With the rise of electric vehicles, every ounce of lithium in lithium-ion batteries is precious. A team of scientists from Rice University has figured out a way to retrieve as much as 50 percent of the material in used battery cathodes in as little as 30 seconds.

Researchers at Rice University’s Nanomaterials Laboratory led by Department of Materials Science and NanoEngineering Chair Pulickel Ajayan released the findings a new study published in Advanced Functional Materials. Their work shows that the process overcomes a “bottleneck” in lithium-ion battery recycling technology. The researchers described a “rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent,” according to a news release.

Past recycling methods have involved harsh acids, and alternative eco-friendly solvents like deep eutectic solvents (DESs) at times have not been as efficient and economically viable. Current recycling methods recover less than 5 percent of lithium, which is due to contamination and loss during the process.

In order to leach other metals like cobalt or nickel, both the choline chloride and the ethylene glycol have to be involved in the process, according to the researchers at Rice. The researchers submerged the battery waste material in the solvent and blasted it with microwave radiation since they knew that of the two substances only choline chloride is good at absorbing microwaves.

Microwave-assisted heating can achieve similar efficiencies like traditional oil bath heating almost 100 times faster. Using the microwave-based process, Rice found that it took 15 minutes to leach 87 percent of the lithium, which differs from the 12 hours needed to obtain the same recovery rate via oil bath heating.

“This method not only enhances the recovery rate but also minimizes environmental impact, which makes it a promising step toward deploying DES-based recycling systems at scale for selective metal recovery,” Ajayan says in the release.

Due to rise in EV production, the lithium-ion battery global market is expected to grow by over 23 percent in the next eight years, and was previously valued at over $65 billion in 2023.

“We’ve seen a colossal growth in LIB use in recent years, which inevitably raises concerns as to the availability of critical metals like lithium, cobalt and nickel that are used in the cathodes,” the study's co-author, Sohini Bhattacharyya, adds. “It’s therefore really important to recycle spent LIBs to recover these metals.”

Houstonians David Downing and Jose Hernandez were tired of having such limited options when it came to finding healthy dessert alternatives. So, they founded ChipMonk Baking, a local, mail-order bakery that creates treats using monk fruit and allulose, a low-calorie (0.4 calories per gram) rare sugar that's found naturally in foods such as raisins, dried figs, and kiwi. Hernandez began developing ChipMonk's recipes to satisfy his taste for cookies after being diagnosed with type-2 diabetes.

An online business, ChipMonk offers every snacks from cookies and bites to mixes and sweeteners. There are also a few bundles to choose from as well as a free, downloadable holiday cookbook

Skin-healthy athletic wear from Élastique

Moms know how to make the most of their time, and that's exactly how Emeline Kuhner-Stout came across the idea for Élastique Athletics, a clothing line that promotes skin health and reduces cellulite.

"We did some research, and found that the best way to improve the appearance of your skin and move those fluids — because the cause [of cellulite] is really about those fluids that get trapped under your skin and cause a lot more negative effects other than skin appearance," Kuhner-Stout previously told InnovationMap.

She learned that exercise is the best move for improving lymphatic drainage, and another option is to do it manually through massaging and with compression. After around five years of research and development, Kuhner-Stout was able to release her first product for Élastique Athletics — a pair of leggings that have MicroPerle™ micro-massage beads in the compression leggings to massage the skin when worn.

Now, Élastique has three "wellnesswear" products available online.

Support local with Sesh Coworking

Sesh Coworking is a space founded for women, by women, and that focus extends to the company's in-store and online market. Located in Montrose, Sesh opened its doors in February and was founded by Maggie Segrich and Meredith Wheeler to fill a need in the coworking sector.

"We as women show up in our work lives as a whole person. We don't compartmentalize and forget about all the other things happening in our lives," Wheeler previously told InnovationMap. "We wanted a space that reflected that and embraced it."

While the market supports local female-owned business year round, Sesh has some special items for the holidays. The company has produced a 2020 Holiday Haute List to help users find the perfect gift as well as some gift bundles for the working women of the world. These sets and more are available on Sesh's online store.

Stylish sanitizers from Cobalt

This year's pandemic inspired new products and companies aplenty, and one of them here in Houston is Cobalt founded by Houstonians Molly Voorhees and Christina Milligan. Their hand sanitizing and surface cleaning products blend the importance of cleanliness and safety with the added value of accessibility and a refined appearance.

As working parents of young children, the two women wanted to create a line of sanitizing products that boosted their confidence in the safety of their environments amid a pandemic and that they'd be proud to pull out of their purse on short notice.

"Cleaning products are in your bathroom or are in an ugly looking bottle or the back of our restaurant in massive chemical containers. There is really nothing for the on-the-go market," Voorhees says.

The company sells six FDA-approved sanitizers, sprays, keychains, and to-go kits that eliminate 99.9 percent of bacteria and viruses in easy to access, personal-sized, contemporary bottles, ranging from $14 to $30. The products are designed to be free of harsh, alcoholic odors and come in scents like peppermint and bubble gum.

The gift set, which is available online for $50, includes a bottle of hand sanitizer, surface spray, and mask refresher.

Humidity-conscious women's workwear from Cotidie

Other than during Houston's brief winter, rocking a professional wardrobe is tough in humidity that is so iconic to Houston. Local entrepreneur Kristina Haag founded Cotidié to design clothes with this struggle in mind.

"With Cotidié, it is all about the functionality of the clothing," Haag previously told InnovationMap. "It is more traditional items, but the use of technical fabrics is our differentiating factor."

