UL Solutions Takes Aim at Lithium-Ion Battery Fire Risks with Innovative New Certification Programs for Battery Containment Enclosures and Micromobility Charging Equipment
Safety-certified battery containment enclosures are growing in popularity for use with e-bikes and other micromobility products, and are supported by fire departments, including the Fire Department of the City of New York (FDNY), for their ability to contain fire and other hazards associated with thermal runaway. UL Solutions also launched services for micromobility charging equipment that can further help mitigate safety risks.
Battery containment enclosures often resemble cabinets and are designed with safety features to contain battery thermal runaway fires and gases. They can be used to store and charge batteries, such as e-bike or power tool batteries, and help protect people around them if a thermal runaway event or battery fire occurs despite following proper battery maintenance and usage instructions from the manufacturer.
'The use of e-bikes is on the rise, and new products enter the market daily that tap the convenience and sustainability of batteries,' said Dr. Robert Slone, senior vice president and chief scientist at UL Solutions. 'Our new battery containment enclosure and micromobility charging equipment engineering evaluation, testing and certification services can help reduce the risks associated with the storage and charging of lithium-ion batteries and devices.'
UL Solutions conducts engineering evaluations and tests battery containment enclosures per UL 1487, the Standard for Battery Containment Enclosures, a binational Standard for the United States and Canada. The FDNY Hazmat Command played an integral role in crafting this document.
'It's really important to have third-party experts test and certify battery containment enclosures and micromobility charging equipment to make sure they meet safety standards,' said Chief of Fire Prevention Thomas Currao, FDNY. 'For battery enclosures especially, this kind of testing shows they can contain dangerous situations like thermal runaway, which will help stop fires or explosions from spreading.'
These tests evaluate a battery containment enclosure's ability to withstand battery thermal runaway events, including fire, explosion and shrapnel. Thermal runaway occurs when the lithium-ion battery enters an uncontrollable self-heating state that can produce fire, flammable and toxic smoke, and extremely high temperatures while ejecting harmful particulates.
'That kind of protection matters, whether it's in an apartment building, office or industrial space,' Currao added. 'Choosing certified equipment means we're taking smart steps to prevent battery hazards and make our city safer for the public and for our members.'
UL Solutions evaluates and tests micromobility charging equipment per UL 4900, the Standard for Micromobility Charging Equipment, which is also a binational Standard for the United States and Canada. This Standard addresses the electric shock and fire risks of the charging infrastructure.

Union Pacific Celebrates its 163 rd Birthday with New Commemorative No. 1616 Lincoln Locomotive in President Lincoln's Hometown
SPRINGFIELD, Ill.--(BUSINESS WIRE)--Union Pacific Railroad celebrated its 163 rd birthday today in the hometown of its famed founder – President Abraham Lincoln – with the help of numerous dignitaries and its newest commemorative locomotive that honors Lincoln's role in laying the foundation for America's best-in-the-world freight rail system. 'We think Lincoln would have been proud of the vital role railroads serve today in delivering the goods and products essential for everyday life in America,' said Liisa Stark, Vice President - Public Affairs for Union Pacific Railroad. Share The event was sponsored by Union Pacific, the Lincoln Presidential Foundation, Looking for Lincoln and Hanson Professional Services. Special guests at the event included Springfield Mayor Misty Buscher, Illinois Railroad Association President Tim Butler, Lincoln Presidential Foundation President and CEO Erin Mast, National Park Service Superintendent Chris Collins, State Sen. Doris Turner, State Sen. Mike Coffey, Union Pacific Vice President – Public Affairs Liisa Stark and Union Pacific Senior Director – Public Affairs in Illinois Tom Evenson. Lincoln founded Union Pacific with the signing of the historic Pacific Railway Act on July 1, 1862, which authorized construction of the nation's first transcontinental railroad network. 'Union Pacific is incredibly proud of our heritage, and we are honored to share this special locomotive in the hometown of the man who brought our railroad to life and unleashed economic prosperity,' said Liisa Stark, vice president of Public Affairs for Union Pacific Railroad. 'We think Lincoln would have been proud of the vital role railroads serve today in delivering the goods and products essential for everyday life in America.' The Lincoln Locomotive, which serves as a traveling ambassador for Union Pacific, made its debut on April 30 in North Little Rock, where it was painted by Union Pacific employees. It is painted in a color scheme unique to Lincoln's era and serves as a nod to another famed locomotive - No. 119 – which was one of two locomotives present at the Golden Spike Ceremony in Promontory Summit, Utah, in 1869, which marked the completion of the nation's first transcontinental railroad. Springfield was also designated as an official Train Town USA community. The honor celebrates the towns and communities along Union Pacific's tracks, many of which exist because of the railroad. Just as they were more than 100 years ago, these communities remain vital to the railroad's success. 'It is an incredible honor for Springfield to host Union Pacific Railroad on this historic milestone and to welcome the Lincoln Locomotive to the hometown of our 16th president. Abraham Lincoln's vision helped unite a nation, and that legacy lives on through the railroads that continue to connect communities and drive economic progress. Being named a Train Town USA is a proud recognition of Springfield's enduring role in our nation's rail history,' said Springfield Mayor Misty Buscher. Railroads are at the heart of the U.S. economy and touch nearly every industry including vehicles, chemicals, energy, agriculture, metals, minerals, forest products, consumer goods and more. Union Pacific's more than 30,000 employees deliver essential items from lumber and drywall to build homes to corn and wheat to make bread and cereal.

