ʻO 18650 lithium-ion e hoʻopiʻi ana i nā haʻahaʻa haʻahaʻa he aha ke ʻano o ka hopena?E nānā kākou ma lalo.
He aha ka hopena o ka hoʻopaʻa ʻana i ka pā lithium-ion 18650 i ke kaiapuni haʻahaʻa haʻahaʻa?
ʻO ka hoʻouka ʻana i nā pākahi lithium-ion i nā kaiapuni haʻahaʻa haʻahaʻa ke kau nei i kekahi mau pilikia palekana.ʻO kēia no ka mea me ka hoʻohaʻahaʻa ʻana o ka haʻahaʻa, nā waiwai kinetic o ka graphite negative electrode e holomua ana i ka deterioration i ka manawa hoʻopiʻi, ʻo ka polarization electrochemical o ka electrode maikaʻi ʻole e hoʻonui nui ʻia, ʻo ka ua o ka metala lithium e hiki ke hoʻokumu i ka lithium. dendrites, hoʻopaʻa i ka diaphragm a pēlā e hoʻokaʻawale ai i nā electrodes maikaʻi a maikaʻi ʻole.E like me ka hiki ke pale aku i ka hoʻouka ʻana o ka pā lithium-ion i nā haʻahaʻa haʻahaʻa.
Ke noʻonoʻo nei i ka haʻahaʻa haʻahaʻa, ʻo ka electrode maikaʻi ʻole ma ka pā lithium-ion nested e ʻike ʻia i nā kristal ion, hiki ke hou i ka diaphragm, ma lalo o nā kūlana maʻamau e hoʻopilikia i ke ola a me ka hana, ʻoi aku ka nui o ka pahū!
Wahi a ka noiʻi loea mana: ʻo nā pākahi lithium-ion no kahi manawa pōkole i kahi wahi haʻahaʻa haʻahaʻa, a i ʻole ka lōʻihi o ka mahana mai ka haʻahaʻa, e hoʻopilikia wale i ka mana o nā pā lithium-ion, akā ʻaʻole ia e hana i ka pōʻino mau loa. .Akā inā hoʻohana ʻia no ka manawa lōʻihi i kahi kaiapuni haʻahaʻa haʻahaʻa, a i ʻole -40 ℃ ultra-low temperature environment, hiki ke hoʻopaʻa ʻia nā pā lithium-ion i mea e pōʻino mau ai.
ʻO ka hoʻohana haʻahaʻa haʻahaʻa o nā pā lithium-ion e loaʻa i ka haʻahaʻa haʻahaʻa, ka pohō nui, ka maikaʻi ʻole o ka hoʻonui ʻana i ka pōʻaiapili, ka haʻi ʻana o ka ua lithium, a me ka de-embedding lithium ʻole.Eia nō naʻe, me ka hoʻomau mau ʻana o nā mea hoʻohana nui, ʻo nā mea paʻa i lawe ʻia e ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā pā lithium-ion e lilo a maopopo loa.I loko o ka aerospace kaumaha, hana kaumaha, nā kaʻa uila a me nā kahua ʻē aʻe, pono e hana pono ka pākaukau ma -40°C.No laila, ʻo ka hoʻomaikaʻi mau ʻana o nā waiwai haʻahaʻa haʻahaʻa o nā pā lithium-ion he koʻikoʻi koʻikoʻi.
ʻae nō hoʻi,inā hoʻolako ʻia kāu pākaukau lithium 18650 me nā haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke hoʻopaʻa ʻia ma ke ʻano maʻamau i kahi wahi haʻahaʻa haʻahaʻa.
