What if we could recycle the energy remaining in discarded
batteries? Scientists now know how

by Cactus Communications
August 11, 2022

Alkaline and zinc-carbon batteries are common in many
self-powered devices. However, once a battery is discharged, it
is no longer usable and is discarded. According to estimates,
nearly 15 billion batteries are produced and sold worldwide
annually. Most of these end up in landfills and some are salvaged
for valuable metals. However, although these batteries are not
usable, there is usually a small amount of energy left in them.
In fact, about half of them contain as much as 50% energy.

Recently, a group of researchers from Taiwan investigated the
feasibility of recovering this energy from single-use (or
primary) discarded batteries. Led by Professor Chien-Hsing Lee
from NCKU, Taiwan, the group focused its research efforts on this
front to promote a circular economy for discarded batteries.

The researchers, in their study, proposed a new method called
"self-adaptive pulse discharge" (SAPD) that can be used to
determine the optimal values of two key parameters—pulse
frequency and duty cycle—that determine the discharge current
from the discarded batteries. A high discharge current, simply
put, amounts to a high amount of recovered energy.

"Draining small remaining energy from household batteries is a
starting point for waste reduction, and the proposed energy
recovery method serves as an effective tool to reutilize a large
number of discarded primary batteries," says Prof. Lee,
explaining his motivation behind the study, which was published
in IEEE Transactions on Industrial Electronics.

Additionally, the researchers built a hardware prototype for
their proposed approach that was used to recover the remaining
capacity of a battery bank capable of holding at least 6 and at
most 10 batteries of different brands. They managed to recover
between 798–1455 J of energy with a recovery efficiency between
33%– 46%.

For a discarded primary cell, the researchers found that the
short-circuit discharge (SCD) method had the highest discharge
rate at the beginning of the discharge cycle. However, the SAPD
method showed a higher discharge rate at the end of the discharge
cycle. By using the SCD and SAPD methods, the energy recovered
were 32% and 50%, respectively. However, upon combining these
methods, 54% of energy was recovered.

To further validate the feasibility of the proposed method, a few
discarded AA and AAA batteries were chosen for energy recovery.
The team could successfully recover 35%–41% of the energy from
discarded batteries. "While there seems to be no advantage in
draining a small amount of energy from a single discarded
battery, the recovered energy significantly increases if a large
number of waste batteries are exploited," says Prof. Lee.

The researchers suggest that there could be a direct link between
the recovery efficiency and the remaining capacity of discarded
batteries. As for the future implications of their work, Prof.
Lee speculates that "the model and the prototype developed can be
applied to battery types other than AA and AAA. In addition to
different types of single-use batteries, rechargeable batteries,
such as lithium-ion batteries, can also be examined to provide
more information about the variability among different
batteries."

From Futurity.org:

Being a family dog can be a lonely, stressful job

August 11, 2022
Posted by Michael Skov Jensen, University of Copenhagen

Dogs that live with a family have it better than dogs that
roam free when it comes to safety, nutritious food, and vet
care. But it's a different story with regards to their
mental health.

You would need to travel far from Denmark to meet a dog that
roams the village streets freely, without belonging to any one
family, one that may seem a bit shabby and underweight. One could
easily believe that "village dogs" would be better off in a safe
and stable environment alongside a family in suburban Denmark.
But things aren't quite that simple.

The life of a typical Danish "family dog" comes with a price.
Dogs have evolved to run freely among other dogs and humans,
according to researchers at the University of Copenhagen's
veterinary and animal sciences department and food and resource
economics department. In a new study, the researchers compare the
welfare of the modern family dog and the free-roaming village
dog.

The shared history of dogs and humans extends 10,000 years, to
the time when dogs first became domesticated as pets. But over
the past two centuries, the typical dog's life has changed
dramatically. Dogs have gradually evolved from living freely on
farms, where there were always people around and other dogs
nearby, to moving into small urban homes, as pets which were
acquired to satisfy their owners, with confinement and loneliness
built into the equation.

In today's Denmark, where dogs are not allowed to roam freely in
public spaces, the free-roaming village dog no longer exists.

To compare the typical Danish family dog's welfare with something
more "original," the researchers looked at studies of village
dogs in Mexico. Along with many other less economically developed
countries, Mexico is home to the majority of dogs in the world
today. Many of these dogs live a life closer to their species'
primal nature.

"Until about 50 years ago, there were still dogs in Denmark that
lived more or less naturally. Since then, we have yanked them
from their natural niche and created the modern family dog, which
presents a few challenges for dogs," explains coauthor Peter
Sandøe, professor of bioethics.

Loneliness and anxiety

For many families, 21st century work and institutional life means
that people are away from home for a large portion of their day.
During that time, dogs are left to their own devices. It is a
life that doesn't harmonize with the social needs of dogs, which
need to spend time in the company of humans and other dogs.

"Dogs that are often left alone at home or that haven't gotten
progressively used to being alone can be affected by separation
anxiety or other separation-related issues like boredom and
frustration. At times, dogs vent their anxiety or frustration by
gnawing on furniture, peeing on floors, or destroying homes.
These are problems that prompt some owners to euthanize or give
their dogs away. While most dogs suffer in a less destructive
way, they don't necessarily have fewer problems," Meyer says.

In sharp contrast to the their largely lonely lives, we have
extremely high expectations for how dogs should behave when with
us. Preferably, a dog should be able to interact with other dogs,
allow itself to be petted by strangers, and in general, be able
to satisfy its owners—which is not always realistic.

Unlike the village dog, which often roams freely with other dogs
in small packs, and chooses with whom and when it wants to be
social, the family dog does not experience the same natural form
of socialization.

"Most dog owners have heard that socialization is
important—puppies need to learn to be with other dogs, etc.
Therefore, people seek out places with many other dogs, expecting
for their dog to be social on command. The problem is that this
is not very natural for a dog, which can risk having a bad
experience that persists and can contribute to developing
problematic behavior," Sandøe says.

"Socialization is about giving a puppy positive experiences with
other dogs and humans. If your puppy's boundaries are crossed or
they don't have the opportunity to pull away, it won't have a
good experience and could lead to problems with aggressive
behavior. In my work, I've seen examples of owners who walk their
dogs at night to avoid unpleasant encounters with other dogs or
people. This type of problem can easily be caused by negative
social experiences from earlier in a dog's life," Meyer adds.

Give your dog a break

To make life easier for your dog, researchers suggest that it is
very much about accepting that our dogs cannot always live up to
everything we expect of them. Dogs are social and not designed to
be home alone, all day long. This needs to be considered before
getting a dog.

"You need to consider whether your life can satisfy a dog's
social needs. Most dogs can learn to be alone for part of the
day, but I think we can go further to meet the social needs of
dogs compared to what we do today. For example, there is a rule
in Sweden that dogs can only be left alone at home for six hours
at a time," says Sandøe.

Finally, we need to learn to take our dogs' differences into
account.

"Research demonstrates that dogs have very different
personalities, even within the same breed. It is important to not
paint all dogs with the same brush, and instead, learn to
understand the dog that we live with. This is particularly true
in social contexts, where we need to try to avoid forcing a dog
into something that it doesn't want to do. A dog owner's most
important job is to help their dog to live a good life within the
limitations that come from growing up as a family pet in
Denmark," Meyer says.
