Ibhetri ye-lithium luhlobo lwebhetri esebenzisa isinyithi se-lithium okanye i-lithium alloy njengento engafanelekanga ye-electrode kunye nesisombululo se-electrolyte esingenayo. Iibhetri zeLithium zisetyenziswa kakhulu kwiimveliso zedijithali kwintsimi yendabuko, kwaye zisetyenziswa kakhulu kwintsimi yeebhetri zamandla kunye nokugcinwa kwamandla kwiindawo ezivelayo.
I-China inezixhobo ezininzi ze-lithium kunye nekhonkco loshishino lwebhetri ye-lithium epheleleyo, kunye nesiseko esikhulu seetalente, okwenza i-China ibe yeyona ndawo inomtsalane kuphuhliso lweebhetri ze-lithium kunye noshishino lwezixhobo, kwaye iye yaba yi-lithium enkulu yehlabathi. Izinto zebhetri kunye nesiseko sokuvelisa ibhetri. Ukunyuka komjelo we-lithium ibhetri ye-lithium chain iquka i-cobalt, i-manganese, i-nickel ore, i-lithium ore, kunye ne-graphite ore. Kuluhlu lweshishini lokuvelisa ibhetri ye-lithium, eyona nxalenye ingundoqo yebhetri ingundoqo. Emva kokuba i-core yebhetri ihlanganiswe, i-wiring harness kunye nefilimu ye-PVC idibaniswe ukwenza imodyuli yebhetri, kwaye emva koko i-wire harness connector kunye nebhodi yesekethe ye-BMS yongezwa ukwenza imveliso yebhetri yamandla.
Uhlalutyo oluphezulu lwekhonkco lemizi-mveliso
Ukunyuka kwebhetri ye-lithium kukumbiwa kwemigodi kunye nokucutshungulwa kwemithombo yezinto ezibonakalayo, ngokukodwa izixhobo ze-lithium, izixhobo ze-cobalt kunye negraphite. Ukusetyenziswa kwezinto ezintathu eziluhlaza zezithuthi zombane: i-lithium carbonate, i-cobalt kunye negraphite. Kuyaqondwa ukuba i-lithium resource reserves ityebile kakhulu, kwaye okwangoku i-60% yemithombo ye-lithium ayizange iphononongwe kwaye iphuhliswe, kodwa ukuhanjiswa kwemigodi ye-lithium kugxininiswe kakhulu, isasazwa kwindawo "ye-lithium triangle" yaseMzantsi Melika. , eOstreliya naseTshayina.
Okwangoku, oovimba behlabathi bokomba bamalunga ne-7 yezigidi zeetoni, kwaye ukuhanjiswa kugxininiswe. Oovimba baseCongo (DRC), eOstreliya naseCuba bathatha ama-70% ovimba behlabathi, ngakumbi oovimba baseCongo abazizigidi ezi-3.4 zeetoni, ezibalelwa ngaphezu kwama-50% ehlabathi. .
Uhlalutyo oluphakathi kwishishini lebhetri ye-lithium
Umbindi woshishino lwebhetri ye-lithium ikakhulu ubandakanya izinto ezahlukeneyo ezilungileyo nezingalunganga, kunye ne-electrolytes, iithebhu, i-diaphragms kunye neebhetri.
Phakathi kwabo, i-lithium ibhetri ye-electrolyte ngumthwali wokuqhuba i-lithium ion kwibhetri ye-lithium ion, kwaye idlala indima ebalulekileyo ekusebenzeni nasekukhuseleni ibhetri ye-lithium. Umgaqo osebenzayo webhetri ye-lithium-ion nayo yinkqubo yokutshaja kunye nokukhupha, oko kukuthi, i-ion ye-lithium ivaliwe phakathi kwe-electrode efanelekileyo kunye ne-negative, kwaye i-electrolyte iphakathi kokuhamba kwe-lithium ion. Umsebenzi oyintloko we-diaphragm kukwahlula i-electrode efanelekileyo kunye nembi yebhetri, ukukhusela izibonda ezimbini ukuba zidibanise kunye ne-short-circuit, kwaye zibe nomsebenzi wokudlula i-ion electrolyte.
Uhlalutyo olusezantsi lwekhonkco loshishino lwebhetri ye-lithium
Ngo-2018, imveliso yemakethe yebhetri ye-lithium-ion yaseChina inyuke nge-26.71% unyaka nonyaka ukuya kwi-102.00GWh. Imveliso ye-China yehlabathi ibalwa kwi-54.03%, kwaye iye yaba ngumvelisi omkhulu webhetri we-lithium-ion wehlabathi. Iinkampani ezimele ibhetri yeLithium zezi: ixesha le-Ningde, i-BYD, i-Waterma, i-Guoxuan Hi-Tech njalo njalo.
