Te Whakamātautau i te Rōhutu Hiko o te Lithium Teitei me ngā Rōhutu Tātai: He Whakamātautau

Te Kaha o te Hiko me te Whakamāhi i te Whānanga o te Rōhutu i te Ao Tūmati

He aha te take? te rōhutu hiko o te lithium e whakamānui ana ko te kaha o te hiko e whakawhitinga ana i te roa o te whakamāhi—ko tēnei anake i ngā hāngā e tika ana

Ko te kaha o te hiko—e whakamātua ana i ngā watt-āhua i te kilogram (Wh/kg)—e whakamārama ana i te rahinga o te hiko e whakamānui ana te rōhutu i tēnei, i tēnei hāngā ki tana mātātoko. Ko ngā rōhutu hiko o te lithium e whakamānui ana e whai ana i te 200–260 Wh/kg, he rahi atu noa i te 40–100 Wh/kg o ngā rōhutu alkaline. Arā, ko te lithium e whakamānui ana i te hiko nui atu i te wāhanga o te mātātoko— engari ko tēnei anake i te whakamāhi i te hāngā . I rākau māmā, kia tāwhai tonu (hei tauira, he kaitātai IoT e whakamātau ana i ia hōu), ko te lithium e tuku ana i te wāhi o tana uara āhua. I ngā tāwhai pūmau, he iti ake te hiko e whakamāhinga ana i te rere o te hiko mai i te whakawhitinga o roto—engari ko te iti ake o te whakawhitinga o roto o te lithium (30–80 mΩ) e whakamāmā ana i tēnei ngāwari. He tauira, he whakamāhinga pai ki ngā whakamāhinga o ngā kāmera matatau, me te iti o te pakaru o te wāhi, i te wā i ngā pīroiroi āhua e pakaru ana i ngā pīroiroi āhua. Ko te wā roa o te whakamāhinga e tātai ana kāore noa i te nui o te wāhi o te hiko, engari i te whakamārama o te whakamāhinga o te pīroiroi me te āhua o te whakamāhinga o te rākau.

Te rere o te hiko, te whakawhitinga o roto, me te whāinga o te rere o te whakamāhinga: Me pēhea ngā pīroiroi āhua e ngaro ai te wāhi o te hiko i te wāhi.

Ko ngā pī hiko aha kē he whakamātautau ake i te rōrahi o roto—150–300 mΩ i tēnei, i tēnā ko ngā pī hiko lithium-ion i te 30–80 mΩ—ā, he whakamātautau ake i te whakamātautau o te hiko i te wā o te whakamāhi. I te piki ake o te hāngā o te hiko, ka heke te hiko o te pūkoro i raro i te whakamātautau o te rārangi (hei tauira, 1.0 V/cell), ā, ka mutu te mahinga ahakoa kāore anō i whakamāhi ngā 30% o ngā hiko aha kē. Ko tēnei hiko kāore i whakamāhi he tohu o te whakamātautau ake o ngā pī hiko aha kē i te hāngā o te whakamāhi: i ngā whakamātautau i te whare pukenga, ka whakamāhi ngā pī hiko aha kē anō i te 50% o ngā hiko i whakamātautau i ngā hāngā o te hiko i te 500 mA, i tēnā ko ngā pī hiko lithium e whakamāhi ana i te 92%. Nō reira ngā pī hiko aha kē e hinga ana i mua i te wā i ngā taputapu hāngā nui pērā i ngā kāmera matatau, i ngā tāpoi motuhake, i ngā taputapu hāngā nui—ā, he nui ake te hāngā o te hiko i te whakamāhi i te hiko i te whakamāhi i ngā hiko i te whakamāhi i ngā hiko.

Te Whananga o te Hāngā Nui me te Whakamāhi i ngā Taputapu

Ngā kāmera matatau, ngā kaiwhakamātautau IoT, ngā taputapu rongoā hāere: Kei hea te whakamātautau ake o ngā pī hiko lithium hāere hāere me ngā hiko nui

