na kim Hoʻololi: Lulai 9, 2022

ʻO nā ʻona Li-ion he mau ʻona hiki ke hoʻopaʻa hou ʻia i loaʻa nā ion lithium. Hoʻohana ʻia lākou i nā mea āpau mai ke kelepona hele a i nā kaʻa. Akā pehea lākou e hana ai?

Hoʻohana nā ʻōhua Li-ion i kahi kaʻina intercalation e mālama i ka ikehu. Aia kēia kaʻina hana i nā ion lithium e neʻe ana ma waena o ka cathode a me ka anode i loko o ka pākaukau. I ka manawa hoʻouka, neʻe nā ion mai ka anode a i ka cathode, a i ka wā e hoʻokuʻu ai, neʻe lākou ma ka ʻaoʻao ʻē aʻe.

Akā, he ʻike pōkole wale nō ia. E nānā kākou i nā mea a pau i nā mea kiko'ī.

He aha ka Lithium-Ion Battery?

Aia nā ʻoni Lithium-ion ma nā wahi a pau i kēia mau lā! Mana lākou i kā mākou kelepona, laptops, nā kaʻa uila, a me nā mea hou aku. Akā, he aha lākou? E nānā pono kākou!

ke kumu o ke

Hoʻokahi a ʻoi aʻe paha nā kelepona, kahi papa kaapuni pale, a me kekahi mau mea ʻē aʻe:

• Nā Electrodes: ʻO nā hopena maikaʻi a hoʻopaʻa ʻole ʻia o ke kelepona. Hoʻopili ʻia i nā ʻohi o kēia manawa.
• Anode: ʻO ka electrode maikaʻi ʻole.
• Electrolyte: He wai a gel paha e hoʻokele i ka uila.
• ʻO nā mea hōʻiliʻili o kēia manawa: Nā pahu hoʻoheheʻe i kēlā me kēia electrode o ka pākaukau i hoʻopili ʻia i nā hopena o ke kelepona. Hoʻouna kēia mau pahu i ke au uila ma waena o ka pākaukau, ka mea hana, a me ke kumu ikehu e hoʻoikaika ai i ka pā.
• Separator: He kiʻiʻoniʻoni polymeric porous e hoʻokaʻawale i nā electrodes i ka wā e hiki ai ke hoʻololi i nā ion lithium mai kekahi ʻaoʻao a i kekahi.

No ke aha ka mea, na hana

Ke hoʻohana nei ʻoe i kahi hāmeʻa i hoʻohana ʻia e ka pā lithium-ion, ke neʻe nei nā ion lithium i loko o ka pā ma waena o ka anode a me ka cathode. I ka manawa like, ke neʻe nei nā electrons a puni i ke kaapuni waho. ʻO kēia neʻe ʻana o nā ion a me nā electrons ka mea e hana ai i ke au uila e hoʻoikaika i kāu hāmeʻa.

Ke hoʻokuʻu ʻia ka pākaukau, hoʻokuʻu ka anode i nā ion lithium i ka cathode, e hana ana i kahi kahe o nā electrons e kōkua i ka mana o kāu hāmeʻa. Ke hoʻopiʻi nei ka pākaukau, ʻokoʻa ka hopena: hoʻokuʻu ʻia nā ion lithium e ka cathode a loaʻa iā ia e ka anode.

Ma hea ʻoe e loaʻa ai iā lākou?

Aia nā ʻoni Lithium-ion ma nā wahi a pau i kēia mau lā! Hiki iā ʻoe ke loaʻa iā lākou ma nā kelepona, laptops, nā kaʻa uila, a me nā mea hou aku. No laila i ka manawa aʻe e hoʻohana ana ʻoe i kekahi o kāu mau mea punahele, e hoʻomanaʻo wale ʻia ua hoʻohana ʻia ia e ka pā lithium-ion!

Hōʻike pinepine ʻia kēia paepae ma ke ʻano he hiki ke nalowale a i ʻole ka piʻi ʻana o ka impedance. Hoʻohana maʻamau nā mea hana i ka huaʻōlelo "cycle life" e wehewehe i ke ola o kahi pākaukau ma ke ʻano o ka helu o nā pōʻaiapili e hiki ai i ka 80% o kona mana helu.

