Ezweni elithuthukayo lokugcinwa kwamandla, izinhlobo ezimbili zamabhethri bezilokhu zisematheni:Amabhethri e-sodium-ion (SIBs)futhiAmabhethri e-Lithium-iron-phosphate (amabhethri e-LFP). Kokubili ubuchwepheshe bebhethri ye-sodium kanye nobuchwepheshe bebhethri ye-lithium ubuchwepheshe obuthembisayo, kodwa bunezici ezihlukile ezibenza bafanelekele izinhlelo zokusebenza ezahlukene. Kulesi sihloko, sizohlola ukuthi ayini amabhethri e-sodium-ion kanye ne-lithium-iron-phosphate, bese siqhathanisa umehluko wabo ngokusekelwe ekutholweni kwakamuva kocwaningo.
Ayini Amabhethri e-Sodium-ion (SIBs)?
Amabhethri e-sodium-ion (SIBs)ziwuhlobo lwebhethri elishajekayo elisebenzisa i-sodium ions (Na+) njengezithwali zokushaja. I-sodium iyiningi futhi ayibizi, okwenza ama-SIB abe ubuchwepheshe obusha bebhethri obuzothatha indawo ye-lithium.
Ama-SIB ngokuvamile asebenzisa ikhabhoni eqinile njenge-anode material, ehlukile ku-graphite evame ukusetshenziswa kuma-LIB. Izinto ze-cathode zingahluka, kodwa ngokuvamile zenzelwe ukuhlalisa ubukhulu obukhulu be-sodium ion uma kuqhathaniswa ne-lithium ion.
Ayini Amabhethri e-LFP (Ibhethri ye-Lithium-iron-phosphate)?
Amabhethri e-Lithium-iron-phosphate (amabhethri e-LFP)ziyi-subtype yesitoreji sebhethri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) njenge-cathode material.
Amabhethri e-Lithium LiFePO4 aziwa ngokuzinza kwawo okushisayo, impilo yomjikelezo omude, nokuphepha.
Asetshenziswa kakhulu ezimotweni zikagesi (EVs), ukugcinwa kwamandla avuselelekayo, nezinye izinhlelo zokusebenza lapho ukuphepha nokuphila isikhathi eside kubalulekile.

| Ukusebenza Kagesi | - Kuzwela kakhulu kusimo sezindleko (SOC) kanye nezinga lokushisa. - Ukumelana ne-Pulse kanye ne-impedance kukhuphuka kakhulu ku-SOC ephansi (<30%) kodwa yehla ku-SOC ephezulu. | - Ukuncika okuncane ku-SOC nezinga lokushisa. - Ukumelana okuzinzile kanye ne-impedance kuwo wonke ama-SOC ahlukahlukene kanye nezinga lokushisa. |
| I-Anode Material | Isebenzisa ikhabhoni eqinile njengezinto ze-anode, ifanele i-sodium ion intercalation kanye ne-deintercalation. | Isebenzisa i-graphite njengento ye-anode, ifanele i-lithium ion intercalation kanye ne-deintercalation. |
| Ukusebenza kahle kanye Nokulahlekelwa Amandla | - Ukusebenza kahle kuncike kakhulu ku-SOC. - Ukulahlekelwa kwamandla kwehle kakhulu lapho kugijinyiswa phakathi kuka-50% -100% SOC. | - Ukusebenza kahle kuncike kancane ku-SOC. - Igcina ukusebenza kahle okungaguquki kulo lonke uhla olubanzi lwe-SOC. |
| Izindleko Nokuchichima Kwempahla | - I-sodium inala futhi inezindleko eziphansi, inikeza izinzuzo ezingaba khona zezindleko. - Ubuchwepheshe nezinqubo zokukhiqiza zisathuthuka, ezingase zinciphise izinzuzo zezindleko zesikhashana. | - I-lithium ayitholakali kalula futhi ibiza kakhulu. - Izinqubo zokukhiqiza ezivuthiwe kanye nochungechunge lokuhlinzekwa kwempahla olusunguliwe lukwenza kungabizi kakhulu esikhathini esifushane. |
| Izinhlelo zokusebenza | - Ifanele izinhlelo zokusebenza ezingabizi kakhulu, njengokugcina amandla egridi. - Ilungele izinhlelo zokusebenza lapho isisindo nosayizi kungabalulekile kangako. | - Ifanele izicelo ezidinga ukuphepha okuphezulu nokuzinza, njengezimoto zikagesi kanye nesitoreji samandla elanga. - Ilungele izimo ezidinga impilo yomjikelezo omude nokuthembeka okuphezulu. |
| Ukuzwela kwezinga lokushisa | - Ukusebenza kushintshashintsha kakhulu ngaphansi kwamazinga okushisa aphansi noma aphezulu. - Ukushintsha kwezinga lokushisa kuthinta kakhulu ukumelana ne-impedance. | - Ukusebenza okuzinzile kulo lonke izinga lokushisa elibanzi. - Ukushintsha kwezinga lokushisa kunomthelela omncane ekusebenzeni. |

Isifinyezo:
- ⭐Amabhethri e-sodium-ion (SIBs) zinikeza izinzuzo ngezindleko nobuningi bezinto ezibonakalayo, kodwa zizwela kakhulu izinga lokushisa kanye ne-SOC, okuzenza zifanelekele izinhlelo zokusebenza ezingazweli izindleko ezinezidingo zokusebenza eziqinile kancane.
- ⭐I-LiFePO4 Amabhethri elanga zihamba phambili ngokuzinza, ukuphepha, nokusebenza kahle, okuzenza zilungele izinhlelo zokusebenza ezidinga ukusebenza okuphezulu, ukuphepha, nokuphila isikhathi eside.
Leli thebula linikeza ukuqhathanisa okucacile nokunembile kobuchwepheshe obubili bebhethri, lisiza abenzi bezinqumo ukuthi bakhethe inketho efaneleke kakhulu ngokusekelwe ezidingweni ezithile.
Isiphetho
Kokubili i-sodium ion kanyeamabhethri e-lithium ion phosphatebanezinzuzo nezinselele zabo eziyingqayizivele. Amabhethri e-sodium anikeza amandla ezindleko eziphansi ngenxa yobuningi be-sodium, kodwa azwela kakhulu ekushintsheni kwe-SOC namazinga okushisa, okungathinta ukusebenza kahle kwawo. Ngokolunye uhlangothi,I-LiFePO4 amabhethri e-lithiumhlinzeka ngokusebenza okuzinzile, impilo yomjikelezo omude, nokuphepha okuphezulu, okuyenza ilungele uhla olubanzi lwezinhlelo zokusebenza, ikakhulukazi lapho ukwethembeka kubalulekile.
Njengoba ucwaningo luqhubeka, singalindela ukuthuthuka okwengeziwe kukho kokubili ubuchwepheshe, okungase kuholele ezinhlelweni ezintsha zokusebenza nokusebenza okuthuthukisiwe. Okwamanje, ukukhetha phakathi kwe-Sodium-ion neamabhethri e-lithium phosphatekuzoncika kuzimfuneko ezithile zesicelo, okuhlanganisa izindleko, ukusebenza, nokucatshangelwa kokuphepha.
Ngokuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamabhethri, izinkampani zingenza izinqumo ezinolwazi olunzulu mayelana nokuthi ibuphi ubuchwepheshe obuzifanela kangcono izidingo zabo, noma ngabe bakhiqiza amabhethri ezimoto zikagesi, ukugcinwa kwamandla avuselelekayo, noma ezinye izinhlelo zokusebenza.
