Kedu ihe bụ isi nka na ụzụ na ntinye nke batrị lithium-ion na ọnọdụ nchekwa nchekwa ike?

N'afọ 2007, ewepụtara "iwu njikwa ịnweta ụgbọ ala ọhụrụ" iji nye ntụzịaka amụma nrụpụta ụgbọ ala ike ọhụrụ nke China.N'afọ 2012, etinyere atụmatụ mmepe ụlọ ọrụ mmepụta ihe nke ike ọkụ na ume ọhụrụ (2012-2020) wee bụrụ mmalite nke mmepe ụgbọ ala China ọhụrụ.Na 2015, a tọhapụrụ "Ọrịa na amụma nkwado ego maka nkwalite na ngwa nke ụgbọ ala ike ọhụrụ na 2016-2020", nke meghere mmalite nke mmepe mgbawa nke ụgbọ ala ike ọhụrụ nke China.
