Scientists develop lithium-air battery design to increase energy storage

Scientists develop lithium-air battery design to increase energy storage

Scientists at the Illinois Institute of Technology and Argonne National Laboratory have developed a new approach based on a four-electron reaction process to produce lithium-air batteries that have higher energy density than current Li-ion technology.

So far, lithium-air battery demonstrations have been limited to only one- or two-electron reaction processes, resulting in the formation of lithium superoxide (LiO2) or lithium peroxide (Li2O2), respectively. The reaction in the four-electron reaction process relies on the use of a solid-state electrolyte and a catalyst, trimolybdenum phosphide (Mo3P). This is important, as reactions involving more electrons create more energy storage.

The scientists have created a lithium-air battery cell consisting of a lithium metal anode, air-based cathode and solid ceramic polymer electrolyte (CPE). Upon discharge and charge, lithium ions (Li+) go from anode to cathode, then back.

Unlike traditional lithium-ion batteries that use liquid electrolytes, the new battery uses a solid composite electrolyte based on nanoparticles containing lithium. The electrolyte is embedded in a matrix made of a special material called a ceramic-polyethylene oxide polymer.  Researchers showed that the battery can be recharged for at least 1,000 charge-discharge cycles. With further development, the design could reach a specific energy of 1,200 Wh/kg.

The composite electrolyte embedded with Li10GeP2S12 nanoparticles exhibits high ionic conductivity and stability and high cycle stability. Low-dose cryogenic transmission electron microscopy carried out at the Center for Nanoscale Materials, a DOE Office of Science user facility, confirms the reaction mechanism, which favors four-electron reaction chemistry by reversible formation and decomposition of Li2O as the main product.

The research found that the battery is rechargeable for at least 1,000 cycles at room temperature, which the scientists say represents significant progress toward practical applications of lithium-air batteries.

Using a solid-state electrolyte instead of a liquid electrolyte would also reduce concerns around fire safety. The discovery also opens up novel ideas for designing lithium-based battery chemistry that works at room temperature. These future designs could achieve even greater energy storage, according to the researchers.

Renesas introduces high-efficiency 650 V GaN FETs targeting EV charging and power electronics

Renesas Electronics has announced three new 650 V high-voltage gallium nitride (GaN) field-effect transistors (FETs) developed specifically for e-mobility charging stations, AI data center and server power supplies (including 800 V HVDC architectures) and battery energy storage. The fourth-generation plus (Gen IV Plus) devices—named TP65H030G4PRS, TP65H030G4PWS, and TP65H030G4PQS—are based on the proven SuperGaN platform acquired through Renesas’ 2024 takeover of Transphorm, utilizing depletion-mode (d-mode), normally-off GaN technology.

These Gen IV Plus GaN components offer lower switching losses, smaller size, and increased thermal efficiency compared to silicon and silicon carbide (SiC) counterparts. Specifically, the devices use a die 14 percent smaller than the previous generation, achieving a reduced on-resistance (R_DS(on)) of 30 milliohms (mΩ)—a 14 percent improvement—and offering a 20 percent improvement in the on-resistance output-capacitance product figure of merit (FOM). The smaller die size directly reduces output capacitance, enhancing efficiency and enabling higher power density, ultimately resulting in lower overall system costs.

Available in TOLT, TO-247, and TOLL packaging configurations, these GaN FETs give engineers broad flexibility for optimizing thermal management and PCB layouts in power systems ranging from one to 10 kW, with higher ratings achievable through paralleling configurations. Surface-mount options (TOLL and TOLT) provide bottom- or top-side thermal conduction paths, optimizing cooling and aiding simpler device paralleling. The traditional TO-247 package offers enhanced thermal dissipation suitable for applications requiring higher power handling.

Renesas emphasizes the devices’ silicon-compatible gate drive inputs, allowing use of standard silicon MOSFET gate drivers rather than specialized drivers typically required by enhancement-mode (e-mode) GaN alternatives. This architecture lowers barriers to adoption, simplifies integration, and reduces complexity for engineers aiming to transition from silicon to GaN-based designs.

“The rollout of Gen IV Plus GaN devices marks the first major new product milestone since Renesas’ acquisition of Transphorm last year,” said Primit Parikh, Vice President of the GaN Business Division at Renesas. “Future versions will combine the field-proven SuperGaN technology with our drivers and controllers to deliver complete power solutions. Whether used as standalone FETs or integrated into complete system solution designs with Renesas controllers or drivers, these devices will provide a clear path to designing products with higher power density, reduced footprint and better efficiency at a lower total system cost.”

The new Gen IV Plus GaN FETs and associated 4.2 kW Totem-Pole PFC GaN Evaluation Platform (RDTTP4200W066A-KIT) are currently available for sampling and prototyping.

