Nā ʻano o nā Bateri Lithium-ion
Hōʻike ka Figure 1 i ke kaʻina hana.
ʻO ka Li-ion kahi pākaukau haʻahaʻa haʻahaʻa, kahi pōmaikaʻi ʻaʻole hiki ke koi ʻia ka hapa nui o nā kemika ʻē aʻe.ʻAʻohe hoʻomanaʻo o ka pākaukau a ʻaʻole pono e hoʻomaʻamaʻa (deliberate full discharge) no ka mālama ʻana i ke ʻano maikaʻi.ʻOi aku ka liʻiliʻi o ka hoʻokuʻu ʻana iā ia iho ma mua o ka hapalua o nā ʻōnaehana nickel-based a kōkua kēia i nā noi ana i ka wahie.Hiki i ka volta cell nominal o 3.60V ke hoʻohana pololei i nā kelepona paʻalima, nā papa a me nā kiʻi kamepiula, e hāʻawi ana i nā maʻalahi a me nā hōʻemi ʻana o nā kumukūʻai ma luna o nā hoʻolālā multi-cell.ʻO nā drawbacks ka pono o nā kaapuni pale e pale aku i ka hana ʻino, a me ke kumukūʻai kiʻekiʻe.
Ua hoʻohana ʻia ka pahu lithium-ion mua o Sony i ka coke ma ke ʻano he anode (huahana lanahu).Mai ka makahiki 1997, ua neʻe ka hapa nui o nā mea hana Li ion, me Sony, i ka graphite e loaʻa i kahi pihi hoʻokuʻu palahalaha.ʻO ka graphite kahi ʻano kalapona i paʻa ka pōʻaiapuni lōʻihi a hoʻohana ʻia i nā penikala alakaʻi.ʻO ia ka mea kalapona maʻamau, ukali ʻia e nā kalapona paʻakikī a palupalu.ʻAʻole i loaʻa i nā kalapona Nanotube ka hoʻohana pāʻoihana i ka Li-ion no ka mea e hoʻopili lākou a pili i ka hana.ʻO kahi mea e hiki mai ana e hoʻohiki e hoʻonui i ka hana o Li-ion he graphene.
Hōʻike ka Kiʻi 2 i ka pihi hoʻokuʻu uila o kahi Li-ion hou me ka anode graphite a me ka mana coke mua.
Ua ho'āʻo ʻia kekahi mau mea hoʻohui, e komo pū me nā mea hoʻohui silika, e hoʻoikaika i ka hana o ka anode graphite.Lawe ʻo ia i ʻeono carbon (graphite) atoms e hoʻopaʻa i hoʻokahi lithium ion;hiki ke hoʻopaʻa ʻia kahi ʻātoma silika hoʻokahi i ʻehā lithium ion.ʻO ia ka mea hiki i ka anode silicon ke mālama ma mua o 10 mau manawa o ka ikehu o ka graphite, akā pilikia ka hoʻonui ʻana o ka anode i ka wā o ka hoʻouka ʻana.No laila ʻaʻole pono nā anodes silicone maʻemaʻe a ʻo 3-5 wale nō ka nui o ke silika i hoʻohui pinepine ʻia i ka anode o kahi silicon-based no ka loaʻa ʻana o ke ola pōʻai maikaʻi.
ʻO ka hoʻohana ʻana i ka lithium-titanate nano-structured ma ke ʻano he anode additive e hōʻike ana i ke ola pōʻaiapili hoʻohiki, nā hiki ke hoʻouka maikaʻi, ka hana haʻahaʻa haʻahaʻa maikaʻi loa a me ka palekana kiʻekiʻe, akā haʻahaʻa ka ikehu kikoʻī a kiʻekiʻe ke kumukūʻai.
ʻO ka hoʻāʻo ʻana me ka cathode a me nā mea anode e hiki ai i nā mea hana ke hoʻoikaika i nā ʻano intrinsic, akā hiki i kekahi hoʻonui ke hoʻololi i kekahi.ʻO ka mea i kapa ʻia ʻo "Energy Cell" e hoʻomaikaʻi i ka ikehu kūikawā (hiki) e hoʻokō i nā manawa lōʻihi akā ma ka mana kikoʻī haʻahaʻa;Hāʻawi ka "Power Cell" i ka mana kūikawā akā ma ka haʻahaʻa haʻahaʻa.ʻO ka "Hybrid Cell" kahi kuʻikahi a hāʻawi iki i nā mea ʻelua.
Hiki i nā mea hana ke loaʻa ka ikehu kikoʻī kiʻekiʻe a me ke kumu kūʻai haʻahaʻa me ka maʻalahi ma ka hoʻohui ʻana i ka nickel ma kahi o ka cobalt ʻoi aku ka pipiʻi, akā ʻoi aku ka paʻa o ke kelepona.ʻOiai hiki i kahi ʻoihana hoʻomaka ke kālele i ka ikehu kikoʻī kiʻekiʻe a me ke kumu kūʻai haʻahaʻa e loaʻa ai ka ʻae ʻana i ka mākeke wikiwiki, ʻaʻole hiki ke hoʻololi i ka palekana a me ka lōʻihi.Hoʻokumu nā mea hana kaulana i ka kūpaʻa kiʻekiʻe i ka palekana a me ka lōʻihi.
ʻO ka hapa nui o nā pākahi Li-ion kaʻana like me ka metala oxide positive electrode (cathode) i uhi ʻia ma luna o kahi ʻohi alumini o kēia manawa, kahi electrode maikaʻi ʻole (anode) i hana ʻia mai ke kalapona/graphite i uhi ʻia ma luna o kahi ʻohi keleawe o kēia manawa, kahi mea hoʻokaʻawale a me ka electrolyte. hana ʻia me ka paʻakai lithium i loko o kahi mea hoʻoheheʻe organik.ʻIke hou aku, pls e hele me teda battery.com.
Hōʻuluʻulu ka Papa 3 i nā pono a me nā palena o Li-ion.