ʻO ka mālama ʻana i nā pākahi lithium-ion ma kahi kūlana i hoʻopiʻi ʻia e hōʻemi i ko lākou hiki a hoʻonui i ka pale ʻana o ke kelepona. ʻO ka mea nui kēia ma muli o ka ulu mau ʻana o ka pilina electrolyte paʻa ma ka anode. ʻO ke kaʻina ola holoʻokoʻa o kahi pākaukau, me ka pōʻaiapuni a me nā hana mālama mālama ʻole, ua kapa ʻia ʻo ke ola kalena.

Nā mea e pili ana i ke ola o ka pōʻaiapili

Hoʻopili ʻia ke ola pōʻaiapuni o kahi pākaukau e kekahi mau kumu, e like me:

• mahana
• Hoʻoheheʻe i kēia manawa
• Kauoha i kēia manawa
• Mokuʻāina o nā pae hoʻoili (hohonu o ka hoʻokuʻu ʻana)

Ma nā noi honua maoli, e like me nā smartphones, laptops a me nā kaʻa uila, ʻaʻole hoʻopiha piha a hoʻokuʻu ʻia nā pila. ʻO kēia ke kumu e alakaʻi hewa ai ka wehewehe ʻana i ke ola pākaukau ma nā ʻōlelo o nā pōʻai hoʻokuʻu piha. No ka pale ʻana i kēia huikau, hoʻohana ka poʻe noiʻi i ka hoʻokuʻu kumulative, ʻo ia ka huina o ka uku (Ah) i hāʻawi ʻia e ka pākaukau i kona ola holoʻokoʻa a i ʻole nā ​​​​pōkole piha like.

Hoʻohaʻahaʻa ʻana i ka pākaukau

Hoʻohaʻahaʻa haʻahaʻa nā pākaukau i ko lākou ola ʻana, e alakaʻi ana i ka hiki ke hoʻemi ʻia a, i kekahi mau hihia, e hoʻohaʻahaʻa i ka uila kelepona hana. ʻO kēia ma muli o nā ʻano kemika a me nā hoʻololi mechanical i nā electrodes. ʻO ka hoʻohaʻahaʻa ʻana i ka wela, a ʻo ka nui o ka hoʻopiʻi ʻana e wikiwiki hoʻi i ka nalowale o ka hiki.

ʻO kekahi o nā kaʻina hana degradation maʻamau:

• ʻO ka hoʻemi ʻana i ka electrolyte carbonate organik ma ka anode, ka hopena i ka ulu ʻana o Solid Electrolyte Interface (SEI). Hoʻonui kēia i ka ohmic impedance a me ka hōʻemi ʻana i ka uku Ah cyclable.

• Lithium metal plating, ka mea e alakaʻi ai i ka nalowale o ka lithium inventory (cyclable Ah charge) a me ka pōkole pōkole kūloko.

• ʻO ka hoʻomāinoino ʻana i ka uila: Ka hoʻonui ʻana a i ʻole ke kaapuni pōkole waho
• ʻO ka hana hoʻomāinoino mīkini: Ke komo a hāʻule paha
• Kaapuni pōkole i loko: Hana hewa a ʻelemakule paha

He aha ka mea e hiki ke hana?

ʻOi aku ke koʻikoʻi o ka hoʻāʻo ʻana no nā pā lithium-ion ma mua o nā ʻeke wai-electrolyte. Ua kau ʻia nā palena hoʻouna e nā mea hoʻoponopono palekana.

I kekahi mau hihia, pono nā hui e hoʻomanaʻo i nā huahana ma muli o nā pilikia pili i ka pākaukau, e like me ka Samsung Galaxy Note 7 hoʻomanaʻo i ka makahiki 2016.

Ke hoʻomaka nei nā papahana noiʻi e hoʻomohala i nā electrolytes non-flammable e hōʻemi i nā pōʻino ahi.

