"Lithium-ion bhatiri indasitiri mamiriro ezvinhu (2021)" inokurudzira kutungamira makambani kudzikisa mapurojekiti ekugadzira anongowedzera huwandu hwekugadzira, kusimbisa hunyanzvi hwetekinoroji, kuvandudza mhando yechigadzirwa, uye kuderedza mitengo yekugadzira. Makambani ebhatiri eLithium-ion anofanirwa kusangana nemamiriro anotevera: muPeople's Republic of China akanyoreswa zviri pamutemo uye akagadzwa munyika, ane hunhu hwakazvimirira hwemutemo; kugadzirwa kwakazvimirira, kutengesa uye kugona kwesevhisi yezvigadzirwa zvine hukama muindasitiri yebhatiri yelithium-ion; R&D kushandiswa hakusi pasi pe3% yemari huru yebhizinesi yegore, uye makambani anokurudzirwa kuwana akazvimirira eR&D masangano padanho repurovhinzi Zvikwaniriso zvenzvimbo dzetekinoroji kana mabhizinesi epamusoro-soro; zvigadzirwa zvikuru zvine hunyanzvi hwekugadzira patent; iyo chaiyo yakabuda yegore rapfuura panguva yekuzivisa haizove iri pasi pe50% yesimba chairo rekugadzira regore rimwe chete.
"Lithium-ion bhatiri indasitiri chiyero mamiriro (2021)" inodawo kuti makambani atore tekinoroji yepamusoro, inochengetedza simba, inochengetedza zvakatipoteredza, yakachengeteka uye yakagadzikana, uye ine hungwaru hwekugadzira maitiro nemidziyo, uye kuita zvinotevera zvinodiwa: 1. Lithium-ion makambani ebhatiri anofanira kunge ane Kugona kutarisa kufanana kwe electrode mushure mekuputira, uye kutonga kurongeka kwe electrode coating ukobvu uye kureba hazvisi pasi pe2μm uye 1mm zvichiteerana; inofanirwa kunge iine tekinoroji yekuomesa electrode, uye kurongeka kwekutonga kwemvura hakufanire kunge kuri pasi pe10ppm. 2. Makambani ebhatiri yeLithium-ion anofanirwa kuve nekugona kudzora mamiriro ezvakatipoteredza senge tembiricha, hunyoro uye kuchena panguva yekubaya jekiseni; vanofanirwa kuve nekwaniso yekuona mukati mapfupi-circuit high-voltage bvunzo (HI-POT) pa-line mushure mekusangana kwebhatiri. 3. Lithium-ion bhatiri pack mabhizinesi anofanirwa kuve nekwaniso yekudzora yakavhurika yedunhu voltage uye kupikisa kwemukati kwesero rimwe chete, uye kurongeka kwekutonga hakufanirwe kunge kuri pasi pe1mV uye 1mΩ zvichiteerana; ivo vanofanirwa kuve nekwaniso yekutarisa bhatiri pack kuchengetedza bhodhi basa online.
Panyaya yekushanda kwechigadzirwa, iyo "Lithium-ion Battery Indasitiri Mamiriro ezvinhu (2021 Edition)" yakaita zvinotevera zvinodiwa:
(1) Mabhatiri nemabhatiri mapaketi
1. Mutengi bhatiri simba density ≥230Wh/kg, bhatiri pack simba density ≥180Wh/kg, polymer bhatiri vhoriyamu simba density ≥500Wh/L. Hupenyu hwekutenderera ndeye ≥500 nguva uye chiyero chekuchengetedza simba ≥80%.
