ʻO wai ka kaʻa uwila maikaʻi loa, pākaukau lead-acid, graphene battery, a i ʻole pākahi lithium?

I kēia manawa ua lilo nā kaʻa uila i mea pono loa no ka lawe ʻana i ko mākou ola i kēlā me kēia lā, ʻo wai ka pākaukau ʻoi aku ka maikaʻi loa no nā kaʻa uila, nā ʻakika lead-acid, nā pihi graphene, a me nā pā lithium? E kamaʻilio kākou e pili ana i kēia kumuhana i kēia lā. ʻO ka pākaukau kekahi o nā mea pono o nā kaʻa uila. Inā makemake ʻoe e ʻike i ka mea o nā ʻino ʻekolu i ʻoi aku ka maikaʻi, pono ʻoe e hoʻomaopopo i nā pono a me nā pōʻino o kēia mau pākahiko ʻekolu. ʻO ka mea mua, e hoʻomaopopo i ka pākaukau lead-acid, graphene battery, a me ka lithium battery.

ʻO ka pākaukau lead-acid kahi pākaukau mālama nona nā electrodes maikaʻi a maikaʻi ʻole i hoʻokumu ʻia me ke alakaʻi dioxide, ke alakaʻi a me ka dilute sulfuric acid electrolyte me ka nui o ka 1.28 ma ke ʻano waena. Ke hoʻokuʻu ʻia kahi pākaukau lead-acid, ʻelua ke alakaʻi dioxide ma ka electrode maikaʻi a me ke alakaʻi ma ka electrode maikaʻi ʻole me ka dilute sulfuric acid e hana i ke alakaʻi sulfate; i ka wā e hoʻouka ai, hoʻemi ʻia ke alakaʻi sulfate ma nā papa maikaʻi a maikaʻi ʻole i alakaʻi dioxide a me ke alakaʻi.

ʻO nā mea maikaʻi o nā pākaukau lead-acid: ʻO ka mea mua, he mea liʻiliʻi lākou, he haʻahaʻa nā kumukūʻai hana, a maʻalahi ke hana. Eia kekahi, hiki ke hana hou ʻia nā pākaukau i hoʻohana ʻia, hiki ke hoʻopau i kahi ʻāpana o ke kālā, e hōʻemi ana i ke kumu kūʻai o ka hoʻololi ʻana. ʻO ka lua ka hana palekana kiʻekiʻe, kūpaʻa maikaʻi loa, hoʻopiʻi lōʻihi, ʻaʻole e pahū. Hiki ke hoʻoponopono ʻia ke kolu, ʻo ia hoʻi, e wela ia i ka wā e hoʻopiʻi ana, a hiki iā ia ke hoʻohui i ka wai hoʻoponopono e hoʻonui i ka hiki ke mālama ʻia o ka pākaukau, ʻaʻole like me nā pā lithium, ʻaʻole hiki ke hoʻoponopono ma hope o kahi pilikia.

ʻO nā hemahema o nā pākī lead-acid he nui ka nui, kaumaha kaumaha, hiki ʻole ke neʻe, pōkole ke ola lawelawe, ka hoʻouka ʻana a me nā manawa hoʻokuʻu ma kahi o 300-400 mau manawa, a hiki ke hoʻohana maʻamau no 2-3 mau makahiki.

ʻO ka pākaukau ʻo Graphene kahi ʻano o ka pākaukau lead-acid; ʻo ia wale nō ka hoʻohui ʻia ʻana o nā mea graphene e pili ana i ka pākaukau lead-acid, ka mea e hoʻonui ai i ka pale ʻana i ka corrosion o ka pā electrode, a hiki ke mālama i ka uila a me ka mana ma mua o ka pākaukau lead-acid maʻamau. Nui, ʻaʻole maʻalahi e bulge, lōʻihi ke ola lawelawe.

