Hana nā pila paʻa-kūlana ma ka hoʻohana ʻana i kahi electrolyte paʻa, ʻo ia ke kī i ka hoʻomaopopo ʻana pehea e hana ai ka pila paʻa. ʻAe kēia electrolyte paʻa i nā ion e neʻe pono ma waena o nā electrodes, e hoʻolilo ana i ka pila i palekana a hiki iā ia ke mālama i ka ikehu hou aku. No ka laʻana, he maikaʻi loa ka conductivity ionic o nā electrolytes paʻa i hoʻokumu ʻia i ka sulfide, me nā waiwai ma luna o 10^-2 S/cm. Hoʻomaka ka nui o ka ikehu o kēia mau pila ma 400–500 Wh/kg a hiki ke ʻoi aku ma mua o 1000 Wh/kg.

Nā Manaʻo Koʻikoʻi

• He electrolyte paʻa ko nā pila paʻa. Hoʻoneʻe kēia i nā ion me ka palekana a me ka wikiwiki. ʻOi aku ka palekana a me ka ikaika ma mua o nā pila maʻamau.

• ʻOi aku ka nui o ka ikehu o kēia mau pila. Hoʻopiʻi wikiwiki lākou a hana lōʻihi. Kōkua kēia i nā hāmeʻa e liʻiliʻi, māmā, a hilinaʻi ʻia.

• He mau pilikia nō ko nā pila paʻa. He nui ke kumukūʻai a he paʻakikī ke hana. Ke hana nei nā kānaka ʻepekema e hoʻoponopono i kēia mau pilikia. I ka wā koke, e hoʻohana paha nā kaʻa uila a me nā mea hana iā lākou.

He aha nā pila paʻa-kūlana?

Nā pila paʻa-kūlana he mea paʻa e hoʻoneʻe ai i nā ion. ʻAʻohe wai i loko o kēia mau pila. Hoʻohana lākou i nā mea e like me nā electrolytes sulfide-based a i ʻole nā ​​​​​​ʻāpana i uhi ʻia me ka maloʻo. ʻO kēia ka mea e palekana ai ka pila a ʻoi aku ka paʻa.

E nīnau paha ʻoe pehea ka ʻokoʻa o kēia mau pila mai nā mea i loko o kāu kelepona a kamepiula lawe paha. Hoʻohana nā pila lithium-ion maʻamau i kahi electrolyte wai. Hiki i kēia wai ke liki a puhi paha inā haki ka pila. ʻAʻohe pilikia o nā pila paʻa. ʻAʻole liki ka mea paʻa a hiki ke mālama maikaʻi i ka wela.

Eia kahi papa maʻalahi e hōʻike i nā ʻokoʻa nui:

Hiki i nā pila paʻa ke mālama i ka ikehu hou aʻe a lōʻihi ke ola. Hoʻohana nā kānaka ʻepekema i nā mea hana kūikawā a me nā hoʻāʻo e hōʻoia i ka hana maikaʻi o kēia mau pila a ʻoi aku ka palekana. Ke hoʻohana ʻoe i nā mea me nā pila paʻa, loaʻa iā ʻoe ka mana hou aʻe i loko o kahi pila liʻiliʻi a palekana.

Manaʻo kōkua: I ka holomua ʻana o ka ʻenehana, e ʻike ʻoe i nā pila paʻa i nā mea hou aku, e like me nā kelepona a me nā kaʻa uila.

Pehea ka hana ʻana o ka pila paʻa

He ʻokoʻa nā pila paʻa mai nā pila maʻamau. ʻEkolu mau ʻāpana nui o lākou: anode, cathode, a me ka electrolyte paʻa. Aia ka electrolyte paʻa ma waena o ka anode a me ka cathode. Hoʻokuʻu ia i nā ions e neʻe akā hoʻōki i nā electrons. Kōkua kēia i ka mālama ʻana i ka pila a hāʻawi i ka ikehu me ka palekana.

Ke hoʻouka ʻoe i ka pila, Haʻalele nā ​​​​ion lithium i ka cathode. Hele lākou ma o ka electrolyte paʻa i ka anode. Ke hoʻohana ʻoe i ka pila, hoʻi nā ion i ka cathode. ʻAe wale ka electrolyte paʻa i nā ion e neʻe. Pono nā electrons e hele ma o kahi uea ma waho o ka pila. ʻO kēia ka mea e hoʻoikaika ai i kāu mau hāmeʻa.