Nasdaq tops NYSE in 2025 IPO race with $21.3 billion in listings
Nasdaq handily beat the New York Stock Exchange in stock market listings during the first half of 2025, buoyed by blockbuster initial public offerings of big names like CoreWeave CRWV.O and Chime CHYM.O and a jump in proceeds raised via special purpose acquisition companies. IPOs at Nasdaq NDAQ.O, including those of blank-check acquisition companies, raised about $21.3 billion during the first half, compared with $8.7 billion for flotations at the NYSE ICE.N, according to data from Dealogic. Excluding SPAC volumes, traditional IPOs on the Nasdaq raised roughly $9 billion from 79 deals, while 15 IPOs on NYSE raised about $7.8 billion. Last year during the same period, Nasdaq IPOs had raised about $6.1 billion, while shares worth $11.5 billion were sold from IPOs on NYSE. Stock market launches dropped off sharply during the April market selloff that was driven by erratic U.S. trade policy, but Wall Street has since recovered and companies are starting to rush back to seek listings. "We felt this year had an opportunity to be good - and then we had enormous volatility to start the year, so companies across the board had to go pencils down," Nasdaq President Nelson Griggs told Reuters. "Clearly now, with the market rebound we've had after a very strong May, companies are back having those discussions. If the next round (of companies) does well, I think you're going to really see some excitement for the fall," Griggs added. More financial markets: Stocks usually rise by 10% a year. Those days may be over. The Nasdaq Composite .IXIC and S&P 500 .SPX reached record closing highs on Monday, capping their best quarter in more than a year. With its first-half listings performance, Nasdaq maintained its stranglehold at the top of the rankings. The exchange operator has led the IPO rankings ahead of NYSE during the better part of the past decade, including the last six years, according to Dealogic. The market share battle between the two top U.S. exchanges and the improving outlook for stock market listings follows an arid spell for capital markets that lasted for more than two years. Several big names, including medical supply giant Medline and design software maker Figma are gearing up for IPOs later this year. Liquefied natural gas exporter Venture Global's VG.N $1.75 billion share sale, CoreWeave's $1.5 billion raise, and cybersecurity firm SailPoint's SAIL.O $1.38 billion offering ranked as the biggest U.S. IPOs during the first half. "The largest IPO YTD is listed on the NYSE. We anticipate that issuance for the remainder of the year will continue to be active," NYSE Global Head of Capital Markets Michael Harris said. High-profile switches Both exchanges have been beneficiaries of large corporations transferring listings from one venue to the other. This year, Nasdaq has received a boost from high-profile switches including those of Kleenex tissue maker Kimberly-Clark KMB.O and content and technology company Thomson Reuters the parent company of Reuters News. Nasdaq said 10 companies with a combined market value of $271.4 billion have switched from the NYSE this year, the best first-half performance for the exchange operator since it started tracking the data from 2006. NYSE was buoyed by transfers from five companies including financial services firm Virtu VIRT.N, CSW Industrials CSW.N, and building products distributor QXO QXO.N in the first half. Some companies that transferred from NYSE to Nasdaq this year cited the attractiveness of the Nasdaq-100 index .NDX - which includes 100 of the most valuable non-financial companies listed on the Nasdaq, including the likes of Nvidia NVDA.O and Apple AAPL.O - as being a key driver for the decision to switch. The Nasdaq 100 has risen nearly 8% this year, compared to the S&P 500 .SPX, which has climbed about 5.5% year-to-date. "We realized very quickly that Nasdaq had something that was very compelling - if you are in the Nasdaq and you meet the threshold for the market cap, you can be part of the Nasdaq-100, a great index to be a member of," said Juan Pelaez, vice-president of investor relations at chemicals company Linde LIN.O, which switched to Nasdaq in 2023. The rivalry between Nasdaq and NYSE has played a big role in making U.S. capital markets more attractive for investors, compared to other markets like Hong Kong and London, which currently have only one venue for flotations, according to experts.