Ukusuka kwimakethi yesicelo esezantsi yeebhetri ze-lithium-ion e-China, ibhetri yamandla ngo-2018 iqhutywe kuphuhliso olukhawulezayo lweshishini elitsha lemoto yamandla. Isiphumo sinyuke nge-46.07% unyaka nonyaka ukuya kwi-65GWh, eyaba lelona candelo likhulu; imarike yebhetri yedijithali ye-3C ngo-2018 Ukukhula kwakuzinza, kwaye imveliso yehla nge-2.15% ngonyaka ukuya kwi-31.8GWh, kwaye izinga lokukhula liyehla. Nangona kunjalo, intsimi yebhetri yedijithali ephezulu emele iibhetri eziguquguqukayo, iibhetri zedijithali eziphezulu kunye neepakethi ezithambileyo zedijithali eziphezulu zixhomekeke kwizixhobo ezinxitywayo, i-drones, kunye nobukrelekrele bokugqibela. Iqhutywa ngamacandelo emarike afana neefowuni eziphathwayo, iye yaba yinxalenye yokukhula okuphezulu kwemarike yebhetri yedijithali ye-3C; kwi-2018, i-China yokugcina amandla e-lithium-ion iibhetri zonyuka kancinci nge-48.57% ukuya kwi-5.2GWh.
Ibhetri yaMandla
Kwiminyaka yakutshanje, ibhetri ye-lithium-ion yase-China iphuhliswe ngokukhawuleza, ngenxa yenkxaso eqinile yemigaqo-nkqubo yelizwe yoshishino lwemoto entsha yamandla. Ngo-2018, imveliso yezithuthi zamandla amatsha e-China yanda ngo-50.62% ngonyaka ukuya kwi-1.22 yezigidi zeeyunithi, kwaye imveliso yayiyi-14.66 ngamaxesha ka-2014. Iqhutywa kuphuhliso lwemarike yemoto yamandla amatsha, imarike yebhetri yamandla yaseChina igcinwe ngokukhawuleza. ukukhula kwi-2017-2018. Ngokwezibalo zophando, imveliso yemakethe yebhetri yamandla yaseTshayina ngo-2018 inyuke nge-46.07% unyaka nonyaka ukuya kwi-65GWh.
Ngokuphunyezwa ngokusesikweni kwenkqubo entsha yamanqaku ezithuthi zamandla, iinkampani zezithuthi zamafutha zemveli ziya kwandisa ukumiswa kwezithuthi zamandla amatsha, kwaye iinkampani zangaphandle ezifana neVolkswagen kunye neDaimler ziya kudityaniswa zakha izithuthi zamandla amatsha eTshayina. Imfuno yemakethe yebhetri yamandla yaseTshayina iya kuba Ukugcina imeko yokukhula ngokukhawuleza, kulindeleke ukuba i-CAGR yokuveliswa kwebhetri yamandla iya kufikelela kwi-56.32% kwiminyaka emibini ezayo, kwaye imveliso yebhetri yamandla iya kudlula i-158.8GWh ngo-2020.
Imakethi yebhetri ye-lithium-ion yaseTshayina igcine ukukhula okukhawulezayo, ikakhulu iqhutywa kukukhula okukhawulezayo kwemarike yebhetri yamandla. Ngo-2018, amashishini amahlanu aphezulu kwimakethi yebhetri yamandla yaseTshayina abalelwa kwi-71.60% yexabiso lemveliso, kwaye ugxininiso lwentengiso luye lwaphuculwa ngakumbi.
Ibhetri yamandla exesha elizayo yinjini enkulu yokukhula kwintsimi yeebhetri ze-lithium-ion. Umkhwa wayo wokuxinana kwamandla aphezulu kunye nokhuseleko oluphezulu luye lwamiselwa. Iibhetri zamandla kunye ne-high-end digital lithium-ion iibhetri ziya kuba ngamanqaku okukhula okuphambili kwimarike yebhetri ye-lithium-ion, kunye neebhetri ze-lithium ngaphakathi kwe-6μm. I-foil ye-Copper iya kuba yinto ephambili yezinto ezibonakalayo kwiibhetri ze-lithium-ion kwaye iya kuba yingqwalasela yamashishini aqhelekileyo.
3C ibhetri
Ngo-2018, imveliso yebhetri yedijithali yaseTshayina yehle nge-2.15% unyaka nonyaka ukuya kwi-31.8GWh. I-GGII ilindele ukuba ibhetri yedijithali iCAGR iya kuba yi-7.87% kwiminyaka emibini ezayo. Kuqikelelwa ukuba imveliso yebhetri yedijithali yaseTshayina iya kufikelela kwi-34GWh ngo-2019.
