California-based Rondo Energy and Thailand’s Siam Cement Group are going to operate the world’s largest battery factory in Thailand.

The world’s largest battery factory

The production capacity of Rondo Heat Battery storage at Siam Cement Group’s factory is going to be ramped up from 2.4 GWh to 90 GWh per year – that’s larger than any existing or planned battery manufacturing factory worldwide.

The existing 160,000 square meters (1.72 million square feet) factory is going to be expanded. A spokesperson told Electrek that the launch timeline is over the next few years, but the two companies have not yet committed to a set date.

The 90 GWh of planned capacity will result in 12 million tons of CO2 emissions savings annually, equivalent to removing over 4 million ICE vehicles from the road each year.

How the Rondo Heat Battery works

Siam Cement Group is the largest and oldest cement building material company in Southeast Asia. Its subsidiary SRIC produces refractory bricks. Also called fire bricks, refractory bricks are made of fireproof materials that can withstand high temperatures.

Each brick that Siam Cement Group makes for Rondo’s batteries (pictured above) is 500 kg and stores 100 kWh – as much as a Tesla Model X.

Rondo Energy, which is backed by Bill Gates-founded Breakthrough Energy Ventures and utility-backed Energy Impact Partners, launched its first commercial operating unit at an ethanol plant in Pixley, California, in March.

The Rondo Heat Battery captures intermittent electricity from solar and wind, stores the energy from that electricity as high-temperature heat in brick materials, and delivers the stored energy on demand as high-temperature heat and/or electricity:

The battery is made only of brick and iron. It charges in as little as four hours and stores heat energy at temperatures up to 1500° C for hours or days, delivering zero-carbon heat for such processes as steel, cement, and chemical manufacturing.

Rondo has designed its battery for such industries as steel, cement, grid energy storage, power plant conversion, and mining.

Here’s how Rondo says its batteries can reduce emissions in different sectors:

Raymond James energy analyst Pavel Molchanov said in a statement:

Electric thermal energy storage can play a useful role in addressing the needs of the industrial sector, which has been slow to decarbonize.

And, from an energy security standpoint, it is worth noting that this technology avoids the use of scarce and expensive materials.

Industry uses more energy than any other sector in the world, and most industrial energy is used as heat. Industrial heat consumes a quarter of total world energy and today releases a quarter of the world’s carbon dioxide emissions.

The Nissan Juke looks way better as an EV: Here’s your first look

The Nissan Juke looks way better as an EV: Here's your first look

Nissan-electric-Juke

Following the LEAF, the new all-electric Nissan Juke is next in line to receive a glow-up. The Juke EV was spotted for the first time rocking a new look ahead of its debut.

First look at the new electric Nissan Juke

Let’s be honest, the Juke wasn’t exactly what you’d call a head-turner. At least not for the right reasons. Nissan pulled the Juke from its North American lineup after the 2017 model year, replacing it with the Kicks.

The Juke is still Nissan’s second-best-selling vehicle in Europe, behind the Qashqai. As part of its up to £3 billion ($3.9 billion) investment to upgrade its Sunderland, UK plant, Nissan revealed plans to launch three new EVs: the LEAF, Qashqai, and Juke.

After launching the new, third-gen LEAF, Nissan plans to introduce the electric Juke in 2026 and Qashqai EV in 2027.

With its official debut coming up, the electric Nissan Juke was spotted for the first time out in public. Although it’s camouflaged, you can already see that it’s shaping up to be a big improvement over the outgoing Juke.

The images from Motor.es (you can view them below), reveal the EV version still has a profile similar to the current Juke, but the front and rear ends appear to be closer in style to the new LEAF. The grille is now closed off, and the front features Nissan’s new V-Motion front fascia. Meanwhile, the rear gains a new light bar connecting the taillights.

We also got a sneak peek at the interior, revealing dual central infotainment and driver-cluster screens. Like the LEAF, 12.3″ screens will likely come standard with 14.3″ screens available on higher trims.

Nissan has yet to reveal final specs or prices, but the electric Juke is expected to be based on the same CMF-EV platform as the new LEAF. The new Nissan LEAF is available in the UK with two battery options: 52 kWh and 75 kWh, offering WTLP ranges of 271 miles and 386 miles, respectively.

Although the electric Juke is set to arrive next year, an Automotive News report in August claimed Nissan may continue offering the gas version due to slower-than-expected EV demand.

