lithium ion battery recycling

Recycling costs to be added to purchase cost of renewable energy storage batteries – new Australian legislation coming.

When looking at the cost of a battery system, either domestically or commercially or as an electric vehicle it is important to look at “total cost of ownership” of TCO.

This means not only considering the initial cost of the battery but;
the costs of all the components of a battery system that are needed for an installation including inverters, MPPT’s, communications etc.,
the length of time to install a complete system,
The running costs associated with the system, including maintenance,
The expected lifetime of the battery installation
End of life disposal costs.

Up until now, in Australia, end of life costs for batteries have not been considered. This is becoming increasingly problematic for lithium-ion batteries. Multiple lithium-ion chemistries need to have multiple processes for dismantling, recycling and recovery processing, meaning there is not a standard recycling process that can be put in place.

In fact, lithium phosphate batteries (LFP), which are a safer lithium-ion battery technology, due to it being less likely to catch fire, actually have less value when recycling, meaning LFP batteries have a higher upfront cost but will also have a higher recycling cost, although they are inherently safer than Li-NMC batteries.

Battery Recycling

One of the things that you should consider when putting battery storage on your home is whether or not the battery will be recyclable at the end of its life.
Recycling batteries at the end of their life has a number of benefits:

  • It enables the recovery and reuse of materials including lead, iron, plastics, aluminium, copper, lithium, cobalt and electrolyte
  • It diverts toxic and hazardous materials from landfill
  • It ensures that batteries are managed safely
  • There may be a financial return (depending on the battery type).

Often, one of the reasons that people put solar panels on their house and put in battery storage to collect the excess usage is to protect the environment and reduce the need for coal powered power stations. This can be counterproductive if you choose a battery that is made from toxic materials or has components that can’t be recycled at end of life of the battery.

When batteries go to landfill toxic substances can cause damage to the waste stream, waterways, humans and the general environment. This can be nickel, cadmium, lead or lithium ion.

Recycling of energy storage batteries is a current weakness in the industry for many battery technologies.
