Kumukūʻai pākaukau maʻalahi

He ʻenehana hou loa nā ʻenekini maʻalahi, a ma muli o ka hopena, ua pilikia mua lākou i nā kumukūʻai kiʻekiʻe. Eia naʻe, ua kōkua ka holomua o ka ʻenehana i ka hoʻohaʻahaʻa ʻana i nā kumukūʻai me ka hoʻomaikaʻi ʻana i ka maikaʻi. Ke hoʻomau nei kēia mau pila i ka kaulana, pono e hāʻule nui ko lākou kumukūʻai. He mau makahiki ma mua o ka lilo ʻana o nā wati maʻalahi no nā mea uila haʻahaʻa haʻahaʻa loa e like me $10 wati, akā maʻalahi ke noʻonoʻo ʻana ʻo ke kumu kūʻai maʻamau o nā wati kikohoʻe i kekahi lā ma lalo o $50 no lākou.

ʻOiaʻiʻo, ua lohe au aia kekahi poʻe i hana mua i nā ʻenekini maʻalahi no ka haʻahaʻa o $3. ʻAʻole hiki ke ʻike inā he ʻoiaʻiʻo kēlā mau ʻōlelo, akā ʻaʻohe nīnau e hāʻule ka ʻenehana i ke kumukūʻai i nā makahiki e hiki mai ana. I kēia manawa, ʻike ʻia ka hapa nui o ke kumukūʻai mai nā mea waiwai a me ka hana ʻana ma mua o ka noiʻi a me ka hoʻomohala ʻana. Inā hoʻomau kēia ʻano, manaʻo mākou e ʻike i ka hāʻule ʻana o nā kumukūʻai i ka wā e piʻi ai ka hana i nā pae kiʻekiʻe. ʻOliʻoli wau i nā ʻenekini maʻalahi ma muli o ko lākou manaʻo no ka hana ʻana i nā mea hiki ke hoʻopili ʻia i loko o nā lole a i ʻole nā ​​​​mea hiki ke hoʻohana ʻia me ka hoʻohui ʻole ʻana i ke kaumaha a i ʻole ka nui.

Ua kamaʻilio liʻiliʻi ʻia nā pākiki maʻalahi ma muli o ko lākou hoʻohana ʻana i nā mea ʻenehana kiʻekiʻe. Hoʻohana ʻia ka ʻenehana i nā mea e like me iPhones a me nā drones, kahi i alakaʻi ai i ka piʻi nui o ka ʻike lehulehu. ʻOiai ua puni kēia mau pila no kekahi manawa, me he mea lā ke hoʻomaka nei lākou e lawe ʻia e ka mākeke mea kūʻai nui. Ke hana nei kēia, pono mākou e ʻike i nā ʻoihana hou e hoʻoholo ana e hoʻohana iā lākou ma muli o nā pono e like me ke kumukūʻai a me ka hiki.

Loaʻa i nā pākiki maʻalahi i kēia manawa, akā hiki ke hoʻoholo ʻia ka hapa nui o ia mau mea me ka noiʻi hou a me ka hoʻomohala ʻana. ʻO ka ʻoiaʻiʻo, ʻaʻohe mea hōʻike ʻaʻole e hoʻohālikelike a ʻoi aku paha i ka nui o ka ikehu o nā ʻenehana pākaukau e like me Li-On cell. Inā loaʻa kēlā, ʻike koke ʻoe iā ʻoe iho e kūʻai aku i kahi pahu kelepona ʻoi aku ka lahilahi e pale ai i kahi pākaukau ma mua o ka pākaukau e hoʻoikaika i kāu kelepona. He mea maikaʻi kēia no ka mea hiki iā ʻoe ke loaʻa kahi pahu liʻiliʻi a maʻalahi ma mua o kahi pahu nui a i ʻole ka pākaukau ʻokoʻa.

Pīhoihoi au i ka ʻike ʻana ua hoʻohana ka hapa nui o nā ʻanuʻu maʻalahi e like me ka lithium a me ka graphite ma ke ʻano he anode a me nā mea cathode. Aia kekahi mau mea kemika hou i hui pū ʻia me ia mau mea ʻelua, akā pili ka hopena i ka hopena i nā pila i kēia manawa a ʻoi aku ka nui o ke kālā. ʻO ka ʻoiaʻiʻo, ʻike ʻia nā kumukūʻai maka no nā ʻokoʻa maʻalahi me nā cell Li-On ʻoiai hiki iā lākou ke mālama i ko lākou ʻano ma mua o ka hoʻohana ʻana i nā hihia paʻa. Hiki paha ke hoʻololi hou aku i kēia koena, akā ʻike maopopo ʻia ʻaʻole kēia mau pākahi i nā mea waiwai a me nā mea ʻē aʻe a ka poʻe i hopohopo ai.

Me he mea lā ʻo nā paʻakikī nui loa e kū nei i nā pākiki maʻalahi i kēia manawa ke hoʻonui nei i ka hana a me ka hoʻonui ʻana i nā ola pōʻai. ʻAʻole maʻalahi kēia mau pilikia e hoʻoponopono, akā me he mea lā e ʻike mākou i ka holomua ma kēia mau ʻaoʻao ʻelua i nā makahiki e hiki mai ana. Hiki nō hoʻi ke loaʻa nā holomua i nā ʻenehana pākaukau ʻē aʻe e lele ai ma luna o nā ʻenekini maʻalahi inā ʻoi aku ka maikaʻi ma mua o kā mākou i kēia lā. No ka laʻana, ʻoi aku ka maikaʻi o nā supercapacitors i hoʻokumu ʻia i ka graphene ma mua o nā kelepona Li-On maʻamau a i ʻole nā ​​pākaukau maʻalahi. Eia nō naʻe, ʻaʻole hiki i ka graphene ke hoʻohālikelike i ka nui o ka ikehu o nā ʻano pākaukau i kēia manawa no laila ʻaʻole ia he hoʻohālikelike apple-to-apples inā ua hana.
