I-Watma iye yahlola ukusetyenziswa kwesibini kwebhetri ye-lithium-ion ngo-2012, esebenzisa ibhetri ye-lithium-ion yemoto yombane edla umhlalaphantsi, kwaye yakha i-3MW i-lithium ye-iron phosphate ion ibhetri yokugcina amandla. Ngokufanayo, ukusuka kwi-2012 Qala utyalo-mali kwiibhetri ze-yuan ezintathu. Ngokutsho kophuhliso lwezithuthi zamandla amatsha, kuqikelelwa ukuba ngo-2020, iimoto zombane ezicocekileyo kunye neenqwelo ze-plug-in hybrid ziye zafikelela kwizigidi ezi-2, kunye neeyunithi ezingaphezu kwezigidi ezi-5.

Ngaphantsi kwendawo enkulu eyongeziweyo, kunye nokuphela kobomi bebhetri ye-lithium-ion, ibhetri ye-lithium ion yamandla kwisithuthi sombane iya kufakwa kwinani elikhulu, indlela ezi bhetri zijongene ngayo nengxaki enkulu ejongene neshishini, kunye nendlela i-Watma ecwangcisa ngayo? Inkqubo yokurisayikilisha ibhetri kudala ingusekela mphathi jikelele we Shenzhen Watma Battery Co., Ltd. (I-Institute Dean) uRao Minmin uthe ekusungulweni kwenethiwekhi yokuqala yombane, eqinisweni, i-Watma sele ihlolisise i-lithium enamandla kwi-2012.

Indlela, indlela yebhetri ye-ion, usebenzisa i-lithium-ion yemoto yombane ibhetri ye-lithium-ion, yakha i-3MW i-lithium ye-iron phosphate i-ion ibhetri yokugcina amandla ebhetri, ibeka isiseko sorhwebo lwebhetri yokugcina amandla enkunkuma. Kwangaxeshanye, i-Watma ikwaphuhlise ngamandla iimveliso zokugcina amandla kwinkqubo yokutyhala ibhetri ye-lithium-ion entsha yesithuthi samandla. Ukongeza kuphuhliso lwesikhululo samandla okugcina amandla, i-Watma iye yaphuhlisa ngempumelelo i-1200kwh, 750kwh, 640kWh tram yokuzalisa ehambayo (esetyenziselwa izithuthi zombane, umthamo wokugcina amandla, njl.

). Kwixesha elizayo, kuqwalaselwa ukusebenzisa inkunkuma eguquguqukayo iibhetri ze-lithium-ion kwiimoto ezongezelelweyo ezihambayo, kwaye uhlolisise ukusetyenziswa kwebhetri ye-lithium ion yamandla enkunkuma kwinkqubo yokugcina amandla. Kwelinye icala, i-Watma iya kusebenzisa itekhnoloji yemveliso ephucukileyo, inqanaba elifutshane, ukuphinda isetyenziswe okusebenzayo kwezinto ezifana ne-nickel, i-cobalt, i-manganese, i-lithium ebhetrini, emva koko ngemodeli yenkampani yokuqala "yokujikeleza okujikelezayo" kunye neyona ndawo iphambili yehlabathi "uyilo lokumisa imveliso" ubugcisa, lungelelanisa icandelo lezinto ezininzi ngokudibanisa itekhnoloji, ukudibanisa itekhnoloji kunye nokulungelelanisa itekhnoloji. "Ujikelezo olujikelezayo" ukusuka kwinkunkuma yebhetri ukuya kwimathiriyeli yebhetri, ngaloo ndlela ivelisa ibhetri ukusuka kwimveliso, ukusetyenziswa ukuya ekubuyiselweni kwayo yonke imijikelezo ye-Organic indibaniselwano.

