He pule hou a me ka pākaukau hou. I kēia manawa, hana ʻia nā electrodes i nā nanoparticles o ka manganese a me ka titanium oxides ma kahi o ka cobalt a me ka nickel
Nā mea
Ua paʻi nā kānaka ʻepekema mai ke Kulanui o Yokohama (Iapana) i kahi pepa noiʻi e pili ana i nā cell kahi i pani ʻia ai ka cobalt (Co) a me ka nickel (Ni) e nā oxides o ka titanium (Ti) a me ka manganese (Mn), i hoʻokumu ʻia i kahi pae i ka nui o nā ʻāpana. aia i loko o nā haneli. nanometer. Pono e ʻoi aku ka liʻiliʻi o nā cell i ka hana ʻana a hiki ke hoʻohālikelike a ʻoi aku ka maikaʻi ma mua o nā cell lithium-ion hou.
ʻO ka loaʻa ʻole o ka cobalt a me ka nickel i nā pā lithium-ion ʻo ia hoʻi nā kumukūʻai haʻahaʻa.
Ka papa o nā mea
- ʻO ka loaʻa ʻole o ka cobalt a me ka nickel i nā pā lithium-ion ʻo ia hoʻi nā kumukūʻai haʻahaʻa.
- He aha ka mea i loaʻa ma Iapana?
Hana ʻia nā cell lithium-ion maʻamau me ka hoʻohana ʻana i nā ʻenehana like ʻole a me nā ʻāpana like ʻole o nā mea a me nā pūhui kemika i hoʻohana ʻia i ka cathode. ʻO nā ʻano mea nui loa:
- NCM a i ʻole NMC - ʻo ia hoʻi. ma muli o ka nickel-cobalt-manganese cathode; hoʻohana ʻia lākou e ka hapa nui o nā mea hana kaʻa uila,
- NKA - i.e. ma muli o ka nickel-cobalt-aluminum cathode; Hoʻohana ʻo Tesla iā lākou
- LFP - ma muli o ka hao phosphates; Hoʻohana ʻo BYD iā lākou, hoʻohana kekahi mau mea Kina i nā pahi,
- LCO - e pili ana i ka cobalt oxides; ʻAʻole mākou ʻike i kahi mea hana kaʻa e hoʻohana iā lākou, akā aia lākou i ka uila,
- LMO - i.e. ma muli o ka manganese oxides.
Hoʻomaʻamaʻa ʻia ka hoʻokaʻawale ʻana e ka loaʻa ʻana o nā loulou e hoʻopili i nā ʻenehana (no ka laʻana, NCMA). Eia kekahi, ʻaʻole ka cathode nā mea āpau, aia kekahi electrolyte a me kahi anode.
> ʻO Samsung SDI me ka pākaukau lithium-ion: i kēia lā graphite, silikoni koke, liʻiliʻi liʻiliʻi me nā metala liʻiliʻi a me kahi ākea o 360-420 km i ka BMW i3
ʻO ka pahuhopu nui o ka nui o ka noiʻi ʻana i nā cell lithium-ion ʻo ia ka hoʻonui ʻana i ko lākou hiki (ke ikehu), ka palekana o ka hana a me ka wikiwiki o ka hoʻouka ʻana i ka wā e hoʻonui ai i ko lākou ola lawelawe. oiai e hoemi ana i na koina... ʻO nā kumu kūʻai nui e loaʻa mai ka hoʻopau ʻana i ka cobalt a me ka nickel, nā mea waiwai nui ʻelua, mai nā cell. He pilikia nui ʻo Cobalt no ka mea ʻeli ʻia ma ʻApelika, hoʻohana pinepine i nā keiki.
ʻO nā mea hana kiʻekiʻe loa i kēia lā aia i nā huahelu hoʻokahi (Tesla: 3 pakeneka) a i ʻole ma lalo o 10 pakeneka.
He aha ka mea i loaʻa ma Iapana?
Ua ʻōlelo ka poʻe noiʻi ʻo Yokohama Ua hiki iā lākou ke hoʻololi piha i ka cobalt a me ka nickel me ka titanium a me ka manganese. No ka hoʻonui ʻana i ka capacitance o nā electrodes, hoʻoheheʻe lākou i kekahi mau oxides (malia paha manganese a me titanium) no laila he mau haneli nanometer ko lākou nui. ʻO ka grinding kahi ʻano hana maʻamau no ka mea, hāʻawi ʻia i ka nui o ka mea, hoʻonui ia i ka ʻili o ka mea.
Eia kekahi, ʻoi aku ka nui o ka ʻili, ʻoi aku ka nui o nā nooks a me nā māwae i ka hale, ʻoi aku ka nui o ka mana electrode.
Hōʻike ka hoʻokuʻu ʻana ua kūleʻa nā ʻepekema i ka hana ʻana i kahi prototype o nā cell me nā waiwai hoʻohiki a ke ʻimi nei i nā hoa hana i nā ʻoihana hana. ʻO ka hana aʻe e hoʻāʻo nui i ko lākou hoʻomanawanui, a ma hope o ka hoʻāʻo ʻana i ka hana nui. Inā hoʻohiki ko lākou mau palena, e hōʻea lākou i nā kaʻa uila ma mua o 2025..
E hoihoi paha kēia iā ʻoe:
