Njira yothetsera mphamvu ya m'badwo watsopano: 18650-70C batri ya sodium-ion imaposa batri yachikhalidwe ya LiFePO4 pakugwira ntchito

Pamsonkhano wapadziko lonse wa Sustainable Energy Conference womwe wachitika lero, batire ya sodium-ion yotchedwa 18650-70C idakopa chidwi chambiri kuchokera kwa omwe adatenga nawo gawo. Batire imaposa ukadaulo wa batire wa lithiamu iron phosphate (LiFePO4) m'magawo ambiri ofunikira ndipo imatengedwa kuti ndi patsogolo kwambiri pazamphamvu zongowonjezwdwa.

Kugwira ntchito kwa mabatire a sodium-ion ndikwabwino kwambiri chifukwa cha kutentha kwambiri. Kutulutsa kwake kutentha kumatha kufika madigiri 40 osakwana 40 Celsius, omwe ndi abwino kwambiri kumadera ozizira kuposa mabatire osakwana 30 Celsius a LiFePO4. Chochititsa chidwi kwambiri ndi chakuti mtengo wamtengo wapatali (3C) wa batire iyi ya sodium-ion ndi yowirikiza katatu kuposa ya batire ya LiFePO4 (1C), ndipo kutulutsa (35C) ndi 35 kuwirikiza kawiri (1C). Pansi mkulu-katundu kugunda kumaliseche mikhalidwe, pazipita zimachitika kumaliseche mlingo (70C) ndi pafupifupi 70 nthawi ya LiFePO4 batire (1C), kusonyeza yaikulu ntchito kuthekera.

Kuphatikiza apo, mabatire a sodium-ion amatha kutulutsidwa kwathunthu ku 0V popanda kuwononga moyo wa batri, zomwe ndizofunikira kwambiri pakukulitsa moyo wa batri. Pankhani ya nkhokwe zakuthupi, mabatire a sodium-ion amagwiritsa ntchito zinthu zambiri komanso zopanda malire, zomwe zikutanthauza kuti padziko lonse lapansi, mabatire a sodium-ion adzakhala okwera mtengo kwambiri pogula ndi mtengo kuposa mabatire a LiFePO4, omwe ali ndi zinthu zochepa za lithiamu. Ubwino.

Poganizira kusintha kwachitetezo, batire iyi imanenedwa kuti ndi "yotetezeka", ndipo ngakhale mabatire a LiFePO4 akhala akudziwika kwambiri ngati mtundu wa batri otetezeka, poyerekeza ndi mabatire atsopano a sodium-ion, otsirizawa ndi otetezeka.

Kupambana kwaukadaulo kumeneku kumapereka mayankho amagetsi atsopano pamagalimoto amagetsi, zida zam'manja, ndi makina akuluakulu osungira mphamvu, ndipo akuyembekezeka kubweretsa kusintha kwakukulu pamsika wapadziko lonse lapansi wosungira mphamvu.

Pamene kusintha kwa mphamvu kukukulirakulira, kupita patsogolo kwa matekinoloje atsopano a batri kwatsegula chitseko cha tsogolo labwino, lobiriwira, komanso lokhazikika.
