Munyika iri kushanduka nekukurumidza yekuchengetedza simba, mhando mbiri dzemabhatiri dzave dzichinyanya kutaurwa:Mabhatiri eSodium-ion (SIBs)uyeMabhatiri eLithium-iron-phosphate (mabhatiri eLFP). Tekinoroji yebhatiri resodium netekinoroji yebhatiri relium matekinoroji ane tariro, asi ane hunhu hwakasiyana hunoita kuti akwanise kushandiswa zvakasiyana. Muchinyorwa chino, tichaongorora kuti mabhatiri esodium-ion nelithium-iron-phosphate chii, tobva taenzanisa mutsauko wawo zvichibva pane zvakawanikwa munguva pfupi yapfuura.
Chii chinonzi Mabhatiri eSodium-ion (SIBs)?
Mabhatiri eSodium-ion (SIBs)imhando yebhatiri rinochajwa rinoshandisa sodium ions (Na+) senzira yekutakura chaji. Sodium yakawanda uye isingadhuri, zvichiita kuti SIBs ive tekinoroji itsva yebhatiri yekutsiva lithium.
MaSIB anowanzo shandisa hard carbon seanode material, iyo yakasiyana negraphite inowanzoshandiswa muLIBs. Cathode materials anogona kusiyana, asi anowanzo gadzirwa kuti akwane saizi yakakura yesodium ions zvichienzaniswa ne lithium ions.
Chii chinonzi LFP Bateri (Lithium-iron-phosphate Battery)?
Mabhatiri eLithium-iron-phosphate (mabhatiri eLFP)mhando ye lithium-ion battery storage inoshandisa lithium iron phosphate (LiFePO4) se cathode material.
Mabhatiri eLithium LiFePO4 anozivikanwa nekugadzikana kwawo pakupisa, hupenyu hwekufamba kwenguva refu, uye kuchengetedzeka.
Dzinoshandiswa zvakanyanya mumotokari dzemagetsi (EV), mukuchengetedza simba rinogona kushandiswazve, uye mune zvimwe zvinoshandiswa uko kuchengetedzeka nekugara kwenguva refu zvakakosha.

| Maitiro Ekuenzanisa | Bhatiri reSodium-ion | Bhatiri reLithium-simbi-phosphate |
| Kushanda Kwemagetsi | - Inonyanya kubatwa nemamiriro ekuchaja (SOC) uye tembiricha. - Kuramba kwemwoyo uye kupindira kweropa kunowedzera zvakanyanya kana SOC yakaderera (<30%) asi kunoderera kana SOC yakakwira. | - Kusavimba zvakanyanya neSOC netembiricha. - Kuramba kwakasimba uye kupindirana pakati peSOC dzakasiyana uye tembiricha. |
| Zvinhu zveAnode | Inoshandisa hard carbon senzvimbo yeanode, yakakodzera kushandiswa kwe sodium ion intercalation uye deintercalation. | Inoshandisa graphite sechinhu chinoumba anode, yakakodzera lithium ion intercalation uye deintercalation. |
| Kushanda Nesimba Uye Kurasikirwa Nesimba | - Kushanda zvakanaka kunoenderana zvikuru neSOC. - Kurasikirwa kwesimba kunoderera zvakanyanya kana uchishandiswa nebhasikoro pakati pe50%-100% SOC. | - Kushanda zvakanaka hakubvi pane SOC. - Inochengetedza kushanda zvakanaka nguva dzose mumhando dzakasiyana dzeSOC. |
| Mutengo uye Kuwanda Kwezvinhu | - Sodium yakawanda uye inodhura zvishoma, zvichipa mikana yakanaka yemutengo. - Tekinoroji nemaitiro ekugadzira zvinhu zvichiri kufambira mberi, izvo zvinogona kuderedza mabhenefiti emari yenguva pfupi. | - Lithium haiwanikwe zvakanyanya uye inodhura zvakanyanya. - Maitiro ekugadzira zvinhu akura uye nzira dzekugadzira zvinhu dzakasimukira zvinoita kuti zvive nemutengo wakaderera munguva pfupi. |
