1 Te whakahaere i te pākahiko rokiroki maroke kei roto te pākahiko mēkuri (pēhiko rokiroki maroke) e pā ana ki te pākahiko mercury iti, tikanga nui mo te maimoatanga, whakakoi. Mo te pākahiko mēkuri nui (pērā i te pūhiko waro-konutea me te pūhiko konutea konutea konupora), he tikanga maku me te tikanga waiariki. Ko te tikanga rewharewha makuku me te tikanga rewharewha tika.

Kua wehea te Tikanga Ahi ki te pehanga pehanga noa me te ture whakarewa korehau. I tenei wa, Switzerland, Japan, Sweden, US, etc. 2 Ko te maimoatanga o te pākahiko tiima-waikawa maimoatanga i te timatanga o te 1990s, he mea nui te tukanga whakaora pākahiko mata-waikawa i whakamahia i te timatanga o nga tau 1990 ki te whakawehenga o te pouaka, te whakarōpūtanga (te paura mata, te paru mata, te kongakonga mata iti, te para mata, te whakahou, me era atu.

I nga tau tata nei, kua whakawhanakehia e toku whenua tetahi waahi hou mo te whakawhanaketanga o te hangarau tukurua pākahiko ururua, a he nui te pai o te whakaora me te parahanga iti o tenei hangarau. 3 Te maimoatanga o nga pākahiko nickel-containing me te nickel-cadmium-containing battery-containing pākahiko, i tenei wa e rua nga momo tikanga maroke me te makuku. He mea nui te tukanga maroke ki te whakamahi i te cadmium me tona pehanga kohu waikura me te wehenga nickel.

Ka whakamahia e te tukanga maku nga rereketanga o te cadmium sulfide me te nickel sulfide, te whakahaere i etahi tikanga, te wehe i te nickel, te cadmium. 4 Ko te tukanga maimoatanga pākahiko Lithium o te pākahiko lithium ka tahuna tuatahi ki te tango i te pākahiko ki te tango i nga mea pararopi, katahi ka tirotirohia ki te rino me te parahi, ka wera te toenga o te paura wera me te rewa i roto i te waikawa, ka taea te whakaaro ki te waikura cobalt hei whakarewa pararopi. Pigment, rauemi hanga mo te peita.
