Lithium Australia takes a major leap towards producing safe Li battery

Summary

  • Lithium Australia's wholly-owned subsidiary, VSPC, has produced LMFP cathode powders.
  • LMFP batteries have high energy density with an enhanced safety factor, and the cost factor also gets reduced.
  • VSPC also sees LMFP potential in transportation applications.

Lithium Australia NL (ASX: LIT) updated that its 100%-owned subsidiary VSPC Ltd has successfully produced LMFP cathode powders that exhibit better performance.  

VSPC has taken significant strides towards improving energy density of LFP LIB cells by adjusting its proprietary manufacturing processes through adding manganese into the cathode active material during production.

LMFP batteries' multiple advantages 

The LMFP batteries made with these materials have high energy density due to high voltage as compared to regular LFP cells. Furthermore, these battery cells are low-cost and have enhanced safety factor.

  • Globally, major LFP cell manufacturers are trying to increase the energy density by incorporating manganese in the cathode powder. When compared with LFP cells, LMFP cells have 25% higher energy density due to higher voltage.
  • LFP and LMFP cells have higher thermal stability and longer service life when compared to nickel-cobalt manganese ('NCM') and nickel cobalt aluminium ('NCA'), which are commonly used in EVs. The fundamental physical properties of phosphates which is olivine-like crystal structures, give superior characteristics to LFP and LMFP batteries. On the other hand, both NCM and NCA have a spinel (oxide) structure defined by comparatively low-strength chemical bonds. 
  • Ability to produce high-performance LIBs without the need for nickel or cobalt brings in many advantages. The safety characteristic is high in LMFP batteries. The cost of raw material is lower due to the use of common bulk commodities like manganese, iron and phosphorus, which also gives access to a much more reliable supply chain.
  • Another significant benefit of LMFP is that its commercialisation for LIBs production will eliminate the need for raw materials from areas where there is human rights abuse going on like the use of child labour. Also, batteries produced from industrial waste and used batteries give more sustainability and reduce the supply chain risk.

VSPC updates

  • The company  has also set its eyes on developing a rapid-charge battery for transportation applications. Thanks to the positive results obtained from testing LMFP cells, VSPC can utilise its patented process to manufacture LMFP for transportation applications.
  • Also, due to these cells' higher energy density, it is expected to mitigate the 'range of anxiety' related to standard LFP built for EVs. 
  • VSPC is conducting active programs to reduce costs even further by the evaluation of industrial waste materials as feed and production of cathode-material from used LIBs.

Stock performance: On 3 December 2020, at AEDT 12:55 PM, LIT was trading at AUD 0.060, up by 5.263% with a market capitalisation of AUD 45.15M.
