Samsung tshaj tawm rau lub Peb Hlis 14 tias nws tau tawg hauv av ntawm 6,500-square-meter tag nrho cov khoom-lub xeev roj teeb kuaj kab ntawm qhov chaw ntawm nws qhov chaw tshawb fawb hauv Yeongtong-gu, Suwon-si, Gyeonggi-do. Lub tuam txhab hu nws “S-Line,” qhov twg S stands rau “Solid,” “Sole,” thiab “Samsung SDI.”

Samsung SDI npaj yuav ua kom paub cov roj teeb ntshiab electrode daim hlau, cov khoom siv electrolyte ua thiab cov khoom siv roj teeb sib dhos ntawm S-Line. Txog tam sim no, lub tuam txhab tau ua ib lossis ob qho qauv hauv chav kuaj. Thaum S-Line ua tiav, kev tsim khoom loj loj yuav ua tau.

Cov roj teeb tag nrho-lub xeev muaj cov khoom siv electrolytes, yog li tsis tshua muaj kev pheej hmoo ntawm hluav taws. Thaum lawv muaj lub zog ceev ceev, cov roj teeb hauv lub xeev kuj tau ntseeg tias yog qhov hloov pauv kev ua si.

Samsung SDI tab tom tsim lub roj teeb uas muaj zog nrog sulfide-based electrolyte. Piv nrog rau polymer oxide-raws li electrolytes, cov electrolyte no muaj qhov zoo nyob rau hauv cov nqe lus ntawm scale-up ntawm ntau lawm thiab them ceev. Samsung SDI tau txais cov qauv tsim thiab patent ntawm cov khoom siv sulfide electrolyte thiab tau nkag mus rau theem kev tshawb fawb thev naus laus zis.

“Kev tsim kho ntawm txoj kab xeem txhais tau hais tias Samsung SDI tau kov yeej cov teeb meem kev lag luam ntawm kev tsim khoom loj ntawm tag nrho cov khoom siv-xeev roj teeb rau qee yam,” ib qho kev lag luam hais.

Qhov teeb meem loj tshaj plaws tam sim no yog cov thev naus laus zis los xyuas kom them sai dua ntawm chav tsev thiab qhov kub thiab txias. Lub ionic conductivity ntawm cov khoom electrolytes yog qis dua li ntawm cov kua electrolytes, yog li tus nqi-tso tawm ntawm tag nrho cov-solid-state roj teeb yog qis dua li cov pa roj teeb.

Cov kab tsav tsheb yuav coj Samsung SDI los ze zog rau cov khoom loj ntawm tag nrho cov khoom-lub xeev cov roj teeb dua li nws cov neeg sib tw. LG Energy Solution thiab SK On tab tom tsim tag nrho cov khoom siv hluav taws xob hauv lub xeev nrog lub hom phiaj ntawm kev pib ntau lawm nyob ib ncig ntawm 2030.

Ntawm cov roj teeb pib, Volkswagen-rov qab QuantumScape npaj yuav pib tsim khoom loj ntawm tag nrho cov khoom-lub xeev cov roj teeb thaum ntxov li 2024. Lub Hwj Chim Loj, uas muaj BMW thiab Ford ua cov tswv lag luam loj, kuj tau tshaj tawm tias nws yuav tso tsheb hluav taws xob nrog cov roj teeb hauv lub xeev. nyob rau hauv 2025. SES, txhawb nqa los ntawm Hyundai Motor Co thiab General Motors (GM), kuj vam tias yuav ua lag luam lithium roj teeb los ntawm 2025.

Lub caij no, Samsung SDI tau tshem tawm nws lub tuam txhab Wuxi-based roj teeb pob SWBS hauv lig 2021, raws li cov khoom siv roj teeb. Samsung SDI yav dhau los ua tiav qhov kev tshem tawm ntawm lwm lub tuam txhab roj teeb, SCPB, raws li hauv Changchun, Tuam Tshoj, thaum ntxov 2021. Vim li ntawd, Samsung SDI tau thim tawm tag nrho cov lag luam roj teeb hauv Suav teb.

Samsung SDI tab tom npaj tsom mus rau kev lag luam roj teeb ntawm tes hauv Tianjin thiab Xi’an los ntawm kev kaw tag nrho nws cov roj teeb pob hauv Suav teb.
