Ubwino wa Lithium Iron Phosphate (LiFePO4)

Lifepo4 imapereka magwiridwe antchito abwino a electrochemical ndi kukana kochepa.Izi zimatheka ndi nano-scale phosphate cathode material.Ubwino wofunikira ndi kuchuluka kwaposachedwa komanso moyo wautali wozungulira, kuphatikiza kukhazikika kwamafuta, chitetezo chokwanira komanso kulolerana ngati agwiritsidwa ntchito molakwika.

Li-phosphate ndi wololera ku zinthu zonse zolipiritsa ndipo sapanikizika kwambiri kuposa machitidwe ena a lithiamu-ion ngati asungidwa pamagetsi apamwamba kwa nthawi yayitali.Monga malonda, mphamvu yake yotsika ya 3.2V / selo imachepetsa mphamvu yeniyeni pansi pa cobalt-blended lithiamu-ion.Ndi mabatire ambiri, kutentha kozizira kumachepetsa magwiridwe antchito komanso kutentha kosungirako kumafupikitsa moyo wautumiki, ndipo Li-phosphate ndi chimodzimodzi.Li-phosphate imakhala ndi kudziyikira kwambiri kuposa mabatire ena a Li-ion, omwe angayambitse kusamvana ndi ukalamba.Izi zitha kuchepetsedwa pogula ma cell apamwamba kwambiri komanso / kapena kugwiritsa ntchito zida zamagetsi zowongolera, zonse zomwe zimawonjezera mtengo wa paketi.

Li-phosphate nthawi zambiri amagwiritsidwa ntchito m'malo mwa batire yoyambira asidi.Ndi ma cell anayi a Li-phosphate motsatizana, selo lililonse limakhala pamwamba pa 3.60V, yomwe ndi voteji yoyenera.Pakadali pano, mtengowo uyenera kuthetsedwa koma mtengo wokwera umapitilirabe poyendetsa.Li-phosphate imalekerera kuchulukitsidwa kwina;komabe, kusunga magetsi pa 14.40V kwa nthawi yaitali, monga momwe magalimoto ambiri amachitira paulendo wautali, akhoza kutsindika Li-phosphate.Kuzizira kozizira koyambira kumatha kukhala vuto ndi Li-phosphate ngati batire yoyambira.
