1.Nkhani zowonongeka pambuyo pobwezeretsanso lithiamu iron phosphate
Msika wobwezeretsanso mabatire amagetsi ndi wamkulu, ndipo malinga ndi mabungwe ofufuza oyenerera, kuchuluka kwa mabatire aku China omwe adapuma pantchito akuyembekezeka kufika 137.4MWh pofika 2025.
Kutenga lithiamu iron phosphate mabatiremwachitsanzo, pali njira ziwiri zobwezeretsanso ndikugwiritsa ntchito mabatire ofananirako omwe adapuma pantchito: imodzi ndikugwiritsa ntchito ma cascade, ndipo ina ndikuchotsa ndi kukonzanso.
Kugwiritsa ntchito ma cascade kumatanthawuza kugwiritsa ntchito mabatire a lithiamu iron phosphate mphamvu yotsalira pakati pa 30% mpaka 80% pambuyo pa disassembly ndi recombination, ndikuzigwiritsa ntchito kumadera opanda mphamvu zochepa monga kusungirako mphamvu.
Kugwetsa ndi kubwezeretsanso, monga momwe dzinalo likusonyezera, kumatanthauza kugwetsedwa kwa mabatire amphamvu a lithiamu chitsulo mankwala pamene mphamvu yotsalayo ndi yosakwana 30%, ndi kuchira kwa zipangizo zawo, monga lithiamu, phosphorous, ndi chitsulo mu electrode yabwino.
Kugwetsa ndi kubwezeretsanso mabatire a lithiamu-ion kungachepetse migodi ya zinthu zatsopano kuti ziteteze chilengedwe komanso kukhala ndi phindu lalikulu lazachuma, kuchepetsa kwambiri ndalama zamigodi, ndalama zopangira zinthu, ndalama zogwirira ntchito, komanso ndalama zopangira mzere.
Cholinga cha kugwetsa ndi kubwezeretsanso batire ya lithiamu-ion makamaka imakhala ndi masitepe otsatirawa: choyamba, sonkhanitsani ndi kugawa mabatire a lifiyamu, kenako ndikuchotsa mabatire, ndipo potsiriza kulekanitsa ndi kuyenga zitsulo.Pambuyo pa opareshoni, zitsulo zobwezeretsedwa ndi zida zitha kugwiritsidwa ntchito popanga mabatire atsopano kapena zinthu zina, kupulumutsa kwambiri ndalama.
Komabe, tsopano kuphatikiza gulu la makampani obwezeretsanso mabatire, monga kampani ya Ningde Times Holding Co., Ltd. Guangdong Bangpu Circular Technology Co., Ltd., onse akukumana ndi vuto lalikulu: kubwezeretsanso mabatire kutulutsa zinthu zapoizoni ndikutulutsa zowononga zowononga. .Msikawu umafunika mwachangu matekinoloje atsopano kuti apititse patsogolo kuipitsidwa ndi kawopsedwe kakubwezeretsanso mabatire.
2.LBNL idapeza zida zatsopano zothetsera vuto la kuipitsa pambuyo pakubwezeretsanso batri.
Posachedwapa, Lawrence Berkeley National Laboratory(LBNL) ku United States analengeza kuti apeza zinthu zatsopano kuti abwezeretse zinyalala mabatire lifiyamu-ion ndi madzi basi.
Lawrence Berkeley National Laboratory idakhazikitsidwa mu 1931 ndipo imayendetsedwa ndi University of California ku US Department of Energy's Science Office.Wapambana Mphotho 16 za Nobel.
Zatsopano zomwe zidapangidwa ndi Lawrence Berkeley National Laboratory zimatchedwa Quick-Release Binder.Mabatire a lithiamu-ion opangidwa kuchokera kuzinthuzi amatha kubwezeredwanso mosavuta, osawononga chilengedwe, komanso opanda poizoni.Amangofunika kuphwanyidwa ndikuyika m'madzi amchere, ndikugwedezeka pang'onopang'ono kuti alekanitse zinthu zofunika.Kenako zitsulozo zimasefedwa m’madzi n’kuziwumitsa.
Poyerekeza ndi kukonzanso kwa lithiamu-ion, komwe kumaphatikizapo kuphwanyidwa ndi kupera mabatire, kutsatiridwa ndi kuyaka kwa chitsulo ndi kulekanitsa zinthu, kumakhala ndi kawopsedwe koopsa komanso kusagwira bwino ntchito kwachilengedwe.Zatsopanozi zili ngati usiku ndi usana poziyerekeza.
Chakumapeto kwa Seputembala 2022, ukadaulo uwu udasankhidwa kukhala imodzi mwamaukadaulo osintha 100 opangidwa padziko lonse lapansi mu 2022 ndi R&D 100 Awards.
Monga tikudziwira, mabatire a lithiamu-ion amakhala ndi maelekitirodi abwino ndi oipa, olekanitsa, electrolyte, ndi zipangizo zamapangidwe, koma momwe zigawozi zimagwirizanirana ndi mabatire a lithiamu-ion sizidziwika bwino.
Mu mabatire a lithiamu-ion, chinthu chofunikira kwambiri chomwe chimasunga mawonekedwe a batri ndi zomatira.
Quick-Release Binder yatsopano yopezedwa ndi ofufuza a Lawrence Berkeley National Laboratory imapangidwa ndi polyacrylic acid (PAA) ndi polyethylene imine (PEI), zomwe zimalumikizidwa ndi ma atomu a nayitrogeni okhala ndi mpweya wabwino mu PEI ndi maatomu a okosijeni osayendetsedwa bwino ku PAA.
Pamene Quick-Release Binder imayikidwa m'madzi amchere okhala ndi sodium hydroxide (Na+OH-), ma ayoni a sodium amalowa mwadzidzidzi pamalo omatira, kulekanitsa ma polima awiriwo.The anapatukana ma polima kupasuka mu madzi, kumasula aliyense ophatikizidwa elekitirodi zigawo zikuluzikulu.
Pankhani ya mtengo, ikagwiritsidwa ntchito popanga ma electrode a lithiamu batire zabwino ndi zoipa, mtengo wa zomatirazi ndi pafupifupi gawo limodzi mwa magawo khumi mwa awiri omwe amagwiritsidwa ntchito kwambiri.
