Ngokutsho kweendaba ezikhutshwe liSebe lezoLwazi lwe-Electronic kwiSebe lezoShishino kunye neTeknoloji yoLwazi nge-10 kaDisemba, ukuze kuqiniswe ngakumbi ulawulo lweshishini lebhetri ye-lithium-ion kunye nokukhuthaza ukuguqulwa nokuphuculwa koshishino kunye nenkqubela phambili yezobuchwepheshe, UMphathiswa wezoShishino kunye nobuChwepheshe boLwazi ulawule okwexeshana “IiMeko zeBattery yeLithium-ion Specifications” kunye “noLawulo lweSibhengezo soShishino lweBattery yeLithium-ion” Amanyathelo ahlaziyiwe kwaye ayabhengezwa. I-"Lithium-ion iBattery Industry Specification Conditions (uHlelo lwe-2018)" kunye "neMiqathango yeThutyana yoLawulo lweZibhengezo zeNkcazelo yoShishino lweBattery yeLithium-ion (uHlelo lwe-2018)" (Isibhengezo seNombolo ye-5, i-2019 yoMphathiswa wezoShishino kunye neTekhnoloji yoLwazi ) iya kubhangiswa ngaxeshanye.
"Iimeko ezisemgangathweni zebhetri yeLithium-ion (2021)" icebisa ukuba ikhokele iinkampani ukunciphisa iiprojekthi zokuvelisa ezithi zandise nje amandla okuvelisa, zomeleze ukuqalwa kweteknoloji, ziphucule umgangatho wemveliso, zinciphise iindleko zemveliso. Iinkampani zebhetri ye-Lithium-ion kufuneka zihlangabezane nale miqathango ilandelayo: kwiRiphabhlikhi yaBantu baseChina ibhaliswe ngokusemthethweni kwaye yasekwa kweli lizwe, kunye nobuntu obusemthethweni obuzimeleyo; imveliso ezimeleyo, ukuthengisa kunye nenkonzo yezakhono zeemveliso ezinxulumeneyo kwishishini lebhetri ye-lithium-ion; Inkcitho ye-R&D ayikho ngaphantsi kwe-3% yengeniso yeshishini engundoqo yenkampani yonyaka, kwaye iinkampani zikhuthazwa ukuba zifumane amaziko e-R&D azimeleyo kwinqanaba lephondo okanye ngaphezulu kweziQinisekiso kumaziko obuchwepheshe okanye amashishini obuchwepheshe obuphezulu; ezona mveliso ziphambili zinamalungelo awodwa omenzi wechiza; esona siphumo sonyaka ophelileyo ngexesha lokubhengezwa asiyi kuba ngaphantsi kwe-50% yomthamo wemveliso waloo nyaka.
"Iimeko zomgangatho webhetri yeLithium-ion (2021)" ikwafuna ukuba iinkampani zamkele iteknoloji ephucukileyo, ukonga umbane, ukulungelelana kokusingqongileyo, ukhuseleko nozinzo, kunye neenkqubo zokuvelisa ezikrelekrele kakhulu kunye nezixhobo, kwaye zihlangabezane nezi mfuno zilandelayo: 1. Lithium-ion iinkampani ibhetri kufuneka babe Ukukwazi esweni ukufana electrode emva kokutyabeka, kunye nokuchaneka ulawulo electrode ukutyabeka ubukhulu nobude akukho ngaphantsi kwe 2μm kunye 1mm ngokulandelelanayo; kufuneka ibe neteknoloji yokumisa i-electrode, kwaye ukuchaneka kokulawula umxholo wamanzi akufanele kube ngaphantsi kwe-10ppm. 2. Iinkampani zebhetri ye-lithium-ion kufuneka zibe namandla okulawula iimeko zokusingqongileyo ezifana nobushushu, ukufuma kunye nokucoceka ngexesha lenkqubo yokutofa; kufuneka babe nokukwazi ukubona iimvavanyo zangaphakathi ze-short-circuit high-voltage (HI-POT) kwi-intanethi emva kokuhlanganisa ibhetri. 3. Amashishini ebhetri ye-Lithium-ion kufuneka abe namandla okulawula i-voltage yesiphaluka evulekileyo kunye nokuchasana kwangaphakathi kweeseli enye, kwaye ukuchaneka kokulawula akufanele kube ngaphantsi kwe-1mV kunye ne-1mΩ ngokulandelanayo; kufuneka babe nokukwazi ukujonga umsebenzi webhodi yokukhusela ipakethi yebhetri kwi-intanethi.
