Iibhetri zealkaline kunye nekhabhoni-zinc zixhaphakile kwizixhobo ezininzi ezizisebenzelayo.Nangona kunjalo, xa ibhetri iphelile, ayinakuphinda isetyenziswe kwaye ilahlwe kude.Kuqikelelwa ukuba malunga ne-15 yeebhiliyoni zeebhetri zenziwa kwaye zithengiswa kwihlabathi jikelele ngonyaka.Uninzi lwawo luphelela kwiindawo zokulahla inkunkuma, kwaye ezinye zilungiswa zibe ziintsimbi ezixabisekileyo.Nangona kunjalo, ngelixa ezi bhetri zingasebenziseki, zihlala zinenani elincinci lamandla asele kuzo.Enyanisweni, malunga nesiqingatha sazo ziqulethe ukuya kwi-50% yamandla.
Kutshanje, iqela labaphandi abavela eTaiwan baphanda ithuba lokukhupha la mandla kwiibhetri ezilahlwayo (okanye eziphambili).Iqela elikhokelwa nguNjingalwazi uLi Jianxing ovela kwiYunivesithi yaseChengda eTaiwan ligxininise uphando lwalo kulo mba ukwenzela ukukhuthaza uqoqosho lwesetyhula kwiibhetri zenkunkuma.
Kuphononongo lwabo, abaphandi bacebisa indlela entsha ebizwa ngokuba yi-Adaptive Pulsed Discharge (SAPD) enokuthi isetyenziswe ukumisela amaxabiso afanelekileyo kwiiparamitha ezimbini eziphambili (i-pulse frequency kunye nomjikelo womsebenzi) ukuba: Le parameter imisela ukukhutshwa kwangoku.ibhetri elahliweyo.Ibhetri.Ukubeka nje, ukukhutshwa okuphezulu kwangoku kuhambelana nomthamo omkhulu wamandla afunyenweyo.
"Ukubuyisela inani elincinci lamandla ashiyekileyo kwiibhetri zendlu sisiqalo sokunciphisa inkunkuma, kwaye indlela ecetywayo yokubuyisela amandla sisixhobo esisebenzayo sokuphinda sisebenzise isixa esikhulu seebhetri eziphambili ezilahliweyo," utshilo uNjingalwazi uLi, echaza ingqiqo yophando lwakhe. .ipapashwe kwi-IEEE Transactions kwi-Industrial Electronics.
Ukongeza, abaphandi bakhe iprototype ye-hardware yendlela ecetywayo yokubuyisela umthamo oseleyo webhetri ekwaziyo ukubamba iintlobo ezintandathu ukuya kwi-10 ezahlukeneyo zeebhetri.Bakwazile ukubuyisela i-798-1455 J yamandla ngokusebenza kakuhle kokubuyisela kwi-33-46%.
Kwiiseli eziziiprayimari ezikhutshiweyo, abaphandi bafumanisa ukuba indlela yokukhutshwa kweesekethe ezimfutshane (SCD) yayinezinga eliphezulu lokukhutshwa ekuqaleni komjikelezo wokukhupha.Nangona kunjalo, indlela ye-SAPD ibonise izinga eliphezulu lokukhupha ekupheleni komjikelezo wokukhupha.Xa usebenzisa iindlela ze-SCD kunye ne-SAPD, ukubuyiswa kwamandla yi-32% kunye ne-50%, ngokulandelanayo.Nangona kunjalo, xa ezi ndlela zidityanisiwe, i-54% yamandla inokufunyanwa kwakhona.
Ukuqhubela phambili ukuvavanya ukwenzeka kwendlela ecetywayo, sikhethe iibhetri ezininzi ezilahliweyo ze-AA kunye ne-AAA zokubuyisela amandla.Iqela linokubuyisela ngempumelelo i-35-41% yamandla kwiibhetri ezichithiweyo."Nangona kubonakala ngathi akukho nzuzo ekusebenziseni umbane omncinci kwibhetri enye elahliweyo, amandla afunyenweyo akhula kakhulu ukuba kusetyenziswe inani elikhulu leebhetri ezilahliweyo," watsho uNjingalwazi uLi.
Abaphandi bakholelwa ukuba kunokubakho ubudlelwane obuthe ngqo phakathi kokusebenza ngokufanelekileyo kunye nomthamo oseleyo weebhetri ezilahliweyo.Ngokuphathelele ifuthe lekamva lomsebenzi wabo, uNjingalwazi uLee ucebisa ukuba “iimodeli eziphuhlisiweyo kunye neeprototypes zinokusetyenziswa kwiintlobo zebhetri ngaphandle kwe-AA kunye ne-AAA.Ukongeza kwiindidi ezahlukeneyo zeebhetri eziphambili, iibhetri ezinokuphinda zitshajwe njengeebhetri ze-lithium-ion nazo zinokufundwa.ukunika ulwazi olungakumbi ngomahluko phakathi kweebhetri ezahlukeneyo.
