ʻO ka pilahi lithium wela welae pili ana i ke kiʻekiʻe o ka wela lithium-ion, no laila inā pahū i ka wā o ka hoʻohana ʻana, he aha ka hopena i ka pā? Ua ʻike mākou ʻo ke kelepona ʻo ia ka mea maʻamau lithium ternary. A i kēia manawa he nui nā pūnaewele like ʻole, e like me kekahi o kā mākou mau pahu lithium ternary maʻamau i hoʻohana i ka graphite negative electrode, ʻo kēia ʻano mea no ka electrode maikaʻi ʻole, hoʻohana ʻia nā pākahi lithium primera lithium cobaltate mea no ka electrode maikaʻi. No laila e pahū ana ka pākaukau lithium wela ma lalo o ka mahana wela mau? Maanei e kaʻana like me ʻoe i nā manaʻo pili.
E like me nā mea i hoʻohana ʻia i loko o nā pūnaewele pākaukau o kēia manawa, ʻo ia hoʻi nā pākahi lithium-ion ternary he lithium cobaltate, lithium iron phosphate a me nā mea ʻē aʻe e hana i ka electrode maikaʻi. No laila, ʻoi aku ka liʻiliʻi o ka pā lithium i ka haʻahaʻa haʻahaʻa i ka wā liʻiliʻi loa ka pahū. Akā ʻo ka hapa nui o ka mākeke o kēia manawa no nā pā lithium wela ākea e hoʻohana i ka lithium cobaltate e like me ka electrode maikaʻi. A hoʻokumu ʻia ka lithium iron phosphate ma ka ternary lithium e hana i kahi electrode maikaʻi ʻole; a ʻo ka lithium cobaltate e hana i kahi electrode maikaʻi; a ʻo ka lithium ion ternary e hana i kahi electrode maikaʻi ʻole ma mua o kahi electrode maikaʻi. Ke alakaʻi nei kēia i ka hoʻololi ʻana i kāna ʻano pākaukau.
No ka hoʻoponopono ʻana i ka pilikia palekana o nā pā lithium wela ākea, ʻo ke kī ke hoʻomaikaʻi i ka palekana. ʻO ka mea mua, pono e hoʻopaʻa pono ʻia ke kelepona pākaukau, ʻo ia hoʻi ka mea e hōʻoiaʻiʻo ai i ka hana ʻana o ka pākaukau a hiki ke pale maikaʻi i ke kaapuni pōkole kūloko a i ʻole overcharge i ka wā o ka hana ʻana o ka pākaukau, a me ka pale ʻana i ka hiki ʻana mai o ka wela kūloko kiʻekiʻe o ka pā. , ka hopena i ka pahū pākaukau. A i ka hoʻohana ʻana i kēlā me kēia lā, pono e hoʻolohe i ke ola palekana o ka pākaukau a pale i ka wela o ka pākaukau, ka hoʻouka ʻana a me nā kūlana ʻē aʻe. A laila, pono mākou e hoʻolohe i ka hopena o ka mahana ma luna o ka pā. ʻOi aku ka kiʻekiʻe o ka mahana pākaukau no ka palekana o ko mākou ola ponoʻī. No laila, inā makemake nā huahana pākaukau e hoʻohana maikaʻi ʻia i ko mākou ola i kēlā me kēia lā, pono mākou e hoʻolohe i ka hana hoʻomalu wela o ka pākaukau.
Mai ka ʻaoʻao palekana, ke kiʻekiʻe loa ka mahana o ka pākaukau, hiki i nā pākahi lithium-ion ke hana i kahi hanana hoʻopau wela. ʻO kēia no ka mea, ʻo ka lithium ion i loko o ka pā lithium-ion ka nui o nā kulu wai, ʻoi aku ka nui o ka wai, ʻoi aku ka kiʻekiʻe o ka mahana o ka pā lithium-ion, inā ʻo ka lithium ion i ka electrolyte excessive migration, diffusion e hana i ka. lithium ion irreversible migration e alakaʻi ana i ka puʻupuʻu puʻupuʻu pōkole pōkole, etc.. Eia kekahi, ʻo ka pākaukau i loko o ka manawa lōʻihi o ka hoʻomau ʻana i ka hana wela kiʻekiʻe ke kumu e hoʻoheheʻe ʻia nā mea pākaukau a me ka emi ʻana o ka hana, pēlā e hoʻonui ai i ke kaapuni pōkole e alakaʻi ana i loko. ke ahi a pahū paha. No laila, mai kahi manaʻo palekana, pono e hoʻopau ʻia ka hoʻohana ʻana i nā pākahi lithium-ion kiʻekiʻe i ka manawa kūpono. Eia kekahi, inā he kiʻekiʻe loa ka mahana, hiki ke maʻalahi ke hana i ka pōkole o loko a no laila ke kumu o ke ahi a me ka pahū. Eia kekahi, mai ka ʻike palekana o ka pā uila, inā ʻaʻole kahi nānā palekana piha a me ka hoʻohana ʻana i ke kūlana holo wela o ka pā lithium-ion e pahū paha.
ʻO kaʻoiaʻiʻo,ʻoi aku ka maikaʻi o ka hoʻohanaʻana i ka pāhana lithium wela nui no ka mea e hoʻokō ana i nā koi palekana o nā pahu lithium-ion i ka GB18483-2001 Safety Technical Specification for Lithium-ion Batteries, kahi iʻoi aku i ka laina me nā kūlana palekana. Akā, no ka mea he huahana hou ia, ʻaʻohe ʻano kūlana ʻāina a me nā kūlana ʻoihana e alakaʻi i ka hoʻomohala ʻana o kēia ʻenehana, no laila pono mākou e hoʻohui i ka hoʻohana ʻana i ka ʻike kikoʻī. I ke kaʻina hana pono e pale aku i ka pilina me ka wela kiʻekiʻe, ka uila static, ma luna o ka hoʻokuʻu ʻana, hoʻokuʻu a me nā mea pilikia ʻē aʻe, i ʻole e maʻalahi ke kumu o ka pahū kumu. No laila, i ka hoʻohana ʻana i kēlā me kēia lā, pono e hoʻolohe i ka hoʻohana palekana ʻana i nā pā lithium wela ākea a me ka mālama palekana a me ka hoʻohana.
ʻO ka mea i luna nei e pili ana i ka pahū ʻana o ka pā lithium wela ākea a me nā ʻike pili i ka pā lithium wela ākea.
