Lithium-ion mabhatiri tekinoroji inenge yakajairika ine dhizaini yakakomba: dzimwe nguva dzinobata moto.
Vhidhiyo yevashandi nevafambi vari mundege yeJetBlue vachidira mvura mumabhegi avo inova muenzaniso wazvino wekunetsekana pamusoro pemabhatiri, ayo ave kuwanikwa munenge mumudziyo wese unoda simba rinotakurika.Mumakore gumi apfuura, kwave nekuwedzera kwemisoro pamusoro pe lithium-ion bhatiri moto unokonzerwa nemabhasikoro emagetsi, mota dzemagetsi uye malaptop pandege dzevatakuri.
Kuwedzera kunetseka kwevanhu kwakakurudzira vatsvakurudzi pasi rose kuti vashande kuvandudza kuchengeteka uye hupenyu hurefu hwemabhatiri e-lithium-ion.
Battery innovation yanga ichiputika mumakore achangopfuura, nevatsvakurudzi vachigadzira mabhatiri ehurumende kuburikidza nekutsiva magetsi emagetsi emagetsi mumabhatiri e-lithium-ion ane zvinhu zvakagadzikana zvakasimba zve electrolyte zvakadai semagetsi asingabatiki, magirazi emagetsi uye mapolima akasimba.
Tsvagiridzo yakabudiswa svondo rapfuura mujenari Nature inoratidzira nzira nyowani yekuchengetedza kudzivirira kuumbwa kwe lithium "dendrites," iyo inoumba kana lithium-ion mabhatiri achipisa nekuda kwekuwedzeredza kana kukuvadza chimiro che dendritic.MaDendrites anogona kupfupisa mabhatiri uye kukonzera moto unoputika.
"Chidzidzo chega chega chinotipa chivimbo chakanyanya kuti tinokwanisa kugadzirisa kuchengeteka uye matambudziko akasiyana-siyana emotokari dzemagetsi," akadaro Chongsheng Wang, purofesa wemakemikari uye biomolecular engineering paYunivhesiti yeMaryland uye munyori anotungamirira wekudzidza.
Kubudirira kwaWang inhanho inokosha yekuvandudza kuchengetedzwa kwemabhatiri e-lithium-ion, akadaro Yuzhang Li, mubatsiri wepurofesa wemakemikari engineering kuUCLA akanga asina kubatanidzwa muchidzidzo.
Lee ari kushanda ari ega hunyanzvi hwake, kugadzira chizvarwa chinotevera lithium simbi bhatiri iyo inogona kuchengeta ka10 simba rakawanda kupfuura graphite electrode zvikamu mumabhatiri e lithium-ion.
Kana zvasvika pakuchengetedzeka kwemotokari yemagetsi, Lee akati mabhatiri e-lithium-ion haana njodzi kana akajairika sekufunga kunoita veruzhinji, uye kunzwisisa lithium-ion bhatiri rekuchengetedza mapuroteni kwakakosha.
"Zvese mota dzemagetsi uye dzakajairwa mota dzine njodzi dzinowanikwa," akadaro."Asi ndinofunga mota dzemagetsi dzakachengetedzeka nekuti hausi kugara pamarita emvura inopisa."
Lee akawedzera kuti zvakakosha kutora matanho ekudzivirira pamusoro pekuwedzeredza kana mushure menjodzi yemotokari yemagetsi.
Vatsvagiri vanodzidza nezve lithium-ion bhatiri moto kusangano risingabatsiri reFire Research Foundation vakawana kuti moto mumotokari dzemagetsi unofananidzwa nemoto mumotokari dzechinyakare dzine peturu, asi moto mumotokari dzemagetsi unogara kwenguva refu, unoda mvura yakawanda kudzima uye yakawanda. zvinogona kupfuta.zvakare.maawa akawanda mushure mokunge murazvo wanyangarika nekuda kwesimba rinosara mubhatiri.
Victoria Hutchison, maneja mukuru wenheyo yekutsvaga chirongwa, akati mota dzemagetsi dzinoisa njodzi yakasarudzika kune vanodzima moto, vanotanga kupindura uye vatyairi nekuda kwemabhatiri avo e-lithium-ion.Asi hazvireve hazvo kuti vanhu vanofanirwa kuvatya, akawedzera.
"Tichiri kuedza kunzwisisa kuti moto wemotokari dzemagetsi chii uye kuti tingadzirwisa sei," akadaro Hutcheson.“Iyo nzira yekudzidza.Tave nemotokari dzeinjini dzinopisa mukati kwenguva refu ikozvino, hazvizivikanwe, asi isu tinongofanira kudzidza maitiro ekuita nezviitiko izvi nemazvo. "
Kunetsekana nezvemoto wemotokari yemagetsi kunogonawo kukwidza mitengo yeinishuwarenzi, akadaro Martti Simojoki, nyanzvi yekudzivirira kurasikirwa kuInternational Union yeMarine Inishuwarenzi.Vati kuita inishuwarenzi yemotokari dzemagetsi sekutakura pari zvino imwe yemitsara isinganakidze yebhizinesi kune veinishuwarenzi, izvo zvinogona kuwedzera mutengo weinishuwarenzi kune avo vari kutsvaga kutakura mota dzemagetsi nekuda kwengozi inofungidzirwa yemoto.
Asi ongororo yakaitwa neInternational Union of Marine Insurance, boka risingaite purofiti inomiririra makambani einishuwarenzi, yakaona kuti mota dzemagetsi hadzina njodzi kana njodzi kupfuura mota dzemazuva ose.Kutaura zvazviri, hazvina kusimbiswa kuti moto wepamusoro wemoto kubva kuDutch coast ino zhizha wakakonzerwa nemotokari yemagetsi, pasinei nemusoro wenyaya unoratidza zvimwe, Simojoki akati.
"Ndinofunga kuti vanhu vanozeza kuisa njodzi," akadaro."Kana njodzi yakakwira, mutengo unokwira.Pakupera kwezuva, mutengi wekupedzisira anobhadhara. "
Kururamisa (Nov. 7, 2023, 9:07 am ET): Shanduro yakapfuura yechinyorwa chino yakanganisa zita remunyori anotungamira wechidzidzo.Iye ndiWang Chunsheng, kwete Chunsheng.
