Ol i ken yusim ol 'zeolite molecular sieves' long rausim wara long ol 'electrolytes' long rot bilong 'physical adsorption', na abrusim ol hevi bilong wara na long dispela rot ol i ken mekim wok na sefti bilong 'lithium battery' i kamap gutpela moa, we i bin pulim bikpela luksave i no long taim i go pinis.
Ol samting insait long ol komon litiam elektrolait
Ol 'organic solvents' em ol bikpela samting insait long 'electrolyte', na ol i save kisim samting olsem 80%~90%. Ol dispela solvent em 'ethylene carbonate' (EC), 'dimethyl carbonate' (DMC), 'propylene carbonate' (PC), 'diethyl carbonate' (DEC), 'ethyl methyl carbonate' (EMC), na ol narapela.
Sol bilong 'lithium' em i narapela samting insait long 'electrolyte' na em i as bilong 'lithium'. Ol dispela litiam sol i gat litiam heksafluorofosfet (LiPF6), lithium bis(fluorosulfonyl)imide (LiFSI), lithium tetrafluoroborate (LiBF4), lithium perchlorate (LiClO4), na ol narapela.
Ol 'additives' i save kisim samting olsem 5% bilong 'electrolyte'. Ol dispela aditiv i gat ol samting bilong wokim piksa, ol samting bilong pasim paia, ol samting bilong strongim paia, na ol narapela samting. Olsem, ol samting bilong wokim piksa olsem vinyl carbonate (VC), fluorinated vinyl carbonate (FEC).
Long olgeta, wok bilong 'lithium electrolyte' i dipen long wok bung bilong ol 'solvent', 'lithium salt' na ol narapela samting. Olsem, bung bilong EC/DMC miks solvent na LiPF6inap long balensim tupela samting, 'ionic conductivity' na 'stability'.
Ol hevi bilong wara i stap insait long ol 'electrolytes'
Ol dispela samting i save pilim tru wok bilong ol 'electrochemical', wara na ol pipia inap long bagarapim tru wok na kwaliti bilong ol 'lithium battery'. Eksampel em:
Wara inap long wok wantaim ol sol bilong 'lithium' insait long 'electrolyte' na kamapim ol samting nogut olsem 'hydrofluoric acid' (HF) na 'lithium fluoride' (LiF), we inap long bagarapim straksa bilong bateri, kamapim lik o sot seket, na daunim strong bilong bateri.
Ol 'solid electrolyte interface' (SEI) film we i kamap long ol 'film-'forming additives inap long bagarap long wara, na i no gat strong na yunifomiti bilong en, na dispela i save mekim 'internal resistance' bilong bateri i go antap na 'discharge capacity' i go daun.
Taim ol i sasim na rausim wara, wara inap long bagarap na kamapim ol ges (olsem CO2 na H2), we i save mekim presa insait long bateri i go antap. Dispela inap long mekim bateri i kamap bikpela, wara i kapsait, na smok, paia, na pairap, na dispela inap long kamapim hevi long sefti.
Ol hevi bilong wara we ol i kolim long 'solvent treating' i stap tu insait long 'electrolyte'. Long tok sot, wara i stap i save afektim 'electrolyte conductivity', 'electrolyte interface stability', na 'battery cycle life' na sefti, em i wanpela bikpela samting bilong bosim wok bilong kamapim na yusim ol 'lithium' bateri.
Ol Molekiul Sif Bilong Rausim Elektrolait
Ol wok bilong ol 'molecular sieve' insait long ol 'electrolytes' i save senis bihainim ol wok bilong ol, olsem 'solvent drying', 'electrolyte dehydration' na 'deacidification', 'electrolyte regeneration', na strongim wok bilong 'electrochemical'.
Type 5A Zeolite Molecular Sieve em i nambawan samting bilong rausim wara long 'electrolyte', na em inap long rausim wara long 'electrolyte', na stopim ol 'internal resistance' na ol 'electrochemical reactions' i go antap, na dispela i mekim wok na sefti bilong 'lithium battery' i kamap gutpela moa.
Ol i ken putim ol 'type 3A', 4A, 13X, 'type', 'lithium type', na 'composite zeolite molecular sieves' long ol 'lithium electrolytes'. Long rot bilong yusim strongpela 'adsorption', 'ion sieving property' na 'structural stability' bilong ol, long mekim ol 'electrolytes' i kamap gutpela, i stap gut na i wok long ron gut.
