Electric vehicle power lithium battery recycling is forced to be perfected in the imminent system

Umbhali :Iflowpower-UMboneleli weSikhululo saMandla esiphathwayo

uthungelwano logcino lwamandla elizwe lam: Nangona izithuthi zombane zingakhuphi, iibhetri zenkunkuma ziyingozi, ngethemba lokuba abavelisi beemoto basebenzisa ukhuseleko lokusingqongileyo ukuphatha ezi bhetri zenkunkuma. Kungekudala, abasebenzisi be-intanethi bathathe inxaxheba kumbane we-lithium-ion ibhetri yemoto e-Weibo ukubangela ingxoxo yesihloko songcoliseko. Ngokuduma kwezithuthi zombane, ukubuyiswa kwebhetri kunye nokusetyenziswa kwakhona kuba sisihloko sokhathalelo lwabasebenzisi abaninzi be-intanethi.

UNetizen uSimonRock uthe: Ukucoca kunye nokukhuselwa kwendalo kuyindlela eqhelekileyo yophuhliso lwezithuthi ezizayo, kwaye izithuthi zombane zinokufikelela kwi-zero ekhutshwayo, eluncedo kakhulu ekukhuselweni kwendalo, kodwa ukhetho lwebhetri kunye nonyango olungenabungozi kamva lubaluleke kakhulu, kufuneka luthintele entsha. ukungcoliseka kwendalo. Iingcali zoshishino zabonisa ukuba njengenxalenye ebalulekileyo yetsheyini yoshishino lwezithuthi zamandla amatsha, ukuphuhliswa kweebhetri ze-lithium-ion eziguquguqukayo ekuphuculeni ukusebenza, ukuphononongwa kokuhlaziywa kunye nokusetyenziswa kwakhona kweemodeli yinto engafanelekanga. Ukuhlaziywa kwebhetri kunyanzeliswa ngama-phyngers.

Ungcoliseko lwebhetri alungomngxuma. Unjingalwazi Beijing Institute of Technology wathi: 1 20 grams ibhetri mobile phone angangcolisa amanzi 3 amadama okuqubha eqhelekileyo, ukuba ilahliwe emhlabeni, ungenza 1 square kilometers Ungcoliseko iminyaka engaphezu kwama-50. Khawucinge, ukuba i-200 kg yemoto yombane yamandla e-lithium-ion ibhetri ilahlwe kwindawo yendalo? Inani elikhulu leentsimbi ezinzima kunye neekhemikhali zingena kwindalo, eziya kubangela ukungcoliseka okukhulu kokusingqongileyo.

Ngokutsho kwentatheli, kukho ngoku, uphando olubalulekileyo lwamandla e-lithium-ion iibhetri zasekhaya ngokwemigaqo yokuphucula ukusebenza, kwaye ingqalelo yokudibanisa i-recycling ngokucacileyo ayanelanga. Ngeli nqanaba, kukho uluhlu olubanzi lweebhetri ze-lithium-ion kwiimoto zombane. Iibhetri ezinjalo aziqulathanga i-mercury, i-cadmium, i-lead oriented heavy metal elements, kodwa izixhobo zabo ze-electrode ezintle nezimbi, izisombululo ze-electrolyte kunye nezinye izinto zinempembelelo enkulu kakhulu.

Iziko lophando lwelizwe lam lobuchwepheshe bemoto liqikelela ukuba ngo-2015, iibhetri zasekhaya ze-lithium-ion zaqokelela inani elimalunga neetoni ezingama-20,000. Ngo-2020, ibhetri yelizwe lam yombane i-lithium-ion ibhetri eqokelelweyo ye-scrap volume iya kufikelela kwi-120,000 ukuya kwi-170,000 yeetoni. isikali.

Ukuba akukho sixokelelwano sisemgangathweni sokurisayikilishwa kwebhetri, ezi bhetri ziyakwenzeka ngokungathandabuzekiyo kokusingqongileyo. Ixabiso eliluncedo lidla ngokusetyenziswa, kwaye ubomi bebhetri ye-lithium-ion kwimo engqongileyo jikelele malunga neminyaka engama-20, kodwa xa amandla ebhetri athotywa ukuya kuma-80% omthamo webhetri ukuya kwi-80% yomthamo wokuqala, ukuhlaziya i-mileout. yesithuthi sombane Ngokucacileyo kuncitshiswe, ngoko elona xesha lokusetyenziswa limalunga ne-3 ukuya kwi-8 iminyaka. Nangona kunjalo, ezi bhetri zisetyenzisiweyo zisenexabiso.

