Lithium iron phosphate batire ndi ternary lithiamu batire, yomwe ili bwino?

Pamene tikupita ku tsogolo loyera, lobiriwira, kufunikira kwa njira zosungiramo mphamvu zogwirira ntchito, zokhazikika zikukula mofulumira. Chimodzi mwazinthu zomwe zikuyembekezeka ndi mabatire a lithiamu-ion, omwe ayamba kutchuka chifukwa cha kuchuluka kwa mphamvu zawo komanso moyo wawo wautali poyerekeza ndi mabatire amtundu wa lead-acid. M'kati mwabatri ya lithiamu-ionbanja, mitundu iwiri ikuluikulu yomwe nthawi zambiri imafanizidwa ndi mabatire a lithiamu iron phosphate (LiFePO4) ndi mabatire a lithiamu ternary. Kotero, tiyeni tifufuze mozama: ndi iti yomwe ili bwino?

Za mabatire a lithiamu iron phosphate

Mabatire a Lithium iron phosphate (LiFePO4) amadziwika chifukwa cha kukhazikika kwawo, chitetezo, komanso moyo wautali. Ndi batire yowonjezereka yomwe imagwiritsa ntchito ma ion a lithiamu kusunga ndi kumasula mphamvu panthawi yamalipiro ndi kutulutsa. Poyerekeza ndi mabatire a ternary lithiamu, mabatire a lithiamu iron phosphate amakhala ndi mphamvu zochepa, koma kukhazikika kwawo komanso moyo wawo wonse zimapanga kusowa kumeneku. Mabatirewa amakhala ndi kukhazikika kwamafuta ambiri, kuwapangitsa kukhala osagwirizana ndi kutentha kwambiri komanso kuchepetsa chiwopsezo cha kuthawa kwamafuta, zomwe zimadetsa nkhawa kwambiri pazogwiritsa ntchito zambiri. Kuonjezera apo, mabatire a LiFePO4 amatha kupirira maulendo apamwamba kwambiri ndi kutulutsa, mpaka maulendo a 2000 kapena kuposerapo, kuwapanga kukhala abwino kwa nthawi yayitali, ntchito zogwira ntchito kwambiri monga magalimoto amagetsi (EVs).

Za mabatire a ternary lithiamu

Kumbali ina, mabatire a ternary lithiamu, omwe amadziwikanso kuti lithiamu nickel-cobalt-aluminium oxide (NCA) kapena lithiamu nickel-manganese-cobalt oxide (NMC) mabatire, amapereka mphamvu zowonjezera mphamvu kuposa mabatire a LiFePO4. Kuchulukirachulukira kwamagetsi kumapangitsa kuti pakhale malo osungira ambiri komanso kuti chipangizocho chikhale nthawi yayitali. Kuphatikiza apo, mabatire a ternary lithiamu nthawi zambiri amapereka mphamvu zochulukirapo, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kuphulika kwamphamvu kwamphamvu, monga zida zamagetsi kapena zamagetsi zamagetsi. Komabe, pamene kuchuluka kwa mphamvu kumawonjezeka, pali zosintha zina. Mabatire a Ternary lithiamu akhoza kukhala ndi moyo waufupi wautumiki ndipo amatha kukhala ndi vuto la kutentha komanso kusakhazikika kuposa mabatire a LiFePO4.

Kuzindikira kuti ndi batire liti lomwe lili bwino kumatengera zofunikira za pulogalamuyo. Kumene chitetezo ndi moyo wautali ndizofunikira kwambiri, monga magalimoto amagetsi kapena mphamvu zowonjezera mphamvu, mabatire a lithiamu iron phosphate ndiye chisankho choyamba. Kukhazikika, moyo wautali wozungulira, komanso kukana kuthawa kwamafuta kwa mabatire a LiFePO4 kumawapangitsa kukhala chisankho chabwino kwambiri pazofunikira zomwe chitetezo ndichofunika kwambiri. Kuphatikiza apo, pamapulogalamu omwe amafunikira kutulutsa mphamvu kwamphamvu kosalekeza kapena komwe kulemera ndi malo ndizofunikira kwambiri, mabatire a ternary lithiamu akhoza kukhala chisankho choyenera chifukwa cha kuchuluka kwa mphamvu zawo.

Mitundu yonse iwiri ya mabatire ili ndi zabwino ndi zovuta zake, ndipo zofunikira zenizeni za pulogalamuyo ziyenera kuganiziridwa mosamala musanapange chisankho. Zinthu monga chitetezo, moyo wonse, kuchuluka kwa mphamvu, kutulutsa mphamvu, ndi mtengo wake ziyenera kuganiziridwa.

Mwachidule, palibe wopambana wodziwikiratu pamtsutso pakati pa mabatire a lithiamu iron phosphate ndi mabatire a ternary lithiamu. Njira iliyonse ili ndi ubwino ndi zovuta zake, ndipo kusankha kumadalira zosowa za ntchito yeniyeni. Pamene teknoloji ikupitirizabe kukula, mitundu yonse ya mabatire a Li-ion mosakayikira idzayenda bwino pakugwira ntchito, chitetezo ndi mphamvu zonse. Ziribe kanthu kuti mumasankha batire liti, ndikofunikira kupitiliza kukumbatira ndikuyika ndalama munjira zosungika zosungika bwino komanso zachilengedwe zomwe zimathandizira tsogolo lobiriwira kwa onse.

Ngati muli ndi chidwi mabatire lifiyamu, olandiridwa kulankhula lithiamu batire kampani kuwala kwaWerengani zambiri.
