Senguva yerubatsiro rwenyika yangu itsva mota yemagetsi kudzikira zvakazara, LG Chem, Samsung SDI, Panasonic nedzimwe mhiri kwemakungwa simba relithium-ion bhatiri hofori dziri kuunganidza simba radzo muchivande, dzichida kutora mukana weiyo inotungamira mukana wekubvisa iyo inouya isiri-. musika werubatsiro.

Imwe yemabhenefiti avo ekutanga ndeyekutsvagisa tekinoroji yebhatiri uye mukana wekusimudzira unotungamira kuvandudzwa kwesimba repasi rose lithium-ion bhatiri indasitiri.

➤LG Chem: Tsvagiridzo yezvinyorwa + inoenderera mberi nekudyara kwepamusoro

LG Chem inoshanda pamwe neOEMs inovhara akawanda epasi rose mhando seAmerica, Japanese, uye Korean. Iyo ine yakadzama yekutsvagisa mabhenefiti mumunda wezvinhu zvakakosha, uye panguva imwechete inotarisa “Motokari Battery Development Center” sesangano rakazvimirira rechikamu chebhizinesi rebhatiri, sezvakaratidzwa mumufananidzo unotevera:

Nemakumi emakore emabhenefiti mukutsvaga kwezvinhu, LG Chem inogona kuunza yakasarudzika matekinoroji mune zvakanaka uye zvisina kunaka zvinhu, zvinopatsanura, nezvimwewo, mukugadzirwa kwechigadzirwa kekutanga, uye zvakananga kuratidza yakasarudzika tekinoroji musero tsvakiridzo nekusimudzira maitiro. Iyo inogona kupa iyo yese chigadzirwa portfolio ine chekuita nemagetsi lithium-ion mabhatiri kubva kuSero, module, BMS, uye Pack kusimudzira kune tsigiro yehunyanzvi.

Kutsigira kutsvagisa uye kusimudzira tekinoroji yeLG Chem inotsigirwa mari yakawanda. Maererano neongororo data, LG Chem yose R&D mari uye manpower investimendi yakaramba ichikwira kubva 2013. Pakazosvika 2017, R&D investment yakasvika 3.5 bhiriyoni yuan (RMB), iri kutanga pakati pemakambani ebhatiri epasi rose muR&D investment gore iroro.

Iwo mabhenefiti ezvishandiso zvekukwira kumusoro zvigadziriso uye kugona kwakazvimirira kwekugadzira zvinongedzo zvinopa vimbiso yakasimba ye LG Chem’s ternary nyoro pasuru nzira ine yakakwira yakazara mutengo uye yakakwirira tekinoroji zvikumbaridzo.

Panyaya yekuvandudza nzira yehunyanzvi, LG Chem parizvino iri kushanda nesimba kubva pakapfava pasuru NCM622 kuenda kuNCM712 kana NCMA712.

Mubvunzurudzo nevatori venhau, iyo CFO yeLG Chemical yakataura kuti iyo kambani yakanaka electrode zvinhu kusimudzira nzira kubva pa622 kusvika 712 kana kunyange 811, LG ine hurongwa hwakasiyana hwekufananidza iyo yakapfava pasuru nzira uye cylindrical nzira uye mashandisirwo ezasi rwizi. mhando (iyo yakapfava package haizogadziriswi kwenguva 811, Uye iyo cylindrical NCM811 parizvino inoshanda chete kumabhazi emagetsi).

Nekudaro, ingave iri NCMA yakanaka electrode kana NCM712 yakanaka electrode, LG Chem’s misa yekugadzira hurongwa yakarongerwa angangoita makore maviri, inova yakanyanya kuchengetedza kupfuura chirongwa chePanasonic chepamusoro-nickel nzira.

➤Samsung SDI: Kudyidzana nemasangano ekutsvagisa + inoenderera yakakwira-yakanyanya kudyara

Samsung SDI inotora muenzaniso wekudyidzana wakafanana neCATL mumunda wekutsvagisa nekusimudzira: inoshanda pamwe nevekunze nevekunze yunivhesiti yekutsvagisa masangano kumisikidza yakakosha nyaya dzehunyanzvi, kugadzirisa budiriro yekutengeserana pamwe chete, uye pamwe chete kusimudzira zvirongwa zvekutsvagisa kugadzira synergies.

Samsung SDI uye LG Chem vane nzira dzakasiyana dzehunyanzvi. Iwo akanyanya kuita mativi mana. Panguva imwecheteyo, ivo vanoshingairira kutevera kugadzirwa kwe21700 mabhatiri. Iyo cathode zvinhu zvinonyanya kushandisa ternary NCM uye NCA zvinhu. Nekudaro, mari yayo mukutsvaga nekusimudzira zvakare yakasimba kwazvo.