The online retailer, which launched in June 2019, offers dresses, jackets, pants, skirts, and tops, ranging between $60 and $200 in price. The fabrics, sourced from Italy and Taiwan, provide breathable comfort, along with an elastic, structured fit for a more tailored look. All items are moisture wicking and machine washable.

"Everything we use on the line is athletic technical fabric that you would typically find in workout attire, but I've repurposed these fabrics to use in a contemporary womenswear line," Haag tells InnovationMap. "I wanted to create a more foundational capsule clothing collection that women can draw their own inspiration from."

The full collection is available online, as are gift cards.

Houston entrepreneurs launch design-focused sanitizing operation

happy hands

Houstonians Molly Voorhees and Christina Milligan have officially launched a line of hand sanitizing and surface cleaning products that blend the importance of cleanliness and safety with the added value of accessibility and a refined appearance.

The products make up the entrepreneurs' new brand, Cobalt, that Voorhees, president of Beck's Prime, and Milligan, an organizing and style expert, first conceptualized in March. As working parents of young children, the two women wanted to create a line of sanitizing products that boosted their confidence in the safety of their environments amid a pandemic and that they'd be proud to pull out of their purse on short notice.

"Cleaning products are in your bathroom or are in an ugly looking bottle or the back of our restaurant in massive chemical containers. There is really nothing for the on-the-go market," Voorhees says.

Too, the women didn't want to stop at hand sanitizer. Instead, they sought to encourage and educate clientele on the importance of cleaning high-touch surfaces, like phones, steering wheels, sunglasses, and the likes.

"It really resonated with us that your hands are only as clean as the surfaces that you touch," Milligan says. "We wanted it to be very approachable and easy to understand and also discrete. We didn't want anyone to feel ashamed if they pulled out a bottle of Lysol on a table."

The result was six FDA-approved sanitizers, sprays, keychains, and to-go kits that eliminate 99.9 percent of bacteria and viruses in easy to access, personal-sized, contemporary bottles, ranging from $14 to $30. The products are designed to be free of harsh, alcoholic odors and come in scents like peppermint and bubble gum.

Each item in the line boasts sleek, trendy designs in a cool blue hue. And while they look quite polished today, bringing the line to launch started off as a somewhat messy process.

"We kinda thought it would be easy. We would just put cleaner in a 4-ounce bottle and that would be fine," Milligan says.

But due to the high demand for chemical products in the pandemic and the way that industrial filling lines are set up, producing cleaning products in personal-sized bottles proved difficult. The women, who became known as the "the girls who want to put cleaner in their purse," were initially met with a resounding "no" from large chemical corporations.

However, by the summer the duo was able to make more headway. They were nearing production with a chemical partner when they learned of a local business who could produce their product by hand all within the Bayou City.

"It turned out through a connection we were making with labels that we discovered [William Price Distilling Company] that was right in our backyard in Houston that was newly filling bottles," Milligan says. "They were employing out of work restaurant staff. Molly and I both felt really strongly about that."

Voorhees and Milligan quickly partnered up with the Garden Oaks-Oak Forest distillery and have since produced roughly 2,500 units of their various products.

In fact, the line is decidedly Houston-based. In addition to William Price, Cobalt was also created with the help of Houston Labels for design. Deutser helped the team from a business management perspective. And the custom scents were developed by Clarity Fragrance near Memorial City.

As of press time, the products are available for purchase online and in area boutiques, including Emerson Sloan, Lexington Boutique, Zadok Jewelers, Therapy Hair Studio, and The Chocolate Bar. They aim to expand to more stores and markets and adapt the line based on demand.

"We feel so fortunate that we have a variety of products," Voorhees says. "It's always my belief that the consumer will tell you what they want and you go in that direction."

Houston femtech co. debuts first holistic wellness suite following rebrand

work perks

Houston-based femtech company Work&, previously Work&Mother, debuted new lactation suites and its first employee wellness space at MetroNational’s Memorial City Plazas this month.

The 1,457-square-foot Work& space features three lactation rooms and five wellness suites, the latter of which are intended to offer employees a private space and time for telehealth appointments, meditation, prayer, and other needs. The hybrid space, designed by Houston-based Inventure, represents Work&'s shift to offer an array of holistic health and wellness solutions to landlords for tenants.

Work& rebranded from Work&Mother earlier this year. The company was previously focused on outfitting commercial buildings with lactation accommodations for working parents, equipped with a hospital-grade pump, milk storage bags, sanitizing wipes, and other supplies. While Work& will still offer these services through its Work&Mother branch, the addition of its Work&Wellbeing arm allows the company to also "address the broader wellness needs of all employees," according to an announcement made on LinkedIn.

"We are thrilled to bring Work&Mother and Work&Wellbeing to The Plazas," Jules Lairson, co-founder and COO of Work&, said in a news release. “This partnership brings every stakeholder together – employees, employers and landlords all benefit from this kind of forward-thinking tenant experience. We are excited to launch our Work&Wellbeing concept with MetroNational to ensure that all employees have their wellness needs met with private, clean, quiet spaces for use during the workday.”

The new space is available to all tenants across Memorial City Plazas, comprised of three office towers totaling 1 million square feet of Class A office space. In addition to the lactation and wellness suites, the space also features custom banquettes, private lounge seating and phone booths.

“As a family-owned and operated company, MetroNational is deeply committed to fostering a workplace that supports both productivity and the well-being of all our tenants,” Anne Marie Ratliff, vice president of asset management for MetroNational, added in the release. “Partnering with Work& reinforces this commitment, enhancing our workplace experience and setting a new standard for tenant amenities.”

Work& has five Houston locations and several others in major metros, including New York, Austin, D.C., Boston, Chicago, San Francisco, and Miami. According to its website, the company will also introduce a Work&Wellbeing suite in New York.
