Lithium-ion (Li-ion) Batteries

NB: Lithium-ion (Li-ion) technology has been superseded by the safer Lithium-iron Phosphate (LiFePo4) technology.   This video explains the issues associated with Recycling Lithium battery’s. 

So what should you know about Lithium Batteries ?

Simply put, it largely to do with the battery cost per *kWh;

  1. 15kWh Graphene Super Capacitor (SC) Modules cost approx. $14'950 ÷ 15 =$995 per kWh.
  2. 10.24 kWh Lithium iron phosphate (LiFePo4) battery cost approx. $5'050 ÷ 10.24 =$494 per kWh.
  3. 12 kWh Nickel iron (NiFe) batteries (Edison battery) cost approx. $6'720 ÷ 12 =$560 per kWh.
  4. 3.0 kWh Portable VigorBox Lithium-ion battery cost approx. $1'950 ÷ 3 =$650 per kWh.
  5. 13.5 kWh Tesla Lithium-ion battery cost approx. $8'800 ÷ 13.5 =$650 per kWh.
  6. 10 kWh RedFlow Bromide battery cost approx. $10'000 ÷ 10 =$1'000 per kWh (Australian company).

Clearly leaving LiFePO4 & NiFe batteries well ahead of the rest in price, where NiFe are reported as new after 30 years!

Batteries/Energy storage is predominantly designed for use between Sunset & Sunrise, or in the event of a blackout, by storing energy generated from Solar, and is ideally suited for storing energy from Aqua, Wind or Generators.

You can load shift (draw electricity from the state power grid to charge the battery), usually this is done slowly at night when rates charges are low, to store for later use.

However, what is not widely advertised is the facts that, "the investment cost for ALL small to large scale micro power grids", are able to be self funded based on energy savings alone, from 4~6+ years when using DAT Solar Arrays !
