18650 Ayizukuhlawulisa

Uhlobo lwebhetri ye-18650-lithium yenye yeebhetri ze-lithium ezisetyenziswa ngokuqhelekileyo kwiimveliso ezahlukeneyo ze-elektroniki. Eyaziwa ngokubanzi njengeebhetri ze-lithium polymer, ezi ziibhetri ezinokutshajwa kwakhona. Uhlobo lweseli lusetyenziswa ngokubanzi njengeseli kwipakethi yebhetri yekhompyuter. Nangona kunjalo, ngamanye amaxesha sifumana ukuba ibhetri ye-18650-lithium-ion ayinakuhlawulisa xa uyisebenzisa. Makhe sijonge ukuba kutheni ibhetri ye-18650 ayinakuhlawulisa kunye nendlela yokuyilungisa.

Ziziphi izizathu zokuba ibhetri ye-18650 ayinakuhlawuliswa

Ukuba ibhetri yakho ye-18650 ayifuni kuhlawuliswa, izizathu ezininzi zinokuba yibangela. Okokuqala, kusenokwenzeka ukuba unxibelelwano lwe-electrode yebhetri ye-18650 lumdaka, lubangela ukuxhathisa okukhulu kakhulu kunye nokuhla kwamandla ombane. Oku kubangela ukuba umamkeli acinge ukuba inentlawulo epheleleyo kungoko iyeke ukutshaja.

Esinye isizathu esinokwenzeka sokungahlawulisi kukungaphumeleli kwesekethe yokutshaja yangaphakathi. Oku kuthetha ukuba ibhetri inokutshajwa ngokuqhelekileyo. Isekethe yangaphakathi yebhetri inokuthi ingasebenzi ngenxa yebhetri ekhutshwe ngaphantsi kwe-2.5 yombane.

Uyilungisa njani ibhetri ye-18650 engayi kuhlawulisa?

Xa ibhetri ye-lithium 18650 ikhupha ngokunzulu, i-voltage ihlala ihamba ngaphantsi kwe-2.5 volts. Uninzi lwezi bhetri akunakwenzeka ukuvuselela xa amandla ombane angaphantsi kwe-2.5 volts. Kule meko, isiphaluka sokukhusela sivala ukusebenza kwangaphakathi, kwaye ibhetri iya kwimodi yokulala. Kule meko, ibhetri ayinamsebenzi kwaye ayikwazi ukuvuswa nakwiitshaja.

Kweli nqanaba, kufuneka unike intlawulo eyaneleyo kwiseli nganye enokunyusa amandla ombane aphantsi ukuyinyusa ibe ngaphezulu kwe-2.5 volts. Emva kokuba oku kwenzeke, isiphaluka sokukhusela siya kuphinda siqalise umsebenzi walo kwaye sinyuse i-voltage ngokutshaja rhoqo. Le yindlela onokuyilungisa ngayo ibhetri ye-lithium ye-18650 ephantse yafa.

Ukuba i-voltage yebhetri ingu-zero okanye iphantse i-zero, oku kubonisa ukuba i-membrane yangaphakathi yokukhusela i-thermal ikhutshiwe, idibana nomphezulu webhetri. Oku kubangela ukuba kusebenze uhambo olugqithisayo kwaye luvela ikakhulu ngenxa yokunyuka koxinzelelo lwangaphakathi kwibhetri.

Uya kulungisa ngokubuyisela i-membrane, kwaye ibhetri iya kuphila kwaye iqalise ukuvuma ukuhlawulwa. Nje ukuba i-terminal voltage inyuke, ibhetri iya kuthatha intlawulo, kwaye ngoku ungayifaka kwintlawulo eqhelekileyo kwaye ulinde ukuba ihlawulise ngokupheleleyo.

Namhlanje, ungazifumana iitshaja ezinophawu lokuvuselela ibhetri ephantse yafa. Ukusebenzisa ezi tshaja kunokonyusa ngokufanelekileyo i-voltage ephantsi ye-18650 lithium ibhetri kwaye kubangele isekethe yokutshaja yangaphakathi eleleyo. Oku kwandisa imisebenzi yepropati ngokufaka ngokuzenzekelayo umbane omncinci wokutshaja kwisiphaluka sokukhusela. Itshaja iphinda iqalise umjikelo wokutshaja osisiseko wakuba umbane weseli ufikelele kwixabiso lomqobo. Unako kwakhona ukuhlola itshaja kunye nentambo yokutshaja ngawo nawuphi na umba.

Okukwintsusa

Nantso ke unayo. Siyathemba ukuba ngoku uyasiqonda isizathu sokuba ibhetri yakho ye-18650 ingahlawulisi kunye nendlela yokuyilungisa. Ngelixa kukho i-18650-ibhetri yezizathu ezininzi zokuba kutheni ibhetri ye-18650-lithium ingahlawuli, eyona nto iphambili kukuba ayihlali ngokusisigxina nakwiimeko ezifanelekileyo. Ngentlawulo nganye kunye nokukhutshwa, amandla abo okuhlawula ayancipha ngenxa yokwakhiwa kweekhemikhali zangaphakathi. Ke ngoko, ukuba ibhetri yakho ifikelele esiphelweni sobomi bayo, ekuphela kwenketho iya kuba endaweni yeyunithi yebhetri.
