Chengetedzo yekutarisa indasitiri ndiyo kukura kwehupfumi hweChina, mitemo yenyika kusimudzira indasitiri yekubuda kwezuva, ndiko kukura kwesimba idzva, kuchengetedzwa kwezvakatipoteredza, yakakosha indasitiri yehurongwa, asiwo kuvakwa kwekuchengetedzwa kwemagariro ekudzivirira uye kudzora hurongwa. Zvinoenderana ne "China's security industry" 13 Five "development plan" kuronga kunoratidza kuti panosvika 2020 China indasitiri yekutarisa kuchengetedza ichasvika anopfuura bhiriyoni makumi mashanu yuan. Parizvino, iyo indasitiri yekuchengetedzwa kwekuchengetedza indasitiri yelithium bhatiri yave kuzivikanwa nemabhizinesi mazhinji epamba muminda ine hukama. Zvinoenderana nedata rakakodzera, 2015 kusvika parizvino, iyo yakazara kutakura yemukati yekuchengetedza yekutarisa indasitiri lithium bhatiri ingangoita 160 miriyoni, 2018 inotarisirwa kutumira anenge 160 miriyoni. Sekureva kweForesight Indasitiri Research Institute yekupa iyo yakadzika indasitiri data inoratidza kuti indasitiri yekutarisa chengetedzo seyese indasitiri cheni muindasitiri iri kukura zvakanyanya, nekuda kwehunhu hweindasitiri yayo uye yepasi pemvura inoda hunhu kune mimwe misiyano, saka remangwana indasitiri nzvimbo. yakakura.
Seyakanyanya kushandiswa muindasitiri yekutarisa kuchengetedza, iyo lithium bhatiri, maapplication ayo anovhara akasiyana emhando dzebhatiri, senge lithium-ion sekondari mabhatiri uye lithium-ion tertiary mabhatiri. Lithium-ion mabhatiri anoshandiswa muindasitiri yekuchengetedza anowanzo yakasimba electrolyte (electrolyte), uye yakasimba electrolyte mukugadzira maitiro anogona kupatsanurwa mumhando mbiri dzemakemikari vapor deposition uye electrodialysis nzira. Iyo kemikari vapor deposition method inzira iyo iyo yakasimba electrolyte inofanira kugadzirwa (yakadai sesilicon dioxide, lead dioxide) inosanganiswa nesimbi oxide-based zvinhu panzvimbo ye manganese oxide kana aluminium oxide, uye ipapo firimu rakatetepa rinowanikwa ne electrolyte. kuita se organic anode. Kubatsira kukuru ndiko kudhura kwakaderera uye hupenyu hurefu hwekutenderera; iyo yakashata ndeyokuti kushandiswa kunofanira kusanganiswa nekuwedzera reagents anobatsira (akadai seplasticizers) kune additives, iyo inodhura; uye kana pasina reagents anobatsira akawedzerwa, huwandu hwakawanda hwemagasi ane chepfu (formaldehyde, carbon dioxide) ichagadzirwa panguva yekushandiswa; uyezve, haigone kushandiswazve uye haigone kushandiswa zvakachengeteka. Kubva pamaitiro ebudiriro, kushandiswa kwayo sechinhu chekuchengetedza simba kuri kuwedzera kutariswa.
Mumakore achangopfuura, kuvandudzwa uye kushandiswa kwelithium-ion mabhatiridzave dzeruzhinji. Zvisinei, sezvo kuchine matambudziko akawanda ane lithium-ion mabhatiri, akadai sekushanda kusina kugadzikana, hupenyu hupfupi uye kuchengetedzwa kwakaderera, zvakakosha kukurumidza kukurumidza kwekutsvakurudza nekusimudzira kudzidza nekugadzirisa matambudziko aya. Zvinoenderana nekufanotaura, panosvika 2020, kutengesa kwemotokari nyowani yeChina kunotarisirwa kusvika mazana maviri ezviuru. Pakati pavo, saizi yemusika yemabhatiri e-lithium-ion yemotokari dzakangwara ichasvika kupfuura 3.6 bhiriyoni yuan.
Parizvino, zvinhu zvikuru zvakanaka uye zvisina kunaka zvinoshandiswa kune lithiamu-ion mabhatiri ndezvi: 1. NCM622 / 623: Pasi pemamiriro emutengo wakaderera, NCM522 inoshandiswa seanode, iyo inogona kuwana nzvimbo yakakwirira yepamusoro, uye zvakanakira yakagadzikana electrochemical performance, kuchengetedzwa kwakanaka uye hupenyu hurefu hwekutenderera; 2. GaN-based: Nyaya yacho pachayo ine unhu hwakanaka hwemuviri uye makemikari, kusanganisira corrosion resistance, kudhura kwakaderera, kushanda kwepamusoro uye zvimwe zvisingabatsiri kusangana neBattery negative electrode inokodzera lithium ion kana ichiratidza zvakanaka kuchengetedza kushanda. Nekuvandudzwa kwesainzi uye tekinoroji, zvinhu zvakawanda zvechizvarwa chitsva zvakabuda, senge ternary zvinhu. Parizvino, kune ternary seyakashata electrode yePack lithium mabhatiri pamusika, kuchengetedzwa kwayo uye simba remagetsi riri pamberi penyika, uye mutengo wakaderera, unogona kushandiswa mumagetsi evatengi. Ramangwana richaramba richitarisana nematambudziko maererano nekuchengeteka uye kutonga kwehutano.
Kubva pakuona kwehunyanzvi, nekushandiswa kwakapararira kwelithium mabhatirimumunda wekuchengetedza, iyo yese lithium bhatiri indasitiri inoratidzirwa neakakwira tekinoroji zvipingamupinyi, yakakwirira patent zvipingamupinyi uye yakaderera musika kusungwa. Zvinoenderana nedatha yelithium-ion mabhizinesi 'semi-pagore mishumo inoratidza kuti muna 2017, China yeLithium-ion bhatiri kugadzirwa uye kutengesa kwakapfuura bhiriyoni watt maawa. Pakati pavo, makambani gumi nematanhatu emumba lithium-ion bhatiri ari kutungamira indasitiri; ekunze Lithium bhatiri makambani anosanganisira SMC, FPC uye NCA makambani. Kunyanya, kune makambani matanhatu ari mumunda wezvigadzirwa zvekuchengetedza musika chikamu chinodarika gumi muzana, icho chikamu chemusika cheSkywing Intelligence chakasvika 14.5%, CASS Technology, Lixin bhatiri uye Zhongying Electronics chikamu chemusika che9.5%, 7.7% uye 5.2 %, zvichiteerana.
