Ngomhla we-19 kaNovemba, i-2nd Technology and Industry Development Forum yabanjwa eKunshan. Kumsitho wokuvula iqonga, iQingtao (Kunshan) Energy Development Co., Ltd. yamema iindwendwe ukuba zityelele umgca wokuqala wokuvelisa ibhetri yelithium eTshayina. Kuxelwe ukuba lo mgca wemveliso unokuvelisa iibhetri ze-10,000 eziqinileyo ngosuku, kwaye ubuninzi bamandla beebhetri bunokufikelela ngaphezu kwe-400Wh. Okwangoku, iimveliso ziya kusetyenziswa ikakhulu kwidijithali ephezulu kunye nezinye iindawo, kwaye kulindeleke ukuba zingene kwintsimi ngo-2020 ukubonelela ngeebhetri kwiinkampani zeemoto. Ngokukhawuleza nje ukuba ezi ndaba zivele, kwaphantse kwavakala kwishishini.

Iibhetri ze-lithium zamandla zifana nentliziyo yeenqwelo zombane, kwaye ixabiso libuye lithathe ngaphezu kwesiqingatha semoto yonke. Ke ngoko, itekhnoloji yebhetri ibaluleke kakhulu kuphuhliso lweshishini elitsha lamandla. Ukuba i-bottleneck yangoku yomthamo webhetri ye-lithium esekelwe kumanzi ayinakuphulwa, yonke Ishishini linokuthi liwele kwimeko enzima kakhulu. Kwixesha elizayo, kungekhona kuphela iimoto zentsapho, kodwa kunye neenqwelo zombane kufuneka zisebenzise amandla ombane, kwaye iimfuno zeebhetri ziya kuba ziphezulu. Ke ngoko, iibhetri zombuso oqinileyo ezineplastikhi ephezulu ziye zaba lukhokelo lwemizamo yeenkampani ezininzi, kubandakanywa iinkampani zeemoto ezaziwayo kumazwe ngamazwe ezifana neToyota, BMW, Mercedes-Benz, neVolkswagen, kunye neenkampani ezinkulu ezixhaswa ngemali liSebe leMicimbi yezoQoqosho. IJapan, sele iqalile ukusebenza kule ndawo.

Kulo mboniso womgca wemveliso weKunshan Qingtao Inkampani, abantu babone oku: Emva kokuba ipakethe yebhetri enobunzima bozipho lweminwe yasikwa ngesikere, ayizange igqabhuke nje kuphela, kodwa ide inikwe amandla ngokuqhelekileyo. Ukongeza, nokuba ibigobile amashumi amawaka amaxesha, amandla ebhetri awazange abole ngaphezu kwe-5%, kwaye ibhetri ayizange itshise okanye iqhume emva kwe-acupuncture. Ngapha koko, iibhetri ze-lithium eziqinileyo zineenzuzo ezininzi. Ngenxa yokuba i-electrolytes eqinile ayinakutsha, i-non-corrosive, i-non-volative, kunye ne-non-leakge, ayiyi kubangela iziganeko zokutsha ezizenzekelayo kwisithuthi, esiphucula kakhulu ukhuseleko. Inene luhlobo lwemathiriyeli efanelekileyo yebhetri yezithuthi zombane.

Okwangoku, izithuthi zombane eziqhelekileyo zisetyenziswa ngokuqhelekileyo, ngokwenene, kukho iziphene ezithile, kuba kungakhathaliseki ukuba kwisakhiwo sekhemikhali okanye isakhiwo sebhetri, i-ternary lithium ilula kakhulu ukuvelisa ukushisa. Ukuba uxinzelelo alukwazi ukuhanjiswa ngexesha, kukho umngcipheko wokuqhuma kwebhetri, kwaye uninzi lweziganeko zokutsha ezizenzekelayo zezithuthi zombane ezenzeke kulo nyaka nazo zibangelwa yile nto. Kwaye ngokwemiqathango yokunyamezela, ubuninzi bamandla obunye beebhetri ze-lithium ze-ternary okwangoku zijongene ne-bottleneck, kwaye kunzima ukuyiqhekeza. Ukuba ufuna ukunyusa ubuninzi bamandla, unokwandisa kuphela umxholo we-nickel okanye ungeze i-CA, kodwa ukuzinza kwe-thermal ye-nickel ephezulu kubi kakhulu, kwaye kulungele ukuphendulwa kobundlobongela. Ke ngoko, okwangoku, kuphela urhwebo olunokwenziwa phakathi komthamo webhetri kunye nokhuseleko.