Inā hōʻino ʻia nā pākaukau lithium-ion, ʻeha, a hoʻokau ʻia paha i kahi haʻahaʻa uila kiʻekiʻe me ka pale ʻole o ka overcharge, a laila hiki mai nā pilikia. ʻO ka hoʻopili pōkole ʻana i kahi pākaukau hiki ke hoʻomāhuahua a wela paha ke ahi.

Li-Ion Battery Vs Lipo

I ka hiki ʻana mai i nā ʻāpana Li-ion vs LiPo, he kaua ia o nā titans. He mea maikaʻi loa nā pila Li-ion, e hoʻopili ana i hoʻokahi tona o ka ikehu i loko o kahi pūʻolo liʻiliʻi. Akā, hiki iā lākou ke paʻa ʻole a me ka pōʻino inā ua haki ka pale ma waena o nā electrodes maikaʻi a maikaʻi ʻole. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka palekana o nā pākahi LiPo, no ka mea ʻaʻole lākou e ʻeha i ka pilikia like o ka puhi ʻana. ʻAʻole lākou e ʻeha i ka 'hopena hoʻomanaʻo' e hana ʻia e nā pā Li-ion, ʻo ia hoʻi hiki ke hoʻonui hou ʻia i nā manawa me ka nalowale ʻole o ko lākou hiki. ʻOi aku, ʻoi aku ka lōʻihi o ke ola ma mua o nā pākahi Li-ion, no laila ʻaʻole pono ʻoe e hopohopo e hoʻololi pinepine iā lākou. No laila, inā ʻoe e ʻimi nei i kahi pākaukau palekana, hilinaʻi, a lōʻihi hoʻi, ʻo LiPo ke ala e hele ai!

Nā Bateri Li-Ion Vs Lead Acid

ʻOi aku ka liʻiliʻi o nā ʻakika ʻakika alakaʻi ma mua o nā pākahi lithium-ion, akā ʻaʻole lākou e hana like. Hiki ke hoʻopaʻa ʻia nā ʻakika waikawa alakaʻi a hiki i 10 mau hola, ʻoiai hiki ke hoʻopaʻa ʻia nā pākahi lithium ion i loko o kekahi mau minuke. ʻO ia no ka mea hiki i nā pākahi lithium ion ke ʻae i ka wikiwiki o kēia manawa, ʻoi aku ka wikiwiki o ka hoʻopaʻa ʻana ma mua o nā ʻeke waikona alakaʻi. No laila inā ʻoe e ʻimi nei i kahi pākaukau e hoʻopiʻi wikiwiki a maikaʻi hoʻi, ʻo ka lithium ion ke ala e hele ai. Akā inā ʻoe ma kahi kālā, ʻoi aku ka maʻalahi o ka waika lead.

Ua like anei ka pākahi Li-ion me ka lithium?

ʻAʻole, ʻaʻole like nā pākahi Li-ion a me nā pā lithium! ʻO nā pākahi liʻiliʻi nā pūnaewele mua, ʻo ia hoʻi ʻaʻole hiki ke hoʻouka hou ʻia. No laila, ke hoʻohana ʻoe iā lākou, ua pau. Ma ka ʻaoʻao ʻē aʻe, ʻo nā ʻāpana Li-ion nā ʻāpana lua, ʻo ia ka mea hiki ke hoʻopiha hou ʻia a hoʻohana hou ʻia. Eia kekahi, ʻoi aku ke kumukūʻai o nā pā Li-ion a ʻoi aku ka lōʻihi o ka hana ʻana ma mua o nā pā lithium. No laila, inā ʻoe e ʻimi nei i kahi pākaukau hiki ke hoʻopiha hou ʻia, ʻo Li-ion ke ala e hele ai. Akā inā makemake ʻoe i kahi mea ʻoi aku ka liʻiliʻi a lōʻihi ka lōʻihi, ʻo ka lithium kāu koho maikaʻi loa.

Pono ʻoe i kahi loina kūikawā no nā pā lithium?

