Image alt BroadBit Batteries is proud to commercially launch ProLion-001: its new, high-performance electrolyte for Li-ion batteries. This new Li-ion electrolyte overcomes the key performance limitations of current Li-ion electrolytes and enables higher temperature operation, improved safety, longer cycle-life, faster charging and higher power (particularly at low temperatures).

The proper choice of battery electrolyte is key to achieving safe and robust operation, fast-charging, long cycle life and operability in both hot and cold environments. Li-ion battery electrolytes typically employ LiPF6 salt. However, the thermal instability of LiPF6 limits battery operable temperature and cycle life and necessitates expensive battery pack cooling systems. Moreover, LiPF6 is the source of toxic (hydrogen flouride) fumes in battery fires.

BroadBit Batteries has developed a battery electrolyte which overcomes the issues associated with LiPF6 salt-based electrolytes, while simultaneously improving performance.

BroadBit’s ProLion-001 electrolyte is compatible with NMC cathodes and all standard Li-ion anodes, and has the following key performance properties:

  • Improved cycle-life (tested for graphite-NMC electrodes)
  • Higher temperature stability (75 ℃)
  • Higher initial cycle Coulombic efficiency (up to 94% for graphite anode, 91% for NMC cathode)
  • Higher low temperature conductivity in (3.2 mS/cm at -10 ℃)
  • Higher voltage / faster charging (stable at least up to 4.4 V charging voltage)
  • Lower resistance electrode-electrolyte interface / higher discharge capacity (>200 mAh/g @ 0.1 C, >175 mAh/g @ 1 C for NMC)

ProLion-001 achieves all this without sacrificing cell power or ion conductivity (7 mS/cm at 25℃).

ProLion-001 is now available for commercial testing with select partners. To learn more, contact David Brown at david.brown@broadbit.com / +358 50 344 4204.