Right behind it is Rad Power’s RadRover 6 Plus e-bike at a new $999 low, as well as Heybike’s ALPHA All-Terrain Mid-Drive e-bike getting $266 in FREE gear at a new $1,299 low, and the Ranger S Folding e-bikes (750W and 1,000W) down at annual lows starting from $999 – but keep in mind that these two are only staying at these rates for four days – plus, other ongoing early Black Friday deals waiting for you below. And don’t forget about the hangover deals that are collected together at the bottom of the page, like yesterday’s full Rad Power Black Friday e-bike sale lineup, the Jackery early Black Friday deals + an exclusive solo deal, and more.

Head below for other New Green Deals we’ve found today and, of course, Electrek’s best EV buying and leasing deals. Also, check out the new Electrek Tesla Shop for the best deals on Tesla accessories.

Save up to $600 in early Black Friday savings on Velotric e-bikes starting from $1,099

Velotric has launched its early Black Friday Sale with up to $600 in e-bike savings in the form of price cuts and FREE bundled gear. Among the lineup, we’re seeing a rare price cut on Velotric’s Discover 2 Step-Thru Commuter e-bike to $1,899 shipped, which is also getting $120 in FREE gear. In 2025, the MSRP on this newer model increased from $1,899 to $1,999 from tariff hikes, with the largest discount we saw in 2024 being a one-time drop of $200, while we’ve only seen one previous cut to $1,899 that happened back in August. Today’s deal is bringing back that same second-best rate, giving you $100 off the tag while also providing you with a $120 FREE suspension seat post. Head below to check out Velotric’s full early Black Friday lineup.

The second-generation of Velotric’s flagship Discover 1 Plus model (which has been sold out since the Prime Sale last month), the Discover 2 commuter e-bike is a more advanced solution that still retains a reasonable price despite its notable upgrades. Things start at the newer 750W 75Nm rear hub motor (peaking to 1,100W) alongside a 705.6Wh battery to reach up to 20/28 MPH top speeds (depending on your state’s laws) and provide pedal-assistance support for up to 75 miles on a full charge. One big improvement here is the SensorSwap tech that lets you switch between a cadence or torque sensor as you need them, with the PAS boasting three modes that each have five levels.

There’s plenty more to love about this model, with additional features including Apple Find My integration, hydraulic disc brakes, Kenda puncture-resistant tires, an auto-on integrated LED headlight, a rear cargo rack with an integrated taillight (complete with turn signaling, as well as brake, flashing, and steady lighting), an 8-speed Shimano Altus derailleur, a 3.5-inch full-color display with a USB-C port, and more.

Velotric’s early Black Friday deals on new e-bikes:

  • Fold 1 Plus Folding e-bike: $1,499 (No price cut)

Rad Power’s RadRover 6 Plus e-bike gets $600 Black Friday discount to a new $999 low (Reg. $1,599)

As part of Rad Power’s ongoing Black Friday Sale that will only last as long as supplies hold out, we wanted to shine a spotlight on the RadRover 6 Plus Step-Thru Fat-Tire e-bike at $999 shipped. You’d be paying a full price of $1,599 outside of sales, with the discounts we’ve seen this year having taken things down between $1,399 and $1,299, with some rare cuts as low as $1,199. Now, with these early Black Friday savings, we’re seeing it go lower than ever with a $600 markdown that lands $200 under the former low for the best new price that we have tracked.

As part of Heybike’s ongoing early Black Friday Sale, and running alongside the short-term Ranger S $999 annual low, there is also a 4-day flash sale on the ALPHA All-Terrain Mid-Drive e-bike at $1,299 shipped with it also getting $266 in FREE gear. It carries a $1,699 MSRP, but over the year, we’ve regularly seen it drop to $1,599 and $1,499, with a flash sale that took things to $1,399 last month for the first time. Now, during this 4-day window, you can score a larger-than-ever $400 markdown that drops things to a new all-time low price. On top of this price cut, you’re also getting a steel cable lock, helmet, a waterproof backpack, a large cargo basket, and a gift pack.

Heybike’s 4-day early Black Friday flash sale cuts $500 off Ranger S folding e-bikes to $999 and $1,199 annual lows

As part of Heybike’s early Black Friday Sale, the brand is giving folks a 4-day flash sale on two models, with a surprise price cut on the Ranger S 750W Folding Fat-Tire e-bike to $999 shipped that also comes with a FREE Black Friday gift pack, or you could go with the upgraded 1,000W variant at $1,199 shipped and get the same gift pack. These two models would normally run you $1,499 and $1,699 at full price, which discounts have almost exclusively dropped as low as $1,099 and $1,299 over the year, if not at higher rates. While we have seen the price go as low as $899 and $1,099 in the past, those rates haven’t been seen since last year, making the $500 markdowns here the best prices we’ve tracked in 2025.
