Tetra-n-butylammonium bromide (TBAB) ke ntho e bakang ho ruruha ha letlalo.letsoai la ammonium la quaternarye kopantsoe ka lits'ebetso tse koahelang masimo a mangata:
1. Ho kopanya lintho tse phelang
TBABhangata e sebelisoa e lesethothetsi sa phetiso ea mohatoho kgothaletsa phetiso le phetoho ya di-reactant ditsamaisong tsa karabelo ya mekhahlelo e mmedi (jwalo ka mekhahlelo ya metsi a tlhaho), jwalo ka dikarabelong tsa nukleophilic substitution, ho lokiswa ha halogenated hydrocarbon, etherification, le dikarabelo tsa esterification, tse ka eketsang chai le ho kgutsufatsa nako ya karabelo.

2. K'hemistri ea motlakase
E sebelisoa lefapheng la tlhahiso ea libeteri, e le tlatsetso ea electrolyte, e ka ntlafatsa ts'ebetso ea lik'hemik'hale tsa motlakase, haholo-holo lipatlisisong tsa libeteri tsa lithium-ion, e bonts'a lits'ebetso tse ka bang teng.
3. Tlhahiso ea meriana
Matla a eona a ho bolaea libaktheria a e etsa hore e be thepa ea bohlokoa bakeng sa ho lokisa meriana e loantšang libaktheria, ha ka nako e ts'oanang e thusa ho kopanya meriana e kang ho thehoa ha naetrojene ea khabone le oksijene ea khabone.
4. Tšireletso ea tikoloho
E sebelisoa maemong a kalafo ea metsi ka phello ea ho lokolla butle-butle ha li-ion tsa tšepe e boima, bakeng sa ho tlosa kapa ho khutlisa litšila tsa tšepe e boima metsing.
5. Tlhahiso ea lik'hemik'hale
E sebelisoa lefapheng la lik'hemik'hale tse ntle bakeng sa ho kopanya lidae, monko o monate le thepa ea polymer, 'me e nka karolo ho alkylation, acylation le liketso tse ling.
