Kuthiwani uma singase sisebenzise kabusha amandla asele kumabhethri alahliwe?Manje ososayensi bayazi ukuthi kanjani

Amabhethri e-alkaline kanye ne-carbon-zinc avamile kumishini eminingi ezisebenza yona.Nokho, uma ibhethri seliphelile, ngeke lisakwazi ukusetshenziswa futhi liyalahlwa.Kulinganiselwa ukuthi cishe amabhethri ayizigidi eziyizinkulungwane eziyi-15 akhiqizwa futhi adayiswa emhlabeni wonke unyaka ngamunye.Iningi layo ligcina selisendaweni yokulahla imfucumfucu, kanti amanye agaywa abe izinsimbi ezibalulekile.Nokho, nakuba lawa mabhethri engasebenziseki, ngokuvamile anenani elincane lamandla asele kuwo.Eqinisweni, cishe ingxenye yawo iqukethe amandla afinyelela kwangu-50%.
Muva nje, ithimba labacwaningi abavela e-Taiwan baphenye ukuthi kungenzeka yini ukukhipha la mandla kumabhethri alahlwayo (noma ayisisekelo).Ithimba eliholwa nguSolwazi uLi Jianxing waseNyuvesi yase-Chengda e-Taiwan ligxile ocwaningweni lwalo kulesi sici ukuze likhuthaze umnotho oyindilinga wamabhethri alahlwayo.
Ocwaningweni lwabo, abacwaningi bahlongoza indlela entsha ebizwa ngokuthi i-Adaptive Pulsed Discharge (SAPD) engasetshenziswa ukunquma amanani afanele amapharamitha amabili abalulekile (imvamisa ye-pulse kanye nomjikelezo womsebenzi) ukuthi: Le parameter inquma ukukhishwa kwamanje.ibhethri elahliwe.Ibhethri.Kalula nje, i-high discharge current ihambisana nenani elikhulu lamandla abuyiselwe.
"Ukuthola amandla amancane asele kumabhethri asendlini kuyisiqalo sokunciphisa imfucuza, futhi indlela ehlongozwayo yokuthola amandla iyithuluzi eliphumelelayo lokusebenzisa kabusha inani elikhulu lamabhethri alahliwe," kusho uProfesa Li, echaza isizathu socwaningo lwakhe. .ishicilelwe ku-IEEE Transactions on Industrial Electronics.
Ngaphezu kwalokho, abacwaningi bakhe i-hardware prototype yendlela yabo ehlongozwayo yokubuyisela umthamo osele wephakethe lebhethri elikwazi ukubamba izinhlobo zamabhethri ayisithupha kuya kweziyi-10.Bakwazile ukuthola amandla angu-798–1455 J ngokusebenza kahle kokululama okungama-33–46%.
Kumaseli ayinhloko akhishiwe, abacwaningi bathola ukuthi indlela yokukhishwa kwesifunda esifushane (i-SCD) yayinenani eliphakeme kakhulu lokukhishwa ekuqaleni komjikelezo wokukhipha.Kodwa-ke, indlela ye-SAPD ibonise izinga eliphezulu lokukhishwa ekupheleni komjikelezo wokukhipha.Uma usebenzisa izindlela ze-SCD kanye ne-SAPD, ukutholwa kwamandla kungama-32% kanye nama-50%, ngokulandelana.Kodwa-ke, lapho lezi zindlela zihlanganiswa, amandla angama-54% angatholakala.
Ukuze sihlole ukuthi kungenzeka yini indlela ehlongozwayo, sikhethe amabhethri amaningana alahliwe e-AA ne-AAA ukuze athole amandla.Ithimba lingakwazi ukubuyisela ngempumelelo u-35–41% wamandla kumabhethri asetshenzisiwe."Nakuba kubonakala kungenanzuzo ekusebenziseni amandla amancane ebhethri elilahliwe elilodwa, amandla atholiwe akhula kakhulu uma kusetshenziswa inani elikhulu lamabhethri alahliwe," kusho uProfesa Li.
Abacwaningi bakholelwa ukuthi kungase kube khona ubudlelwano obuqondile phakathi kokusebenza kahle kokwenza kabusha kanye namandla asele amabhethri alahliwe.Mayelana nomthelela wesikhathi esizayo womsebenzi wabo, uProfesa Lee uphakamisa ukuthi “amamodeli athuthukisiwe nama-prototypes angasetshenziswa ezinhlotsheni zamabhethri ngaphandle kwe-AA ne-AAA.Ngokungeziwe ezinhlotsheni ezahlukahlukene zamabhethri ayisisekelo, amabhethri angashajwa njengamabhethri e-lithium-ion nawo angafundwa.ukunikeza ulwazi olwengeziwe mayelana nomehluko phakathi kwamabhethri ahlukene."
