Which thesis makes more sense?ĪT&T looks like a much more promising investment after its recent divestments of WBD and DirecTV. It maintained its full-year capex target of $24 billion, which will be mostly spent on upgrading its 5G and fiber networks, as well as its target of $4 billion to $6 billion in transformation-related savings.

For the full year, it still expects its revenue to rise by the low single digits, and for its adjusted EPS to increase 0%-2%. The rest of AT&T's guidance remained unchanged. It also reiterated its full-year guidance for more than 6% growth in broadband revenues. may notice reduced speeds until next bill cycle due to data prioritization. During congestion, the small fraction of customers using >50GB/mo. As for its broadband business, AT&T Fiber gained 316,000 net adds during the quarter, representing the segment's tenth consecutive quarter of more than 200,000 net adds. Get endless talk, text, and high-speed data on our networkplus 10GB of LTE mobile hotspot data. The mobility segment's average revenue per user also increased both sequentially and year-over-year.Īs a result, AT&T boosted the full-year revenue forecast for its wireless service revenue - which accounted for 51% of the company's top line in the second quarter - from "3% or better" to 4.5%-5%. Its mobility segment gained 813,000 postpaid phone net adds during the quarter, which represented its strongest second quarter in over a decade. The results will be presented at the 256th National Meeting & Exposition of the American Chemical Society (ACS).Yet there were still plenty of reasons to like AT&T's report. “The battery would function as their armor, and that would lighten the average soldier by about 20 pounds,” says Veith. If the batteries increase in size, the team’s research could also benefit military personnel. A patent on this technique is currently in the works.ĭrone batteries are the researchers’ first application targets, with further goals to step into the automotive sphere. Veith and the research team bypass this issue by first placing the silica before adding the electrolyte and finally sealing the battery. However, this method called for significant changes to the current production process. Previous methods to reduce battery fires utilized a nonflammable, solid electrolyte. Transitioning to battery design, the solid particles took the form of spherical, 200-nanometer-diameter pieces of silica, which were suspended in the liquid electrolytes used in lithium-ion batteries. The ooblex mixture, for example, had a colloid of cornstarch particles suspended in water. This behavior is due to solid particles being suspended in a liquid, known as a colloid.
On a cookie tray, the mixture was fluid, however, the liquid transformed into a solid when the concoction was poked. After the applied pressure stopped, the mixture returned to its liquid form. The project’s initial breakthrough occurred when Veith and his kids were playing with ooblex, a mix of water and cornstarch. Hello wowiewowie, Thank you for visiting us on the Business Forum. If a battery is damaged during a collision, the solidification prevents the electrodes from touching each other, thus the threat of fire greatly reduces. There is a fradulent att mobility collections acct on my credit and I have never used att services.
This gives the electrolyte impact-resistant capabilities. The new approach, which mixes the electrolyte with an additive, creates a combination that solidifies when faced with pressure. “In a lithium-ion battery, a thin piece of plastic separates the two electrodes,” says Gabriel Veith, Ph.D., Oak Ridge National Laboratory, and the project’s principal investigator “If the battery is damaged and the plastic layer fails, the electrodes can come into contact and cause the battery’s liquid electrolyte to catch fire.” Lithium-ion batteries are known for catching fire when damaged, which is a concerning fact considering their prevalence in consumer electronics.Ī research team from Oak Ridge National Laboratory and the University of Rochester aims to remedy this issue by designing a battery based on liquids that solidify on impact.