Hoʻāʻo nā kānaka ʻepekema i nā electrolytes paʻa like ʻole e ʻike i ka mea e hana maikaʻi loa. Hoʻohana lākou i nā mea waiwai i ka lithium e hana i ka electrolyte. Pehea lākou e hana ai e hoʻololi ai i ka wikiwiki o ka neʻe ʻana o nā ions. Hōʻike nā hoʻokolohua X-ray i ke ʻano e kōkua ana i nā ions e neʻe wikiwiki. Loaʻa i kekahi mau electrolytes paʻa ka conductivity ionic ma luna o 1 mS/cm. ʻO ke ʻano kēia e neʻe maikaʻi loa nā ions. Kōkua ka conductivity kiʻekiʻe i nā pila e hoʻopiha wikiwiki a lōʻihi.

E noʻonoʻo paha ʻoe pehea e hoʻohālikelike ʻia ai nā pila paʻa me nā pila lithium-ion. ʻO ka ʻokoʻa nui ka electrolyte. Hoʻohana nā pila Lithium-ion i kahi electrolyte wai. Hiki i kēia wai ke liki a puhi paha inā hōʻino ʻia. Hoʻohana nā pila paʻa i kahi electrolyte paʻa. ʻAʻole ia e liki a puhi maʻalahi paha. ʻOi aku ka palekana o kēia.

Nānā: ʻAʻole e wela nā electrolytes paʻa. Hoʻemi lākou i ka pilikia o ke ahi a me ka wela nui. ʻO kēia ka mea e maikaʻi ai nā pila paʻa no nā kaʻa uila a me ka mālama ikehu nui.

Eia kahi papa e hōʻike i nā ʻokoʻa palekana:

Hana maikaʻi nā pila paʻa ma nā ʻano he nui. Hāʻawi ka electrolyte paʻa i ka nui o ka ikehu. Loaʻa iā ʻoe ka mana hou aʻe i loko o kahi pila liʻiliʻi. ʻOi aku ka lōʻihi o ke ola o ka pila a ʻoi aku ka wikiwiki o ka hoʻopiʻi ʻana. Hōʻike nā hoʻokolohua ʻoi aku ka maikaʻi o ka neʻe ʻana o ka ion e hāʻawi i ka 98.9% o ka mana piha. Hiki i ka pono o ka ikehu ke hiki i 97.8%. ʻO ke ʻano kēia, emi ka ikehu i hoʻonele ʻia a loaʻa iā ʻoe ka hoʻohana hou aku mai kēlā me kēia hoʻopiʻi ʻana.

I kēia manawa ua ʻike ʻoe pehea e hana ai nā pila paʻa. He mea nui loa ka electrolyte paʻa. Hoʻokuʻu ia i nā ions e neʻe wikiwiki a palekana. Hoʻolilo pū ia i ka pila i palekana a ikaika hoʻi ma mua o nā pila kahiko. Ke aʻo hou aku ʻoe, e ʻike ʻoe i ke kumu he mea nui kēia ʻenehana no ka wā e hiki mai ana.

He aha nā ʻano o nā pila paʻa?

Nui nā ʻano pila paʻa. Hoʻohana kēlā me kēia ʻano i nā mea hana a me nā hoʻolālā like ʻole. Hoʻopilikia kēia mau hoʻololi i ke ʻano o ka hana ʻana o ka pila a me kahi e hoʻohana ʻia ai.

Hoʻokomo ʻia nā pila paʻa i ʻelua mau pūʻulu nui. Pili nā pūʻulu i ka mānoanoa o ka electrolyte.

• Nā pila paʻa paʻa nui he mau electrolytes mānoanoa. Hana ka poʻe iā lākou ma ke kaomi ʻana a i ʻole ka hoʻomehana ʻana i nā ʻāpana.

He aha nā hoʻohana o nā pila paʻa-mokuʻāina?

Nā noi a me nā pilikia

Hoʻohana ʻia nā pila paʻa-kūlana i nā kaʻa uila, nā kelepona akamai, a me nā kāleka akamai. No ka laʻana, hoʻohana ka sedan Nio ET7 i kahi pila semi-solid-state. Hiki iā ia ke hele i 650 mile ma ka hoʻouka hoʻokahi. Hiki i ka pila paʻa-kūlana a Samsung ke hele ma mua o 600 mile. Hiki iā ia ke hoʻouka a hiki i 80% i loko o ka emi ma mua o 10 mau minuke.

