Mea Anode Kūlana Kiʻekiʻe Pre-Magnesium Silicon-Oxygen-Carbon Pre-Mg-SiOC

ʻIkepili o ka Pre-Magnesium Silicon-Oxygen-Carbon

ʻO ka Pre-Magnesium Silicon-Oxygen-Carbon (Pre-Mg-SiOC) kahi mea anode pākahiko lithium-ion hanauna hou i hoʻomohala ʻia ma o kahi hana pre-magnesiation a me ke kaʻina hana carbon composite e hoʻohana ana i ka silicon oxide ma ke ʻano he mea maka. I ka wā o ka hana ʻana, hoʻokomo ʻia ka magnesium i nā pae paʻa e like me ka magnesium silicate i loko o ka mea. Hoʻomaikaʻi nui kēia i ka pono Coulombic mua (ICE). I ka manawa like, ʻo ke kākoʻo mechanical i hāʻawi ʻia e ka ʻōnaehana magnesium silicate e pale pono i ka hoʻonui ʻana o ka nui i ka wā o nā pōʻaiapuni hoʻouka/hoʻokuʻu, no laila e hoʻolōʻihi ana i ke ola o ke kaʻina hana cell.

Hōʻike kēia huahana i ka ʻenehana anode silicon-oxygen hanauna ʻelua. Ke hoʻohālikelike ʻia me nā anodes SiOx hanauna mua maʻamau, loaʻa iā ia kahi holomua kupaianaha i ka pono mua, e hāʻawi ana i kahi hopena anode hana kiʻekiʻe, kūpono i ke kaʻina hana no nā ʻōnaehana pila kiʻekiʻe-ikehu.

Nā Hiʻohiʻona o Pre-Magnesium Silicon-Oxygen-Carbon

• Hoʻonui nui ʻia ka pono mua: Ma o ka pre-magnesiation, ua hoʻokumu mua ʻia nā pae magnesium silicate paʻa, e pale ana i ka hoʻopau ʻana o ka lithium hana i hiki ʻole ke hoʻihoʻi ʻia. ʻOi aku ka kiʻekiʻe o ka pono Coulombic mua ma mua o nā anodes SiOx maʻamau, me nā waiwai maʻamau mai 80% a 83% a ʻoi aku ka nui o nā waiwai kiʻekiʻe ma mua o 89%.
• Ka Hoʻonui ʻana i ka Leo Kūpono: Hāʻawi ka pae magnesium silicate i ke kākoʻo mechanical ikaika. I hui pū ʻia me ka ʻōnaehana porous hāmama o ka mea, hoʻēmi pono ia i nā loli leo i ka wā o ka lithiation, e hōʻoiaʻiʻo ana i ka pono o nā ʻāpana a me ke kūpaʻa o ke kūkulu ʻana o ka electrode.
• Uhi Kalapona Alakaʻi: Hoʻonui ka uhi kalapona ʻili i ka conductivity uila, kāohi i ka ʻino electrolyte pololei ma ka anode, a paipai i ka hoʻokumu ʻana o kahi kiʻiʻoniʻoni solid-electrolyte interphase (SEI) paʻa, e alakaʻi ana i ka paʻa paikikala kiʻekiʻe.
• Hoʻohālikelike Kaʻina Hana Maikaʻi Loa: Me ka hoʻolaha like ʻana o ka nui o nā ʻāpana a me kahi puka makani hana ākea, kūpono kēia mea me nā ʻōnaehana mea hoʻopaʻa like ʻole, me PVDF, PAA, a me CMC/SBR. Hōʻike pū ia i ka launa maikaʻi i ka wā e hui pū ʻia me nā mea graphite anode.

He kūpono loa kēia huahana no nā ʻōnaehana pila cylindrical a me nā ʻōnaehana pila pouch .

Pūʻolo o Pre-Magnesium Silicon-Oxygen-Carbon

Hoʻopaʻa ʻia ka huahana i loko o nā ʻeke pale wai, a laila waiho ʻia i loko o nā pahu pepa. Hiki ke hoʻopilikino ʻia ke kaumaha o ka ʻōpala e like me nā koi o ka mea kūʻai.
