Pehea e hoʻomākaukau ai i nā pākahi lithium ion wela haʻahaʻa haʻahaʻa hiki ke hana maʻamau ma ka emi o 60°C?

I kēia mau lā, ua hoʻohana ʻo Ding Jianning o ke Kulanui ʻo Jiangsu a me nā mea ʻē aʻe i ka lithium iron phosphate coated mesoporous carbon ma ke ʻano he mea electrode maikaʻi a me kahi mea kalapona paʻakikī i waiwai i ka hale mesoporous i hoʻomākaukau ʻia e ka ʻenehana electrospinning ma ke ʻano he mea electrode maikaʻi ʻole. Lithium bistrifluoromethanesulfonimide LiTFSi paʻakai a me ka electrolyte o DIOX (1,3-dioxane) + EC (ethylene carbonate) + VC (vinylidene carbonate) nā mea hoʻoheheʻe i hui pū ʻia i loko o kahi pākaukau lithium-ion. ʻO nā mea pākaukau o ka pākaukau o ka mea i hana ʻia he mau hiʻohiʻona hoʻoili ion maikaʻi loa a me nā hiʻohiʻona desolvation wikiwiki o nā ion lithium, a me kahi electrolyte haʻahaʻa haʻahaʻa e mālama ana i ka hana maikaʻi ma nā haʻahaʻa haʻahaʻa, e hōʻoiaʻiʻo ana e hiki ke hana maʻamau ka pākaukau ma ka emi 60 °. C.

ʻOiai ʻo ka ʻenehana wikiwiki loa i ka ʻoihana pākaukau, hoʻokipa nui ka lehulehu i nā pā lithium-ion no kā lākou hana kiʻekiʻe kiʻekiʻe, kiʻekiʻe o ka ikehu, lōʻihi ke ola pōʻai, haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻohe hopena hoʻomanaʻo, a me ka "'ōmaʻomaʻo" palekana kaiapuni. Ua hoʻolilo nui ka ʻoihana i ka noiʻi. Nui nā noiʻi e pili ana i nā ion lithium hiki ke hoʻololi i nā mahana haʻahaʻa haʻahaʻa. Eia nō naʻe, ma lalo o nā wahi haʻahaʻa haʻahaʻa, e piʻi nui ka viscosity o ka electrolyte, a e hoʻolōʻihi i ka neʻe ʻana o nā pā lithium-ion ma waena o nā mea electrode. Eia kekahi, e maikaʻi ka electrolyte i nā haʻahaʻa haʻahaʻa. ʻO ka papa SEI i hoʻokumu ʻia i loko o ka electrode maikaʻi ʻole e hoʻololi i ka pae a lilo i mea paʻa ʻole. No laila, ʻo nā mea electrode maikaʻi a maikaʻi ʻole i ka mea i hana ʻia i kēia manawa e hāʻawi i kahi kaiapuni hoʻokumu SEI ʻoi aku ka paʻa, kahi mamao hoʻouna pōkole, a me kahi electrolyte me kahi haʻahaʻa haʻahaʻa haʻahaʻa i nā haʻahaʻa haʻahaʻa, e ʻike ana i kahi pākahi lithium hiki ke hana i kahi mahana ultra-haʻahaʻa. o ka emi o 60°C. . ʻO ka pilikia ʻenehana e hoʻoholo ʻia e ka mea i hana ʻia, ʻo ia ka lanakila ʻana i ka palena o ka noi ʻana o nā mea pākaukau lithium i nā wahi haʻahaʻa haʻahaʻa a me ka pilikia o ka viscosity kiʻekiʻe o nā electrolytes maʻamau i ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa ion mobility, a hāʻawi i kahi kiʻekiʻe kiʻekiʻe. a me ka hoʻokuʻu ʻana i ka wela haʻahaʻa ʻO ka pā lithium-ion a me ke ʻano hoʻomākaukau o ia mea e hoʻohana i ka pā lithium-ion e hoʻokō ai i ka hana maikaʻi loa a me ka hoʻokuʻu ʻana i nā haʻahaʻa haʻahaʻa.

Kiʻi 1 Hoʻohālikelike o ka hana electrochemical o nā pākahi lithium-ion haʻahaʻa wela ma ka lumi wela a me ka wela haʻahaʻa.

ʻO ka hopena maikaʻi o ka mea i hana ʻia ʻo ia ke hoʻohana ʻia ka mea electrode pōʻino ma ke ʻano he pepa electrode, ʻaʻohe mea paʻa. ʻAʻole ia e hōʻemi i ka conductivity, a e hoʻonui i ka wikiwiki o ka hana.
