Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance, hybrid sodium-ion battery that charges rapidly and offers impressive energy density.
This revolutionary prototype uses sodium (Na), a chemical element over 1000 times more abundant and cheaper than lithium (Li), the main component of conventional batteries.
Generally, sodium-ion batteries face constraints such as lower power output, limited storage properties, and extended charging times. The innovative battery design, led by Professor Jeung Ku Kang of the Department of Materials Science and Engineering at KAIST, combats existing limitations of sodium-ion batteries by integrating the anode materials used in traditional batteries with the cathodes used for supercapacitors into a hybrid system. The result reportedly delivers high storage capacity and rapid charge-discharge rates.
Multiple possibilities
Developing the hybrid battery hinged upon improving the energy storage rate of battery-type anodes and boosting the relatively low capacity of supercapacitor-type cathode materials.
The research team at KAIST made use of two distinct metal-organic frameworks to create an optimized synthesis of hybrid batteries, culminating in anode material with improved kinetics and a high-capacity cathode material.
The fully assembled hybrid sodium-ion energy storage device reportedly surpasses the energy density of commercial lithium-ion batteries and matches the power density characteristics of supercapacitors. Professor Kang says this new battery, with an energy density of 247 Wh/kg and a power density of 34,748 W/kg, could be used across a range industries, including electric vehicles, smart electronics and aerospace technologies.
The findings of this research, co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, were published in the international journal Energy Storage Materials with the catchy title of “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface-area O-doped cathode of 3D porous N-rich graphitic carbon frameworks for high-performance sodium-ion hybrid energy storages.”

Formula E is halfway through its Gen3 car cycle and plans are in motion for the upcoming Gen4 racer. However, the series isn’t waiting until that all-new electric car is ready to hit the track to debut some significant upgrades to the current model. Ahead of the Monaco E-Prix this weekend, Formula E debuted what it calls the Gen3 Evo, the fastest accelerating FIA single seater in the world by current standards. The series is also introducing body changes aimed at improving aerodynamics and durability, particularly to the nose, along with all-wheel drive (AWD) for the first time on a Formula E car.
Formula E says the Gen3 Evo is capable of accelerating a full second faster than the Gen3 version, going from 0 to 60 mph in 1.82 seconds (0-100 kph in 1.86 seconds). It explained that that time is 30 percent faster than a 2024 Formula 1 car and 36 percent faster than the Gen3 EV currently used in races. Those numbers aren’t theoretical either: the series has already achieved the benchmarks on track in Misano, Italy.
“It’s not simulated, it’s real,” Formula E CEO Jeff Dodds told Engadget. “It was really timed by the FIA at that speed.” Dodds added that there were some “slight tweaks” in some areas, but the Gen3 Evo should still hit 60 mph in under two seconds when it debuts on track for races next year.
A key aspect of this unlocked acceleration is the use of AWD on a Formula E car for the first time. The series debuted dual powertrains with Gen3, but until now, the one up front was only being used for battery regeneration. AWD will only be used during the later rounds of qualifying (head-to-head duels), the race start and when a driver has activated Attack Mode during the race. Besides the boost to acceleration, drivers should have better control and more grip when AWD is active. Plus, it entirely changes team strategy and could lead to even more exciting racing.
“One of the occasional criticisms I hear is Attack Mode doesn’t have a big enough difference,” Dodds said. “I think with all-wheel drive, that will make a difference.” He also noted that when you have 22 cars that are all capable of 0 to 60 mph in under two seconds barreling towards turn one, “that makes for a high jeopardy, exciting start of a race.”

One frustration of Gen3 that Formula E is addressing with the Gen3 Evo is the fragility of the front wing. As part of a larger overhaul to the body that includes new side pods, rear wing and more, the new car has a redesigned, slightly pointier nose and a strengthened front wing. With the Gen3 car, front wing damage is common, and it often gets stuck under the car, which becomes dangerous for a driver trying to make his way back to the pit lane. In addition to being “stronger” and “more robust,” according to Formula E, the body changes also improve aerodynamics, which could contribute to more wheel-to-wheel battles on track.
Another key change is to the tires. Formula E is still working with Hankook on the all-weather compound used for its races, but the updated version offers 5- to 10-percent more grip compared to the current spec. Dodds explained that this increase in traction is essential since Gen3 Evo employs the front powertrain for AWD.
“If you haven’t got the increase in grip on the tires, that’s pretty challenging to control,” he said.
In total, Formula E says the performance upgrades on the Gen3 Evo equate to a two-second drop in qualifying lap times around the tight, twisty Monaco street circuit. Since the series stipulates qualifying time in that estimate, that means AWD and a higher power mode would be active to achieve it. But, it also means Formula E is unlocking the full potential of what Gen3 has been capable of since its debut last season.

Indeed, the bulk of the Gen3 car is still intact. That includes an all-electric race car that’s incredibly efficient, converting 90 percent of its energy to mechanical power. By employing 600kW regenerative braking, the cars produce almost 50 percent of the energy they need to complete a race while on track. Like its predecessor, the Gen3 Evo remains capable of a top speed of 200 mph. And just like before, teams will make performance updates to the cars via software changes in search of any on-track advantage.
Formula E says there has already been some driver testing of the Gen3 Evo behind closed doors, and the feedback has been very positive. Dodds explained that Tag Heuer Porsche’s Pascal Wehrlein and DS Penske’s Jean-Éric Vergne both drove the car in test sessions with rave reviews. Vergne, who is one of the more outspoken drivers on the grid, specifically noted how much better it drives than the current car.
“The sooner we can get to [Gen3 Evo] in season 11, the better, as far as he’s concerned,” Dodds explained. “It’s lovely to get that feedback, because happy drivers often create happy races.”
OpenAI has been rapidly developing its ChatGPT generative AI chatbot and Sora AI video creator over the last year, and it’s now got a new artificial intelligence tool to show off: Voice Generation, which can create synthetic voices from just 15 seconds of audio.
In a blog post (via The Verge), OpenAI says it’s been running “a small-scale preview” of Voice Engine, which has been in development since late 2022. It’s actually already being used in the Read Aloud feature in the ChatGPT app, which (as the name suggests) reads out answers to you.
Once you’ve trained the voice from a 15-second sample, you can then get it to read out any text you like, in an “emotive and realistic” way. OpenAI says it could be used for educational purposes, for translating podcasts into new languages, for reaching remote communities, and for supporting people who are non-verbal.
This isn’t something everyone can use right now, but you can go and listen to the samples created by Voice Engine. The clips OpenAI has published sound pretty impressive, though there is a slight robotic and stilted edge to them.

Worries about misuse are the main reason Voice Engine is only in a limited preview for now: OpenAI says it wants to do more research into how it can protect tools like this from being used to spread misinformation and copy voices without consent.
“We hope to start a dialogue on the responsible deployment of synthetic voices, and how society can adapt to these new capabilities,” says OpenAI. “Based on these conversations and the results of these small scale tests, we will make a more informed decision about whether and how to deploy this technology at scale.”
With major elections due in both the US and UK this year, and generative AI tools getting more advanced all the time, it’s a concern across every type of AI content – audio, text, and video – and it’s getting increasingly difficult to know what to trust.

As OpenAI itself points out, this has the potential to cause problems with voice authentication measures, and scams where you might not know who you’re talking to over the phone, or who’s left you a voicemail. These aren’t easy issues to solve – but we’re going to have to find ways to deal with them.
