As IoT technology progresses, the question of how to power these devices, particularly in locations where reliable electrical sources are scarce, presents a significant challenge.
Researchers at the University of Utah’s College of Engineering have pioneered a new form of battery that could help solve this dilemma. The solution, which is at the proof of concept stage, comes in the form of a pyroelectrochemical cell (PEC).
Developed by associate professors of mechanical engineering Roseanne Warren and Shad Roundy, the integrated device harvests ambient thermal energy and converts it into stored electrochemical energy. This effectively creates a supercapacitor or battery, which could be ideal for IoT and sensor applications.
Low levels of energy
The device works by charging with changes in its surrounding temperatures, whether located inside a vehicle, an aircraft, or even underneath soil in an agricultural environment.
“We’re talking very low levels of energy harvesting,” Warren said, “but the ability to have sensors that can be distributed and not need to be recharged in the field is the main advantage. We explored the basic physics of it and found that it could generate a charge with an increase in temperature or a decrease in temperature.”
Whilst solar cells can provide an alternative power source of IoT devices, the practicalities often present issues. “In a lot of environments, you run into two problems,” said Roundy. “One is that it gets dirty over time. Solar cells have to be kept clean. So in these types of applications, they get dirty and their power degrades. And then there are a lot of applications where you just don’t have sunlight available. For example, we work on soil sensors that we put just under the top surface of the soil. You’re not going to get any sunlight.”
With the use of a pyroelectric composite material made of porous polyvinylidene fluoride (PVDF) and barium titanate nanoparticles as the separator in an electrochemical cell, the device’s electrical properties change as it’s heated or cooled. This action modifies the polarization of the pyroelectric separator. This shifting of temperatures in turn creates an electric field within the cell, moving ions around and allowing the cell to store energy.

Despite only producing up to 100 microjoules per square centimeter from a single heating/cooling cycle, this could be enough for the needs of some IoT applications.
The study, funded by the National Science Foundation, is the cover feature in the March 21 edition of the journal Energy & Environmental Science, published by the Royal Society of Chemistry.
Batteries are ubiquitous – in one form or another, they’re powering a lot of our wireless tech. That also means we’re throwing out a lot of batteries once they’ve been drained, which isn’t doing our environment any favors.
Many of us have opted for rechargeable batteries to power some of our devices, from TV remotes and flashlights, even some toys. Not enough of us, though. According to data published in 2018, only about 30% of Americans had adopted rechargeable batteries by then. It’s a similar situation in Australia, with only 30% of the batteries purchased being the rechargeable kind. And less than 2% of these are the popular AA and AAA sizes.
One company trying to ensure the number of batteries we throw out diminishes as much as possible is Paleblue Earth. Based out of Park City, Utah, the company’s aim is to offer a battery with superior long-term performance so you not only help protect the planet but also save money in the process.
Available in AA, AAA, C, D, 9V and CR-123A sizes, Paleblue batteries stand apart from the rechargeable competition by offering USB-C charging.
Batteries with a difference
Each Paleblue battery comes with a USB-C port, so you can top them up any time and anywhere via a portable power bank. Along with the batteries you buy, the company ships a USB-A cable with 2 to 4 split USB-C ends, which means there’s no need for a separate charging cradle. In other words, you’re also cutting down on using a bulky product that was made using non-recyclable materials and would also end up in the landfill at some point.
Paleblue batteries can fully recharge in about 1.5 hours, which is faster than other rechargeable alternatives on the market.
Given they’re lithium-ion as opposed to Nickel Metal Hydride (NiMH) or alkaline, which are the more popular rechargeable options, they’re they safer and more stable variety too.

They’ve also been designed for longer-term performance, with the company offering a lifetime warranty on its products, something we don’t see other battery makers do. The company claims that each Paleblue battery offers 1,000 charging cycles, meaning one can replace 1,000 single-use batteries. Paleblue sells four-packs of its batteries (even 8 and 12 if you need more), which can equate to keeping 4,000 disposable batteries out of landfill!
Moreover, the packaging they come in is recyclable, plus you get a handy box to store them in.
Paleblue batteries aren’t cheap though – a AA 4-pack will set you back $23.99 / AU$49.95 for example. In comparison, Duracell’s 4-pack of AA size batteries will cost about $15 / AU$29. The flip side to this is that Duracell guarantees only 400 recharge cycles compared to Paleblue’s 1,000.
Are rechargeable batteries really sustainable?
Despite being considered the more environmentally friendly option, rechargeable batteries are, in fact, more toxic than single-use ones. Their long-term usability, however, compensates for their toxicity.
A study conducted by the Polytechnic Institute of Milan found that a rechargeable battery needs to be charged about 50 times to offset its environmental impact. This was supported by an article published on Yale University’s Climate Connections site, which said that if a rechargeable battery was thrown out after only 5-6 cycles, it’s far more toxic than disposable ones.
Rechargeable batteries aren’t the perfect solution, but they’re the lesser evil for now. Countries around the world have set up battery recycling programs – in the US, you can get in touch with Call2Recycle, while in the UK and Australia, there are collection bins in tech retail outlets where you can drop them off.
And while they might cost more upfront, the amount of use you get out of them can save you around 400 times the amount you spent on them.

