Ugxininiso: Ipakethe yebhetri ye-lithium-ion ifuna ukomeleza ukuphinda kusetyenziswe izixhobo kunye nolawulo lomjikelo wobomi. Ukuphinda kusetyenziswe ileli yeepakethi zebhetri ye-lithium-ion ibisoloko iyingxaki ekugxilwe kuyo, kwaye akukho sisombululo sipheleleyo okwangoku. Ezinye iingcali zibonise ukuba ilizwe lam kufuneka limisele ulawulo lomjikelo wobomi obugcweleyo benkqubo yebhetri yogcino lwamandla kunye nokuqinisa amandla, ukomeleza ukusetyenziswa kwezixhobo ezibanzi, kunye nokukhuthaza uluntu oluzinzileyo ngokudibeneyo.

Okwangoku, urhulumente ugxininisa ukulawulwa kokulawulwa kwebhetri ye-lithium enamandla, ukuseka ukusetyenziswa kwenyathelo le-lithium yebhetri eguquguqukayo kunye nenkqubo yolawulo lokubuyisela kwakhona, ngoko ke izixhobo aziyi kuchithwa. Iimoto zombane, ii-smartphones, izacholo ezikrelekrele, iirobhothi ezitshayelayo . Iimveliso ze-elektroniki ziye ngokuthe ngcembe zibe yimfuneko.

Ngale ndlela, amandla kunye neebhetri zokugcina amandla zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zemveliso kunye nobomi. Ngethuba le nkqubo, ukhuseleko lweebhetri ze-lithium-ion ezinkulu ezinomthamo omkhulu, ukubuyiswa kunye nokusetyenziswa kweleli yeebhetri zenkunkuma, njl. zingqwalasela yengqwalasela yoluntu.

Ipakethe yebhetri yeLithium-ion iza kusonjululwa yiChemistry yelizwe lam kunye nePhysical Power Industry Association, ilizwe lam libe yeyona ndawo isebenzayo yeepakethe zebhetri zelithium-ion zelizwe. Ngo-2016, imarike yebhetri yelithium-ion yelizwe lam yayimalunga ne-111.5 yeebhiliyoni zeeyuan, kwaye imfuno yebhetri ye-lithium-ion eguqukayo yayingama-60.

I-5 yeebhiliyoni zeeyuan, inyuke ngama-65.8% unyaka nonyaka. Kwi-2020, imfuno yebhetri ye-lithium eguqukayo iya kufikelela kumaxesha angama-5 kwi-2015.

Nangona imveliso yebhetri yelizwe lam ilihlabathi, inzuzo yemveliso yeyunithi ingaphantsi kuneJapan. Isizathu sokuba imveliso yebhetri yelizwe lam inesivuno esiphezulu, ingeniso ephantsi, ngenxa yokuswela amalungelo epropathi enomgangatho ophezulu wokuqonda. ilizwe lam linomsantsa othile phakathi kwezinto ezisisiseko kunye namacandelo eepakethe zebhetri ye-lithium-ion kunye nenkqubo yokuvelisa.

Ubomi bebhetri yemoto yamandla amatsha yeyona nto iphambili kwinqanaba lebhetri ye-lithium-ion. Idatha ibonisa ukuba kwi-2017, isiqinisekiso semoto entsha yelizwe lam yi-1.53 ​​yezigidi, ekulindeleke ukuba idlule amanqaku ezigidi ezi-5 ngo-2020.

Kodwa uninzi lwebhetri yemoto yombane, ayinakuxhasa isithuthi ukusuka eShanghai ukuya eHefei. Ipakethe yebhetri ye-lithium-ion emva kokusetyenziswa ishiye iingozi ezininzi ezifihliweyo. Usihlalo olawulayo wentlanganiso, uProfesa Xiamen University, Sun Shigang, academician Chinese Academy of Sciences, wathi inkunkuma lithium-ion iibhetri ikhona kunye nezinye iingozi zokhuseleko, kwaye ungcoliseko lokusingqongileyo ungcoliseke kakhulu.

Indlela yokulawula umjikelezo wobomi obupheleleyo ifuneka ngokukhawuleza ukwenza kwimbono, "Ulawulo oluPheleleyo loMjikelo woBomi" kulindeleke ukuba lube yindlela efanelekileyo yokusombulula iingxaki ezininzi zeepakethi zebhetri ze-lithium-ion. Ulawulo lomjikelo wobomi obugcweleyo lunokwahlulwa lube ngamanqanaba amathathu emveliso yoyilo, ukusetyenziswa kunye nokusetyenziswa kweleli kunye nokuphinda kusetyenziswe. Ngo-2016, ifowuni ye-Samsung Galaxy Note7 yazisa kuphela ngaphezu kwenyanga, kwihlabathi, ngaphezu kwe-30 ukuqhuma kunye neengozi zomlilo ezibangelwa yiziphene zebhetri.

