Batteries are the environmental Achilles heel of electric
vehicles—unless we repair, reuse and recycle them

Electric vehicle advocates say the cars ultimately have a smaller
carbon footprint than their fossil-fueled counterparts and could
resolve our energy concerns for good. Well, fair enough, but
questions arise when we dig into the inner layers of electrical
vehicles and see how sustainable their components are. In fact,
the batteries that power electric vehicles may also be their
Achilles heel.

Batteries are the most expensive component of an electric
vehicle. If the battery pack is damaged, defective or simply old,
this can lead to the vehicle being written off prematurely. Tesla
is even producing "structural" battery packs described as having
"zero reparability".

Increasingly scarce and valuable resources, such as lithium and
water, are needed to make these batteries. Despite this, they are
often not designed for ease of repair, reuse or recycling. This
has significant environmental impacts, ranging from the mining
for materials and the water and energy used in making new
batteries and vehicles, through to the hazardous waste from
discarded batteries.

In other words, the answer to the question of "Are electric
vehicles really eco-friendly?" largely depends on how we manage
the downsides associated with their batteries. Changes in how we
design, produce, use and recycle electric car batteries are
urgently needed. These changes can ensure that, in solving the
problem of fossil fuel emissions, we also minimize other
environmental harms.

Tackle the problems before they get too big

It's important to resolve these issues now, while electric
vehicles make up a small fraction of the global vehicle fleet.
Even in world-leading Norway, only 20% of cars on the road are
electric. In Australia, fewer than 100,000 out of 20 million
registered vehicles are battery-powered.

Yet already we are wrestling with the emerging concerns about
their batteries. The performance of lithium batteries in an
electric vehicle can degrade to 70-80% of its full capacity
within six to ten years, depending on the owner's driving
routine. At that point, the battery is barely reliable as the
main energy source of the vehicle. Repeated fast charging can
degrade a battery sooner.

Globally, about 525,000 batteries will reach the end of their
useful life for powering a vehicle by 2025. That number soars to
over 1 million by 2030.

There's life after EVs for batteries

However, the total lifetime of lithium batteries is 20 years.
This means the end of a battery's usefulness in a vehicle doesn't
necessarily mean it has to be discarded. These retired batteries
can have plenty of other uses.

So how much capacity does a retired battery still have? As an
example, an energy storage made of five repurposed Chevrolet Volt
batteries can meet two hours of peak-use energy demand for five
houses. The numbers become even more appealing for Tesla Model 3
batteries, which have three times the energy capacity of the
Chevrolet Volt's.

That is a tremendous capacity still available in a retired
battery. So why not use that?

And once the battery has reached the end of its useful life, most
of the raw materials used to make it can be recovered. It is
possible to extract over 95% of the valuable metals like lithium,
nickel, cobalt and copper. The European Union already requires
electric vehicle batteries to be at least 50% recyclable by
weight, increasing to 65% by 2025.

However, the current lack of standardization of battery packs
presents a challenge for battery recycling. There are many
different physical configurations, cell types and cell
chemistries.

Reuse has a long value chain

The good news is that battery reuse is not a fictional utopia.
Carmaker Nissan is already doing it on Koshikishima, an island in
south-western Japan. Batteries are recovered from electric
vehicles, have their health assessed and then allocated to
suitable second-life applications.

These batteries can be reused in a solar farm, as an emergency
household power supply, or for an electric forklift in a
warehouse. Research shows this repurposing of batteries can get
another 10-15 years' use out of them. That's a huge leap towards
reducing their environmental impact.

So, who benefits from this scheme? Well, there's a long list.

In the first row, electric vehicles owners benefit immediately if
their used batteries can be sold for a good price.

In the longer run, the list of beneficiaries expands massively.
Households can enjoy more reliable and cheaper energy simply by
charging up their battery storage during off-peak hours for use
at peak times when electricity costs are higher. As an initiative
in Portugal showed, using repurposed electric vehicle batteries
in this way could cut energy bills by 40%.

Reusing batteries is good news for the environment. Research
suggests reducing the demand for new batteries in this way could
cut greenhouse gas emissions from making batteries by as much as
56%.

The long list of benefits of giving electric vehicle batteries a
second life, then recycling their materials, is enticing. Given
the scale of the potential economic and environmental gains,
along with the countless jobs such work can create, batteries
could be more generous in their afterlife than in their first
incarnation in electric vehicles.

This is Shortwave Radiogram in MFSK64

Please send your reception report to radiogram@verizon.net
 

Next, Shortwave Radiogram will transmit a photo of a Crimson
Rosella, a species of parrot, first in MFSK64, then in MFSK32,
and finally in MFSK16. Each image will take about the same amount
of time to transmit, but you will notice a difference in the
resolution.
