ʻO ka pākaukau lithium-ion maʻalahi

Ua hoʻokumu kekahi pūʻulu o nā mea noiʻi ma ke Kulanui o Kaleponi i kahi holomua o ka ʻenehana pākaukau - kahi e hiki ai ke mālama ʻia ka mana nui i loko o nā ʻenekini maʻalahi a lahilahi.

Manaʻo ʻia kēia mau pākaukau e hoʻololi ʻaʻole wale i ka ʻenehana mea kūʻai aku akā nā mea lapaʻau pū kekahi. Hana ʻia lākou mai loko mai o ka lithium-ion, kahi e hoʻohālikelike ai i kāu pākaukau kelepona. ʻO ka ʻokoʻa hou, hiki iā lākou ke hoʻololi me ka haki ʻole. ʻO ia ka mea e hiki ai ke hoʻohana i nā mea uila hiki ke hoʻopili ʻia, e like me kekahi mau kelepona Samsung e hiki mai ana.

ʻAʻole liʻiliʻi paha kēia mau pila hou e hana i nā dendrites, ʻo ia hoʻi, lilo nā pilikia palekana i mea o ka wā ma mua. ʻO nā Dendrites ke kumu o ke ahi a me ka pahū ʻana - kahi mea e manaʻo ai nā hui ʻenehana āpau e pale i ka mea hiki. Hoʻokumu ʻia nā dendrites e like me ka hoʻopiʻi ʻana a me ka hoʻokuʻu ʻana. Inā ulu lākou e hoʻopā i nā ʻāpana metala ʻē aʻe o ka pākaukau, a laila hiki ke hele mai kahi kaapuni pōkole e hiki ai ke pahū a i ke ahi paha.

ʻAʻole maopopo i ka poʻe ʻepekema pehea ka lōʻihi o ka hele ʻana mai ka prototype a i ka huahana kalepa, akā ʻike mākou e ʻoi aku ka palekana o kēia mau pākahi lithium-ion hou ma mua o kā mākou i kēia manawa - a ʻoi aku ka lōʻihi. Ua paʻi ʻia ka ʻike ma ka puke pai ʻo ACS Nano.

Pono e hoʻomaopopo ʻia ua ʻike nā kānaka ʻepekema ma ke Kulanui ʻo Stanford a me MIT i kēia pilikia like i kekahi mau makahiki i hala aku nei, e hōʻike ana i nā mea ʻoʻoleʻa hiki ke hoʻololi i loko o kahi pākaukau i ka wā o ke kaʻa kaʻa (ka hoʻouka / hoʻokuʻu ʻana). ʻOiai he maikaʻi no ka ʻenehana mea kūʻai aku, he mea pōʻino kēia no nā mea lapaʻau no ka mea ʻo ka hapa nui i hana ʻia me ka silicone (ʻo ia ka mea maʻalahi loa). Pono paha nā lāʻau lapaʻau maʻalahi e hoʻāʻo hou e hōʻoia i ka palekana.

Manaʻo ʻia ka ikaika o nā pākahi hou ma mua o nā pā lithium-ion i loaʻa, ʻoiai ʻaʻole maopopo inā he ʻoiaʻiʻo kēia no nā noi āpau. Ua ʻike ʻia e maʻalahi loa nā pākaukau a hiki ke kulou i nā ʻano he nui me ka haki ʻole. Wahi a ka hui noiʻi, hiki i hoʻokahi gram o kā lākou mea hou ke mālama i ka ikehu e like me ka pākaukau AA, akā pono mākou e kali a ʻike i nā ʻoihana e hana me kēia ʻenehana ma mua o ka ʻike maopopo ʻana.

Panina

Ua hana ka poʻe noiʻi i nā pākahi lithium-ion paʻakikī, maʻalahi a liʻiliʻi paha e hana i nā dendrites. Manaʻo lākou e hoʻohana ʻia kēia mau pihi i nā kelepona hiki ke hoʻopili ʻia, nā mea lapaʻau a me nā ʻenehana ʻē aʻe. ʻAʻole ʻike ʻia ka lōʻihi o ka hele ʻana o kēia mau pākahi mai ka prototype a i ka huahana ma ka mākeke.

Ua hana ʻia ka ʻenehana hou ma UC Berkeley a paʻi ʻia ma ka puke pai ACS Nano. Ua ʻike ʻia e nā ʻepekema ma Stanford University a me MIT i kekahi mau makahiki i hala. Ua hōʻike ʻia kēlā noiʻi ʻana hiki i nā mea ʻoʻoleʻa ke hoʻololi i loko o kahi pākaukau i ka wā o ke kaʻa uila (ka hoʻouka ʻana a me ka hoʻokuʻu ʻana). He mea pōʻino kēia mau ʻike no nā lāʻau lapaʻau, i hana ʻia ma waho o ka silicone. Pono nā lāʻau lapaʻau maʻalahi e hoʻāʻo hou aʻe ma mua o ka ʻae ʻia a kūʻai nui ʻia paha.

ʻOi aku ka ikaika o kēia mau pākahi hou ma mua o nā ʻeke lithium-ion i loaʻa. ʻAʻole maopopo inā he ʻoiaʻiʻo kēia no nā noi āpau. Wahi a ka hui noiʻi, hiki i hoʻokahi gram o kā lākou mea hou ke mālama e like me ka pākahi AA, akā pono mākou e kali a ʻike i nā ʻoihana e hana me kēia ʻenehana ma mua o ka ʻike maopopo ʻana.
