Brits with EVs to charge their car much faster following huge breakthrough
A game-changing technological advancement could see the batteries in electrical vehicles (Evs) charge significantly faster and last longer - luring even more Brits to make the eco-friendly switch UK motorists whizzing around in electric vehicles (EVs) could soon see a huge battery boost thanks a major tech breakthrough. The innovation comes from 24M Technologies — the American battery specialists have developed a new electrolyte called Eternalyte, which holds the key to this amazing advancement. This new material is responsible for how quickly ions move between the battery's two main parts, the anode and cathode. The faster these ions can move, the faster the battery can charge. Eternalyte can achieve up to three times the ionic conductivity of standard electrolytes. In simpler terms, this means ions can travel much more quickly inside the battery, speeding up the charging process without sacrificing the energy storage capacity. 'I've had an EV for one year and small feature still scares me - it's not range' Thanks to this leap in conductivity, 24M says batteries using Eternalyte can charge four times faster than conventional ones, allowing drivers add over 300 kilometres of range in under four minutes, without needing ultra-powerful megawatt charging stations that are not yet widely available in the UK and Europe. This means our existing charging infrastructure will be enough to deliver these rapid charging times. Another big advantage of Eternalyte is how well it performs in cold weather. At 0°C, regular EV batteries can lose around 25 per cent of their capacity, while at even lower temperatures, they may lose nearly all of it. On the other hand, Eternalyte keeps nearly all its capacity at 0°C and still holds more than 80 percent at -40°C. This addresses a major frustration for EV owners in winter, as well as those who live in colder parts of the UK — where battery range and performance can drop sharply in freezing conditions. President and CEO of 24M Technologies, Naoki Ota, explained: "24M's Eternalyte electrolyte breakthrough solves some of the biggest challenges of lithium-ion batteries today. "Rapid charge, superior low-temperature performance and great cycle life with lithium-metal and other high energy density chemistries, Eternalyte provides outstanding performance for applications ranging from EVs to consumer products. It paves the way for next-gen batteries, including lithium metal, with 1,600-kilometre driving range and years of reliable performance." Originally designed for lithium metal batteries, Eternalyte is also suitable for the silicon and graphite-based batteries found in most EVs today. It can be integrated into current battery manufacturing processes, so car makers could adopt the technology without major changes to their factories. When paired with 24M's Impervio separator, Eternalyte also makes batteries safer and extends their lifespan, helping to prevent dangerous problems including battery fires. So, this brilliant breakthrough could soon make EVs much more convenient for British drivers, with ultra-fast charging and reliable performance whatever the weather — and all without needing to wait for new and improved charging stations to be built.

A company is developing a fancy electrolyte to charge EV batteries four times faster
Electric A groundbreaking thing might have just happened for electric car batteries Skip 3 photos in the image carousel and continue reading A company called 24M Technologies has created an electrolyte called Eternalyte that it reckons will revolutionise the way electric car batteries work. Big claims, but it might be onto something. Rather than switching out to a solid-state electrolyte, this special sauce (the recipe for which is kept under wraps) makes the ions move between the anode and cathode more quickly and at a greater rate. Advertisement - Page continues below The result? A charge rate four times faster than conventional batteries, giving around 186 miles of juice in less than four minutes, using – get this – standard charge points. Yup, there's no need for ultra-fast charging infrastructure. Granted, 24M's own spec sheet states the gravimetric energy density of the battery cell is 350Wh/kg, and Merc's working on solid-state batteries with 450Wh/kg power density. Still, 24M's proprietary liquid electrolyte has other cool properties, literally. Where cold weather can reduce current battery capacity by about 25 per cent at freezing point, the boffins at 24M reckon Eternalyte helps a battery maintain all of its usability at 0°C and more than 80 per cent capacity if you get down as low as -40°C. Since we haven't any polar expeditions planned, we'll take their word for it. You might like Eternalyte has been developed for lithium-ion batteries, but the laboratory tests have shown similar results in lithium-metal, silicone-based and graphite-based batteries, too. There's also improvement in the battery lifecycle. Naoki Ota, 24M Technologies boss, said: "24M's Eternalyte electrolyte breakthrough solves some of the biggest challenges of lithium-ion batteries today. Rapid charge, superior low-temperature performance and great cycle life with lithium-metal and other high energy density chemistries, Eternalyte provides outstanding performance for applications ranging from EVs to consumer products.

