Muna 2007, iyo "New Energy Vehicle Production Access Management Rules" yakashambadzirwa kuti ipe China mota nyowani dzemagetsi maindasitiri nhungamiro.Muna 2012, iyo "Energy-saving and New Energy Automobile Industry Development Plan (2012-2020)" yakaiswa pamberi uye yakava kutanga kweChina nyowani simba rekuvandudza mota.Muna 2015, "Chiziviso cheMatanho eKutsigira Kwemari Yekusimudzira uye Kushandiswa kweMotokari Itsva dzeMagetsi muna 2016-2020" chakaburitswa, izvo zvakavhura nhanganyaya yekuvandudzwa kwemotokari nyowani dzeChina.
Kuburitswa kwe "Kutungamira Maonero eKukurudzira Kuvandudzwa kweMagetsi Ekuchengetedza Tekinoroji uye Indasitiri" muna 2017 kwakaratidza kuputika kweindasitiri yekuchengetera magetsi uye kwakaita kuti 2018 kuve kutanga kwekukurumidza kusimudzira kweindasitiri yekuchengetera magetsi yeChina.Sezvinoratidzwa muMufananidzo 1, maererano nehuwandu hweChina Association of Automobile Manufacturers, kugadzirwa uye kutengesa kwemotokari itsva yeChina yakaratidza kukura kwekuputika kubva ku2012 kusvika ku2018;zvinoenderana ne "Energy Storage Industry Research White Paper 2019" yakapihwa neZhongguancun Energy Storage Indasitiri Technology Alliance Iyo inoratidza kuti iyo yakaiswa yeChina yemagetsi kemikari kuchengetedza simba yakawedzera zvakanyanya.Kubva muna 2017, iyo yakawedzera yakaiswa simba re lithium-ion bhatiri rekuchengetedza simba muChina yakaverengera makumi mashanu nesere muzana eiyo cumulative yakaiswa yemagetsi emagetsi ekuchengetedza simba.
Lithium-ion mabhatiri ane mabhenefiti ari pachena mumunda wekuchengetera magetsi emagetsi muChina, uye kumhanyisa magetsi emagetsi ekuchengetedza magetsi zvirinani uye zvakanyanya kugadzikana, zvinodikanwa kuti uongorore kuranga uye zvine hukama zvigadzirwa zvinobatanidzwa kubva kudivi rehunyanzvi.Sezvinoratidzwa mumufananidzo 2, ndiyo tekinoroji system yemagetsi emagetsi ekuchengetedza zvigadzirwa.Electrochemical-inoenderana nehunyanzvi zvigadzirwa (sero zvigadzirwa, module zvigadzirwa, simba rekuchengetedza masisitimu) inomiririrwa ne lithium-ion mabhatiri ndiwo moyo we electrochemical simba rekuchengetedza.Basa rezvimwe zvigadzirwa zvine hukama ndere kuona kuti electrochemical simba rekuchengetedza zvigadzirwa zvinoshanda zvirinani uye zvakanyanya kugadzikana
Kune zvigadzirwa zve lithium-ion bhatiri cell, iyo huru tekinoroji zvinhu zvinokanganisa mashandisirwo emagetsi emagetsi kuchengetedza hupenyu, chengetedzo, simba, uye simba, sezvakaratidzwa muMufananidzo 3. Mhedzisiro yehupenyu hwekutenderera inoenderana nezvinhu zvakaita senzvimbo yekushanda, mamiriro ekushanda, kuumbwa kwezvinhu, kufungidzira kurongeka, nezvimwewo;uye kuchengetedzwa kwekuongorora zviratidzo zvinonyanya zvinosanganisira magetsi-simba-thermal kuchengetedzwa uye zvimwe zvinodiwa zvekuchengetedza kwezvakatipoteredza, zvakadai semukati nekunze pfupi, Vibration, acupuncture, shock, overcharge, overdischarge, pamusoro pekushisa, humidity yakakwirira, kuderera kwemhepo, etc. The kufurira zvinhu zvesimba density zvinonyanya kukanganiswa neiyo zvinhu system uye maitiro ekugadzira.Izvo zvinopesvedzera zvinhu zvesimba maitiro zvinonyanya kuenderana nekugadzikana kwechimiro chechinhu, ionic conductivity uye emagetsi conductivity, uye tembiricha yekushanda.Nokudaro, kubva pamaonero ekugadzira lithium-ion battery cell products, kunyanya kutariswa kunoda kubhadharwa pakusarudzwa kwezvinhu, magadzirirwo emagetsi emagetsi (zvakanaka uye zvakashata zvinhu, N / P ratio, compaction density, nezvimwewo), uye maitiro ekugadzira (tembiricha Humidity control, coating process, liquid jekiseni maitiro, kemikari kutendeuka maitiro, nezvimwewo).
Kune zvigadzirwa zve lithium-ion bhatiri module, iyo huru yehunyanzvi zvinhu inokanganisa kushandiswa kwemagetsi emagetsi kuchengetedza ndeyekuenderana, kuchengetedzwa, simba, uye simba rebhatiri, sezvakaratidzwa muFigure 4. Pakati pavo, kuwirirana kwebhatiri cell yebhatiri. iyo module chigadzirwa chinonyanya hukama nekutonga kwemaitiro ekugadzira, tekinoroji zvinodikanwa zvebhatiri cell assembly, uye fungidziro yechokwadi.Kuchengetedzeka kwezvigadzirwa zvemodule kunoenderana nezvinodiwa zvekuchengetedza zvezvigadzirwa zvemasero ebhatiri, asi dhizaini zvinhu zvakaita sekuunganidza kupisa uye kupisa kupisa kunoda kutariswa.Iyo simba density yezvigadzirwa zvemodule inonyanya kuwedzera simba rayo kubva pamaonero eyakareruka dhizaini, nepo masimba ayo emagetsi achinyanya kutariswa kubva pamaonero ehutongi hwekupisa, hunhu hwesero, uye akateedzana-parallel dhizaini.Naizvozvo, kubva pakuona kwekugadzirwa kwe lithium-ion bhatiri module zvigadzirwa, kutarisisa kwakawanda kunoda kubhadharwa kune izvo zvinodikanwa zvekugadzirisa, lightweight dhizaini, mutsara-parallel dhizaini, uye kutonga kwekupisa.