• ʻOi aku ka palekana o nā pila paʻa-kūlana a ʻoi aku ka lōʻihi o ke ola.

• Pono lākou i nā mea kūikawā a me ke kūkulu pono ʻana.

• He paʻakikī ke hoʻopaʻa kokoke i nā ʻāpana paʻa.

• Pono nā hale hana e mālama i ka wai, ʻoiai no nā pila e pili ana i ka sulfide.

E ʻike ʻoe i nā pila paʻa-kūlana hou aʻe i ko lākou emi ʻana o ke kumukūʻai. Ke holomua nei nā hale hana i ka hana ʻana iā lākou. I kēia manawa, ke nānā aku nei lākou he mea hoʻohiki maikaʻi loa akā aia nō kekahi mau pilikia e hoʻoponopono ai.

Pehea ka palekana o nā pila paʻa?

E noʻonoʻo paha ʻoe inā ʻoi aku ka palekana o nā pila paʻa ma mua o nā mea maʻamau. Hoʻohana kēia mau pila i kahi electrolyte paʻa. ʻAʻole e ʻā a liki paha kēia ʻāpana paʻa. Ma muli o kēia, ʻoi aku ka liʻiliʻi o ka hopena o ke ahi ma mua o nā pila me ka wai i loko. Hiki iā ʻoe ke palekana i ka hoʻohana ʻana i nā pila paʻa i nā mea e like me nā kaʻa a i ʻole nā ​​kelepona.

Akā, ʻaʻole wale ka palekana e pili ana i ke kāohi ʻana i ke ahi. Ua aʻo nā kānaka ʻepekema ma ke Kulanui ʻo Purdue i ka mea e hana ʻia ke hāʻule kēia mau pila. Ua ʻike lākou hiki i kekahi mau electrolytes paʻa, e like me Li10SnP2S12, ke wela loa. Hana ʻia kēia inā hoʻomaka kekahi mau hopena kemika ma ka anode. Hiki i kēia mau hopena ke hoʻomehana koke i ka pila. Hiki i ka wela ke hoʻokuʻu i ka cathode i ka oxygen. Hiki i kēia ke hana i nā hopena hou aʻe a me kahi mea i kapa ʻia ʻo "thermal runaway." No laila, ʻoiai ʻaʻole e ʻā nā ʻāpana paʻa, hiki i ka pila ke wela loa inā he pilikia i loko.

Hoʻohana nā kānaka ʻepekema i nā mea hana X-ray e nānā i loko o nā pila paʻa. Ua ʻike ka papahana SOLBAT a ka Faraday Institution hiki ke hana ʻia nā māwae i loko o ka electrolyte paʻa ma mua o ka hōʻiliʻili ʻana o ka lithium. Hiki i kēia mau māwae ke pālahalaha a hana i nā kaapuni pōkole. Inā hoʻohana nui ʻoe i ka pila, hiki ke hana ʻia nā hakahaka hakahaka. Hiki i ka Lithium ke ulu i loko o kēia mau hakahaka a hoʻolilo i ka pila i mea palekana ʻole.

Manaʻo kōkua: ʻOi aku ka palekana o nā pila paʻa ma mua o nā pila kahiko, akā pono ʻoe e makaʻala. ʻO nā hoʻolālā hou a me nā mea ʻoi aku ka maikaʻi e hoʻolilo iā lākou i mea palekana koke.

He aha nā pilikia i ka hoʻohana pono ʻana o nā pila paʻa?

Me he mea lā he maikaʻi nā pila paʻa, akā he mau pilikia ko lākou. He hana paʻakikī ko nā kānaka ʻepekema a me nā ʻenekinia e hoʻohana iā lākou i ke ola maoli. ʻAʻole maʻalahi ka hoʻohana ʻana i kēia mau pila i nā kaʻa a i ʻole nā ​​kelepona.

Eia kahi papa e hōʻike ana i nā pilikia nui:

He paʻakikī ka hana ʻana i nā pila paʻa. Pono e laumania nā papa a ʻaʻohe māwae. Inā nui a liʻiliʻi paha ka pila, hiki ke haki i loko. Hoʻolohi ka wā anuanu i ka neʻe ʻana o nā ion. Pono nā hale hana i nā mīkini kūikawā e kūkulu i kēia mau pila. ʻOi aku ke kumukūʻai o kēia.

