Synergistic additives for high volume lithium ion batteries

A battery cell comprising:

• a cathode comprising a cathode active material disposed on a cathode current collector;
• an anode comprising an anode active material disposed on an anode current collector, the anode oriented towards the cathode such that the anode active material faces the cathode active material;
• a separator disposed between the cathode active material and the anode active material;
• and
• an electrolyte fluid comprising 0.6-0.8 wt % lithium difluoro(oxalato)borate (LiDFOB), 3.0-4.0 wt % butane sultone (BS), 0.2 wt % prop-1-ene-1,3-sultone (PES) 0.4-0.6 wt % methylene methanedisulfonate (MMDS), 0.1-0.3 wt % tris(trimethylsilyl)borate (TMSB), 3.5-4.5 wt % fluoroethylene carbonate (FEC), 1.5-2.5 wt % succinonitrile (SN), and 2.5-3.5 wt % 1,3,6-hexanetricarbonitrile (HTCN), LiPF6, ethylene carbonate (EC), propylene carbonate (PC), propyl propionate (PP), and ethyl propionate (EP).