Zvinoenderana nedata reongororo, Samsung SDI’s R&D investimendi muna 2014 yakasvika 620,517 miriyoni yakahwina, inoverengera 7.39% yekutengesa; R&D investimendi muna 2017 yaive 2.8 bhiriyoni yuan (RMB). Nezve nyaya dzakakosha mumunda wemabhatiri echizvarwa chinotevera uye zvigadzirwa, nekutsigira kuvandudzwa kwezvibvumirano zvine hukama zvakanyanya nenyaya, isu tichaongorora kukwikwidza patent uye kuvhura nzvimbo nyowani dzebhizinesi.

Samsung SDI prismatic bhatiri yasvika padanho re210-230wh/kg simba density.

Sekureva kwaWei Wei, mutevedzeri wemutungamiri weSamsung SDI nyika yangu paMagetsi Vehicle Forum yegore rino, Samsung ichavandudza chizvarwa chechina chezvigadzirwa kubva kune cathode zvinhu (NCA nzira), electrolyte uye anode tekinoroji mune ramangwana. Mushure mekutangisa bhatiri rechizvarwa chechina rine simba re 270-280wh/kg, rinoronga kuenderera mberi nekugadzira chigadzirwa chechishanu chechizvarwa chine simba rakarongwa re 300wh / kg kune yakakwirira nickel nzira.

Iyo kambani nzvimbo yekusimudzira masikweya inosanganisirawo “yakaderera-kureba mabhatiri” ane yakagadziridzwa modhi saizi, kuunzwa kwezvinhu zvinokurumidza kuchaja, uye mapakeji akareruka. Pamusoro pemabhatiri eprismatic, Samsung SDI zvakare ine dhizaini mumunda weakasimba-state mabhatiri uye cylindrical mabhatiri. Muna 2017, Samsung SDI yakaratidza mabhatiri akasimba-mamiriro uye mamodule ebhatiri akavakirwa pamaseru 21700 cylindrical kuNorth American Auto Show, zvichiratidza kugona kusimudzira munzira dzakawanda.

Zvakakodzera kutaura kuti Samsung SDI inotsigirwa neSamsung Group’s yakasimba R&D uye simba rekushandisa, uye zvakare inokwanisa kupa simba lithium-ion bhatiri mhinduro kune yese indasitiri cheni.

➤Panasonic: Zvakanakira cylinder + inotsigira Tesla

Muna 1998, Panasonic yakatanga kugadzirwa kwakawanda kwecylindrical lithium-ion mabhatiri emakomputa ekunyorera uye yakavaka indasitiri inotungamira kugadzirwa kwemabhatiri e-lithium-ion. Muna Mbudzi 2008, Panasonic yakazivisa kubatanidzwa neSanyo Electric uye ikava mutengesi mukuru wepasi rose we lithium-ion mabhatiri.

Panasonic’s R&D dhizaini mumunda wemagetsi lithium-ion mabhatiri yakavakirwa pakubatana kwayo kwenguva refu nemhando dzakadai seTesla neToyota, yakatarisana nemisika yeJapan neAmerica. Hwaro hwakasimba hwayakaunganidza mubhizinesi remutengi lithium bhatiri yakawedzera mabhenefiti eiyo cylindrical nzira yekukura tekinoroji uye yakakwirira kuenderana, uye yakawana yakakura-simba density uye yakagadzikana cycle bhatiri module yakakodzera Tesla modhi.

Tichitarisa kumashure kuzvizvarwa zvakapfuura zvePanasonic mabhatiri akashongedzerwa kubva kuRoadster kuenda kuModel 3 nhasi, kuvandudzwa kwehunyanzvi hwekuita nzira inonangana mukuvandudzwa kweiyo cathode zvinhu uye saizi yecylinder.

Panyaya yemidziyo yecathode, Tesla akashandisa lithium cobalt oxide cathodes mumazuva ekutanga, ModelS yakatanga kuchinjika kuNCA, uye iko zvino kushandiswa kwepamusoro-nickel NCA paModel 3, Panasonic yanga iri mumutungamiri weindasitiri mukuvandudza zvinhu zvecathode mukutsvaga. ye high energy density.

Pamusoro peiyo yakanaka electrode zvinhu, iyo cylindrical nzira yakashanduka kubva kurudzi rwe18650 kuenda kurudzi rwe21700, uye maitiro ekutsvaga yakakura simba remagetsi resero rimwe chete rinotungamirwa nePanasonic. Ndichiri kusimudzira kuvandudzwa kwekuita kwebhatiri, mabhatiri mahombe anoderedza kuoma kwepack system manejimendi uye kuderedza mutengo wesimbi zvimiro zvikamu uye conductive yekubatanidza yebhatiri pack, nekudaro kuderedza mitengo uye kuwedzera simba density.
