Kuyang'ana Makhalidwe Abwino a Copper Foam mu Mapulogalamu a Battery

Choyamba tiyenera kuyankha funso: Kodithovu lamkuwaconductive? Yankho ndi lakuti inde. Chithovu chamkuwa chimakhala ndi matenthedwe apamwamba komanso magetsi. Izi zimapangitsa kukhala chisankho chabwino kwambiri pamabatire, chifukwa kuyendetsa bwino kwamagetsi ndikofunikira kuti agwire bwino ntchito. Mapangidwe a porous a thovu lamkuwa amatha kupititsa patsogolo mphamvu ya electrolyte, potero kumapangitsa kuti batire igwire bwino ntchito. Kuphatikiza apo, malo ake okwera amapereka malo olumikizirana ndi ma elekitironi, kupititsa patsogolo mawonekedwe ake.

Kugwiritsa ntchito copper foam mubatirentchito si lingaliro chabe lachidziwitso koma layesedwa m'machitidwe othandiza. Kafukufuku ndi chitukuko m'munda wa ukadaulo wa batri wawonetsa zotsatira zabwino pogwiritsa ntchito thovu lamkuwa monga chotolera chamakono cha mabatire a lithiamu-ion. Ma conductivity ake apamwamba komanso porosity amawonetsa magwiridwe antchito a batri, kuphatikiza kuchuluka kwa mphamvu zamagetsi komanso kuthamanga kwachangu. Kupita patsogolo kumeneku kukuwonetsa kuthekera kwa thovu lamkuwa kuti ligwire ntchito yofunika kwambiri pakupanga ukadaulo wa batri.

Kuphatikiza apo, chithovu chamkuwa ndi chopepuka komanso chotsika mtengo, chomwe chimapangitsa kukhala njira yabwino yopangira batire yayikulu. Monga kufunikira kwa mabatire apamwamba kwambiri kukupitilira kukula m'mafakitale monga magalimoto amagetsi ndi kusungirako mphamvu zongowonjezwdwa, kufunikira kokwanira komanso kotsika mtengo.zida za batriikukhala yofunika kwambiri. Kuphatikizika kwa thovu la Copper, porosity, ndi kukwera mtengo kwake kumapangitsa kukhala munthu wodalirika kukwaniritsa zosowazi.

Ponseponse, conductive katundu wathovu lamkuwaipangitseni kukhala chisankho chokongola pamapulogalamu a batri. Kuwongolera kwake kwamagetsi ndi kutentha, kuphatikiza ndi kapangidwe kake ka porous, kumapereka zabwino zambiri pakuwongolera magwiridwe antchito ndi magwiridwe antchito a batri. Kafukufuku wopitilira ndi chitukuko m'derali akutsegula njira yogwiritsira ntchito thovu lamkuwa m'mabatire am'badwo wotsatira. Pomwe ukadaulo ukupitilira kupita patsogolo, ndizosangalatsa kuwona kuthekera kwa thovu lamkuwa kuti apange tsogolo losungira mphamvu ndikuthandizira dziko lokhazikika komanso lobiriwira.