Battery experts warn electric car fires will increase unless decades-old technology is improved
Battery experts have sounded the alarm on a rise in the number of electric car fires, predicting there could be 25,000 instances per year by 2030. While evidence shows they are currently far less frequent than infernos involving internal combustion engine (ICE) cars, they pose major safety concerns as EV fires are far more dangerous. They are more likely to take place when a vehicle is parked or during charging and EV blazes are also incredibly difficult to extinguish. According to the International Energy Agency, there are 40 million EVs on the world's roads today. However, this is forecast to reach 250 million by 2030. 'Even at a conservative rate of one fire per 10,000 EVs, thermal incidents could reach 25,000 per year worldwide by the end of the decade,' experts at 24M Technologies said on Thursday. This predicted rise in cases will significantly increase risk to public safety, as well as car manufacturer profitability, unless major upgrades are made to battery cell design to reduce the risk of fires, it warned. The UK fire service last year reported a 33 per cent year-on-year increase in electric car blazes in Britain. 24M Technologies, which specialises in battery cell design, says the industry's current safety challenges 'stem from decades-old battery principles' that are unchanged for the last 30 years. The battery maker, which formed in 2010 in a spin-off from MIT, attributes the increasing risk of EV fires to a combination of the rising number of electric cars on the road and battery cell energy densities growing dramatically to provide longer ranges between charges. The latter requires 'energy richer materials and smaller cell component safety margins', the company said, as it suggested manufacturers' best efforts to prevent blazes with existing battery technology is falling short. 'These issues, as well as the growth in ever faster charging capabilities, increases the threat of internal short circuits, which cannot be stopped externally,' it claimed. As well as posing a greater threat to public safety, 24M Technologies says there are also huge financial ramifications at play for automakers. This is because recalls related to EV fires carry an estimated price tag of $1billion (£750million) per vehicle model line. As such, it says cell design must be 'reimagined to be fundamentally safer'. Naoki Ota, President and CEO at 24M Technologies said: 'The industry's current safety challenges stem from decades-old battery design principles. 'While we've achieved remarkable progress in cost reduction and energy density, we're still building upon architectures that have not fundamentally changed in more than 30 years. 'Process improvements alone cannot address these design limitations and multiple OEMs [Original Equipment Manufacturers] have faced costly recalls as a result.' Ota adds: 'Rather than address these issues through add-on system features, safety must be incorporated as a foundational element at the core of the battery cell.' EV FIRES ATTENDED BY UK FIRE SERVICE IN 2022-2023 2022 2023 YOY increase Fires linked to lithium-ion batteries 630 921 46% Fires involving an e-bike 158 270 70% Fires involving an e-scooter 117 125 7% Fires involving an electric car 89 118 33% Fires involving an electric bus/coach 18 22 22% Fires involving an electric truck 3 12 300% Source: QBE Freedom of Information (FOI) request on 31 January to 50 UK fire services, receiving data from 42 What triggers EV blazes? Batteries that power electric vehicles such e-bikes, e-scooters and electric cars were involved in almost three fires a day in 2023, compared to under two fires a day in 2022, it was revealed last year. An investigation by international insurer QBE revealed that electric car blazes attended by UK fire services grew from 89 cases in 2022 to 118 instances the following year. Fires in lithium batteries typically used for today's EVs often occur because of 'dendrite' growth in cells. These are tree-like structures of lithium metal that grow inside the battery, especially during charging, and can trigger a short circuit, resulting in a blaze. They also impact battery performance and lifespan. Dendrites are inevitable over a battery's lifecycle as it ages and undergoes thousands of charge and discharge cycles and can also occur as a result of overcharging, charging at very low temperatures or frequent fast charging. A short circuit - which is called a 'thermal runaway' in EVs - will cause a battery cell to overheat, releasing flammable gases which then ignite. It only takes one cell to overheat, which can happen in milliseconds. When a thermal runaway event begins, it impossible to stop without intervention. And once one cell is impacted, it can quickly spread to others before engulfing the entire battery and ultimately the vehicle. When ablaze, lithium batteries require more effort to be extinguished because the batteries can generate enough heat to reignite after the initial fire has been put out. These 'dormant phases' can last for hours before they relight, experts warn. And such high temperatures can cause gassing of the battery and blazes so hot that they become extremely difficult to put out. A statement from the National Fire Chiefs Council (NFCC) explains: 'The reignition of batteries is possible after prolonged periods, after mechanical shock, heating or battery faults. 'They may require extended periods of cooling and monitoring after a fire or collision. 'Damaged batteries can be too sensitive to move, and personnel may have to consider cordoning off a vehicle and handing it over to a responsible person.' Because of this, traditional firefighting methods often prove ineffective when trying to extinguish EV blazes. As such, the NFCC has a bespoke set of guidelines for fire service crew to deal with fires with electrified cars. Various fire services across Europe and around the globe have invested in transportable plunge pools for EVs to submerge them in water to reduce the battery temperature and kill the flames quicker. How to reduce the risk of battery fires Mr Ota, a recognised global expert in lithium-ion batteries, says the only solution to prevent EV battery fires is to incorporate in-cell fire prevention technology. 24M has developed a system - called Impervio - which it claims is 'uniquely capable of suppressing dendrites and neutralising thermal runaway' before it can start. He explained: 'Unlike other technologies, it not only monitors individual cells but prevents thermal incidents. 'The industry must shift from reactive measures to try to contain fires to proactive designs preventing failures before they occur. 'Without this step change approach, the safety and financial challenges will only intensify as EV adoption accelerates.' It claims the non-Impervio cells (pictured bottom) began to shorts after 15 minutes, with the cell catching fire and exploding after 38 minutes. Whereas its tech (top) did not set ablaze after an hour over 100% overcharging The US battery designer says it has already conducted side-by-side test of battery cells with Impervio and one without. These were charged to 100 per cent, then to 100 per cent overcapacity to dramatically increase the risk of dendrite growth. It claims the non-Impervio cells began to shorts after 15 minutes, with the cell catching fire and exploding after 38 minutes. However, cells with the company's tech saw 'negligible temperature increase, did not short and did not catch fire – even after an entire hour of overcharging,' it reports.