Ukuthathela ingqalelo ukhuseleko lwebhetri kunye noxinaniso lwamandla lokuhlola itekhnoloji yebhetri yeeyuan ezintathu ukusukela ngo-2008, iWatma iqokelele ngaphezulu kweminyaka esi-7 yamava anxulumene nokusebenza kwemoto yamandla, ixhotyiswe ngebhetri yeWatma ngaphezulu kwe-30,000 yaseTaiwan iseti, imileage yokusebenza enye yi-430,000 km. Ngokubhekiselele kwintlawulo ekhawulezayo yebhetri, ibhetri ye-ion ye-Watema phosphate nayo ihlawuliswe imizuzu eyi-10 ukutshaja amandla angama-80%, kwaye isetyenziswe kuluhlu olukhulu. Okufanayo kusekelwe kukhuseleko, isiseko esikhoyo ngoku zonke iziseko zeWatma yibhetri ye-ion ye-lithium, kodwa ngokubhekiselele kwizinto ezintathu ze-yuan, uRao Minmin uthe inzuzo yoxinano lwamandla ngokwenene yiWatma.

Ukususela kwi-2012, ndaqala ukutyalomali kuphando kunye nophuhliso iminyaka emininzi, kodwa andizange ndikhuthaze ngokubanzi, kwaye ndiya kuba noluhlu olubanzi lokuphucula. Ngokukwanjalo, waphinda wathi iWatma isebenzisa imathiriyeli edibeneyo njengebhetri eqinisekileyo kunye nesixhobo esingalunganga se-electrode ukukhulisa amandla ebhetri amalunga nama-20%. Okwangoku, i-Watema phosphate ion battery monomer energy density inokufikelela kwi-180-200 kWh/kg, 100KWh/kg inokufumaneka emva kokuba ibhetri iseti.

Ngokubhekiselele kukhuseleko, ibhetri ye-lithium-ion yamandla kaWatema eveliswa kwi-monomer, imodyuli ukuya kwinkqubo yeqela kude kube ngumsebenzi ofakiweyo, yenza uluhlu olupheleleyo lokufumanisa, ngeqonga elikhulu ledatha, ukubeka iliso kwimoto nganye. Okwangoku, i-Watma cylindrical ferric lithium ion ibhetri yesakhiwo sazisa i-tube yeziko lokungena umoya, ukuxazulula ingxaki yebhalansi yoxinzelelo lwangaphakathi lwebhetri, ukuthintela ukuqhuma kwebhetri; iivalvu ezintsha zokhuseleko kumnqwazi odityanisiweyo, ulawulo olusebenzayo loxinzelelo lwangaphakathi lwebhetri kukhuseleko oluqhelekileyo Ngaphakathi kwexabiso loluhlu, thintela umngcipheko wokudubula; ipakethe yebhetri isebenzisa iiphaneli ezidibeneyo eziyilwe ngokukodwa kunye neesekethe zokukhusela ze-PCB, nokuba indawo yokusetyenziswa kwebhetri ivumela zonke iibhetri kwindawo efanayo, nokuba ukulungelelaniswa kwandisa ukuxhathisa ukwenza ibhetri. Umthwalo othwalwayo uyafana, kwaye kukho umahluko wokusingqongileyo phakathi kwebhetri.

Ukongeza, ibhetri ye-Watma ephantsi yobushushu ayiphumelelanga kuphela kwi-Xinjiang Urumqi, kodwa idlulise igunya leSebe lezoLwazi lweSebe leMichiza yeFiziksi yaMandla eMgangathweni weMgangatho weMveliso kunye noHlolo, ebonisa ukuba ummandla osemantla welizwe lam ukhuthaza iimoto zombane ezicocekileyo zinesisombululo sokuqala soBuchwephesha. Ukuqhawula umda wokutshaja kunye nokukhutshwa okungaphantsi kwama-20 degrees ngaphezu kwe-zero, kunokufumaneka kwi-minus 35 degrees yokukhutshwa okuqhelekileyo kunye ne-zero 20 degrees yokutshaja okuqhelekileyo. Ekugqibeleni, xa ndithetha ngomgangatho omtsha welizwe webhetri, uRao Dingyi ukholelwa ukuba ukuphunyezwa komgangatho omtsha welizwe longeze ubushushu obuphezulu kunye nobushushu obuphantsi kunye nokucwiliswa kwemodyuli yeseli yebhetri, enyanisweni, oku kuphucula umgangatho wokufikelela kwebhetri, iBattery Safety Demand.

Kodwa uphuhliso olusempilweni lweshishini lukwaluncedo, kwaye nokusetyenziswa komgangatho weshishini nako kukhulu kakhulu.
