Kutheni iibhetri ze-lithium kunye neepakethe zebhetri ze-lithium zombini zifuna uvavanyo lokuguga kunye nokwaluphala?

Uvavanyo lokuguga kwebhetri yeLithium:
Isigaba sokusebenzisa ipakethe yebhetri ye-lithium ibandakanya ukutshaja kwangaphambili, ukubunjwa, ukuguga, kunye nomthamo oqhubekayo kunye nezinye izigaba. Indima yokuguga kukwenza iipropati kunye nokubunjwa kwe-membrane ye-SEI eyenziwe emva kokutshaja kokuqala okuzinzileyo. Ukuguga kwebhetri ye-lithium kuvumela ukungena kwe-electrolyte kube ngcono, okunenzuzo ekuzinzeni kokusebenza kwebhetri;
Izinto eziphambili ezichaphazela ukusebenza kwepakethi yebhetri ye-lithium zimbini, ezizezi: ukushisa kokuguga kunye nexesha lokuguga. Okubaluleke ngakumbi, ibhetri kwibhokisi yokuvavanya ukuguga ikwimeko etywiniweyo. Ukuba inikwe amandla okuvavanya, idatha evavanyiweyo iya kwahluka kakhulu, kwaye kufuneka iqatshelwe.
Ukuguga ngokubanzi kubhekisa ekubekweni emva kokutshaja okokuqala emva kokuzaliswa kwebhetri. Iyakwazi ukuguga kwiqondo lokushisa okanye ukushisa okuphezulu. Indima yayo kukuzinzisa iipropati kunye nokubunjwa kwe-membrane ye-SEI eyenziwe emva kokutshaja kokuqala. Ubushushu bokwaluphala bungama-25 °C. Ubushushu obuphezulu bobudala buyohluka ukusuka kumzi-mveliso ukuya kumzi-mveliso, amanye ama-38 °C okanye ama-45 °C. Ixesha elininzi lilawulwa phakathi kwe 48 kunye ne 72 iiyure.
Kutheni iibhetri ze-lithium kufuneka zibe mdala:
I-1.Indima kukwenza i-electrolyte ingene kakuhle, enenzuzo ekuzinzeni kokusebenza kwebhetri ye-lithium;
I-2.Emva kokuguga, izinto ezisebenzayo kwizinto ezichanekileyo kunye nezibi ze-electrode ziya kukhawuleza ezinye iziphumo zecala, ezifana nokuveliswa kwegesi, ukuchithwa kwe-electrolyte, njl., Enokukhawuleza ukuzinzisa ukusebenza kwe-electrochemical ye-lithium battery pack;
3.Khetha ukuhambelana kwebhetri ye-lithium emva kwexesha lokuguga. I-voltage yeseli eyenziweyo ayizinzile, kwaye ixabiso elilinganisiweyo liya kuphambuka kwixabiso langempela. I-voltage kunye nokuchasana kwangaphakathi kweseli elidala lizinzile ngakumbi, elilungele ukukhetha iibhetri ezinokuhambelana okuphezulu.
Ukusebenza kwebhetri emva kokuguga okuphezulu kobushushu kuzinzile. Uninzi lwabavelisi bebhetri ye-lithium basebenzisa indlela yokusebenza yobushushu obuphezulu kwinkqubo yokuvelisa, kunye nobushushu obungama-45 °C - 50 °C ngeentsuku ezi-1-3, kwaye ke mayime kwiqondo lokushisa. Emva kokuguga kobushushu obuphezulu, izinto ezimbi ezinokuthi zenzeke kwibhetri ziya kubonakaliswa, njengokutshintsha kombane, utshintsho lobunzima, utshintsho lwangaphakathi lokumelana, njl., Oluvavanya ngokuthe ngqo ukhuseleko kunye nokusebenza kwe-electrochemical kwezi bhetri.
Ngapha koko, ayikokutshaja ngokukhawuleza okukhawulezisa ukuguga kwepakethi yebhetri ye-lithium, kodwa umkhwa wakho wokutshaja! Ukutshaja ngokukhawuleza kuya kukhawulezisa ukuguga kwebhetri. Ngokunyuka kwenani lokusetyenziswa kunye nexesha, ukuguga kwebhetri ye-lithium akunakugwenywa, kodwa indlela efanelekileyo yokugcina inokwandisa ubomi benkonzo yebhetri.
Kutheni kufuneka uvavanyo lokuguga lwepakethi yebhetri ye-lithium?
1.Ngenxa yezizathu ezahlukahlukeneyo kwinkqubo yokuvelisa i-lithium battery PACK, ukuchasana kwangaphakathi, i-voltage, kunye nomthamo weseli iya kuhluka. Ukubeka iiseli ezinomahluko kunye kwipakethi yebhetri kuya kuvelisa iingxaki zomgangatho.
2.Ngaphambi kokuba ipakethe yebhetri ye-lithium ihlanganiswe, umenzi akayazi idatha yokwenyani kunye nokusebenza kwebhetri phambi kokuguga kwebhetri.
3.Uvavanyo lokuguga lwebhetri kukuhlawula kunye nokukhupha ipakethi yebhetri ukuvavanya ukudibanisa kwebhetri, uvavanyo lobomi bebhetri, uvavanyo lwamandla ebhetri. Ukutshaja ibhetri/ukukhupha uvavanyo lweempawu, ukutshajiswa kwebhetri/uvavanyo lokukhupha ukusebenza kakuhle
I-4.Izinga lokuhlawula ngaphezulu / ukukhutshwa ngokugqithiseleyo kovavanyo lokuthwala ibhetri
I-5.Kuphela emva kokuba iimveliso zomenzi ziye zafumana iimvavanyo zokuguga zinokuthi idatha yokwenene yeemveliso ikwaziwa, kunye nemveliso ephosakeleyo ingakhethwa ngexesha elifanelekileyo kwaye liphumelele ukuphepha ukugeleza ezandleni zabathengi.
6.Ukuze ukhuseleke ngcono amalungelo kunye nomdla wabathengi, uvavanyo lokuguga lwebhetri luyinkqubo ebalulekileyo kuye wonke umenzi.
Ukuqukumbela, uvavanyo lokuguga kunye nokuguga kweebhetri ze-lithium kunye neepakethi zebhetri ze-lithium zibalulekile. Ayihambelani kuphela nokuzinza kunye nokulungiswa kokusebenza kwebhetri, kodwa kunye nekhonkco eliphambili lokuqinisekisa umgangatho wemveliso kunye namalungelo omthengi kunye nomdla. Ngenkqubela phambili eqhubekayo yetekhnoloji kunye nokwanda kwemfuno yokusebenza kwebhetri, kufuneka siqhubeke sincamathisela ukubaluleka kwaye ngokuqhubekayo siphucula itekhnoloji yovavanyo lokwaluphala kunye nenkqubo yokukhuthaza uphuhliso olusempilweni lweshishini lebhetri ye-lithium kunye nokubonelela ngezisombululo zamandla ezithembekileyo nezisebenzayo kwiintlobo ezahlukeneyo. izicelo. Masikonwabele lula okuziswe ziibhetri ze-lithium ngelixa sikwafumana amava akhuselekileyo nangcono okusebenzisa. Kwixesha elizayo, sijonge phambili kwiinguqulelo ezininzi kunye neempumelelo kulo mmandla, ukufaka amandla anamandla kuphuhliso kunye nenkqubela phambili yoluntu.
