Lithium battery principle

The true core of the Nyami technology is the Lithium Iron Phosphate batteries and its optimisation on a boat. Moving from the traditional Diesel to Electricity propulsion may seem like a big step but an obvious one when exposed to the advantages. The Nyami’s are equipped with a specific Lithium battery type of the latest generation called “Lithium Iron Phosphate” (LiFePO4) due to its unique qualifications…

Different types of Lithium ?

  • Since decades lithium batteries have been widely used in power tools, laptops, electrical bicycles, mobile phones, pacemakers, etc.
  • There have been different types on lithium batteries, ie based on Cobalt, Manganese and Nickel. The Lithium iron Phosphate (LiFePO4) has been developed in Texas in 1996 and has since then outperformed the other lithium type batteries for obvious reasons :
    • inexpensive,  nontoxic, environmentally benign, no risk of overheating or outgassing, no risk of explosion during charging, higher energy storage capacity, faster recharging, 5 times longer life cycle than other Li batteries (minimizing replacements), less charge monitoring required, stable even at extreme temperatures, etc.
    • The phosphorus, iron and Lithium itself are abundantly available on earth. 
    • The positive comparison of Iron Phosphate to other lithium batteries have attracted the many end user manufacturers who have successfully implemented in vehicles, buses during Chinese Olymic games with 300km range, nuclear submarines, electrical motorcycles (fastest in the world)
  • To be able to respond to this growing demand the main LiFePO4 providers have committed to enhance production capacity (eg. China can now produce 20 million of these batteries per annum.  They are continuously exploring to further reduce size and weight and at same time increasing energy storage performance.
  • The LiFePO4 batteries of the last generation are being used in the Nyami range since most powerful, reliable and economical of all lithium batteries (see graph)
