1. Uxinaniso lwamandla aphezulu ebhetri ye-lithium iron phosphate

Ngokweengxelo, ubuninzi bamandla e-square aluminium iqokobhe i-lithium iron phosphate ibhetri eveliswe ngo-2018 imalunga ne-160Wh/kg, kwaye ezinye iinkampani zebhetri zinokufikelela kwinqanaba elimalunga ne-175-180Wh/kg ngo-2019, kunye neenkampani ezinamandla. inokugqithelana Inkqubo yokupakisha kunye nomthamo unokwenziwa mkhulu okanye i-185Wh/kg.

2. Ukhuseleko lwebhetri ye-lithium iron phosphate lulungile

Ukusebenza kwe-electrochemical yezinto ezimbi ze-electrode ye-lithium iron phosphate ibhetri izinzile. Oku kugqiba ukuba ineqonga lokutshaja kunye nokukhupha elingenamthungo, ngoko ke isakhiwo sebhetri sihlala singatshintshi ngexesha lokutshaja kunye nokukhupha inkqubo, ayiyi kuqhuma, kwaye ikhuselekile kakhulu phantsi kweemeko ezikhethekileyo ezifana nesekethe emfutshane, i-overcharge, extrusion, kunye ne-dipping. .

3. Ubomi obude bebhetri ye-lithium iron phosphate

Ubomi bomjikelezo we-1C weebhetri ze-lithium iron phosphate ngokubanzi zifikelela kumaxesha angama-2000, okanye nangaphezulu kwamaxesha angama-3500. Ukuthatha imarike yokugcina amandla njengomzekelo, iqinisekisa amaxesha angaphezu kwama-4000 ukuya kuma-5000, iminyaka eyi-8 ukuya kwe-10 yobomi, kunye neebhetri ze-ternary. Ubomi bomjikelezo wamaxesha angaphezu kwe-1000, ixesha elide likhokelela Ubomi bomjikelezo webhetri ye-asidi ngamaxesha angama-300. Icala lasekhohlo le-lithium iron phosphate ibhetri yi-anode eyenziwe yi-olivine-structured LiFePO4 material, edityaniswe ne-anode yebhetri kunye ne-aluminium foil. Ngasekunene yi-electrode engalunganga yebhetri eyenziwe ngekhabhoni (graphite), edityaniswe ne-electrode engalunganga yebhetri ngefoyile yobhedu. Embindini kukho i-membrane eyahlula i-polymer kwi-anode kunye ne-cathode. I-Lithium inokudlula kwi-membrane, ii-electron azikwazi. Ingaphakathi lebhetri lizaliswe nge-electrolyte, kwaye ibhetri ivalwe ngentsimbi yentsimbi.

Iibhetri ze-lithium ze-phosphate ze-iron zineengenelo ezininzi ezinje ngombane osebenza kakhulu, ukuxinana kwamandla aphezulu, ubomi bomjikelo omde, isantya esisezantsi sokuzikhupha, akukho nkumbulo, ukhuseleko lokusingqongileyo, njl. Inamathuba amahle okusebenza kuqhagamshelo lwegridi ekhuselekileyo yezikhululo zamandla ahlaziyekayo, ulawulo oluphezulu lwegridi, izikhululo zamandla ezisasazwayo, unikezelo lombane lwe-UPS, kunye neenkqubo zamandla ezingxamisekileyo.

Ngokunyuka kwemarike yokugcina amandla, ezinye iinkampani zebhetri zamandla ziye zasebenzisa iinkonzo zokugcina amandla kwiminyaka yamuva nje, zivula iimarike zesicelo esitsha kwiibhetri ze-lithium iron phosphate. Ngakolunye uhlangothi, i-lithium phosphate ineempawu zobomi obude, ukhuseleko, umthamo omkhulu, kunye nokukhuselwa kwendalo. Ukutshintshela kwintsimi yokugcina amandla kunokwandisa ikhonkco lexabiso kunye nokukhuthaza ukusekwa kweemodeli ezintsha zoshishino. Kwelinye icala, inkqubo yokugcina amandla edityaniswe nebhetri ye-lithium iron phosphate ibe lolona khetho luphambili kwimarike. Ngokweengxelo, iibhetri ze-lithium iron phosphate zisetyenziselwe ukumodareyithwa rhoqo kweebhasi zombane, iilori zombane, iitheminali zabasebenzisi, kunye neeterminals zegridi.

Ukuveliswa kwamandla ahlaziyekayo afana nokuveliswa kwamandla omoya kunye nokuveliswa kwamandla e-photovoltaic kuqhagamshelwe ngokukhuselekileyo kwigridi. Ukungakhethi kwendalo, ukungenelela kunye nokuguquguquka kokuveliswa kwamandla omoya kumisela ukuba uphuhliso olukhulu luya kuba nempembelelo ebalulekileyo ekusebenzeni okukhuselekileyo kwenkqubo yamandla. Ngophuhliso olukhawulezayo lweshishini lamandla omoya, ngakumbi uninzi lweefama zomoya kwilizwe lethu “zezophuhliso olukhulu olukwindawo esembindini kunye nothutho lomgama omde”, uphuhliso oluqhagamshelwe kwigridi yeefama zomoya ezinkulu zenza imingeni enzima ukusebenza kunye nokulawulwa kweegridi zamandla amakhulu.