LG Energy Solution, Tesla build LFP battery plants in the US

Lithium iron phosphate (LFP) batteries are all the rage these days. Although they offer lower energy density than batteries based on NMC (lithium nickel manganese cobalt) chemistries, they tend to be cheaper, and their ingredients are more readily available, less toxic and less controversial. Automakers including Ford and Stellantis are steadily building production capacity for LFP cells in the US and Europe (generally in cooperation with Asian battery-makers).

LG Energy Solution has unveiled a new facility in Holland, Michigan to produce LFP batteries at scale. The company established its first gigawatt-size battery plant in Holland in 2012.

The new plant is producing LFP batteries specifically for energy storage systems (ESS)—stationary batteries, not battery packs for EVs. (LFP cells offer long cycle life, making them especially suitable for ESS applications.) Average annual production capacity is expected to be 16.5 GWh. The $1.4-billion plant is expected to employ up to 1,700 people

“We have a solution where we can provide energy storage in any location where the energy is being produced and where it can be used in an efficient way to optimize the grid,” said Bob Lee, President of North America for LG Energy Solution, adding that the company is prepared to more than double its current capacity if demand grows.

The Holland facility will also produce NMC cells and modules for the Ford Mustang Mach-E, which LG Energy Solution previously produced in Poland.

LG Energy Solution currently owns four battery manufacturing facilities in the US—two in Holland, one in Lansing, and one in Queen Creek, Arizona.

CleanTechnica’s Paul Fosse got a chance to tour the new plant and observe the manufacturing process: creating slurry, coating foil, stacking cells with safety-reinforced separators, sealing in aluminum pouches and injecting electrolyte. The process is now operational on two lines, and a third is expected to go into service by the end of the year.

Meanwhile, Tesla says it is “nearing completion” of its own new LFP battery manufacturing facility, near its Gigafactory Nevada.

While Ford entered a technology licensing agreement with Chinese battery giant CATL for its Michigan battery plant, Tesla purchased manufacturing equipment from the company, a strategy that has allowed Tesla to avoid the political complications that have plagued Ford’s CATL partnership.

Battery Technology’s Michael C. Anderson says video footage released by Tesla appears to confirm that the company has implemented a wet coating process for electrode manufacturing at the Nevada facility. This matches CATL’s predominant manufacturing methods for LFP, but contrasts with the dry coating process that Tesla is developing for its 4680 cells in Texas.

Tesla’s new facility is expected to start with approximately 10 GWh of annual production capacity. The initial output is expected to be used in stationary storage products such as Tesla’s Powerwall and Megapack rather than in EVs—the same approach taken by LG Energy Solution with its new Michigan LFP facility.

Tesla doesn’t catch fire after falling off a cliff (video)

A general perception about Teslas and electric vehicles is that their large battery packs are prone to catching fire in accidental scenarios.

However, in many Tesla vehicle accidents, a very minimal number of incidents were reported to have caught fire. The reasons for these fires may be different than the battery pack’s high voltage sparks.

For an ultimate validation of Tesla battery pack fires in case of an accident, YouTuber Danny Duncan performed a unique test. The influencer sacrificed his previous-generation Tesla Model 3 and pushed it off a high cliff.

This is one of the most brutal forms of putting a vehicle through a safety test, beyond the conventional crash safety testing.

Interestingly and historically, Tesla electric vehicles tested for crash safety by NHTSA, Euro NCAP, and ANCAP have never caught fire during testing. However, pushing the vehicle off a cliff gives us further proof of whether Tesla battery pack fires are real or a myth.

So, Danny and his friends arranged for a Tesla Model 3 to be launched off a cliff to see if it catches fire or not. In the middle of the long vlog by the YouTuber, he also tested Tesla’s body and glass by hitting them with tin cans using a hydraulic pressure gun.

The Tesla glass survived this intense hit test. The can hitting it at high velocity didn’t pass through the window of the Tesla Model 3, while the ICE vehicle’s window broke, and the can entered the car’s cabin.


The test result must have come as a surprise to Tesla critics. The Tesla vehicle did not catch fire after falling off the cliff. The vehicle was destroyed, but it busted a myth of Tesla battery fires in accidents.

A previous generation of the older Tesla Model 3 was used in this test. The latest generation Model 3 Highland and the entire new lineup is much better than the legacy generation in terms of safety features and crashworthiness.

So, if an older Tesla doesn’t catch fire after dropping off a cliff several meters down, the newer generation is expected to perform even better. A Cybertruck even sustained a bomb blast at the Trump Hotel earlier this year, and it didn’t catch fire.

So far, the video has received 2.3 million views on YouTube and 1.3 million views on Musk’s X (Twitter) and generating heaps of discussion about Tesla vehicle safety.
