ʻO Bill Gates: nā kaʻa uila, nā mokulele mokulele? ʻAʻole paha lākou ka hopena.
ʻO ka manawa pinepine i ka mōʻaukala o Microsoft, ua ʻike ʻia i ka wā i haʻi ʻia ai ʻo Bill Gates ua hewa kekahi mea, ua hana mālie ʻo ia. No laila inā ʻōlelo ʻo Gates ʻaʻole kūpono nā mokulele uila a i ʻole nā kalaka a ke hoʻopukapuka nei i kahi hoʻomaka paʻa i ke kua, he mea hoihoi ia.
Ka lawe kaumaha o ka wā e hiki mai ana - uila a i ʻole biofuel?
ʻAʻole maoli ʻo Bill Gates he loea a me ka loea kaʻa uila. Akā naʻe ua hoʻopukapuka ʻo ia i QuantumScape, ka mea e kaena nei i nā cell electrolyte paʻa. Ma waena o nā mea ʻē aʻe, e hoʻohana ʻia kāna kālā no ka hoʻomaka mua ʻana o kahi hoʻomaka ʻana he 3,3 biliona kālā US (e like me 12,4 biliona zlotys).
Loaʻa iā Volkswagen a me Continental nā kuleana ma QuantumScape.
He liʻiliʻi ka ʻike e pili ana i nā cell i hoʻomaka ʻia. Wahi a ka hui, hoʻohana lākou i kahi electrolyte paʻa a ʻaʻohe anode maʻamau. ʻOiaʻiʻo, ʻaʻole kūpono nā cell electrode hoʻokahi. ʻO kēia "ʻaʻohe anode" ʻo ia hoʻi "ʻaʻohe anode prefabricated", graphite a i ʻole graphite silicon layer. Hoʻokumu ʻia ka anode ma ka hui ʻana o ka electrode lua a loaʻa i nā atom lithium i hoʻokuʻu ʻia e ka cathode i ka wā o ke kaʻina hana.
I ka pōkole: ke hana nei mākou me ka metala lithium, nā pūnaewele metala lithium:
ʻAʻole pono ka hoʻomākaukau anode ma ka hale hana emi iho na koina hana... Pono e unuhi ʻia kēia i ʻoi aku ka nui o ke keleponaʻoiai ʻo ka helu o nā ʻātoma lithium ma ka cathode e like me ka maʻamau lithium-ion cell. No ke aha mai?
He mea maʻalahi: me ka ʻole o kahi anode graphite, ʻoi aku ka māmā a me ka lahilahi o ke kelepona a hiki ke mālama i ka uku like (= no ka mea, ua manaʻo mākou ua like ka helu o nā atom lithium). No laila, hoʻonui ka gravimetric (kaupaʻa-kaupaʻa) a me ka nui (pili i ka volume) ka nui o ka ikehu cell.
ʻO nā pūnaewele liʻiliʻi e hoʻopaʻa i ka uku hoʻokahi e hiki ai i nā cell hou ke komo i loko o ke keʻena pākaukau, ʻo ia hoʻi, ʻoi aku ka nui o ka mana o ka pila. ʻO kēia ka mea a QuantumScape i hoʻohiki ai.
I kēia manawa, manaʻoʻiʻo ʻo Bill Gates ʻaʻole hiki i nā moku ukana uila, nā mokulele mokulele a me nā kaʻa ke lilo i mea hoʻonā kūpono ma muli o ke kaumaha kaumaha o nā pā. Ma muli o ka nui o lākou, ua hoʻonui ʻo DAF i ka laulā o kāna tractor i ʻoi aku ma mua o 200 mau kilomita, e hoʻonui ana i ka mana pākaukau i 315 kWh:
> Ua hoʻonui ʻo DAF i ka laulā o ka CF Electric i 200 mau kilomita.
Hiki iā mākou ke helu maʻalahi i kēlā ʻO ka hoʻonui ʻana i ka laulā a hiki i 800 mau kilomita e koi i ka hoʻohana ʻana i ʻoi aku ma mua o 1,1 MWh o nā cell e kaupaona ana ma ka liʻiliʻi he 7-8 tons.... No Gates, he nāwaliwali kēia a, e like me kāna ʻōlelo ʻana, he pilikia hiki ʻole ke hoʻopau ʻia.
Akā naʻe, ʻaʻole ʻae ka poʻe e pili ana i kēia kumuhana. Manaʻo ʻo Elon Musk he mea kūpono nā mokulele uila ke pā mākou i ka 0,4 kWh / kg. I kēia lā ke hoʻokokoke nei mākou i ka 0,3 kWh / kg, a ʻōlelo kekahi mau mea hoʻomaka ua hiki lākou i ka 0,4 kWh / kg:
> Imec: loaʻa iā mākou nā pūnaewele electrolyte paʻa, ka ikaika o ka ikehu 0,4 kWh / lita, uku 0,5C
Akā ke manaʻoʻiʻo nei ka mea hoʻokumu ʻo Microsoft e ʻoi aku ka maikaʻi o nā biofuels no nā kaʻa nui a kaumaha. He wahie uila, hydrocarbons i loaʻa mai ka wai a me carbon dioxide mai ka lewa (kumu). ʻO ia ke kumu i hoʻoholo ai ʻo ia e hoʻokomo i kahi hui e pili ana i nā cell electrolyte paʻa?
Palapala hoʻoponopono www.elektrowoz.pl: He kumuhana hoihoi nā loulou QuantumScape. E hoʻi mākou iā lākou ma hope 🙂
