini kunye neqela lophando lwesixhobo samandla seDalian Institute of Chemical Physics, iChinese Academy yeSayensi, kunye neqela likaBao Xinhe, isazi semfundo yaseTshayina yeSayensi, baye baphuhlisa iplani edibeneyo epheleleyo kunye nokudluliselwa kobuninzi be-multi-directional, ukuguquguquka okugqwesileyo kunye nokuzinza okuphezulu kobushushu. Ibhetri encinci ye-lithium-ion. Iziphumo zophando ezinxulumene nazo zapapashwa kwiNanoEnergy.

Ngophuhliso olukhawulezayo lwezixhobo zombane ezinxibayo eziguquguqukayo, ezincinci, kunye nezihlanganisiweyo zombane, kungxamisekile ukuba kuphuhliswe ukusebenza okuphezulu, okukhaphukhaphu, okunxibayo, kunye nolwakhiwo-umsebenzi odityanisiweyo wonikezelo lwamandla olubhetyebhetye kunye nobuchwepheshe babo. Ibhetri yeLithium-ion okwangoku ngowona mthombo wamandla usetyenziswa kakhulu kwaye udumileyo kuluntu, kodwa ineengxaki zokhuseleko ezinje ngobungakanani obukhulu, imilo ezinzileyo, ukuguquguquka okungalunganga, ukuvuza kwe-electrolyte kunye nokutsha, ngoko ke kunzima ukuhlangabezana neemfuno zokuguquguquka kunye ne-miniaturized. izixhobo zombane. isidingo.

Kutshanje, iqela lophando likhokele ekuphuhliseni i-lithium-ion ibhetri encinci ye-lithium-ion yelizwe lonke. I-lithium-ion ibhetri encinci isebenzisa i-nano lithium titanate nanospheres njenge-electrode engalunganga, i-lithium iron phosphate microspheres njenge-electrode efanelekileyo, i-graphene eqhuba kakhulu njenge-non-metallic current collector, kunye ne-ion gel njenge-electrolyte. Inolungelelwaniso olucwangcisiweyo lwe-cross-finger kwaye ayifuni ukusebenzisa i-Diaphragm yendabuko kunye nomqokeleli wangoku wesinyithi.

Ibhetri encinci ye-lithium-ion efunyenweyo inenzuzo yokudluliselwa kobuninzi be-multi-directional, ebonisa ubuninzi bomthamo wamandla we-125.5mWh / cm3, ukusebenza kwezinga eliphezulu; ukuzinza komjikelo we-ultra-long, phantse akukho kuthotywa kwamandla emva kwemijikelo ye-3300; kunye neempawu ezintle zomatshini I-Flexible, isakhiwo se-electrode asiyi konakaliswa kwaye ukusebenza kwe-electrochemical akuyi kutshintsha kakhulu phantsi kokugoba ngokuphindaphindiweyo okanye ukujija.

Ngexesha elifanayo, isixhobo sokugcina amandla esincinci sinokusebenza ngokuzinzileyo kwindawo yokushisa ephezulu ye-100 ° C kwaye inozinzo lomjikelo omde (imijikelezo eyi-1000). Ukongeza, ibhetri ye-lithium-ion inokuqonda ukuzimanya kwemodyuli ngaphandle kwezihlanganisi zentsimbi, kwaye iqonde ukulawulwa okusebenzayo kombane ophumayo kunye nomthamo. Ke ngoko, ibhetri encinci ye-lithium ion inamandla amakhulu ekusebenziseni izixhobo zombane eziguquguqukayo kunye ne-miniaturized.
