  • When a new battery technology is introduced on the market, it does not

« kill » the other battery technologies.

  • Because it comes with new benefits, but also with some weakness.
  • The best battery technology does not exist. For each particular

application, we have to identify the more relevant battery technology.

  • Today, the oldest battery technology (Lead-acid) is the 1st one in term of

sales.

Lead-acid Li-ion Ni-MH

pros

Price is much lower vs

  • ther battery

technologies. High energy density.

  • 40°C to +85°C.

2000 to 5000 cycles at 100% DOD. Non-flammable.

cons

Discharge at low T°C. Life duration reduced significantly above 45°C. T°C > 60°C. Charge below 0°C. flammable Purchasing price (but TCO is attractive).

Used for …

Applications not so much demanding (performances). Mobile applications. Indoor. Outdoor applications. Strong and deep cycling. Demanding applications.

  • Ni-MH is not well-known because it is used in professional applications:

 Lead-acid is known because of the car battery  Li-ion is known because of the smart phone and portable computer battery

  • But Ni-MH is known and appreciated for its robustness by battery experts.

 Used since 20 years inside the Toyota Prius  Used in the Middle-East for solar autonomous devices  More and more used in aviation (safety)
