Lithium-ion Batteries from Drones Might Find Second Lives in Less ‘Stressful’ Devices - Technology Org

Taking flight can be stressful — especially for a lithium-ion battery that powers a drone. Too much strain on these cells causes damage and shortens a device’s lifespan.

Research in ACS Energy Letters shows the potential to improve batteries in aerial electric vehicles that take off and land vertically. The team developed a new electrolyte to address these challenges and said the “stressed out” batteries could also have second lives in less strenuous applications.

Lithium-ion batteries (LiBs) have exploded in popularity thanks to their ability to pack a large amount of power in a relatively small, light package. But they aren’t perfect, especially when a lot of that power needs to be drawn from the battery cell quickly.

For example, drones put a high strain on their batteries during takeoff. While hobby drones traditionally use lithium-ion polymer batteries instead of LiBs, the latter’s high energy density is better suited for heavier-duty drones, such as those that deliver cargo to remote locations. To better understand how high-strain events like liftoff can affect LiB stability, Ilias Belharouak, Marm Dixit and colleagues “stressed out” a set of LiBs and investigated how their performance changed.

The researchers manufactured a set of LiB cells containing a specially designed, fast-charging and discharging electrolyte. Then, they drained 15 times the battery’s optimal capacity, the total amount of energy it could store, for 45 seconds. This process simulated the rapid, high-power draw, also known as a discharge, needed during vertical takeoff.

After the initial discharge pulse, the cells were further drained at a more normal discharge rate and then recharged. The team found that none of the tested cells lasted more than 100 cycles under these high-stress conditions, with most starting to show decreased performance around 85 cycles.

After being “stressed,” the researchers subjected the LiB cells to a more normal, lower rate power draw. In this experiment, they observed that the cells partially retained their capacities under low-rate conditions, but failed quickly when put under rapid current drain conditions again.

These results indicate that the LiBs typically used in drones might not have the characteristics necessary for long-term, high-stress usages, but they could be retired and meet more typical power demands in other applications, such as battery back-ups for power supplies and energy-grid storage. The researchers say that more work is needed to develop alternative battery technologies that are better suited for vertical takeoff and other high-power-demand applications.

When I go to the big alternative energy conferences, people ask me: what’s the most recyclable battery out there? Is it lithium-ion? Lithium-polymer? Lithium-iron-phosphate? No, friends: it’s Home Depot.

Let me explain. Stealing batteries from Home Depot is a renewable source of energy. Wow, I guess that was actually pretty simple. Allow me to expand further: the definition of renewable is that it comes back after it’s gone, right? When you fill the false lining on your jacket with flashlight D-cells, or just stuff a bunch of Evereadys down the back of your pants and constipated-penguin-walk your way off of the show floor while pretending to yell at “your wife” on “your smartphone,” those batteries will be back on the shelves the very next day, like it never even happened.

Unlike solar, too, this energy source is available all the time. In fact, it’s quite a bit easier to harvest this power at night, because the parking-lot security guard has to take his break around then.

Sure, it’s not a perfect solution. Sometimes they move them around, or they put a camera near the batteries. We’re going to need to develop new strategies to extract this energy, and it will take cooperation from everyone in society (for instance, a big guy who can stand around the paint aisle and block the loss-prevention lady.)

Overall, we need to use less energy, because I am getting tired of driving to the store every day just because I had to use an entire shipping crate full of double-A batteries to boost my car. I’m doing my part, by only using solar calculators to compute my profits from selling the excess batteries on Kijiji under the name of a local tough-on-crime politician.

Lithium-ion batteries have ruled for decades. Now they have a challenger. (Washington Post)

Excerpt from this story from the Washington Post:

After decades of lithium-ion batteries dominating the market, a new option has emerged: batteries made with sodium ions.

Scientists have been researching alternatives to lithium for years. Much of the world relies on this kind of battery, but the mining and processing of its materials can be harmful to workers, local communities and the environment.

Sodium has recently emerged as one of the more promising options, and experts say the material could be a cheaper and more environmentally friendly alternative to lithium.

In the past few years, sodium-ion battery production has increased in the United States. Last month, sodium-ion battery manufacturer Natron Energy announced it would open a “gigafactory” in North Carolina that would produce 24 gigawatt hours of batteries annually, enough energy to charge 24,000 electric vehicles.

But sodium-ion batteries are still early in their development compared with lithium-ion, and they have yet to hit the market on a massive scale.

“It’s unlikely sodium-ion could displace lithium-ion anytime soon,” said Keith Beers, polymer science and materials chemistry principal engineer at technical consultancy firm Exponent.

Here’s what to know about these batteries.

How sodium-ion batteries work

There are many types of sodium-ion batteries, but the ones that will be manufactured in North Carolina are produced in the same way as lithium-ion batteries, just with different ingredients. Instead of using expensive materials like lithium, nickel and cobalt, these will bemade of sodium, iron and manganese.

In a battery, ions move between electrodes during a charging and discharging process to generate electricity, explains Alvaro Acosta, a senior director at the solar developer Lightsource bp. In a sodium-ion battery, sodium ions carry the charge, and the negative electrode is made up of common materials like iron, carbon and nitrogen. Natron’s batteries use iron and manganese for their negative electrodes.