| Mashandisirwo | - Yakakodzera kushandiswa kusingadhuri zvakanyanya, senge kuchengetedza simba regrid. - Yakanakira kushandiswa uko huremu nehukuru zvisinganyanyi kukosha. | - Yakakodzera kushandiswa kunoda kuchengetedzeka kwakanyanya uye kugadzikana, senge mota dzemagetsi uye nzvimbo yekuchengetedza simba rezuva. - Yakanakira mamiriro ezvinhu anoda hupenyu hwenguva refu uye kuvimbika kwakanyanya. |
| Kunzwisisa Tembiricha | - Mashandiro anochinja-chinja zvakanyanya kana tembiricha yakaderera kana yakakwira. - Kuchinja kwekushisa kunokanganisa zvakanyanya kuramba uye kupindira kwemhepo. | - Kushanda kwakagadzikana pamhando dzakasiyana dzekupisa. - Kuchinja kwetembiricha hakuna zvakunokanganisa pakushanda kwechinhu. |
| Kuwanda kweSimba | - Kuwanda kwesimba kushoma, kwakakodzera kushandiswa uko kuwanda kwesimba kusiri chinhu chakakosha. | - Simba rakawanda, rakakodzera kushandiswa kunoda simba rakawanda, senge mota dzemagetsi. |
| Kuchengetedzeka | - Kuchengetedzwa kwakanaka, asi anode yekabhoni yakaoma inogona kukonzera hysteresis. | - Kuchengetedzeka kwakanaka, kugadzikana kwakanyanya kwekupisa, uye njodzi shoma yekupisa kutiza. |
| Tsvagiridzo neKubudirira | - Tekinoroji ichiri kugadzirwa, nekutsvaga kwakatarisana nekugadzirisa zvinhu zveanode ne cathode kuti zvivandudze mashandiro. | - Tekinoroji yevakuru, ine tsvakurudzo yakatarisana nekuvandudza huwandu hwesimba uye kuderedza mitengo. |
Pfupiso:
- ⭐Mabhatiri eSodium-ion (SIBs) inopa zvakanakira mumutengo uye kuwanda kwezvinhu, asi inonyanya kukanganiswa nekupisa uye SOC, zvichiita kuti dzikwanise kushandiswa zvinoderedza mitengo uye zvisinganyanyi kuomarara pakushanda.
- ⭐Mabhatiri ezuva eLiFePO4 Inoshanda zvakanaka pakugadzikana, kuchengetedzeka, uye kushanda zvakanaka, zvichiita kuti ive yakakodzera kushandiswa kunoda kushanda kwepamusoro, kuchengetedzeka, uye kurarama kwenguva refu.
Tafura iyi inopa kuenzanisa kwakajeka uye kwakajeka kwematekinoroji maviri ebhatiri, zvichibatsira vagadziri vesarudzo kusarudza sarudzo yakakodzera zvichienderana nezvinodiwa chaizvo.
Mhedziso
Zvese Sodium-ion uyemabhatiri e lithium ion phosphateane zvakanakira nematambudziko awo akasiyana. Mabhatiri eSodium anogona kuderedza mitengo nekuda kwekuwanda kwesodium, asi anonyanya kunzwa shanduko muSOC netembiricha, izvo zvinogona kukanganisa mashandiro awo. Kune rumwe rutivi,Mabhatiri eLiFePO4 lithiuminopa kushanda kwakasimba, hupenyu hwenguva refu, uye kuchengetedzeka kwakanyanya, zvichiita kuti zvive zvakanaka kune akasiyana mashandisirwo, kunyanya uko kuvimbika kwakakosha.
Sezvo tsvakurudzo ichienderera mberi, tinogona kutarisira kufambira mberi mune matekinoroji ese ari maviri, zvingangotungamira kumashandisirwo matsva uye kushanda kuri nani. Parizvino, sarudzo pakati peSodium-ion nemabhatiri e lithium phosphatezvinoenderana nezvinodiwa zvechikumbiro, kusanganisira mutengo, mashandiro, uye kuchengetedzeka.
Nekunzwisisa mutsauko uripo pakati pemhando mbiri idzi dzemabhatiri, makambani anogona kuita sarudzo dzine ruzivo rwakadzama nezvekuti ndeipi tekinoroji inonyatsokodzera zvavanoda, kungave vari kugadzira mabhatiri emotokari dzemagetsi, kuchengetedza simba rinogona kushandiswazve, kana zvimwe zvinoshandiswa.