ʻO kāna mau mea maikaʻi, i ka hoʻohui ʻana i nā pōmaikaʻi o nā pākī lead-acid, ma muli o ka hoʻohui ʻana o nā mea graphene, ʻoi aku ka lōʻihi o ke ola o ka lawelawe, hiki i ka helu o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana ke piʻi aku ma mua o 800, a ʻo ke ola lawelawe ma kahi o 3-5 mau makahiki. . Eia kekahi, hiki iā ia ke kākoʻo i ka hoʻopiʻi wikiwiki. ʻO ka mea maʻamau, hiki ke hoʻopiha piha ʻia ma kahi o 2 mau hola, ʻoi aku ka wikiwiki ma mua o nā pahu pahu lead-acid maʻamau i nā hola 6-8, akā pono e hoʻopiʻi ʻia me kahi loina hoʻolaʻa. He 15-20% kiʻekiʻe ke kiʻekiʻe o ka huakaʻi ma mua o nā pākī lead-acid maʻamau, ʻo ia hoʻi inā hiki iā ʻoe ke holo i 100 mau kilomita, hiki ke holo ka graphene ma kahi o 120 mau kilomita.

He mea koʻikoʻi nō hoʻi nā pōʻino o nā pila graphene i ka nui a me ke kaumaha. He paʻakikī lākou i ka lawe ʻana a me ka neʻe ʻana e like me nā pākaukau lead-acid maʻamau, ʻoi aku ka kiʻekiʻe.

Hoʻohana maʻamau nā pāʻani lithium i ka lithium cobaltate ma ke ʻano he mea electrode maikaʻi a me ka graphite kūlohelohe e like me ka electrode maikaʻi ʻole, me ka hoʻohana ʻana i nā hopena electrolyte non-aqueous.

ʻO nā mea maikaʻi o nā pākahi lithium he liʻiliʻi, hiki ke maʻalahi, a maʻalahi hoʻi e lawe, ke kiʻekiʻe kiʻekiʻe, ka lōʻihi o ke ola pākaukau, ke ola lōʻihi, a ʻo ka helu o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana hiki ke hiki i kahi 2000 mau manawa. ʻAʻole hiki ke hoʻohālikelike ʻia me ia i nā ʻakika lead-acid a i ʻole nā ​​pā graphene. ʻO ka hoʻohana ʻana i nā pākahi lithium ʻoi aku ka nui o nā makahiki ma mua o ʻelima mau makahiki.

ʻO nā hemahema o nā pākahi lithium he paʻa ʻole, lōʻihi ka manawa e hoʻopiʻi ai, a i ʻole ka hoʻohana pono ʻole, hiki ke kumu i ke ahi a i ʻole pahū. ʻO kekahi, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai ma mua o nā pākī lead-acid.

ʻO wai ka pākaukau lead-acid maikaʻi loa, graphene battery, a i ʻole lithium battery, a ʻo wai ka mea kūpono? He paʻakikī kēia e pane. Hiki iaʻu ke ʻōlelo aku ʻo ka mea kūpono iā ʻoe ka mea maikaʻi loa. E like me nā pono like ʻole o kēlā me kēia mea nona ka kaʻa, hiki iā ia ke hoʻohana i nā pila ʻē aʻe. No ka laʻana, inā makemake ʻoe e loaʻa ka lōʻihi o ke ola pākaukau. I kēlā hihia, hiki iā ʻoe ke noʻonoʻo i nā pākahi lithium. . Inā hoʻohana wale ʻia ka kaʻa uila no ka holo ʻana i kēlā me kēia lā, a laila lawa ke koho ʻana i nā ʻeke waiʻaila maʻamau. Inā lōʻihi ka hele ʻana, a laila hiki ke noʻonoʻo ʻia nā pā graphene. No laila, e like me kāu mau pono like ʻole, e noʻonoʻo i ke kumukūʻai o ka pākaukau, ke ola, a me ke ola pākaukau e koho i kahi pākaukau kūpono iā ʻoe. E ʻoluʻolu ʻoe e hōʻike i kou mau manaʻo ma ka wahi manaʻo a komo inā he ʻokoʻa kou manaʻo?
