Iibhetri zeLithium-ionukuguqula amandla ekhemikhali abe ngamandla ombane ngokusabela kweekhemikhali eziqhelekileyo.Ngokwethiyori, ukusabela okwenzeka ngaphakathi kwebhetri kukusabela kokunciphisa i-oxidation phakathi kwee-electrode ezilungileyo kunye nezingalunganga.Ngokwale mpendulo, i-deintercalation ye-ion inokuvelisa okwangoku, ngoko ke lithium I-ion concentration idla ngokungatshintshi.Nangona kunjalo, kumjikelezo webhetri wangempela, ngaphezu kwempendulo eqhelekileyo ye-lithium ion, ezininzi iimpendulo zecala ziya kwenzeka, ezifana nokubunjwa kunye nokukhula kwefilimu ye-SEI, kunye nokuchithwa kwe-electrolyte.Nayiphi na impendulo enokuvelisa okanye idle i-lithium ion iya kuphazamisa ibhalansi yangaphakathi yebhetri.Emva kokuba ibhalansi itshintshile, iya kuba nefuthe elibi kwibhetri.Izinto zangaphakathi zebhetri ezibangela ukuhla kwamandla kunye nobomi bebhetri ye-lithium-ion zilandelayo: 1. Ukutshintshwa kwezinto ezilungileyo ze-electrode.2. I-electrolyte ibolile.3. Ukwenziwa kunye nokukhula kwefilimu ye-SEI.4. Ukwenziwa kwe-lithium dendrites.5. Impembelelo yezithako ezingasebenzi.
Indlela yokusilela yangaphakathi yeiibhetri ze-lithiumininzi ibangelwa ukubunjwa kwe-lithium dendrites, utshintsho kwi-cathode material kunye nokubola kwe-electrolyte.Phakathi kwazo, ukwakheka kwe-lithium dendrites kunokubangela ngokulula imijikelezo emfutshane kwaye kubangele ukubaleka kwe-thermal.iseli yebhetri.Yenza ukuba ibhetri iqhume.
Kuhlalutyo lokugqibela, uphando olungaphumeleliyo lweebhetri ze-lithium kukufunda iindlela zokungaphumeleli kwebhetri kunye neendlela, ukwandisa ibhetri, kunye nokuphucula ukhuseleko lwebhetri.Ke ngoko, uphando lokusilela kwebhetri alunakuba nokubaluleka okukhokelayo kuphela kwimveliso kunye nokusebenza, kodwa lunokubaluleka okubalulekileyo ekuphuculeni ubomi bebhetri, ukhuseleko kunye nokuthembeka kwezithuthi zombane, kunye nokunciphisa iindleko zezithuthi zombane.
