1 Ibhethri ye-lithium
Ibhethri ye-lithium iwuhlobo lwebhethri elisebenzisa insimbi ye-lithium noma i-lithium alloy njengento engalungile ye-electrode futhi isebenzisa isixazululo se-electrolyte esinganamanzi.Amandla ayo athile aphezulu kakhulu, kodwa anezingozi ezingaba khona zokuphepha.I-electrode esebenzayo yebhethri ye-lithium i-manganese dioxide noma i-thionyl chloride, futhi into engalungile ye-electrode yi-lithium.Ngemva kokuba ibhethri selihlanganisiwe, ibhethri iba ne-voltage futhi ayidingi ukushajwa.Lolu hlobo lwebhethri nalo lungashajwa, kodwa ukusebenza komjikelezo akukuhle.Ngesikhathi somjikelezo wokushaja nokukhipha, kulula ukwenza i-lithium dendrites, okuholela ekujikelezeni okufushane kwangaphakathi kwebhethri, ngakho ngokuvamile lolu hlobo lwebhethri aluvunyelwe ukushajwa.
Ibhethri ye-Lithium Ion
Ibhethri ye-Lithium Ion (Ibhubesi) ibhekisela ebhethrini elishajekayo elisebenzisa ama-ion e-lithium njengezisetshenziswa ezisebenzayo.Uma ibhethri likhishwa ku-voltage yokunqanyulwa, lingashajwa kabusha ukuze kubuyiselwe isimo ngaphambi kokuphuma.Amabhethri e-lithium-ion agcina futhi akhulule ama-ion e-lithium ngezinto ezisebenzayo ezimbozwe kuma-electrode, okungukuthi, ukugcina amandla kagesi ngokuhlukaniswa kwe-lithium ion ezintweni ezisebenzayo ze-electrode.Ingqikithi yamabhethri e-lithium ion empeleni ukusebenzisa umehluko wokuhlushwa we-lithium ion ukugcina amandla nokukhipha.Ayikho i-lithium yensimbi ebhethri, ngakho ukuphepha kwayo kungcono kunamabhethri e-lithium, futhi amandla athile amabhethri e-lithium ion aphansi kunalawo amabhethri e-lithium.amandla.
3 Umehluko phakathi kwebhethri ye-lithium nebhethri ye-lithium ion
Ngokombono, amabhethri e-lithium namabhethri e-lithium-ion ayimiqondo ehlukene.Ibhethri esebenzisa insimbi ye-lithium njengento ye-electrode ibizwa ngokuthi ibhethri ye-lithium, okungelebhethri eliyinhloko.Ingalahlwa ngemva kokusetshenziswa futhi ayikwazi ukuphinda isetshenziswe.I-electrode esebenzayo yebhethri ye-lithium ion i-lithium cobalt oxide (noma enye i-lithium metal oxide), futhi into engalungile ye-electrode yi-carbon material.Ukuze uyihlukanise nebhethri ye-lithium yendabuko, ibizwa ngebhethri ye-lithium ion.Amabhethri e-lithium-ion amabhethri esibili angashajwa futhi asetshenziswe kabusha, okungukuthi, amabhethri ethu ajwayelekile aphinde ashajwe.Ezimpilweni zansuku zonke, abantu abaningi bayabadida bobabili futhi babize amabhethri e-lithium-ion afushanisiwe njengamabhethri e-lithium, okuholela ekudidekeni kwemiqondo.
Kukhona futhi umehluko omkhulu kakhulu phakathi kwamabhethri e-lithium namabhethri e-lithium ion electrochemically, okungukuthi, i-voltage yokukhipha.Ngokuvamile, isiteji sokukhipha ibhethri ye-lithium yi-3.0 V, ngakho-ke i-voltage yebhethri ye-lithium yamakhamera amaningi i-3.0 V, futhi ibhethri ye-lithium eyisipele yefoni ephathekayo nayo i-3.0 V. Isiteji sokukhipha isilinganiso se-lithium-ion amabhethri aphakathi kuka-3.6 no-3.8 V. Njengamanje, iningi lamabhethri e-lithium-ion omakhalekhukhwini ane-voltage yegama engu-3.7 V, kanti amanye asevele angu-3.8 V. Le volthi ebizwa ngokuthi ingasetshenziswa futhi ukuhlukanisa amabhethri e-lithium-ion ku-lithium. amabhethri.Empilweni, akuqinile ukubiza amabhethri asetshenziswa kumakhamera, amakhompyutha aphathekayo kanye nomakhalekhukhwini njengamabhethri e-lithium aphinde ashajwa noma amabhethri e-lithium.Ibizwa ngokuthi amabhethri e-lithium ion futhi ifushanisiwe njenge-Li-ion noma i-Li+.Isifinyezo sebhethri ye-lithium sithi Li, ngaphandle kokuthi + (uphawu lwe-ion oluhle).
