Ua hoʻomaikaʻi ʻo Tesla co-founder JB Straubel i ka hoʻomaka ʻana o ka mokuʻāina paʻa. Hele lehulehu ka hui.
ʻO JB Straubel he Tesla Engineer, Cell and Battery Technician. I ka makahiki 2019, ua haʻalele ʻo ia i ka ʻoihana e hana i kahi ʻoihana hoʻihoʻi pākaukau lithium-ion. A i kēia manawa ʻo ia ka Luna Nui o kahi hoʻomaka pākaukau electrolyte paʻa: QantumScape.
Inā e kaena ʻo J. B. Strobel i kekahi mea, ʻaʻole paha nāwaliwali
I ka wā o kekahi o nā ʻaha kūkā, ʻo Elon Musk - ma hope ona ma ke kahua ʻo J. B. Straubel - i ʻōlelo ākea ʻoiai e hana ana ma Tesla, ua hoʻāʻo paha lākou i nā cell āpau. Ua hoʻohana lākou i nā mea a lākou i hoʻohana ai, i hana ʻia me Panasonic, akā ʻoiaʻiʻo, kono lākou i [nā mea noiʻi] makemake e hōʻoia iā lākou he huahana ʻoi aku ka maikaʻi. No ka mea ua "ho'āʻo" lākou a kūʻai kūleʻa i nā kaʻa uila, ua ʻoi aku ka maikaʻi o ka hoʻomaopopo ʻana i kā lākou mea e kamaʻilio nei.
ʻO J. B. Straubel i ka wā hana mua ma ka Tesla Roadster (c) Tesla cell packs
I kēia manawa, ma hope o ka haʻalele ʻana iā Tesla, aia ʻo J. B. Straubel ma ka papa alakaʻi o ka hoʻomaka QuantumScape. I mai la ia.
ʻO ka hoʻolālā kelepona me ka ʻole o ka anode a me ka electrolyte paʻa [i hana ʻia e] QuantumScape ʻo ia ka hoʻolālā pākaukau lithium nani loa aʻu i ʻike ai. Loaʻa i ka hui ke hoʻololi hou i ka ʻāpana pākahi.
Ua hoʻonui ʻia ʻo QuantumScape ma luna o $ 700 miliona mai nā mea hoʻopukapuka ʻoihana (me SAIC a me Volkswagen) a ua hele i ka lehulehu. Ke hoʻomohala nei ka hoʻomaka ʻana i nā cell electrolyte paʻa e hoʻohiki ai i ka nui o ka ikehu kiʻekiʻe ma mua o nā cell electrolyte wai lithium-ion.
ʻO ka electrolyte paʻa i loko o ke kelepona - ma waho aʻe o ka hoʻemi ʻana i ka hopena o ke ahi - ke kāohi nei i ka ulu ʻana o nā lithium dendrites, kahi e alakaʻi ai i kahi pōkole pōkole a me ka pōʻino i nā cell i loko. ʻO ia ke ʻano o ka anode o ke kelepona hiki ke hana ʻia mai ka lithium maʻemaʻe ma mua o ka graphite a i ʻole silika e like me ka hana i kēia lā. A no ka mea, he lithium maʻemaʻe ka mea lawe ikehu, pono e hoʻonui ʻia ka mana o ke kelepona e 1,5-2 mau manawa i hoʻohālikelike ʻia i nā cell lithium-ion maʻamau.
ʻOi aku ka maikaʻi: hiki ke hoʻopiʻi ʻia kahi cell electrolyte lithium metala paʻa me ka mana kiʻekiʻe a pono e decompose mālie. No ka mea, ʻaʻole e hopu ʻia nā mea lithium e ka graphite / silicon / SEI layer structures, akā e neʻe manuahi i hope a i waho.
ʻOiai ke hana nei ʻo QuantumScape i nā hōʻikeʻike i kāna mau mea hoʻopukapuka, mai manaʻo e hoʻopili koke ʻia nā cell o ka hui i nā kaʻa. ʻOiai inā ua mākaukau nā pūnaewele a aia kekahi e makemake e noho ma mua o ka hoʻokūkū me ka hoʻohana ʻana i nā huahana QuantumScape, e lawe ʻia nā makahiki 2-3 e hoʻokō i ka hopena. He nui nā hui e haʻi pololei ana he mele nā pilina aupuni paʻa e pili ana i ka wā e hiki mai ana, ma kahi o ka hapa ʻelua o kēia ʻumi makahiki:
> Hoʻohana ʻo LG Chem i nā sulfide i loko o nā pūnaewele mokuʻāina paʻa. ʻAʻole ma mua o 2028 ka hoʻolaha ʻana o ka electrolyte paʻa
Pono e ʻike ʻia, kahi hoʻolauna pōkole i ke ʻano o ka hana ʻana o ka wai a me nā cell electrolyte paʻa:
E hoihoi paha kēia iā ʻoe:
