Poyerekeza ndi mabatire ena cylindrical ndi masikweya, ma CD osinthikamabatire a lithiamuakuchulukirachulukira kuchulukirachulukira pakugwiritsa ntchito chifukwa cha zabwino za kapangidwe kake kosinthika komanso kuchuluka kwamphamvu kwamphamvu.Kuyesa kwafupipafupi ndi njira yabwino yowunikira mabatire a lithiamu osinthika.Pepalali likuwunika mtundu wolephera wa mayeso afupipafupi a batri kuti apeze zinthu zazikulu zomwe zimakhudza kulephera kwafupipafupi;amasanthula chitsanzo cholephera pochita chitsimikiziro chachitsanzo pansi pazikhalidwe zosiyanasiyana ndikupereka malingaliro opititsa patsogolo chitetezo cha mabatire a lithiamu osinthika.
Kulephera kwafupipafupi kwa kusinthasinthakunyamula mabatire a lithiamunthawi zambiri zimaphatikizapo kutayikira kwamadzimadzi, kusweka kouma, moto ndi kuphulika.Kutayikira ndi kusweka kowuma nthawi zambiri kumachitika m'dera lofooka la phukusi la thumba, pomwe phukusi la aluminiyamu lowuma limatha kuwoneka bwino pambuyo pa mayeso;moto ndi kuphulika ndi zoopsa kwambiri ngozi kupanga chitetezo, ndipo chifukwa nthawi zambiri zachiwawa anachita electrolyte pansi zinthu zina pambuyo zotayidwa pulasitiki youma akulimbana.Chifukwa chake, poyerekeza ndi mayeso afupipafupi a batire ya lithiamu yosinthika, mkhalidwe wa phukusi la aluminium-pulasitiki ndiye chinthu chofunikira kwambiri chomwe chimayambitsa kulephera.
Mumayeso afupipafupi, voteji yotseguka yozungulirabatirenthawi yomweyo imatsika mpaka zero, pomwe mphamvu yayikulu ikudutsa muderali ndipo kutentha kwa Joule kumapangidwa.Kukula kwa kutentha kwa Joule kumadalira zinthu zitatu: panopa, kukana ndi nthawi.Ngakhale kuti mpweya wozungulira umakhalapo kwakanthawi kochepa, kutentha kwakukulu kumatha kupangidwabe chifukwa champhamvu kwambiri.Kutentha uku kumatulutsidwa pang'onopang'ono mu nthawi yochepa (kawirikawiri mphindi zochepa) pambuyo pa dera lalifupi, zomwe zimabweretsa kuwonjezeka kwa kutentha kwa batri.Pamene nthawi ikuwonjezeka, kutentha kwa Joule kumatayika makamaka ku chilengedwe ndipo kutentha kwa batri kumayamba kutsika.Chifukwa chake, zimaganiziridwa kuti kulephera kwa batire kwakanthawi kochepa kumachitika pakanthawi kochepa komanso kwakanthawi kochepa pambuyo pake.
Chodabwitsa cha kuphulika kwa mpweya nthawi zambiri chimapezeka muyeso lalifupi la ma CD a lithiamu batire, zomwe ziyenera kuyambitsidwa ndi zifukwa zotsatirazi.Choyamba ndi kusakhazikika kwa dongosolo la electrochemical, mwachitsanzo, kuwonongeka kwa oxidative kapena reductive kwa electrolyte komwe kumachitika chifukwa chapamwamba pakali pano kudutsa pakati pa electrode ndi electrolyte, ndipo mankhwala a gasi amadzazidwa mu phukusi la aluminium-pulasitiki.Kuphulika kwa gasi komwe kumachitika chifukwa cha ichi kumawonekera kwambiri pa kutentha kwakukulu, chifukwa mbali zowola za electrolyte zimatha kuchitika pa kutentha kwakukulu.Kuonjezera apo, ngakhale electrolyte si akukumana ndi kuwonongeka mbali zimachitikira, mwina pangʻono vaporized ndi Joule kutentha, makamaka zigawo electrolyte ndi otsika nthunzi kuthamanga.Kuphulika kwa mpweya chifukwa cha chifukwa ichi kumakhudzidwa kwambiri ndi kutentha, mwachitsanzo, chotupacho chimasowa pamene kutentha kwa selo kumatsika mpaka kutentha.Komabe, mosasamala kanthu za zomwe zimapangidwira mpweya, kuthamanga kwa mpweya wokwera mkati mwa batire panthawi yochepa kumakulitsa kung'ambika kouma kwa phukusi la aluminium-pulasitiki ndikuwonjezera mwayi wolephera.
Kutengera kusanthula kwa ndondomeko ndi limagwirira kulephera yochepa dera, chitetezo flexible ma CD lithiamu.mabatirezitha kusinthidwa kuchokera kuzinthu izi: kukhathamiritsa dongosolo la electrochemical, kuchepetsa kukana kwa khutu kwabwino komanso koyipa, ndikuwongolera mphamvu ya phukusi la aluminium-pulasitiki.Kukhathamiritsa kwa dongosolo la electrochemical kumatha kuchitika kuchokera kumakona osiyanasiyana, monga zinthu zabwino komanso zoyipa zogwira ntchito, chiŵerengero cha electrode ndi electrolyte, kuti apititse patsogolo mphamvu ya batri yopirira kutentha kwanthawi yayitali komanso kwakanthawi kochepa.Kuchepetsa kukana kwa lug kungathe kuchepetsa kutentha kwa Joule ndi kudzikundikira m'dera lino ndikuchepetsa kwambiri kutentha kwa malo ofooka a phukusi.Kupititsa patsogolo mphamvu ya phukusi la aluminiyamu-pulasitiki kungapezeke mwa kukhathamiritsa magawo mu ndondomeko yopangira batri, kuchepetsa kwambiri kuchitika kwa kuphulika kouma, moto ndi kuphulika.
