While the initial performance in terms of energy density (Wh · kg ^–1 ) of the newborn Li-ion technology seemed, in 1991, interesting (around 80 Wh · kg ^–1 ) compared to competing Ni-Cd (50 Wh · kg ^–1 ) or Ni-MH (75 Wh · kg ^–1 ), However, they are not decisive enough for them to be used in areas other than high value-added on-board electronics (consumer electronics or specific applications such as the military, etc.): military, etc.). In any case, at the time, their manufacturing cost was far too high (around $4,000-5,000 · kWh ^–1 ...
