Maganin makamashi na sabon ƙarni: 18650-70C batirin sodium-ion baturi ya zarce baturin LiFePO4 na gargajiya a cikin aiki

A taron kasa da kasa na makamashi mai dorewa da aka gudanar a yau, batirin sodium-ion mai suna 18650-70C ya ja hankalin mahalarta taron. Baturin ya zarce fasahar baturi na lithium iron phosphate (LiFePO4) da ake da shi a cikin maɓalli masu mahimmanci da yawa kuma ana ɗaukarsa a matsayin babban ci gaba a fagen sabunta makamashi.

Ayyukan batir sodium-ion ya yi fice musamman a ƙarƙashin matsanancin ƙarancin yanayin zafi. Zazzabi na fitar da shi zai iya kaiwa kasa da digiri 40 ma'aunin celcius, wanda ya fi dacewa da yanayin sanyi fiye da rage ma'aunin ma'aunin Celsius 30 na batirin LiFePO4. Wani abin da ya fi daukar hankali shi ne, yawan cajin (3C) na wannan baturin sodium-ion ya ninka na batirin LiFePO4 (1C) sau uku, kuma adadin fitar (35C) ya ninka na karshen (1C) sau 35. Ƙarƙashin yanayin fitar da bugun bugun jini mai nauyi, matsakaicin adadin fitar da bugun bugun jini (70C) ya kusan sau 70 na batirin LiFePO4 (1C), yana nuna yuwuwar yin aiki.

Bugu da kari, ana iya fitar da batir sodium-ion gaba daya zuwa 0V ba tare da lalata rayuwar batir ba, wanda ke da matukar muhimmanci ga tsawaita rayuwar batir. Dangane da ajiyar kayan, batirin sodium-ion suna amfani da albarkatu masu yawa kuma marasa iyaka, wanda ke nufin cewa a kan sikelin duniya, batir sodium-ion za su fi araha ta fuskar samarwa da farashi fiye da batir LiFePO4, waɗanda ke da ƙarancin albarkatun lithium. Amfani.

Dangane da ingantaccen aikin aminci, an ayyana wannan baturin a matsayin “mafi aminci”, kuma kodayake ana ɗaukar batir LiFePO4 a matsayin nau'in baturi mai aminci, idan aka kwatanta da sabbin batir sodium-ion, ƙarshen yana da aminci a fili.

Wannan ci gaban fasaha yana ba da sabbin hanyoyin samar da wutar lantarki ga motocin lantarki, na'urorin tafi da gidanka, da kuma manyan tsarin ajiyar makamashi, kuma ana tsammanin zai haifar da manyan canje-canje a kasuwar ajiyar makamashi ta duniya.

Yayin da canjin makamashi ke ci gaba da zurfafawa, nasarorin da aka samu a sabbin fasahohin batir sun bude kofa ga ingantacciyar rayuwa, mai kore, da dorewa nan gaba.
