Menene bambanci tsakanin baturin lithium da baturin gubar acid?

Baturin lithium ion yana nufin baturi na biyu wanda Li+ ɗin da aka saka a ciki yana da inganci kuma mara kyau.

Ana amfani da mahadi Lithium LiXCoO2, LiXNiO2 ko LiXMnO2 a cikin ingantacciyar lantarki.

Lithium – carbon interlaminar fili ana amfani da LiXC6 a cikin mummunan lantarki.

Ana narkar da Electrolyte tare da gishiri lithium LiPF6, LiAsF6 da sauran hanyoyin maganin.

A cikin tsarin caji da fitarwa, Li+ yana ciki kuma an cire shi baya da baya tsakanin na'urorin lantarki guda biyu, wanda ake kira "rocking chair baturi".Lokacin cajin baturi, ana cire Li+ daga ingantacciyar wutar lantarki kuma a saka shi cikin madaidaicin lantarki ta hanyar lantarki, wanda ke cikin yanayin arzikin lithium.Akasin haka shine gaskiya lokacin fitarwa.

Kuma yanayin batirin gubar-acid shine: makamashin sinadarai zuwa na'urar makamashin lantarki da ake kira batir mai sinadari, wanda aka fi sani da batirin gubar-acid.Bayan fitarwa, ana iya sake caji don sake haɓaka abubuwan da ke aiki na ciki - adana makamashin lantarki azaman makamashin sinadarai;Ana canza makamashin sinadarai zuwa makamashin lantarki kuma lokacin da ake buƙatar fitarwa.Waɗannan batura ana kiran su Battery Storage, wanda kuma aka sani da batirin sakandare.Abin da ake kira baturin gubar-acid wani nau'in kayan aikin lantarki ne wanda ke adana makamashin sinadarai kuma yana fitar da wutar lantarki idan ya cancanta.

2, aikin aminci ya bambanta

Baturin lithium:

Lithium baturi daga cathode abu kwanciyar hankali da kuma abin dogara aminci zane, lithium baƙin ƙarfe phosphate baturi ya kasance tsananin aminci gwajin, ko da a cikin wani tashin hankali karo ba zai fashe, lithium baƙin ƙarfe phosphate thermal kwanciyar hankali ne high, electrolytic ruwa oxygen ikon ne low, don haka high aminci.(Amma gajeriyar kewayawa ko fashe diaphragm na cikin gida na iya haifar da wuta ko lalata)

Batirin gubar-acid:

Batirin gubar-acid zai fitar da iskar gas yayin caji da fitarwa ko amfani.Idan an toshe ramin shaye-shaye, zai haifar da fashewar tushen iskar gas.Ruwan da ke cikin ciki shine sputtering electrolyte (dilute sulfuric acid), wanda ruwa ne mai lalacewa, mai lalacewa ga abubuwa da yawa, kuma iskar gas da aka samar a cikin aikin caji zai fashe.

3. Farashin daban-daban

Baturin lithium:

Batirin lithium suna da tsada.Batir lithium sun fi batir-acid dalma tsada kusan sau uku.Haɗe tare da nazarin rayuwar sabis, farashin saka hannun jari ɗaya ne har yanzu tsawon rayuwar batirin lithium.

Batirin gubar-acid:

Farashin batirin gubar-acid ya tashi daga ƴan ɗari zuwa yuan dubu da yawa, kuma farashin kowane masana'anta kusan iri ɗaya ne.

4, kare muhalli iri-iri

Kayan baturi na Lithium ba tare da wani abu mai guba da cutarwa ba, ana ɗaukarsa azaman koren kare muhalli a duniya, baturin ba shi da ƙazanta a duka samarwa da amfani, daidai da ƙa'idodin RoHS na Turai, batir kare muhalli.

Akwai gubar dalma da yawa a cikin batirin gubar-acid, wanda zai gurɓata muhalli idan an zubar da shi ba daidai ba.

5. Rayuwar zagayowar hidima

Batirin lithium-ion yana daɗe fiye da batirin gubar-acid.Yawan sake zagayowar batirin lithium gabaɗaya yana kusan sau 2000-3000.

Batirin gubar-acid suna da kewayawa kusan 300-500.

6. Nauyin makamashi yawa

Yawan kuzarin batirin lithium gabaɗaya yana cikin kewayon 200 ~ 260Wh / g, kuma baturin lithium shine sau 3 ~ 5 na gubar, wanda ke nufin batirin gubar shine sau 3 ~ 5 na batirin lithium tare da ƙarfin iri ɗaya. .Saboda haka, baturin lithium ya mamaye cikakkiyar fa'ida a cikin nauyin haske na na'urar ajiyar makamashi.

Batirin gubar-acid gabaɗaya suna daga 50 wh/g zuwa 70wh/g, tare da ƙarancin ƙarfin kuzari kuma suna da girma sosai.

7. Ƙarfin ƙarfi

Batirin lithium-ion yawanci suna da girma kusan sau 1.5 fiye da na batirin gubar-acid, don haka sun kai kusan kashi 30 cikin 100 fiye da batirin gubar don ƙarfin iri ɗaya.

8. Yanayin zafin jiki daban-daban

Matsakaicin zafin baturi na lithium shine -20-60 digiri Celsius, kuma zafin zafi na baturin phosphate na lithium baƙin ƙarfe zai iya kaiwa 350 ~ 500 digiri Celsius, kuma har yanzu yana iya sakin ƙarfin 100% a babban zafin jiki.

Matsakaicin yanayin aiki na al'ada na baturin gubar-acid shine -5 zuwa 45 digiri Celsius.Don kowane raguwar digiri 1 a zafin jiki, ƙarfin dangi na baturin yana raguwa da kusan kashi 0.8.