Kwiinkqubo zokugcina amandla, ezi bhetri zisenexabiso elikhulu lokusetyenziswa, ukuseka ukusetyenziswa kwenyathelo lebhetri ye-lithium-ion kunye nenkqubo yolawulo lokuhlaziya mhlawumbi ukhetho olunokwenzeka. U-Chen Jinchen, uProfesa, iYunivesithi yaseTsinghua, ibhetri ingaphantsi kwe-80%, ingaqhubeka isetyenziselwa ukugcinwa kwegridi yamandla, okanye njengomthombo wamandla wezithuthi eziphantsi kwesantya ezifana nombane ngokubhekiselele, kukho nexabiso lesibini lokusetyenziswa. I-ladder isebenzisa ixabiso le-lithium-ion ibhetri yamandla ukufezekisa umdlalo opheleleyo, ngokunciphisa iindleko zebhetri kunye nokukhuthaza isithuthi sombane esithandwayo.

Ukuba ibhetri yenkunkuma iphinda isetyenziswe, izinto ezifana nobhedu, i-aluminiyam, i-nickel kunye ne-cobalt ebhetri ingasetyenziselwa ukusebenzisa iteknoloji yenkqubo ye-metallurgical. Ayinako nje ukuthintela isoyikiso esinokubakho semo engqongileyo, kodwa ikwalawula ngempumelelo iindleko zebhetri. Ukuthatha ibhetri ye-lithium-ion ye-nickel hydride, umxholo we-nickel wenkunkuma ye-nickel i-hydrogen yamandla e-lithium ion ibhetri i-30% ukuya kwi-50%, umxholo we-cobalt ngu-2% ukuya kwi-5%, umxholo wehlabathi onqabileyo ngu-5% ukuya kwi-10% , enokubuyiselwa okuphezulu.

Ixabiso lezoQoqosho. U-Yu Navy, uMlawuli woPhuhliso lweSicwangciso se-Bond Circular Technology Co., Ltd.

, uxelele iintatheli ukuba emva kokubuyiswa kweebhetri zenkunkuma, emva kokuqhaqha, ukuphulwa, i-alkali, ukucwiliswa kwe-asidi, i-induction kunye namanye amanyathelo, kwaye ekugqibeleni kuncitshiswe imveliso yesiphumo Imveliso ye-original ye-industrial-grade efunekayo kwimveliso yebhetri, ukuthengiswa kumenzi webhetri. Sifumana iibhetri zenkunkuma ngexabiso eliphantsi. Ukongeza, sithatha inxaxheba ekusetyenzisweni ngokutsha kwenkunkuma.

Wathi uYu Haijun. Inkqubo yokurisayikilisha kufuneka iphuculwe. Okwangoku, izithuthi zombane zikwinqanaba lokuthengisa, kwaye akukho luhlu olubanzi lwezicelo.

Ibhetri ye-lithium-ion yemoto yombane ayizange ibe nomlinganiselo omkhulu we-scrap, ngoko ke ilizwe lam alizange limisele inkqubo yokuphinda isetyenziswe ibhetri ye-lithium-ion. Nangona kunjalo, ezinye izixeko eziphuhlayo ezikhawulezayo zenze uphononongo lovavanyo, i-Shenzhen Energy Saving and Energy Demonstration Promotion ye-Ofisi yeQela eliKhokelayo, umlawuli weofisi, uxelele iintatheli ukuba i-Shenzhen iseke ukusetyenziswa kwebhetri ye-lithium-ion yemoto kunye nenkqubo yokuphinda isetyenziswe. Yonke intengiso yi-yuan engama-600, kwaye urhulumente uthatha i-yuan engama-300, esetyenziselwa ukubuyisela amandla ebhetri ye-lithium-ion, ekuqaleni ukuseka indlela yokuhlaziya ibhetri.

Ngokutsho kweentatheli, okwangoku kukho inani elithile le-nickel-hydrogen, iibhetri ze-lithium-ion kunye neenkampani zokuvuselela i-cobalt-nickel-nickel, kunye nesiseko sokuhlaziywa kunye nokuhlaziywa konyango lweebhetri ze-lithium-ion zesithuthi. Uthungelwano lwenkonzo yokurisayikilisha luya lusanda ngokuthe ngcembe. Ngokweengcali zoshishino, iibhetri ze-lithium-ion zemoto kunye ne-electronics zabathengi, i-nickel-cadmium, kunye neebhetri ze-lithium-ion ziyafana, kubalulekile ukukhupha isinyithi esixabisekileyo njenge-nickel, i-cobalt, izinto ezinqabileyo zomhlaba, kwaye ngoku Ngokusisiseko zihambelana nokubuyisela. iteknoloji yokucubungula.