Ukuze uthintele ingozi enjalo, phucula kuyilo lwebhetri. Kwindlela yoyilo, imodeli isetwa yimodeli ukuseta iiparitha zoyilo ezahlukeneyo kwaye emva koko kwimveliso yovavanyo, kwaye umgca wemveliso unokujikeleza uzinzo kunye nokhuseleko lwemveliso yomgca wemveliso, umgca wovavanyo, ukuhlanganiswa kweengcingo ezintathu zomgca wovavanyo oluphakathi kunye nomgca wokuvelisa ubuninzi Ukutshintsha ngokukhawuleza. Uvavanyo oluchanekileyo kunye nokuqikelelwa kwemeko yebhetri ye-lithium-ion sisitshixo sokusetyenziswa ngokufanelekileyo kweenkqubo zamandla.

Ngakolunye uhlangothi, inkqubo yebhetri yeeyure zenkonzo iyafuneka ukuba ivavanye kwaye iqikelele ukusebenza kwezigaba zayo ezahlukeneyo zobomi; kwelinye icala, kuyimfuneko ukuvavanya ukusebenza kokhuseleko phantsi komjikelo wobomi obupheleleyo benkqubo yebhetri. Kwaye ileli kulindeleke ukuba ikhuthaze uqoqosho lwesetyhula kunye neebhetri zenkunkuma. Ngokomzekelo, malunga nepakethi yebhetri ye-lithium ion ephantsi, ingasetyenziselwa kwiimoto eziphantsi kwesantya kunye nokugcinwa kwamandla.

Emva kokuba umthamo uphelile, ukuchithwa kokutyumza kunokwenziwa, kwaye izinto ezisebenzayo zinokukhutshwa. Okwangoku, abaphandi baye benza inkqubela ethile kwinkqubo yokubuyisela iipakethi zebhetri ye-lithium-ion, kwaye baye baphuhlisa iinkqubo ezintsha kunye ne-granks engafanelekanga. Le nkqubo isebenze ngakumbi kwaye iphantsi, enokuthi isebenzise ngokupheleleyo ukushisa kwayo kunye nokuthintela, kunye nokuphucula izibonelelo ze-lithium ezihlaziyiweyo, kunye nokukhuselwa kwendalo kunye neenzuzo zoqoqosho.

Ukongamela olusebenzayo lufuneka ngokukhawuleza ukwazisa kwimbono, ukuveliswa kwebhetri ye-lithium-ion yangoku, ukusetyenziswa, ukuphinda kusetyenziswe, njl., isimo sokulawula sisekwimeko yokuphazamiseka. Kwinqanaba loyilo kunye nokuveliswa kwebhetri yangaphambili, ii-arhente ezifanelekileyo azizange ziseke imigangatho kunye nokulawula okusebenzayo.

Uyilo lwebhetri ye-lithium-ion lusisiseko sokuphumeza ukubola kwezinto eziluhlaza zokukhusela indalo. Urhulumente kufuneka acacise inkqubo yomthetho efanelekileyo, kwaye alungelelanise uxanduva lokubuyisela kunye nenqanaba lokusetyenziswa kwakhona emva kokusetyenziswa kweemveliso zemveliso. Kwangaxeshanye, isebe lolawulo kufuneka lomeleze ukulawulwa kweemarike, landise ulawulo lwesebe, kwaye liphucule ngakumbi indlela yokongamela yeenkqubo zomjikelo wobomi obupheleleyo.

Ibhetri ye-Lithium-ion ibhetri yokugcina amandla okukhusela okusingqongileyo ibe yimfuno yophuhliso kunye nophuhliso lobugcisa kunye noqoqosho, iingxaki zamandla kunye nokusingqongileyo ziye zanda kakhulu, kwaye imboni yamandla engenakuphazamiseka kufuneka iphuhlise "eluhlaza, ukukhuselwa kwendalo". Ukusuka kwiindlela zomgaqo-nkqubo welizwe lam, amazwe akhuphe imigaqo-nkqubo eyahlukeneyo yokunyusa inkxaso kuqoqosho oluphantsi kwekhabhoni ehambelana nokusingqongileyo, ngokungathandabuzekiyo lithuba elihle le-lithium-ion ibhetri ephantsi koqoqosho lokusingqongileyo oluluhlaza. Iipakethi zebhetri zeLithium-ion zidibene nabavelisi basekhaya, ukuhambelana, ukuzinza, ukhuseleko, ukhuseleko lokusingqongileyo, kunye nobomi be-loop, njl.

, nazo zinomtsalane kakhulu kubakhiqizi abasezantsi.