ʻAʻole, ʻaʻole pono ʻoe i kahi loina kūikawā no nā pā lithium! Me nā pākahi lithium iTechworld, ʻaʻole pono ʻoe e hoʻomaikaʻi i kāu ʻōnaehana hoʻopihapiha holoʻokoʻa a hoʻolilo i ke kālā keu. ʻO nā mea āu e makemake ai, ʻo ia kāu mea hoʻopiha wai kēpau i kēia manawa a maikaʻi ʻoe e hele. Loaʻa i kā mākou mau pākahi lithium kahi Pūnaehana Hoʻokele Baterya kūikawā (BMS) e hōʻoiaʻiʻo i ka hoʻopiʻi pono ʻana o kāu pākaukau me kāu kauā.
ʻO ka charger wale nō ʻaʻole mākou e manaʻo e hoʻohana, ʻo ia ka mea i hoʻolālā ʻia no nā pākahi calcium. ʻO ia no ka mea ʻoi aku ka kiʻekiʻe o ka hoʻokomo uila ma mua o ka mea i manaʻo ʻia no nā ʻenekini hohonu hohonu lithium. Mai hopohopo, inā e hoʻohana wale ʻoe i ka pahu calcium, e ʻike ka BMS i ka volta kiʻekiʻe a hele i ke ʻano palekana, e pale ana i kāu pākaukau mai nā pōʻino. No laila, mai uhaʻi i ka panakō ke kūʻai aku i kahi loina kūikawā - e hoʻohana wale i kāu mea i loaʻa a hoʻonohonoho ʻia ʻoe!

ʻEhia ka lōʻihi o ke ola o kahi pākaukau lithium-ion?

ʻO nā pākahi Lithium-ion ka mana ma hope o kāu mau hāmeʻa i kēlā me kēia lā. Akā, pehea ka lōʻihi o lākou? Pono, pono e mau ka awelika o ka pākaukau lithium-ion ma waena o 300 a me 500 mau manawa hoʻoiho / hoʻokuʻu. Ua like ia me ka hoʻouka ʻana i kāu kelepona i hoʻokahi manawa i ka lā no hoʻokahi makahiki! Eia kekahi, ʻaʻole pono ʻoe e hopohopo e pili ana i nā pilikia hoʻomanaʻo e like me kāu ma mua. E mālama wale i kāu pākaukau a maʻalili a maikaʻi ʻoe e hele. No laila, inā mālama pono ʻoe iā ia, pono e hoʻopaʻa maikaʻi kāu pākaukau lithium-ion iā ʻoe.

He aha ka hemahema nui o ka pākaukau Li-ion?

ʻO ka haʻahaʻa nui o nā pākahi Li-ion ko lākou kumukūʻai. Aia lākou ma kahi o 40% ʻoi aku ka maikaʻi ma mua o Ni-Cd, no laila inā ʻoe ma kahi kālā, makemake paha ʻoe e nānā i kahi ʻē aʻe. Eia kekahi, hiki iā lākou ke ʻelemakule, ʻo ia hoʻi, hiki iā lākou ke nalowale i ka hiki a hāʻule ma hope o kekahi mau makahiki. ʻAʻohe kanaka i loaʻa ka manawa no kēlā! No laila, inā ʻoe e hoʻokomo i ka Li-ion, e ʻike pono ʻoe e hana i kāu noiʻi a loaʻa i ka bang maikaʻi loa no kāu kālā.

I ka hopena, he ʻenehana hoʻololi ʻo Li-ion i kā mākou mau mea hana i kēlā me kēia lā, mai nā kelepona paʻalima a i nā kaʻa uila. Me ka ʻike kūpono, hiki ke hoʻohana pono ʻia kēia mau pākahi me ka maikaʻi, no laila, mai makaʻu ʻoe e lawe i ka plunge a e ʻimi i ka honua o nā pākahi Li-ion!

Aloha ʻoe, ʻo wau ʻo Kim, he makuahine a he mea hoihoi hoʻi me ka ʻike i ka hana ʻana i ka media a me ka hoʻomohala pūnaewele. Nui koʻu makemake i ke kaha kiʻi a me ka hoʻoulu ʻana, a ke luʻu mua nei au i ka honua hoʻomaha. Me kaʻu blog, ke kaʻana nei au i kaʻu mau ʻike me ʻoukou.
