M'dziko losungirako mphamvu zomwe zikuyenda mwachangu, mitundu iwiri ya mabatire yakhala ikupanga mitu yankhani:Mabatire a sodium-ion (SIBs)ndiMabatire a Lithium-iron-phosphate (mabatire a LFP). Ukadaulo wa batri wa sodium ndi ukadaulo wa batri la lithiamu ndiukadaulo wolonjeza, koma ali ndi mawonekedwe apadera omwe amawapangitsa kukhala oyenera kugwiritsa ntchito mosiyanasiyana. M'nkhaniyi, tiwona zomwe mabatire a sodium-ion ndi lithiamu-iron-phosphate ali, ndikufanizira kusiyana kwawo malinga ndi zomwe zapeza posachedwa.
Kodi Mabatire a Sodium-ion (SIBs) ndi chiyani?
Mabatire a sodium-ion (SIBs)ndi mtundu wa batire yowonjezeredwa yomwe imagwiritsa ntchito ayoni a sodium (Na+) ngati zonyamulira. Sodium ndi yochuluka komanso yotsika mtengo, zomwe zimapangitsa ma SIB kukhala teknoloji yatsopano ya batri m'malo mwa lithiamu.
Ma SIB nthawi zambiri amagwiritsa ntchito kaboni wolimba ngati zinthu za anode, zomwe ndizosiyana ndi ma graphite omwe amagwiritsidwa ntchito mu LIBs. Zida za cathode zimatha kusiyana, koma nthawi zambiri zimapangidwira kuti zigwirizane ndi kukula kwakukulu kwa ayoni a sodium poyerekeza ndi lithiamu ions.
Kodi Mabatire a LFP (Lithium-iron-phosphate Battery) ndi chiyani?
Mabatire a Lithium-iron-phosphate (mabatire a LFP)ndi subtype ya batire ya lithiamu-ion yomwe imagwiritsa ntchito lithiamu iron phosphate (LiFePO4) monga cathode zakuthupi.
Mabatire a Lithium LiFePO4 amadziwika chifukwa cha kukhazikika kwawo, moyo wautali, komanso chitetezo.
Amagwiritsidwa ntchito kwambiri pamagalimoto amagetsi (EVs), kusungirako mphamvu zongowonjezwdwa, ndi ntchito zina zomwe chitetezo ndi moyo wautali ndizofunikira.

| Zofananira Zofananira | Battery ya sodium-ion | Battery ya Lithium-iron-phosphate |
| Magwiridwe Amagetsi | - Imakhudzidwa kwambiri ndi kuchuluka kwa ndalama (SOC) ndi kutentha. - Kukana kwa pulse ndi impedance kumawonjezeka kwambiri pa SOC otsika (<30%) koma kuchepa pa SOC yapamwamba. | - Kudalira kochepa pa SOC ndi kutentha. - Kukana kokhazikika komanso kutsekeka pamitundu yosiyanasiyana ya SOC ndi kutentha. |
| Anode Material | Amagwiritsa ntchito kaboni wolimba ngati zinthu za anode, zoyenera kuphatikizika kwa sodium ion ndi deintercalation. | Amagwiritsa ntchito graphite ngati zinthu za anode, zoyenera kuti lifiyamu ion intercalation ndi deintercalation. |
| Kuchita Mwachangu ndi Kutayika Kwa Mphamvu | - Kuchita bwino kumadalira kwambiri SOC. - Kutayika kwa mphamvu kumachepetsedwa kwambiri poyendetsa pakati pa 50% -100% SOC. | - Kuchita bwino kumatengera SOC. - Imasunga bwino magwiridwe antchito osiyanasiyana a SOC. |
| Mtengo ndi Kuchuluka kwa Zinthu | - Sodium ndi yochuluka komanso yotsika mtengo, yopereka zabwino zomwe zingatheke. - Tekinoloje ndi njira zopangira zikukulabe, zomwe zingachepetse phindu lanthawi yochepa. | - Lithiamu ndiyosowa komanso yokwera mtengo. - Njira zopangira okhwima komanso njira zogulitsira zokhazikitsidwa zimapangitsa kuti zikhale zotsika mtengo pakanthawi kochepa. |
