He aha te hanganga o roto o te kete pākahiko lithium-ion haumaru? Ko nga kohinga pākahiko lithium-ion katoa ka puta mai i nga ngoikoretanga o te ara-poto, ka hua ki te overtilization, inaki, overcurrent, super pāmahana, me era atu, katoa i runga i te pākahiko lithium-ion hangahanga o roto. Ko nga taumata pai me te kino o te pākahiko lithium-ion kia noho ma, me te electrolyte pākahiko lithium-ion, me whakamaarama te diaphragm i te wa e whakaputa ana, engari kaore e taea te tiaki i te hiko hiko lithium katote me te diaphragm i roto i te puehu, te parahi Mooring ranei te konukawata konumohe, etc.

Ko te Lithium kaore i roto i te tono ngawari (te utu nui, te ngaro, te nui o te waa) ranei i te taiao tino taiao (te teitei rawa o te pāmahana), ka nui atu i te pāmahana, kei te whakakorehia te wahangu o te para i roto i te ahua o te pāmahana noa, na te mea kei roto i te wera Lithium-ion pākahiko electrolyte i roto i te waahi wera. Ka honoa, mena ka tata te toenga ki te diaphragm, ka kino te wera e tika ana ki te wehenga o te diaphragm, ka mutu ka rahua te ara iahiko poto. Na reira, he nui te polymer lithium electrolyte inaianei, ka whakakapi i te otinga electrolyte wai ki te otinga colloidal, ka taea te whakaiti i te tupono o te korenga o te waahi poto.

Ko te kaupapa o te putea hiko lithium-ion: ko te putea hiko lithium he papahiko tuarua (pēhiko rechargeable), me te matua ki te kaha o nga papahiko lithium-ion i te pokapū o te mahi, te whakaoti i te rokiroki me te tuku i te kaha o te hiko. I roto i te tukanga katoa o te utu pākahiko, ko te pākahiko katote lithium ka puta te taumata pai o te pākahiko rechargeable, me te pākahiko katote lithium na te hiko hiko katote lithium katoo ki te taumata kino. Ko te waro he hanganga-a-koeke kino, me te nui o te microplate, he pākahiko katote lithium kino i roto i te pereti moroiti o te waro, te nui ake o nga pākahiko lithium katote, te kaha o te pākahiko Ka nui ake.

Waihoki, i te wa e utaina ana te pākahiko rechargeable me te tuku, ka tangohia ano te pākahiko katote lithium i roto i te paparanga waro kino, ka hoki ano ki te taumata pai. Ko te nui ake o nga pākahiko lithium-ion ka whakahokia, ka nui ake te ruri; te maataapono taketake o te hanganga o te kete pākahiko katote lithium. 1, te hanga pai.

Hangaia te koranu mahara 4 (lithium iron phosphate) + kaihoko kawe (pango acetylene) + whakapiri (PVDF) + huinga wai (konukawata konukawata). 2, hanga kino. Ko te graphite parakore teitei + te kaihoko kawe (pango acetylene) + te whakapiri (PVDF) + te kino kino (parahi).

He pai te hanganga o te kete pākahiko katote rino phosphate i te wa e rere ana te lithium. .
