E-Technology today stores 5.66 times more energy compared to current best batteries.

BEE 6, the last prototype, demonstrated (in an operational environment) its energy density at 789Wh/kg.


For comparison purposes:

  1. the IEA targets that batteries may reach an energy density of the 780Wh/kg in 2050.

  1. Elon Musk(@elonmusk – Aug, 25, 2020) predicts 400 Wh/kg *with* high cycle life, produced in volume (not just a lab) is not far. Probably 3 to 4 years,”

Musk said last year that for electric flight to work, the energy density of batteries needed to improve to over 400 Wh/kg, a threshold which may be achieved in five years. (Reuters, Aug, 25, 2020)

Researchers have said the energy density of Panasonic’s 6752.T “2170” batteries used in Tesla’s Model 3 is around 260 Wh/kg, meaning a 50% jump from the current energy density which is key to achieving a longer driving range.

The probability that E-Technology (mobile or stationary) would drive the energy transformation across the world is very real. It is the missing link, the catalyst that drastically improves efficiency of the management  of solar and wind energy production, and eliminates peak and off-peak management, allowing for current grid capabilities to cover growth over many years to come without CAPEX.

  • EVs could have the same autonomy, level of comfort and price as current ICE vehicles and long-distance. Electrical propulsion of aircraft could be at reach.
  • Domestic / Home stationary units could ensure grid-independent power availability over long periods.
  • Grid mass storage units (incl. home units) will massively reduce peak and off-peak management, and
  • E-Technology could fit 3x the Tesla Hornsdale (AU) capability in the back of a Semi (360 MWh).
