Ngexesha eliphawulwe yimfuno ekhulayo yemithombo yamandla avuselelekayo, iibhetri ze-lithium-ion ziye zavela njengomdlali ophambili kwiteknoloji yokugcina amandla.Ezi bhetri zinika uxinano lwamandla aphezulu, ubomi obude, kunye namaxesha okuhlaziya akhawulezayo, azenza zilungele ukunika amandla izithuthi zombane, izixhobo zombane eziphathwayo, kunye neenkqubo ezinkulu zokugcina amandla.Nangona kunjalo, oku kukhula ngokukhawuleza kokusetyenziswa kweiibhetri ze-lithium-ionikwaphakamisa iinkxalabo malunga nokhuseleko, ngakumbi ngokumalunga nokhuseleko lomlilo.
Iibhetri zeLithium-ionzaziwa ngokubeka umngcipheko womlilo, nangona usezantsi ngokwentelekiso.Ngaphandle koku, iziganeko ezimbalwa eziphezulu ezibandakanya umlilo webhetri ziye zaphakamisa iintsimbi ze-alam.Ukuqinisekisa ukwamkelwa okukhuselekileyo kunye nokusasazeka kweebhetri ze-lithium-ion, ukuqhubela phambili kwiteknoloji yokukhusela umlilo kubaluleke kakhulu.
Esinye sezizathu eziphambili zokutsha kwebhetri ye-lithium-ion yinto yokubaleka kwe-thermal.Oku kwenzeka xa ubushushu bangaphakathi bebhetri bunyukela kwindawo ebalulekileyo, okukhokelela ekukhululweni kweegesi ezinokutsha kunye nokubanakho ukulayita ibhetri.Ukulwa nokubaleka kwe-thermal, abaphandi basebenzisa iindlela ezahlukeneyo zokuphucula ukhuseleko lomlilo.
Esinye isisombululo silele ekuphuhliseni izinto ezintsha ze-electrode ezingafaneli kakhulu ekubalekeni kwe-thermal.Ngokutshintsha okanye ukuguqula izinto ezisetyenziswe kwi-cathode yebhetri, i-anode, kunye ne-electrolyte, iingcali zijolise ekunyuseni ukuzinza kwe-thermal yeebhetri ze-lithium-ion.Ngokomzekelo, abaphandi baye bazama ukongeza izongezo ze-flame-retardant kwi-electrolyte yebhetri, ngokufanelekileyo ukunciphisa umngcipheko wokusasazeka komlilo.
Enye indlela ethembisayo kukuphunyezwa kweenkqubo zolawulo lwebhetri ezikumgangatho ophezulu (BMS) ezithi gqolo zibeke iliso kwaye zilawule iimeko zokusebenza kwebhetri.Ezi nkqubo zinokubona ukuguquguquka kweqondo lobushushu, izitenxo zombane, kunye nezinye iimpawu ezilumkisayo zokubaleka okunokwenzeka kobushushu.Ngokusebenza njengenkqubo yokulumkisa kwangethuba, i-BMS inokunciphisa umngcipheko womlilo ngokuqalisa amanyathelo okhuseleko afana nokunciphisa amaxabiso okutshaja okanye ukuvala ibhetri ngokupheleleyo.
Ngaphezu koko, kukho ugxininiso olukhulayo ekuphuhliseni iinkqubo ezisebenzayo zokucima umlilo ezilungiselelwe ngokukodwa iibhetri ze-lithium-ion.Izindlela zokucima umlilo zendabuko, ezifana namanzi okanye i-foam, azinakufaneleka ukucima imililo ye-lithium-ion yebhetri, njengoko inokunyusa imeko ngokubangela ukuba ibhetri ikhulule izinto ezinobungozi.Ngenxa yoko, abaphandi basebenza kwiinkqubo ezintsha zokucima umlilo ezisebenzisa izixhobo ezikhethekileyo zokucima umlilo, ezifana ne-inert gases okanye i-powders eyomileyo, ekwazi ukucima umlilo ngokufanelekileyo ngaphandle kokonakalisa ibhetri okanye ukukhulula i-byproducts enetyhefu.
Ukongeza kwinkqubela phambili yezobuchwepheshe, imigangatho yokhuseleko oluqinileyo kunye nemimiselo idlala indima ebalulekileyo ekuqinisekiseni ukukhuselwa komlilo kwiibhetri ze-lithium-ion.Oorhulumente nemibutho yehlabathi bazama ngamandla ukuseka imigaqo engqongqo yokhuseleko ebandakanya ukuyilwa kweebhetri, ukwenziwa, ukuthuthwa nokulahlwa kwebhetri.Le migangatho ibandakanya iimfuno zokuzinza kwe-thermal, uvavanyo lokuxhatshazwa, kunye namaxwebhu okhuseleko.Ngokuthobela le mimiselo, abavelisi banokuqinisekisa ukhuseleko kunye nokuthembeka kweemveliso zabo zebhetri.
Ngaphezu koko, ulwazi loluntu kunye nemfundo malunga nokuphathwa ngokufanelekileyo kunye nokugcinwa kweebhetri ze-lithium-ion zibaluleke kakhulu.Abathengi kufuneka baqonde imingcipheko eyayanyaniswa nokungaphathwa kakuhle okanye ukusetyenziswa kakubi, njengokugqobhoza ibhetri, ukuyibeka esichengeni sobushushu obugqithisileyo, okanye ukusebenzisa iitshaja ezingagunyaziswanga.Izenzo ezilula ezifana nokuphepha ukutshisa kakhulu, ukungayibeki esichengeni ibhetri ekukhanyeni kwelanga, kunye nokusebenzisa iintambo zokutshaja ezivunyiweyo zinokuhamba indlela ende ekuthinteleni izehlo ezinokubakho zomlilo.
Uguqulo logcino lwamandla luphenjelelwa yiiibhetri ze-lithium-ionibambe amandla amakhulu okuguqula amashishini amaninzi kunye nokuququzelela utshintsho olusingise kwimithombo yamandla aluhlaza.Nangona kunjalo, ukuphakamisa ngokupheleleyo oku kunokwenzeka, ukhuseleko lomlilo kufuneka luhlale luphambili.Ngophando oluqhubekayo kunye nezinto ezintsha, ezidityaniswa nemigangatho engqongqo yokhuseleko kunye nokuziphatha kwabathengi abanoxanduva, sinokuqinisekisa ukudityaniswa okukhuselekileyo nokuzinzileyo kweebhetri ze-lithium-ion kubomi bethu bemihla ngemihla.
