CATL, the world’s leading battery manufacturer, continues proving why it’s the best with the biz. Today, the company unveiled a 20-foot-tall energy storage system (ESS) called the TENER Stack, which, according to CATL, offers breakthroughs in storage capacity, deployment flexibility, safety, and transportation efficiency. It also has the energy storage capabilities to charge 150 EVs.
As the undisputed global leader in battery manufacturing, CATL is constantly looking for new and exciting technologies to stay ahead of its competitors. Those innovations span nearly all mobility segments, from electric vehicles to electric planes, chargers, battery swap stations, and energy storage systems.
Just last month, CATL unveiled a new EV battery that could charge as fast as a trip to the gas station. In April 2024, CATL unveiled a 6.25 MWh capacity energy storage system called TENER, promising zero degradation in the first five years of use—the first of its kind.
Today, CATL has unveiled an even more robust version called the TENER Stack. Standing 20 feet tall, this ultra-large capacity ESS offers several key improvements en route to mass production.

CATL’s TENER Stack can power a home for six years
CATL shared details and images of the TENER Stack following a recent unveiling event. The towering energy storage system offers a “world’s first” storage capacity of 9 MWh supported by CATL’s high-energy-density LFP cells.
While the Stack still offers the same five-year zero degradation guarantee as its TENER predecessor, CATL shared that the newer model offers a 45% increase in volume utilization and a 50% increase in projected energy density compared to other systems of its size.
As such, the TENET Stack’s stored energy can charge 150 EVs or power the average German home for six years. Per Amanda Xu, CTO ESS & President of ESS Europe CATL:
CATL has always been at the forefront of the energy transition. To meet the expectation of a BESS system that has high energy density, small footprint, simpler AC-side configuration, and flexible deployment, we bring the latest CATL TENER energy storage solution. It breaks the limitations of power capacity and product transportation, and makes breakthroughs in space utilization, energy efficiency, and cost.
Due to their massive size and weight, ESSs like the TENER can face logistical hurdles, as transport containers must weigh less than 36 tons in many countries. To combat this, CATL has developed a “two-in-one” design in which each half-height unit remains weight compliant, enabling transport across 99% of all global markets.
That’s also where the “stack” term comes in, as this split design can be reassembled at its final destination, enabling the full brunt of its whopping 9 MWh capacity.
The TENER Stack joins the TENER and TENER Flex in a growing lineup of revolutionary energy storage systems to support the ever-increasing demand for global energy needs. It doesn’t appear to have reached the ceiling of its storage technology yet, either. Per Hank Zhao, CTO of ESS Europe CATL:
TENER Stack, giant, flexible, reliable and quiet. We are not only delivering an energy storage product, but a solution for energy accessibility that can be applied globally. 9 MWh is not the limit of the energy capacity or space. Every breakthrough in energy density in the future will unleash greater energy value from a smaller footprint.
The TENER Stack energy storage system is slotted for mass production at CATL ESS Europe in 2025.

Hyundai is getting ready to shake things up. A new electric crossover SUV, likely the Hyundai IONIQ 2, is set to debut in the coming months. It will sit below the Kona Electric as Hyundai expands its entry-level EV lineup.
Is Hyundai launching the IONIQ 2 in 2026?
After launching the Inster late last year, Hyundai is already preparing to introduce a new entry-level EV in Europe.
Xavier Martinet, President and CEO of Hyundai Europe, confirmed that the new EV will be revealed “in the next few months.” It will be built in Europe and scheduled to go on sale in mid-2026.
Hyundai’s new electric crossover is expected to be a twin to the Kia EV2, which will likely arrive just ahead of it next year.

It will be underpinned by the same E-GMP platform, which powers all IONIQ and Kia EV models (EV3, EV4, EV5, EV6, and EV9).
Like the Kia EV3, it will likely be available with either a 58.3 kWh or 81.4 kWh battery pack option. The former provides a WLTP range of 267 miles while the latter is rated with up to 372 miles. All trims are powered by a single electric motor at the front, producing 201 hp and 209 lb-ft of torque.

Although it may share the same underpinnings as the EV2, Hyundai’s new entry-level EV will feature an advanced new software and infotainment system.
According to Autocar, the interior will represent a “step change” in terms of usability and features. The new system enables new functions, such as ambient lighting and sounds that adjust depending on the drive mode.

It’s expected to showcase Hyundai’s powerful new Pleos software and infotainment system. As an end-to-end software platform, Pleos connects everything from the infotainment system (Pleos Connect) to the Vehicle Operating System (OS) and the cloud.
Pleos is set to power Hyundai’s upcoming software-defined vehicles (SDVs) with new features like autonomous driving and real-time data analysis.

As an Android-based system, Pleos Connect features a “smartphone-like UI” with new functions including multi-window viewing and an AI voice assistant.
The new electric crossover is expected to start at around €30,000 ($35,400), or slightly less than the Kia EV3, priced from €35,990 ($42,500). It will sit between the Inster and Kona Electric in Hyundai’s lineup.
Hyundai said that it would launch the first EV with its next-gen infotainment system in Q2 2026. Will it be the IONIQ 2? Hyundai is expected to unveil the new entry-level EV at IAA Mobility in September. Stay tuned for more info. We’ll keep you updated with the latest.

Tesla has unveiled its lithium-iron-phosphate (LFP) battery cell factory in Nevada and claims that it is nearly ready to start production.
Like several other automakers using LFP cells, Tesla relies heavily on Chinese manufacturers for its battery cell supply.
Tesla’s cheapest electric vehicles all utilize LFP cells, and its entire range of energy storage products, Megapacks and Powerwalls, also employ the more affordable LFP cell chemistry from Chinese manufacturers.
This reliance on Chinese manufacturers is less than ideal and particularly complicated for US automakers and battery pack manufacturers like Tesla, amid an ongoing trade war between the US and virtually the entire world, including China.

As of last year, a 25% tariff already applied to battery cells from China, but this increased to more than 80% under Trump before he paused some tariffs on China. It remains unclear where they will end up by the time negotiations are complete and the trade war is resolved, but many expect it to be higher.
The automaker had secured older manufacturing equipment from one of its battery cell suppliers, CATL, and planned to deploy it in the US for small-scale production.
Tesla has now released new images of the factory in Nevada and claimed that it is “nearing completion”:
Here are a few images from inside the factory (via Tesla):
Previous reporting stated that Tesla aims to produce about 10 GWh of LFP battery cells per year at the new factory.
The cells are expected to be used in Tesla’s Megapack, produced in the US. Tesla currently has a capacity to produce 40 GWh of Megapacks annually at its factory in California. The company is also working on a new Megapack factory in Texas.
It’s nice to see this in the US. LFP was a US/Canada invention, with Arumugam Manthiram and John B. Goodenough doing much of the early work, and researchers in Quebec making several contributions to help with commercialization.
But China saw the potential early and invested heavily in volume manufacturing of LFP cells and it now dominates the market.
Tesla is now producing most of its vehicles with LFP cells and all its stationary energy storage products.
It makes sense to invest in your own production. However, Tesla is unlikely to catch up to BYD and CATL, which dominate LFP cell production.
The move will help Tesla avoid tariffs on a small percentage of its Megapacks produced in the US. Ford’s effort is more ambitious.
It’s worth noting that both Ford’s and Tesla’s LFP plants were planned before Trump’s tariffs, which have had limited success in bringing manufacturing back to the US.
