Examples
Embodiment 1
[0032] with LiPF 6 It is an electrolyte lithium salt, EC / EMC is an aprotic organic solvent, and 1-perfluoropropyl phosphoric anhydride (FPACA) is used as an additive, where EC:EMC=1:2, LiPF 6 The mass fraction is 12%, and the FPACA mass fraction is 0.1% (the above ratios are all mass ratios), in a dry glove box filled with high-purity argon (H 2 O2 6, stirred evenly, transferred to a 1L fluoride bottle through a funnel, sealed with aluminum plastic film, and then added an appropriate amount of electrolyte to Li / LiNi 0.5 mn 1.5 o 4 Coin Cell and Graphite / LiNi 0.5 mn 1.5 o 4 Charge and discharge test in full battery.
Embodiment 2
[0034] with LiPF 6 It is an electrolyte lithium salt, EC / EMC is an aprotic organic solvent, and FPACA is used as an additive, where EC:EMC=1:2, LiPF 6 The mass fraction is 12%, and the FPACA mass fraction is 0.5% (the above ratios are all mass ratios), in a dry glove box filled with high-purity argon (H 2 O2 6 , stirred evenly, transferred to a 1L fluoride bottle through a funnel, sealed with aluminum plastic film, and then added an appropriate amount of electrolyte to Li / LiNi 0.5 mn 1.5 o 4 Coin Cell and Graphite / LiNi 0.5 mn 1.5 o 4 Charge and discharge test in full battery.
Embodiment 3
[0036] with LiPF 6 It is an electrolyte lithium salt, EC / EMC is an aprotic organic solvent, and FPACA is used as an additive, where EC:EMC=1:2, LiPF 6 The mass fraction is 12%, and the FPACA content is 2% (the above ratios are all mass ratios), in a dry glove box filled with high-purity argon (H 2 O2 6 , stirred evenly, transferred to a 1L fluoride bottle through a funnel, sealed with aluminum plastic film, and then added an appropriate amount of electrolyte to Li / LiNi 0.5 mn 1.5 o 4 Coin Cell and Graphite / LiNi 0.5 mn 1.5 o 4 Charge and discharge test in full battery.