Nkqu Toyota, nto leyo intle kakhulu kwezobuchwephesha kunye nophando lwezobuchwepheshe kunye nophuhliso, wathi iibhetri-slid-state akayi kuba nako ukufikelela imveliso ngobuninzi 2030. Kuyabonakala ukuba kusekho ezinye iingxaki kuphando kunye nophuhliso eqinileyo- iibhetri zikarhulumente. Enyanisweni, ekubeni iibhetri eziqinileyo azifuni ukungena kwamanzi kwaye zifuna kuphela i-electrolyte eqinileyo ukwahlula iipleyiti ezintle nezimbi, ukhetho lwezixhobo zetsimbi luba lubaluleke kakhulu. Owona mngeni mkhulu kobu buchwepheshe kukuba ukuhanjiswa kwe-electrolyte eyomeleleyo kuphantsi kunolwelo lwe-electrolyte, nto leyo ekhokelela ekusebenzeni okuphantsi komgangatho webhetri eqinileyo yangoku kunye nokuxhathisa okukhulu kwangaphakathi. Ke ngoko, ibhetri yemeko eqinileyo okwexeshana ayinakuhlangabezana neemfuno zokutshaja ngokukhawuleza. Funa. Nangona kunjalo, i-conductivity yombane inobudlelwane obukhulu kakhulu kunye nobushushu, ngoko ke ukusebenza kwiqondo lokushisa eliphezulu kuya kwenza ibhetri isebenze ngcono. Ukongeza, i-conductivity yebhetri kufuneka igcinwe kwinqanaba eliqhelekileyo, kwaye ikhoyo ngoku iphezulu okanye iphantsi kakhulu inokubangela ezinye iingxaki.

Namhlanje, uphando kunye nophuhliso lwetekhnoloji yeebhetri ze-lithium ze-ternary ziinkampani ezikhokelwa yiPanasonic kunye neCATL sele zisekwe kakuhle. Nokuba iibhetri ze-lithium eziqinileyo ziphuhliswa ngexesha elifutshane, kunzima ukufezekisa imveliso yobuninzi. Emva kwayo yonke loo nto, xa itekhnoloji entsha isiya kwihlabathi, ihlala iyimfuneko ukuba inkampani ibe nomthamo wemveliso ohambelanayo kunye nomthamo wemveliso ukuze kuphunyezwe ukukhuthazwa okukhulu kunye nokusetyenziswa. Nangona iibhetri zelithium zangoku zisajongene neengxaki ezininzi kwaye azinanzuzo ingako kuxinzelelo lwamandla okwangoku, zinokhuseleko oluphezulu kakhulu. Ukuba izixhobo ezifanelekileyo zetsimbi zingaphuhliswa, mhlawumbi ibhetri ye-lithium yonke Ishishini liya kungenisa ukuphumelela okutsha. Yile nto sifuna ukuyibona. Ngapha koko, uphando olungagungqiyo ngumoya wokwenyani wophando lwesayensi. Umlinganiselo woxinaniso lwamandla ubhekisa kumthamo webhetri ngeyunithi yobunzima. I-Cylindrical monomer ibalwa ngokungqinelana ne-18650 yasekhaya yangoku (1.75AH), umlinganiselo wobuninzi bamandla unokufikelela kwi-215WH / Kg, kwaye i-square monomer ibalwa ngokutsho kwe-50AH kunye nomlinganiselo wobuninzi bamandla unokufikelela kwi-205WH / Kg. Izinga lokuhlelwa kwenkqubo lijikeleze i-60% kwi-18650, kwaye isikwere sijikeleze i-70%. (Inqanaba lokuhlelwa kwenkqubo linokucingelwa ngokubeka iham ebhokisini. Umsantsa phakathi kwee-square hams mncinci, ngoko ke izinga lokuhlelwa kwenkqubo liphezulu.)

Ngale ndlela, umlinganiselo wamandla we-18650 ye-bettery pack pack system malunga ne-129WH / Kg, kunye nomlinganiselo wamandla we-square battery pack system malunga ne-143WH / Kg. Xa ubungakanani bamandla obuninzi be-18650 kunye neeseli zesikwere zifikelela kwikamva elifanayo, iipakethi zebhetri ze-lithium ezinezinga eliphezulu lokuhlanganisa ziya kuba neenzuzo ezicacileyo.

Ukumakishwa

Ireyithi yokutshaja/yokukhupha=ukutshaja/ukukhupha amandla akhoyo/okulinganiswayo, okukhona umlinganiselo ophezulu, kokukhona ukukhawuleza kwesantya sokutshaja esixhaswa yibhetri. Ibhetri yamandla ethe tyaba eveliswe ekhaya i-18650 ijikeleze i-1C, kwaye isikwere sinokufikelela malunga ne-1.5-2C (ngolawulo olululo lwe-thermal), kwaye kusekho umgama ukusuka kwithagethi yepolisi ye-3C. Nangona kunjalo, kunokwenzeka ngokupheleleyo ukuba inkqubo yokwenziwa kwesikwere iya kuba ngakumbi kwaye igqibelele ngakumbi ukufezekisa ekujoliswe kuko okumiselweyo kwe-3C.
