Ngā Tohu Matihiko o te Pūtauheke Rite Taurangi Whakaiti I whakaatu i te āhua

I te ao o ngā whakahaere taumaha o tenei rā, ko te hunga pūtētahi he mea hiranga nui e whai ake ana, ko te pūtētahi tāngata lifepo4 hiranga nui ka puta iho hei tūmomo whakaaro mō te whenua. Ki runga i ana huanga ā-tinana matua me ngā pūnaha hangarau e whai ake nei, kei a ia i hangaia ngā huarahi hou whakamua ki roto i ētahi atu rā.

Tirohanga matua mo ngā māteriale lithium iron phosphate

Ko te lithium iron phosphate (Lithium iron phosphate) he whakaaetanga kiko taketake, he whakarara olivine, e whai ana i te wharewhare tuarua, me te kīanga wāhi Pmnb. I te wa i kitea ai i te tau 1997, ka whakatika atu ki te tūmomo rangahau matua mo ngā māteriale paihou mo ngā pūtētahi ion lithium me ana huanga.

He kapenga mōhio taumata matua tuuturu tōna, e pāngia ana ki te 170 mA・h／g, he wehewehe anamata noa iho tōna umu wero mōhanga, i te taurunga 3.5V, he kauwhata porihanga whakawhiti hapa meihei, he haerenga pai o te werawera, ko te kino moana he iti rawa. ​​

Nga pai mataara o Pūtahi Hiko Rawa Ataata

Kupu hua nui​

I te whiuwhiu nui tūmomo hua kupu ka puta i te whakatika hiahia i te kupu hua. Ki ngā tau nei, mā te whakapai ā-momomo me te whakapai ā-tikanga, kua whakaiti i a ia tana kupu hua. Ko tenei kupu hua nui e hīnātia nei, e hoki ana i te take huarahi i te wā e rite ana rānei te rahi, kia whakamahia ai te kaha motuhake mo te tūranga. ​

Kawe pai whakamahere atawhai​

Ko te kawe atawhai mahere atawhai he atea tuatahitia enei. Pūtahi Hiko Rawa Ataata .

I raro i te whakangungu o te poutere pai, ka whakamahi i te hunga poutere super electron mo te whakapakoko holoiti ki ngā whenua e taea ana te whanaketanga nano o te whenua poutere lithium iron phosphate me te hanga i tetahi tūmomo super electron, e whakaiti ana i te whawhai ki te wehe i te lithium ion, ā, e whai kaha ana ki te whakahautanga o te pātengi.

I raro i te whai hou i te whenua pūnaha, ka whakamahi i te hunga whakarerekē ion tuarua hou ki te whakatika i te mata o te grafa, ki te whakapai i ngā rāhui kaiwhakawhiu me te poto i te heke, pērā i te hanga i tētahi 'mōhio' mō te whakawhanake ion.

I raro i te whakawhanake i te elektrolite, ka hanga i tētahi tohu elektrolite whakawhanaketanga whakahirahira hoki hei whakaiti i te kokoritanga o te elektrolite, me te whakapai nui i te whakawhanaketanga. Ki runga anō, ka whakatika i te whirokore SEI ko te kotahi rawa i te whakaiti i te whawhai whakawhanake.

Tērā pea, i whakapai ake ngā raraunga o te kōwhiringa matatū nui me te itinga he iti o te mīhini whakawehenga, kia whai wāhi ake te āhuatanga o te kawe i ngā iraka lithium. Ko te whakamahi poroiti o ēnei momo hangarau e mahi nei i runga i te pūtake tūmomo, ka hoki haere te pūtaketanga o te whakawehenga ki te here kaha lifepo4 i runga i ngā pūtahi here pakino kē.

Pono tonu ki te haumanu

Ko te pono tonu ki te haumanu he mea nui i roto i ngā whakamahinga pūtahi, ko ngā pūtahi here kaha lifepo4 kei te pai rawa i roto i tēnei take.

Ka whakamahia ana he gene elektorita whakapai hei whangai i te werawera e puta mai i ngā kaiwhakaaroaro rīpora-tūtae. Tērā pea, ko te whiuwhiu kōwhatu tonu ki te pūtahi, ko te hunga o taua whiuwhiu ko te itinga he iti o te werawera me te mana motuhake nui ki te whakarite i te werawera, e tiaki ana i te pono tonu ki te haumanu o te pūtahi i te taumata here.

Āhei hoki, mā ngā algoritama iti whakaaro ki te whakahaere i te horopaki ohu matua me te hanga i tētahi reta whakamatau atawhai i rānei, ka taea te tirohia me te whakatika i ngā pūnaha haumaru e taea ana, whakarite i ngā raruraru haumaru nui e tuhono nei i runga i te kawe āhua waihanga ki te takutai. Mēnā ka noho wehe ngā tahuhu o te paenga me te waewae o te pūtake, kaore i whakaeke ki te puru rānei ki te whārangi, whakapakari i te taunakitanga moeoneone mō ngā whakamahi.

Ko DHC kei te hanga i te whenua o te wai kaihau whakaoranga i waenganui i ngā tekau tau ake, ā, kei te whakahaere i ngā whakaaetanga kaihau me ngā whakaaetanga moeoneone mō ngā whenua o te ao. Ki te he koe i ngā pātai mō ngā pūtake moeoneone, kia kitea ai au ki ahau.