Manaʻo kōkua: Ke hana nei nā kānaka ʻepekema e hoʻoponopono i kēia mau pilikia. Ke loaʻa iā lākou nā ala maikaʻi aʻe, e ʻike ʻoe i nā pila paʻa hou aʻe a puni ʻoe.

Āhea e hōʻea mai ai nā pila paʻa-mokuʻāina ma ka mākeke uila?

E noʻonoʻo paha ʻoe i ka wā e ʻike ai ʻoe nā pila paʻa i nā kaʻa uila a me nā mea hana ʻē aʻe. Hōʻike nā hōʻike loiloi mākeke e ulu wikiwiki ana ka mākeke pākahiko paʻa. I ka makahiki 2024, ʻo ka nui o ka mākeke ma kahi o $128.5 miliona. I ka makahiki 2032, manaʻo nā loea e hiki i $2,001.7 miliona. ʻO ke ʻano kēia e ulu paha ka mākeke ma mua o 40% i kēlā me kēia makahiki. Hiki iā ʻoe ke manaʻo e ʻike i nā pākahiko paʻa hou aʻe ma waena o 2025 a me 2032.

He nui nā mea e kōkua ai i kēia ulu ʻana. Ke piʻi mau nei ke kūʻai aku ʻana o nā kaʻa uila. Hāʻawi nā aupuni i nā mea hoʻoikaika e hoʻohana i ka ikehu maʻemaʻe. ʻOi aku ka maʻalahi o ka loaʻa ʻana o nā kikowaena hoʻouka. Hoʻolilo pū nā ʻoihana i ke kālā hou aku ma ka noiʻi a me ka hoʻomohala ʻana. Hana pū nā mea hana kaʻa nui a me nā ʻoihana pila e kūkulu i nā hale hana hou. Kōkua kēia mau ʻanuʻu i ka lawe ʻana mai i nā pila paʻa i ka mākeke me ka wikiwiki.

E ʻike paha ʻoe i nā pila paʻa mua i nā kaʻa uila kiʻekiʻe. ʻO nā ʻoihana ma ʻAmelika Hui Pū ʻIa, ʻEulopa, Kina, a me Iapana ke alakaʻi nei i ke ala. Ma hope o nā kaʻa hanohano, e ʻike paha ʻoe i kēia mau pila i nā kaʻa maʻamau, nā kaʻa ʻōhua, a me ka mālama ʻana i ka ikehu home.

Nānā: ʻAʻole paha ʻoe e ʻike koke i nā pila paʻa-kūlana i loko o kēlā me kēia kaʻa. I ka wā mua, e ʻoi aku ke kumukūʻai a aia i loko o nā hiʻohiʻona kūikawā. I ka hana ʻana o nā hale hana i nā mea hou aku, e hāʻule nā ​​​​kumukūʻai, a e ʻike ʻoe iā lākou ma nā wahi he nui.

Eia kahi nānā wikiwiki i ka mea e manaʻo ai:

E hiki koke mai ana nā pila paʻa. E ʻike ʻoe iā lākou e hoʻololi i ke ʻano o kāu hoʻohana ʻana i nā kaʻa uila a me nā mea hana ʻē aʻe i nā makahiki e hiki mai ana.

Ua aʻo ʻoe pehea e hana ai ka pila paʻa. Hoʻohana kēia mau pila i kahi electrolyte paʻa. Kōkua kēia i nā ions e neʻe palekana a wikiwiki. Eia kekahi mau mea maikaʻi nui e pili ana iā lākou:

Hiki i nā pila paʻa ke hoʻomaikaʻi i nā kaʻa uila a me nā mea hana no nā kānaka āpau.

Nā nīnau i nīnau pinepine ʻia

He aha ka mea e palekana ai nā pila paʻa-kūlana ma mua o nā pila maʻamau?

ʻOi aku ka palekana o nā pila paʻa-kūlana no ka mea ʻaʻole hiki i ka electrolyte paʻa ke liki. ʻAʻole hoʻi ia e wela. ʻO ke ʻano kēia, ʻoi aku ka haʻahaʻa o ka manawa o kāu mau hāmeʻa i nā ulia.