| Mapulogalamu | - Yoyenera kugwiritsa ntchito zotsika mtengo, monga kusungirako magetsi a gridi. - Zoyenera kugwiritsa ntchito pomwe kulemera ndi kukula sizofunikira kwambiri. | - Zoyenera kugwiritsa ntchito zomwe zimafunikira chitetezo chokwanira komanso kukhazikika, monga magalimoto amagetsi ndi kusungirako mphamvu zadzuwa. - Zoyenera pazithunzi zomwe zimafuna moyo wautali komanso kudalirika kwakukulu. |
| Kutentha Kwambiri | - Magwiridwe amasinthasintha kwambiri pansi pa kutentha kotsika kapena kokwera. - Kusintha kwa kutentha kumakhudza kwambiri kukana ndi kulepheretsa. | - Kukhazikika kokhazikika pamatenthedwe ambiri. - Kusintha kwa kutentha kumakhudza magwiridwe antchito. |
| Kuchuluka kwa Mphamvu | - Kutsika kwamphamvu kwamphamvu, koyenera kugwiritsidwa ntchito pomwe kachulukidwe kamphamvu si chinthu chofunikira kwambiri. | - Kuchuluka kwamphamvu kwamagetsi, koyenera kugwiritsa ntchito zomwe zimafunikira mphamvu zambiri, monga magalimoto amagetsi. |
| Chitetezo | - Chitetezo chabwino, koma anode yolimba ya carbon ikhoza kuyambitsa hysteresis. | - Chitetezo chabwino kwambiri, kukhazikika kwamafuta ambiri, komanso chiwopsezo chochepa cha kuthawa kwamafuta. |
| Kafukufuku ndi Chitukuko | - Ukadaulo ukadali pakukula, kafukufuku wokhudza kukhathamiritsa kwa anode ndi cathode kuti apititse patsogolo magwiridwe antchito. | - Ukadaulo wokhwima, wofufuza womwe umayang'ana kwambiri kupititsa patsogolo kachulukidwe wamagetsi ndikuchepetsa mtengo. |
Chidule:
- ⭐Mabatire a sodium-ion (SIBs) amapereka maubwino pamtengo ndi kuchuluka kwa zinthu, koma amakhudzidwa kwambiri ndi kutentha ndi SOC, kuwapangitsa kukhala oyenera kugwiritsa ntchito zotsika mtengo komanso zofunikira zocheperako.
- ⭐LiFePO4 Mabatire a Solar zimapambana pakukhazikika, chitetezo, ndi magwiridwe antchito, kuwapanga kukhala abwino kwa mapulogalamu omwe amafunikira magwiridwe antchito apamwamba, chitetezo, komanso moyo wautali.
Gome ili limapereka kufananitsa momveka bwino komanso mwachilengedwe kwa matekinoloje awiri a batri, kuthandiza ochita zisankho kusankha njira yoyenera kwambiri potengera zosowa zapadera.
Mapeto
Onse sodium-ion ndilithiamu ion phosphate mabatireali ndi ubwino ndi zovuta zawo zapadera. Mabatire a sodium amapereka mwayi wochepetsera mtengo chifukwa cha kuchuluka kwa sodium, koma amakhudzidwa kwambiri ndi kusintha kwa SOC ndi kutentha, zomwe zingakhudze mphamvu zawo. Mbali inayi,LiFePO4 mabatire a lithiamuperekani ntchito yokhazikika, moyo wautali wautali, ndi chitetezo chapamwamba, kuwapanga kukhala abwino kwa machitidwe osiyanasiyana, makamaka pamene kudalirika kuli kofunikira.
Pamene kafukufuku akupitilira, titha kuyembekezera kupita patsogolo kwamatekinoloje onse awiri, zomwe zitha kubweretsa ku mapulogalamu atsopano ndikuchita bwino. Pakadali pano, kusankha pakati pa Sodium-ion ndilithiamu phosphate mabatirezidzatengera zofunikira za pulogalamuyo, kuphatikiza mtengo, magwiridwe antchito, ndi chitetezo.
Pomvetsetsa kusiyana pakati pa mitundu iwiri ya mabatire, makampani amatha kupanga zisankho zodziwika bwino za ukadaulo womwe umakwaniritsa zosowa zawo, kaya akupanga mabatire a magalimoto amagetsi, kusungirako mphamvu zongowonjezwdwa, kapena ntchito zina.