He pūhanga hiko kaha o ngā pūhanga hiko kia tāwhai ai te wāhi, he rereke te whakamātautau i ngā āhuatanga pāpātahi—hei whakamārama mō ngā whakamātau e hiahiatia ana te hiko pāpātahi me te whakamātautau. Ko ngā kāmera matatau e herea ana ki te rereke o te hiko hei whakamātautau i te whakamātautau tāwhai, i te whakamātautau whakaahua, me ngā whakamātautau o te whakamātautau; ko ngā whakamātautau hiko o ngā whakamātautau hiko e herea ana ki ngā whakamātautau hiko pāpātahi, pāpātahi i ngā whakamātautau hiko o te ora; ā, ko ngā whakamātautau IoT o ngā whakamātautau hiko e herea ana ki te whakamātautau pāpātahi i ngā whakamātautau hiko pāpātahi, pāpātahi i ngā whakamātautau hiko pāpātahi. Ko te iti o te whakamātautau o te lithium (15–30 mΩ) e whakamātautau ana i te whakamātautau, e whakamātautau ana i te whakamātautau i te katoa o te whakamātautau. I ngā whakamātautau hiko pāpātahi, ko tēnei whakamātautau e whakamātautau ana i te wā o te whakamātautau ake i te 40% i ngā whakamātautau alkaline, NiMH.

Ngā rerekētanga o ngā pūhanga hiko alkaline i ngā whakamātautau hiko pāpātahi: te whakamātautau o te whakamātautau me ngā whakamātautau o te whakamātautau

Ko ngā pī hiko aha kē he rerekē i ngā whakamātautau pūhanga, i tō rātou teitei o te whakawhitinga o roto me te pōuri o te nekeneke o ngā iona. I te wā e whakamātauria ana i ngā tāpiri pūhanga pūpahi, pērā i ngā taputapu hiko, ngā kōwhiringa rorohiko rānei, ka hinga tonu te hāngā o te pī hiko, ā, ka whakamātua ngā whakamātua i mua i te wā, ahakoa kāore anō i te 30% o te pūhanga e wātea ana. Rere kē i te lithium, i taea ai te whakarewa i ngā pūhanga pūpahi, ko ngā pī hiko aha kē he rerekē i ngā pūhanga pūpahi me ngā whakamātua kāore i te tika, ā, he rerekē hoki i ngā mahi e here ana i te wā. I rere mai i ngā whakamātautau pūhanga e whakamāna ana i UL 1451, ka ngaro ngā pī hiko aha kē i te hāngā o rātou i te 50% i raro i ngā pūhanga pūpahi 500 mA—i te wā i tāwhai ai ngā pī hiko lithium i te >90%. Ko ēnei rerekē he take mō ngā whakakapi kāore i te hāngā, ngā wā tāwhai, me ngā utu roa i ngā wāhi taupua me ngā wāhi tāpoi.

Te roa o te ora, te utu totora o te whakamāhi, me te whakaora o te taiao

Te ora o te whakamāhi, te pāhua o te tau, me te tātai utu totora: ngā pī hiko lithium whakamāhia anō vs ngā pī hiko aha kē kāore i te whakamāhia anō i te 2 tau me ngā tau e whai mai ana

I te whakamahinga i te wā roa, ko te utu o te whakamahi i te wāhi katoa (TCO) he tāwhai ake i ngā pīhanga rerehua hauāngā lithium ātaahua. Ko tēnei pīhanga lithium tēnā i tēnei, e 500–1,000 ngā whakamātau i mua i tana pā ki te 80% o tōna pūmau tuatahi, i te rā anō, ko ngā pīhanga alkaline he pīhanga takitahi anake. Ko te pānga o te wā hoki e whakarahi ake i tēnei rerekētanga: ko te whakamātautau ake o te lithium i te 2–5% i ia marama; ko te alkaline e ngaro ana i te 10–20% i ia marama—ākene anō i te wā kāore i te whakamahinga. I tēnei rā i tēnei rā i tēnei rā i ngā tau e rua, ko tēnei pīhanga lithium e whakakapi ana i ngā pīhanga alkaline e 50–100, i tēnei rā i tēnei rā. Ahakoa ko te utu tuatahi he toru ki te rima ngā wā ake, i te whakauru i ngā utu whakakapi, ngā utu hāere, ngā utu whakakore, me ngā wā kāore i te whakamahinga, ka pāpā ake te TCO i te 40–60%. Mō ngā rārangi hāngā e whai ana i te oranga—pērā i ngā rārangi whakamārama i wāhi pāpā, i ngā taputapu rongoā—ko tēnei e whakawhitinga ana i te whakapai ake o te wā o te whakamahi, me te iti ake o ngā utu whakamāhi.
