Bateri y'amashanyarazi yitwa umutima w'ikinyabiziga cy'amashanyarazi; Ikirango, ibikoresho, ubushobozi, imikorere yumutekano, nibindi bya bateri yimodoka yamashanyarazi byahindutse "ibipimo" byingenzi na "ibipimo" byo gupima imodoka yamashanyarazi. Kugeza ubu, bateri igura ibinyabiziga by'amashanyarazi muri rusange 30% -40% by'imodoka yose, ishobora kuvugwa ko ari ibikoresho byingenzi!
Kugeza ubu, batteri nini nini ikoreshwa mu modoka z'amashanyarazi ku isoko muri rusange zigabanijwemo ubwoko bubiri: bateri ya ternary na baterium na lithium forphate. Ibikurikira, reka mpiseke muri make itandukaniro nibyiza nibibi bya bateri zombi:
1. Ibikoresho bitandukanye:
Impamvu yitwa "Ternary Lithium" na "lithium forphate" cyane cyane yerekeza kubintu bya "ibintu byiza bya electrode" yimbaraga;
"Ternary Lithium":
Ibikoresho bya Cathode bikoresha lithium nikel cobalt mangante (li (nicsorn) o2) ibikoresho bya ternary ibikoresho bya ternary kuri bateri ya lithuum. Ibi bikoresho bihuza ibyiza bya lithium coabant oxide, lithium nikel oxide na lithium mangate, gukora ibyiciro bitatu byerekana ibyiciro bitatu. Kubera ingaruka za ternary, imikorere yuzuye iruta iyo ari yo yose ihungabana.
"Lithium forphate":
bivuga batteri-ion ion bateri ukoresheje lithium frosphate nkibikoresho bya cathode. Ibiranga nuko bitarimo ibintu byicyuma nka coabant, igiciro cyibintu fatizo ni bike, kandi umutungo wa fosifore nicyuma ni byinshi kwisi, ntabwo rero bizagira ikibazo.
Incamake
Ibikoresho bya ternary ni bike kandi birazamuka hamwe niterambere ryihuse ryibinyabiziga byamashanyarazi. Ibiciro byabo ni byinshi kandi birabujijwe cyane nibikoresho fatizo. Ibi biranga lithium ya ternary kuri uhari;
Lithium Crowhate, kuko ikoresha igipimo cyo hasi cyibyuma / agaciro kadasanzwe kandi ni icyuma gihendutse cyane kandi kidahendutse kuruta bateri ya ternary kandi ntizihinduka ibikoresho fatizo. Ibi biraranga.
2. Ubucucike butandukanye:
"Bateri ya Ternary Lithim": Bitewe no gukoresha ibintu byinshi bikora, ubucucike bwingufu bwa bateri ya ternary lithium muri rusange (140h / kg ~ 160~180 wh / kg); Inguvu zimwe na zimwe zishobora kugera 180hw - 240h / kg.
"Lithium icyuma": Ubucucike bw'ingufu muri rusange 90-110 w / kg; Bamwe bashya lithium firm fosphate bateri, nka bateri ya blade, bafite imbaraga zingufu zigera kuri 120w / kg-140w / kg.
Incamake
Inyungu nini ya "bateri ya ternary lithim" hejuru ya "lithium icyuma" ni umuvuduko mwinshi wingufu hamwe numuvuduko wihuse.
3. Ibisobanuro bitandukanye byabapfura:
Kurwanya ubushyuhe buke:
Batiriyoni ya Ternary: Bateri ya Ternary Lithim ifite imikorere yubushyuhe buhebuje kandi irashobora kubika hafi 70% ~ 80% yubushobozi bwa batiri isanzwe kuri -20°C.
Lithium Crowhate: Ntabwo arwanya ubushyuhe buke: Iyo ubushyuhe buri munsi -10°C,
lithium icyuma cya litphate cyangirika cyangirika vuba. Lithium icyuma cya litphate birashobora kubungabunga hafi 50% kugeza 60% yubushobozi bwa batiri isanzwe kuri -20°C.
Incamake
Hano hari itandukaniro rinini mubushyuhe bwabahanga hagati ya "ternary lithim" na "lithium fosphate"; "Lithium Frosphate" irahanganye cyane n'ubushyuhe bwo hejuru; Kandi bateri yubushyuhe-bukabije "bwa ternary lithim" ifite ubuzima bwiza bwa bateri mu majyaruguru cyangwa imbeho.
4. Ubuzima Bwubuzima butandukanye:
Niba ubushobozi busigaye / ubushobozi bwambere = 80% ikoreshwa nkicyiciro cyanyuma, ikizamini:
Lithium Iron fosphate ya batiri ya bateri ifite ubuzima burema kuruta bateri-acide na bateri ya ternary. "Ubuzima burebire" bwa bateri-yashyizwe ku modoka yashyizwe ku modoka isobanura ibipimo bigera kuri 300 gusa; Bateri ya ternary irashobora kuba intangiriro zigera ku 2000, ariko muburyo nyabwo, ubushobozi buzabora kugeza kuri 60% nyuma yinshuro zigera ku 1.000; Kandi ubuzima nyabwo bwa lithium fosphate fosphate ni inshuro 2000, muri iki gihe, kandi ubuzima bwabwo bugera kuri 3000 bugera inshuro zirenga 3000.
Incamake
Batteri yimbaraga nipine yikoranabuhanga rya bateries. Ubwoko bwombi bwa bateri yumutima buramba. Utugaragaze, ubuzima bwa ternary ya bateri ya ternary ni 2000 yo kwishyuza no gusohoka. Nubwo twakwishyuza rimwe kumunsi, irashobora kumara imyaka irenga 5.
5. Ibiciro biratandukanye:
Kuva Lithium Frosphate bateri ya fotophate ntabwo irimo ibikoresho byicyuma, ikiguzi cyibikoresho fatizo birashobora kugabanuka cyane. Batteri ya ternary ikoresha lithium nikel cobalt mangate nkibishushanyo byiza bya electrode hamwe nibikoresho byiza cyane, bityo ikiguzi gihenze kuruta bateri yicyuma.
Bateri ya ternary lithim ikoresha cyane cyane ibikoresho bya ternary ya "lithium nikel cobanate" cyangwa "lithium nikel coalt, nka electrode nziza, cyane cyane ukoresheje umunyu mwiza, umunyu wa mangane nkibikoresho fatizo. "COBABAL EREGE" Muri ibi bikoresho byombi bya Cathode nicyuma cyagaciro. Dukurikije amakuru ava kurubuga rwibanze, igiciro cyimbere mu gihugu cyicyuma cya Coballat ni 413.000 Yuan / toni, kandi hamwe no kugabanya ibikoresho, igiciro gikomeje kuzamuka. Kugeza ubu, ikiguzi cya bateri ya ternary ni 0.85-1 yuan / wh, kandi ubu iratera imbaraga ku isoko; Igiciro cya Lithium Frosphate bateri zitarimo ibintu byicyuma birimo 0.58-0.6 yuan / wh.
Incamake
Kubera ko "lithium icyuma" ntabwo kirimo imiyoboro y'agaciro nka codabt, igiciro cyacyo ni inshuro 0.5-0-7.7 inshuro zose za bateriimie; Igiciro gihenze nicyiza kinini cya lithium forphate.
Incamake
Impamvu yatumye imodoka z'amashanyarazi zateye imbere mumyaka yashize kandi zihagarariye icyerekezo kizaza cyiterambere ryimodoka, guha abaguzi uburambe bwiza, ahanini biterwa no guteza imbere tekinoroji ya bateri yubuhanga.
