The C4V Battery – Solid-State in Production?

Dean Sigler Batteries, Electric Aircraft Components, Electric Aircraft Materials, Sustainable Aviation 0 Comments

Jeffrey Engler of Wright Electric posted an item about Charge CCCV, LLC (C4V) which “demonstrated a prototype of its new Solid State Battery (SSB) at the NY BEST 2018 Fall Conference in New York.  The Company’s SSB solution delivers higher performance, higher density, lower cost batteries that promise to require significantly less charging time than others.”  The startup announced a 380 Watt-hour-per-kilogram battery already in production.  Since your editor tends to become a bit snarky about the usual two-to-five-year period of anticipation before these numbers become reality, he rushed to check out the claims. Plausible Numbers, but Uncertain Time Frame The firm’s numbers are not wildly excessive, and they seem to be getting funding and finding partnerships with established companies.  …

Carbon Fiber and the Grand Unified Airplane

Your editor has long held the belief that we are on the threshold of creating a Grand Unified Airplane, a craft that would draw all its energy from solar cells, the flexing of its wings, the air passing over its form, and the very act of flight itself.  It seems to become less of a science fiction ideal and more of real-world possibility every day.  Carbon fiber could be part of that possibility. What if your airplane were its own battery?  Think of the weight savings and potential endurance and range.  Your editor became fascinated with 2010 research done by Dr. Emile Greenhalgh of Imperial University in London, who developed a structural sandwich with carbon fiber outer layers and a …

Promising 3D Printed Microlattice Battery

Dean Sigler Batteries, Electric Aircraft Components, Electric Aircraft Materials, Sustainable Aviation 0 Comments

The three biggest words in battery structures are “Area, Area, Area.”  The more anode and cathode area a battery can expose to the electrolyte that carries ions and electrons between the positive and negative ends of the battery, the better.  Most battery configurations, according to researchers at Carnegie Mellon University and Missouri University of Science and Technology, block a great deal of interaction between these elements.  Their solution is to go porous in a microlattice battery, thanks to 3D printing. Electrodes present some surface area to the electrolyte, which can only interact with the surface area presented.  Rahul Panat at Carnegie Mellon and Jonghyun Park at Missouri S & T have created a cube-shaped battery composed of microlattice electrodes which …

Wireless Charging for Drones

In its introduction, Global Energy Transmission Corporation (GET) promises virtually indefinite flight for multi-rotor aircraft.  “GET re-invents [the] commercial drone industry providing [a] technical solution to power drones in 24×7 mode around dedicated area[s]. An electrically powered drone can recharge and fly indefinitely via efficient safe high power in-flight rapid recharging in a GET power hotspot. The company’s distance wireless charging technologies uniquely enable drone delivery and many other industrial applications.and many other industrial applications.”  This wireless charging concept goes back a long way. Tesla’s Dream In the film The Prestige, key parts center on visits to Nikola Tesla’s laboratory in upstate New York, where the tower that dominates the grounds was one of his dreams.  Although never completed in …

Liquid Batteries for Aircraft?

NASA is investigating “the integration of nanoelectrofuel (NEF) flow batteries with rim-driven electric motors to produce a safe, clean and quiet propulsion system for aircraft,” according to Aviation Week. That is the promise of an early-stage rechargeable liquid battery technology under investigation by NASA. The agency is researching the integration of NEF flow batteries with rim-driven electric motors to produce a safe, clean and quiet propulsion system for aircraft.  The rim-driven motors are used on boats as thrusters, and may have applications on small unmanned aircraft, although researchers have seen disappointing results so far. Tying these motors to more promising research into” non-explosive energy storage technology” is part of NASA Armstrong Flight Research Center’s Aqueous Quick-Charging Battery Integration for Flight …

Coots and e-Gulls at Oshkosh

Lead image shows Mark Beierle in the Soaring Gull of his design with which he accompanied Richard Steeves to Oshkosh. As many readers know, Richard Steeves, a physician and teacher at the University of Wisconsin – Madison is also a builder and long-time advocate for an amphibious aircraft called the Coot.  He publishes the Coot Builders Newsletter and stages a recurring AirVenture event, a yearly get-together of fellow Coot builders.  Recently, he got into electric aviation and has built and flies Bravo, an e-Gull designed by Mark Beierle.  Richard’s newsletter now features articles about amphibians and electric flight. Mark showed up at Richard’s hangar at the Sauk Prairie Airport, a lovely stretch of green bordered by hangars and bisected by …

Flow Batteries Aging Well

As previously noted in the blog, the Tissandier Brothers flew their Siemens-powered electric airship in 1883 using a flow battery of their own design for energy storage.  This technology gets a lot of attention for grid-based energy storage, but might have use in more mobile applications.  Nano Flow Cell Technologies in Switzerland, for instance, used different salt waters to power their Quant and Quantino automobiles. Howard Handelman, a regular reader of the blog, shared the following two researches into modernizing flow cells.  Stanford and Harvard researchers both cooked up different ingredients than one would normally find in a flow battery.  Both groups achieved better than average performance and longevity. Stanford’s Liquid Metal Approach Stanford’s battery uses liquid metal that more …

Peter Sripol Groundloops – But Check Out Those Motors!

Peter Sripol is a high-energy model-airplane tester who put a twin-motor electric biplane together out of Home Depot/Lowes parts and flew it successfully.  That was a back of the envelope design that flew nonetheless. Peter did something a little more professional for his second go-round, crafting some professional-looking drawings.  Don’t look for any drawings for the earlier machine, he cautions, explaining there are none  He also wanted a pair of larger, slower turning propellers to move a large volume of air more slowly than the Rotomax 150s installed on the biplane.  He notes he’s looking for a lower kV (turns per Volt input). Peter works with Flite Test, a model airplane outfit seemingly willing to try anything.  That includes the …

From the CRADLE to the Breakthrough  Battery

Dean Sigler Batteries, Electric Aircraft Components, Electric Aircraft Materials, Sustainable Aviation 0 Comments

Hyundai, the Korean carmaker turning increasingly to electric vehicles, has teamed with Ionic Materials, a Massachusetts-based battery developer to work on an innovative solid-state battery.  Ionic’s solid polymer electrolyte technology promised to improve battery safety and performance.  Liquid electrolytes are often blamed for disastrous battery fires, so the search for a solid-state alternative is one way to counter the problem. Hyundai’s CRADLE (Center for Robotic-Augmented Design in Living Experiences), “corporate venturing and open innovation business,” is investing in Ionic to gain access to the company’s technology, which also supports lithium-ion cells with no cobalt in their cathodes.  Reducing or eliminating cobalt in their batteries may be a major incentive for Hyundai.  Forbes reports, “Carmakers, such as Germany’s BMW, and electronic gadget …

Battery Options for Range and Longevity

Two varying approaches to battery development may hold clues to future directions for energy storage.  At the same time, their announcements, promising as they seem, reinforce our cautious attitudes toward how battery performance numbers are presented. PNNL Attacks the Electrolyte Issue According to Green Optimistic, “Researchers from the Pacific Northwest National Laboratory (PNNL) have developed a new formula for battery’s electrolyte solution to enhance its performance unprecedentedly in terms of its service life and storage capacity or an electric vehicle’s range.” The video gives an overview of what it takes to make a battery and hints at the reasons battery research takes so long to give up improved energy storage devices. Unprecedented the development may be, and the promise of …
