Fa'aaogāga ole sodium carboxymethyl cellulose e fai ma fa'amau i ma'a
Sodium carboxymethyl cellulose (NaCMC) o se vai-soluble cellulose derivative lea e masani ona faʻaaogaina e fai ma fusi i le gaosiga o maʻa. O maʻa o masini eletise ia e faʻaliliu ai le malosi faʻamalosi i le eletise ma faʻaaogaina i le tele o faʻaoga e pei o le faʻaogaina o masini eletise, taʻavale eletise, ma faiga faʻafouina.
O le NaCMC o se mea faʻapipiʻi lelei mo maʻa ona o ona mea e sili ona lelei e fusifusia ai, maualuga le gafatia o le vai, ma le mautu lelei i vaifofo alkaline. O nisi nei o faʻaoga a le NaCMC e fai ma fusi i maa:
- Ma'a ta'ita'i-acid: NaCMC e masani ona fa'aaogaina e fai ma mea fa'apipi'i i ma'a ta'i-acid. O ma'a ta'ita'i-acid o lo'o fa'aaogaina lautele i mea tau ta'avale, fa'apea fo'i ma faiga fa'aleoleo ma le malosi fa'afouina. O fa'aeletise i ma'a ta'ita'i-acid e faia i le ta'ita'i dioxide ma le ta'ita'i, lea e fusia fa'atasi ma se fusi. O le NaCMC o se mea fa'apipi'i lelei mo maa ta'ita'i-acid ona o le maualuga o le malosi o le fusifusia ma le mautu lelei i le electrolyte acidic.
- Ma'a u'amea u'amea u'amea: O lo'o fa'aaogaina fo'i le NaCMC e fai ma mea fa'apipi'i i ma'a hydride nickel-metal hydride. Nickel-metal hydride maa o loʻo faʻaaogaina i taʻavale eletise eletise ma masini eletise feaveaʻi. O eletise i maa nickel-metal hydride e faia i le nickel hydroxide cathode ma se anode hydride metal, lea e fusia faatasi ma se fusi. O le NaCMC o se mea fa'apipi'i lelei mo maa nickel-metal hydride ona o lona mautu lelei i vaifofo alkaline ma le malosi fa'amau.
- Lithium-ion maa: NaCMC e faʻaaogaina e fai ma fusi i nisi ituaiga o maʻa lithium-ion. O maa Lithium-ion e faʻaaogaina lautele i masini eletise feaveaʻi, taʻavale eletise, ma faiga faʻafouina malosi. O eletise i maa lithium-ion e faia i le lithium cobalt oxide cathode ma se graphite anode, lea e fusia faatasi ma se fusi. O le NaCMC o se mea faʻapipiʻi lelei mo nisi ituaiga o maʻa lithium-ion ona o le maualuga o le malosi o le fusifusia ma le mautu lelei i solvents organic.
- Ma'a Sodium-ion: O lo'o fa'aogaina fo'i le NaCMC e fai ma mea fa'apipi'i i nisi ituaiga o ma'a sodium-ion. O ma'a Sodium-ion o se suiga lelei i ma'a lithium-ion aua e tele le sodium ma taugofie nai lo le lithium. O eletise i maa sodium-ion e faia i le sodium cathode ma se graphite poʻo le carbon anode, lea e fusia faʻatasi ma se fusi. O le NaCMC o se mea fa'apipi'i lelei mo nisi ituaiga o ma'a sodium-ion ona o lona malosi fa'apipi'i maualuga ma le mautu lelei i so'o so'o.
I le faʻaopoopoga i lona faʻaogaina o se fusi i maʻa, o loʻo faʻaogaina foi le NaCMC i isi faʻaoga e pei o meaʻai, vailaʻau, ma mea tau tausiga a le tagata lava ia. E masani ona iloa e saogalemu e lala sooupu e pei o le US Food and Drug Administration (FDA) ma e manatu o se mea faʻaopoopo saogalemu ma aoga.