The biggest limitation of sodium-ion batteries is their weight. Sodium weighs nearly three times as much as lithium, and it cannot store the same amount of energy. As a result, sodium-ion batteries tend to be larger.

Jens Peters, an economics professor at the University of Alcalá in Madrid, said the energy density could be improved over time in sodium-ion batteries. But, he added, “what we found out so far in our assessments is that it is not a game changer.”

Sodium-ion batteries are touted to be the environmentally friendly alternative to their lithium-ion counterparts, thanks to their raw materials. Sodium, iron and manganese are all abundant elements on the planet, so they require less energy to extract and cost less.

“Everyone knows that lithium-ion batteries are the pulse of mobile phones, transportation,” said Yang-Kook Sun, professor of energy engineering at Hanyang University in Seoul. “The issue over lithium-ion batteries is that they use highly expensive materials like lithium, nickel and cobalt.”

Technology transforms plastic waste bottles into polymers for lithium-ion batteries

A team of A*STAR scientists has successfully upcycled waste polyethylene terephthalate (PET) plastic into polymer electrolytes, which are key components for safer lithium-ion batteries (LiBs). The study is the first known report of a working lithium-ion battery assembled using polymers upcycled from PET plastics, which are used to make plastic bottles.

The study was published in Journal of Materials Chemistry A in November 2022.

Plastic waste is a mounting problem in the world today, and it is set to grow bigger with the rising demand for plastics. 460 million tons of plastics were produced globally in 2019, but only 9% are recycled, with the remainder either being incinerated or disposed in landfills and the environment.

Plastic waste is conventionally recycled through mechanical and chemical processes, which have their drawbacks. For mechanical recycling, only a small proportion of recycled PET can eventually be used, as their physical properties degrade with each round of recycling due to polymer chain cleavage. Chemical recycling involves high energy usage, requires purified monomers and can be more costly compared to using virgin polymers.

"Hey, the laptop feels weird."

So, Sander's lid isn't closing flush. On closer inspection, the touchpad sure is popping up out of the keyboard by about the same amount as that gap you see in the above picture, so roughly 1/8".

"Ah, fuck." I think to myself. "That's probably a spicy pillow."

So, I flip Sander over and break out my handy-dandy T5 Torx bit to take the bottom of the case off. I ease my way in by working at all of the screws at once. I am careful. I am cautious...

... And I jump 3 feet out of my skin when the plate suddenly releases with a resounding CRACK:

That 1/4" gap you see there? That's not the lid. That's the bottom plate of the laptop, pushed up by the swollen chunk of chemical oh-no underneath it now that there are no screws to keep the delinquent battery subdued. Normally there are sets of clips along the inner edge of the chassis that hold the plate on, but they were no match for the Spicy Pillow.

There he is! Sander Cohen's undoing in all its glory. If you've ever wondered what a 50Wh 3-cell lithium-polymer battery looks like once it's going spicy, now you've seen it! :D

A few hours later and he's now recovering from surgery and doing quite well, though he will forever be tethered to the wall AC now that he's got no cell in there. I'm glad, because I'd just finished wiping the machine clean and setting him up for BabyCat to use for her schoolwork and some games. @_@; Her phone recently shattered (wasn't her fault either, the poor thing) and this was a way of cheering her up, and it almost went so horribly wrong.

E-VOlution: a poll-based interactive fiction

part 1 here!

A helpful little notion in the back of your head says Activate combat protocol?

Sure. Okay. Sounds good.

You act on instinct. Another taser dart whizzes past and you grab the cord out of the air; you yank it hard and pull the security guard off balance. In the same instant you're on your own feet, the stun gun flying into your hand like a yo-yo with another quick jerk of the cord.

A conduit in your palm opens and you grip the stun gun hard, pushing an electrical charge into its battery. It crackles in your hand, the battery swelling into a pillow and threatening to crack its plastic casing. Perfect.

"Catch," you say, and then you throw it at the other security guard at approximately Mach 4.

The stun gun explodes, electricity sizzling through the air and knocking the guards to the floor, motionless save for electrical muscle spasms as molten lithium polymer splatters over them.

"Holy shit!" your friend shouts. "C'mon, let's go!" He grabs your hand, apparently unafraid to touch you even after seeing what you just did, and the two of you keep running. Unfortunately you don't run for long--only a few yards, really.

"Oh--fuck," your friend says as you skid to a halt in front of a big, thick door marked EXIT; he mashes a keypad beside it and nothing happens except blinking red lights. And damn, the sirens are really starting to get on your nerves. "They've locked us in. I can't break this one down."

"I can't nap through this, can I?" you sigh.

"Not this time, buddy. Fuck," he says again. "I--okay, we might be able to hack our way out, but we'd have to stay here and do it and--you might have to fight off more security." He runs a hand through his long, fluffy hair, his chest heaving with exertion and adrenaline. "Or we can try getting out through the service exits, maybe they haven't locked those up yet, they're kinda out of the way, and, and we might be able to avoid more security going through the back but it'll take longer and it's probably locked anyway and--shit, E, you were kinda made for situations like this, right? What do we do?"