The Seattle ebike company Rad Power Bikes has announced four new ebike models, all of which have the very important distinction of being unlikely to have their batteries suddenly burst into flames.
The company says its new Safe Shield Batteries—which come standard on all four new bikes—have been certified at UL-2271, an industry standard ranking for battery safety. That means the batteries on these models of Rad Power’s bikes won’t be nearly as susceptible to the kinds of battery fires that have been plaguing low-end ebikes and scooters and have led to injuries and nearly 20 deaths in the US.
Rad Power had 30,000 of its RadWagon 4 ebikes recalled in 2022 due to misaligned tires, an issue the company has apologized for and says it has fixed. There’s been one reported case of a Rad Power bike catching fire, but other than that the company hasn’t contributed to the wave of cheap ebike battery fires. We tend to like Rad Power’s bikes quite a bit here at WIRED, so this increase in battery safety is welcome news, especially because of the added emphasis on the whole “not exploding” thing.

Rad Power’s new bikes come in a few forms. There’s its Radster commuter bike, which comes in Road and Trail models for different terrains. Both start at $1,999. The company also announced the RadExpand 5 Plus, an $1,899 folding bike, and its new iteration of the cargo-oriented RadWagon 5, which starts at $2,199.
Here’s some other consumer tech news from this week.
Ask Wendy’s Anything
Reddit is trying to make itself friendlier to marketers. This week, the company announced a new suite of tools, called Reddit Pro, that will be available to businesses for free.
Reddit Pro offers brands a variety of ways to engage with the platform’s users, in service of helping advertisers better pour themselves into every eyeball remotely possible. For instance, Reddit will offer “AI-powered insights” that the company says will sift through the site’s 17 billion posts to find relevant threads and topics that companies can then use to “join or start conversations” (aka deploying their deeply cringe marketing tactics). That means when you write a comment about, say, Wendy’s, in a thread way down on a tiny subreddit, the brand’s social media team will have an easier time finding it and spouting off some sassy brand banter in the replies.
It’s the latest move in Reddit’s slow, controversial quest for profitability (and possibly enshittification). Reddit filed to take the company public in February, which will enable it to sell stock to shareholders. The company, which has never proven profitable, is eager to make its platform more appealing to advertisers who can spend money in its forums. This is likely why Reddit has made moves like charging an exorbitant amount of money for the tools developers use to access the platform’s data, effectively killing third-party apps. This move of giving brands and advertisers an easier portal into every segment of the site is another stab at those ambitions.
Dodge This
There’s a new Dodge chargin’ onto the scene. Yes, it’s a Charger, the beefy, grotesquely fuel-inefficient muscle car that’s been roaring across roads for the better part of the past century. In 2021, Dodge announced it would ditch its gas-powered Chargers in favor of electric variants. This week, the first stage of that rollout has officially begun.
Billed—somewhat arguably—as “the world’s first and only electric muscle car,” the Dodge Charger Daytona Scat Pack EV is an absolutely juiced-up road-rage machine that’s bound to be the closest thing you can get to driving a Transformer. It boasts up to 670 horsepower and has a quoted zero-to-60 time of 3.3 seconds. The car also comes with an array of features meant to make it easier to mainline high-octane driving adrenaline. There are dedicated performance modes for rubber-burnin’ excursions like Drag, Track, Drift, and Donut modes. Another setting, called PowerShot, increases horsepower by 40 hp for 15 seconds. It’s like injecting your car with nitrous oxide but keeping it street legal.
Nikon Takes a Red Eye
Camera manufacturer Nikon announced this week that it is scooping up the cinematic camera company Red. Red’s professional digital cameras have a long reputation in cinematography circles for pushing the boundaries of what camera sensors and optics can do. They’re traditionally expensive, beefy devices aimed at professionals producing cinema-quality content. If you watch any big-budget shows or movies on network television or the streamers, you’ve surely seen something shot on Red.
This move by Nikon points to the company’s video ambitions. Nikon makes very good photography cameras but has struggled to compete with the likes of Canon when it comes to video. Buying a premium video-camera company may certainly give the brand a leg up.
Hey Google, U OK?
There’s always lots going on at Google. As one of the biggest tech firms in the world, the company often attracts a lot of scrutiny and criticism, much of it warranted. But Google’s been on a roll lately, with problems stemming from its rush to push out AI products, its recent rounds of layoffs, and internal discrimination against its own employees. All of this makes for a very chaotic time for the company, which raises the ultimate question: Is Google OK?
This week on WIRED’s Gadget Lab podcast, we talk about the online uproar about Google’s Gemini AI going “woke” and all the internal turmoil roiling the big Silicon Valley company.
During the holiday season more batteries than ever are consumed, powering our electronic devices, children’s toys and more.

For those who use devices in extreme temperatures, lithium batteries are the better choice. They perform reliably in harsh weather conditions, unlike alkaline batteries, which may falter. This makes lithium batteries a dependable option for outdoor enthusiasts and professionals who need their equipment to work in unpredictable climates.
Battery life
Another important aspect is the durability and shelf life of the battery. Lithium AA batteries not only last longer when in use but also have a longer shelf life. This means you won’t need to replace them as often, which could save you money over time, even though they are more expensive initially.
Economic and environmental
When considering the economic impact, it’s important to look beyond the upfront cost. Lithium batteries might cost more at the outset, but their extended lifespan can lead to savings in the long run, especially for devices that drain batteries quickly.
The environmental considerations and disposal of batteries are also critical. Lithium batteries may produce less waste due to their longer lifespan, but they require careful disposal and recycling because of their chemical content. Alkaline batteries may not last as long, but they are generally easier to dispose of and present fewer environmental hazards if not recycled correctly.
Conclusion
Ultimately, the decision between lithium and alkaline AA batteries depends on the specific needs of your device and your personal preferences. Lithileum batteries are ideal for high-drain devices, extreme conditions, or when it’s important to keep weight to a minimum. Alkaline batteries might be better for low-drain devices and those on a tight budget. No matter which type you choose, it’s important to be aware of the environmental impact and to recycle whenever possible to reduce your ecological footprint.
