Njengamanje, amabhethri e-lithium asetshenziswa kakhulu futhi asetshenziswa kabanzi kumadivayisi ahlukahlukene wedijithali anjengezincwadi zokubhalela, amakhamera edijithali namakhamera wevidiyo edijithali. Ngaphezu kwalokho, banamathemba abanzi ezimotweni, eziteshini ezisesimweni seselula, kanye neziteshi zamandla ezitoreji zamandla. Kulokhu, ukusetshenziswa kwamabhethri akusabonakali ngedwa njengasemasha, kepha ngaphezulu ngendlela yochungechunge noma amaphakethe ebhethri afanayo.
Umthamo kanye nempilo yephakethe lebhethri akuhlobene nebhethri ngalinye elilodwa, kepha kuhlobene nokuvumelana phakathi kwebhethri ngalinye. Ukungaguquguquki okumpofu kuzodonsa kakhulu ukusebenza kwephakethe lebhethri. Ukuvumelana kokuzikhipha kuyingxenye ebalulekile yezinto ezithonya. Ibhethri elinokuzidela okungahambisani lizoba nomehluko omkhulu ku-SoC ngemuva kwesikhathi sokugcina, okuzothinta kakhulu amandla alo nokuphepha.
Kungani ukuzenzela ukuzenzela?
Lapho ibhethri livulekile, ukusabela okungenhla akwenzeki, kepha amandla asazokwehla, okubangelwa ukuzikhipha kwebhethri. Izizathu eziphambili zokuzenzela ukuzila:
a. Ukuvuza kwe-elektroni yangaphakathi okubangelwa ukufakwa kwe-electron kwe-electron ye-electrolyte noma eminye imibuthano emifushane yangaphakathi.
b. Ukuvuza kukagesi kwangaphandle ngenxa yokufakwa kabi kwezimpawu zebhethri noma ama-gaskets noma ukumelana okunganele phakathi kwamagobolondo okuhola kwangaphandle (abaqhubi bangaphandle, umswakama).
c. I-Electrode / Electrolyte yokuphendula, njengokugqwala kwe-anode noma ukuncishiswa kwe-cathode ngenxa ye-electrolyte, ukungcola.
d. Ukubola okuyingxenye kwezinto ezisebenzayo ze-electrode.
e. Ukudlula kwama-electrodes ngenxa yemikhiqizo yokubola (ama-insersops kanye namagesi athunyelwe ama-adsorbed).
f. I-electrode igqokwa ngomshini noma ukumelana phakathi kwe-electrode kanye nomqoqi wamanje iba nkulu.
Ithonya Lokuzenzisa
Ukuzikhulula kuholela ekutheni kwehle kakhulu ngesikhathi sokugcina.Izinkinga ezimbalwa ezijwayelekile ezibangelwa ukuzimela ngokweqile:
1. Imoto ipakwe isikhathi eside kakhulu futhi ayikwazi ukuqalwa;
2. Ngaphambi kokuba ibhethri lifakwa kwisitoreji, amavoluti nezinye izinto zijwayelekile, futhi kutholakala ukuthi amavolula aphansi noma aze athunyelwa lapho kuthunyelwa;
I-3. Ehlobo, uma i-GPS yemoto ibekwe emotweni, amandla noma isikhathi sokusetshenziswa kuzoba ngokusobala akwanele ngemuva kwesikhathi, noma ngabe kukhanyeke ibhethri
Ukuzikhulula kuholela ekwandiseni umehluko we-SC phakathi kwamabhethri kanye nokuncishiswa kwebhethri yebhethri
Ngenxa yokuzidela okungahambelani kwebhethri, i-Soc yebhethri ebhethri lebhethri izokwehluka ngemuva kokugcina, futhi ukusebenza kwebhethri kuzokwehla. Amakhasimende avame ukuthola inkinga yokuwohloka kokusebenza ngemuva kokuthola iphakethe lebhethri eligcinwe isikhathi esithile. Lapho umehluko we-SOC ufinyelela cishe ama-20%, amandla ebhethri elihlanganisiwe angu-60% ~ 70%.
Ungayixazulula kanjani inkinga yokwehlukahluka komphakathi okukhulu okubangelwa ukuzikhipha?
Simply, kudingeka silinganise kuphela amandla ebhethri bese sidlulisela amandla esitokisini esiphakeme se-voltage esitokisini esisezingeni eliphansi. Kukhona izindlela ezimbili: ukulinganisa nje nokulinganisa okusebenzayo
Ukulingana okungenamqondo ukuxhumanisa ukumelana kokulinganisa ngokufana neseli ngalinye lebhethri. Lapho iseli lifinyelela ngaphezulu kwe-overvoltage kusengaphambili, ibhethri lingakhokhiswa futhi likhokhise amanye amabhethri aphansi aphansi. Ukusebenza kahle kwale ndlela yokulinganisa akuphezulu, futhi amandla alahlekile alahlekile ngendlela yokushisa. Ukulingana kumele kwenziwe kwimodi yokushaja, kanye nokulingana kwamanje kuvame ukuthi i-30MA iye ku-100mA.
Isilinganisi esisebenzayoNgokuvamile zilinganisa ibhethri ngokudlulisela amandla futhi zidlulisela amandla amaseli ane-voltage ngokweqile kumaseli athile anamanzi aphansi. Le ndlela yokulinganisa inokusebenza kahle kakhulu futhi ingalinganiswa kuzo zombili izindleko zokukhipha. Amanje wamanje ukulingana kwayo izikhathi eziningi zikhulu kunokulingana okufana, ngokuvamile phakathi kwe-1a-10a.
