baterie ionic\u0103 cu litiu<\/h1>\n

Bateria ionic\u0103 cu litiu a devenit o component\u0103 indispensabil\u0103 \u00eentr-o mare varietate de dispozitive \u0219i vehicule, de la laptopuri \u0219i telefoane mobile la ma\u0219ini hibride \u0219i electrice. Avantajele lor variaz\u0103 de la densitatea energetic\u0103 ridicat\u0103, re\u00eenc\u0103rcabilitate \u0219i greutate redus\u0103 (cu p\u00e2n\u0103 la 70% mai u\u0219oare dec\u00e2t bateriile cu plumb-acid); siguran\u021b\u0103 sporit\u0103 f\u0103r\u0103 a produce subproduse toxice precum bateriile cu plumb-acid; \u00een plus, ele nu produc subproduse toxice precum bateriile cu plumb-acid; astfel, produc\u0103torii lor lucreaz\u0103 neobosit pentru a dezvolta materiale catodice\/anodice mai bune, electroli\u021bi solizi care asigur\u0103 baterii de mare capacitate pentru utilizarea \u00een siguran\u021b\u0103 \u00een cadrul bateriilor - doar pentru a men\u021bine aceste avantaje!<\/p>\n

Inova\u021biile recente includ o baterie ionic\u0103 cu litiu care utilizeaz\u0103 poli(lichid ionic) ca electrolit \u00een loc s\u0103 utilizeze solven\u021bi organici volatili precum cobaltul din LIB-urile actuale ca material electrolitic. Aceast\u0103 evolu\u021bie revolu\u021bionar\u0103 promite densit\u0103\u021bi energetice mai mari la costuri mai mici, cu o dependen\u021b\u0103 redus\u0103 de metale costisitoare \u0219i problematice, cum ar fi cobaltul care se g\u0103se\u0219te \u00een LIB-urile actuale.<\/p>\n

bateriile ionice cu litiu constau dintr-un anod, un catod, un separator \u0219i un electrolit; anodul stocheaz\u0103 ionii de litiu, \u00een timp ce catodul ac\u021bioneaz\u0103 ca un spa\u021biu de stocare a electronilor; \u00een timp ce un separator blocheaz\u0103 fluxul de electroni \u00een interiorul bateriei. \u00cen cele din urm\u0103, un electrolit transport\u0103 ioni de litiu \u00eenc\u0103rca\u021bi pozitiv \u00eentre anod \u0219i catod \u00een timpul desc\u0103rc\u0103rii \u0219i \u00eenapoi la anod \u00een timpul \u00eenc\u0103rc\u0103rii prin procese de intercalare\/deintercalare care au loc simultan - acest proces este cunoscut sub denumirea de intercalare\/deintercalare \u00een termeni tehnici.<\/p>\n

Un anod compus de obicei din material grafit este combinat cu un catod realizat din sulfuri sau nitruri metalice neinflamabile pentru a stoca ioni de litiu prin intercalare, unde ace\u0219tia sunt \u00eencorpora\u021bi fizic \u00eentre straturile 2D de carbon care alc\u0103tuiesc grafitul \u00een vrac, \u00een scopuri de stocare. Desc\u0103rcarea celulelor implic\u0103 un anod care sufer\u0103 o semireac\u021bie de oxidare care elibereaz\u0103 ioni de litiu pozitivi, cre\u00e2nd \u00een acela\u0219i timp electroni \u00eenc\u0103rca\u021bi negativ prin circuitele externe; \u00een timpul desc\u0103rc\u0103rii, anodul sufer\u0103 o semireac\u021bie de oxidare care produce ioni de litiu pozitivi, \u00een timp ce electronii \u00eenc\u0103rca\u021bi negativ sunt transporta\u021bi prin circuitul extern la catod, unde are loc o semireac\u021bie de reducere \u0219i curentul electric trece prin circuitul extern.<\/p>\n

Exist\u0103 mai multe tipuri, cum ar fi bateria litiu-ion de 72v, bateria litiu de 12 vol\u021bi 20ah, bateria litiu de 20ah. Reac\u021biile de oxidare-reducere trebuie s\u0103 aib\u0103 loc la temperatura \u0219i \u00een condi\u021biile optime; \u00een caz contrar, modific\u0103rile structurale semnificative ar putea reduce semnificativ capacitatea bateriei \u0219i ar putea sc\u0103dea ciclabilitatea acesteia (m\u0103sura num\u0103rului de \u00eenc\u0103rc\u0103ri \u0219i desc\u0103rc\u0103ri pe care o baterie le poate suporta \u00eenainte ca capacitatea sa s\u0103 \u00eenceap\u0103 s\u0103 scad\u0103), cresc\u00e2nd poten\u021bial presiunea intern\u0103 a celulei, ceea ce reprezint\u0103 o amenin\u021bare la adresa siguran\u021bei dispozitivelor mobile precum tabletele \u0219i smartphone-urile.<\/p>\n
