AMEYA360:How Smart 3D Electrodes Will Power Next-Gen Batteries

　　Addionics has developed a novel manufacturing process named smart 3D electrodes, which improves rechargeable batteries’ performance by redesigning their architecture. According to the company, the new technology enables higher capacity and safety, lower charging time and cost, and a longer lifetime.　　The company’s 3D fabrication process differs from currently used architectures in how the battery’s collector is made. Today, most collectors are made with 2D metal foils — a technology that has remained unchanged in the last 30 years.　　“While everyone is using conventional 2D 100% dense metal foils, at Addionics, we are replacing this component with a 3D metal structure that can load more active materials, increase the energy density, reduce the internal resistance, and provide better mechanical adhesion and thermal stability,” said Moshiel Biton, CEO of Addionics in an interview with EE Times.　　Addionics is an English company with subsidiaries in Israel, the United States, and Germany. After raising $40 million in funds to develop its smart 3D architecture, the company is moving towards manufacturing. The transition from R&D to production began with the opening of a new facility in Tel Aviv, the pilot line for producing the Smart 3D Electrodes components.

AMEYA360:AI Industry Responds to Call for Pause on AI Development

　　The AI industry has responded to an open letter from the Future of Life Institute signed by AI academics and key tech industry figures, which calls for a six-month pause on the training of AI systems more powerful than GPT-4. The letter was signed by AI experts including Turing Award winner Yoshua Bengio, UC Berkeley computer science professor Stuart Russell, Apple co-founder Steve Wozniak and Twitter CEO Elon Musk.　　“This pause should be public and verifiable, and include all key actors,” the letter says. “If such a pause cannot be enacted quickly, governments should step in and institute a moratorium.”　　Written in the shadow of recent hype about the capabilities of GPT-4–powered AI agents like OpenAI’s ChatGPT, concerns cited by the experts in the letter include AI “[flooding] information channels with propaganda and untruth,” “[automation] of all jobs, including the fulfilling ones,” and “[risking] loss of control of our civilization.”　　“Such decisions must not be delegated to unelected tech leaders,” the letter says. “Powerful AI systems should be developed only once we are confident that their effects will be positive and their risks will be manageable.”

AMEYA360:Surge Suppression Circuits

　　In the previous article we briefly explained surges that occur in gate-source voltages. From this article, AMEYA360 will address measures to deal with surge occurrences. We begin by presenting surge suppression circuits.　　Surge Suppression Circuits　　As explained in the previous article, positive surges in the gate-source voltage (VGS) occur on both switching and non-switching sides, but surges are especially problematic when they occur on the non-switching side (HS: high side) during LS (low side) turn-on (phenomena II). The waveform diagram on the right is the same as one presented in the previous article.　　The reason for this is that, because the switching side is already in the turned-on state, if a positive voltage surge on the non-switching side has exceeded the gate threshold voltage (VGS(th)) of the SiC MOSFET, simultaneous HS and LS turn-on occurs, and a shoot-through current flows.　　However, the transconductance of SiC MOSFETs is at least an order of magnitude lower than that of Si-based MOSFETs, and so sudden excessive shoot-through currents do not flow. Consequently, even if a shoot-through current had been flowing, cooling performance is sufficient, and if the Tj(max) of the MOSFET is not exceeded, there should essentially be no problems. Even so, shoot-through currents are factors directly detracting from the efficiency of the system as a whole, and cannot be called a desirable state of affairs. Hence a circuit should be added in order to suppress any voltage surges so that insofar as possible they do not exceed the VGS(th) of an SiC MOSFET.

AMEYA360:How ABB Is Getting Ahead of Network Outages

　　Issues tend to crop up at the worst possible time. Network engineers know this all too well. This is just one reason why it’s critical to have a reliable out-of-band management solution available when you experience a network outage.　　Network engineers already understand the many factors that could cause a disruption: Hardware failures cause 34%, human errors cause another 21.5%, and hacks or security breaches bring another 18.7%.　　Matt Witmer, Senior Principal Engineer, Opengear　　Regardless of an outage’s root cause, every minute of downtime is costly. A recent survey of global managers, directors, VPs and executives found the average amount lost due to network outages is roughly $13,000 per minute — and that’s just the financial element. Damage to a company’s reputation, stress put on IT professionals rushing to fix the problem, dissatisfied customers — and the corresponding fallout from each — all represent significant costs as well.　　Consider the case of ABB, a leading global industrial technology company with a comprehensive portfolio of products in the robotics and electronics spaces. ABB was recently looking for a reliable out-of-band solution to monitor and secure its network and the numerous AIoT devices connected to it. The modernization was much needed, as the company had previously relied on 56Kbps modems and analog telephone lines to provide 24/7 connectivity to multiple physical locations, including data centers, distribution centers, manufacturing facilities and sales offices. So, any disruption would result in lost business, service interruptions and poor customer service experiences.　　ABB’s U.S. network and voice services team was tasked with overseeing the upgrade, opting for Opengear solutions, starting with our ACM7000 Resilience Gateways. These products provide in-band and out-of-band access to AIoT devices. Providing secure, out-of-band remote access at edge locations, thanks to an embedded, global 4G-LTE cellular modem that provides an alternate path when the primary link is down, the gateways were deployed at different ABB facilities, with the 4-port versions going to manufacturing sites. Our eight-port gateways were placed at ABB’s distribution centers to ensure business continuity. Finally, for its data centers, ABB chose our 48-port CM7100 Console Server, which offers 16-96 serial console ports with simple straight-through cabling to Cisco-style serial consoles, ideal for large compute locations.　　Not long after a successful deployment of our advanced routers, modems and remote-management tools, ABB experienced a network outage during a standard data center migration from one circuit carrier to another. ABB’s IT team was able to quickly access the data center network with new, out-of-band management capabilities, keeping downtime to a minimum and keeping AIoT devices secure.　　Since the initial rollout, ABB has added more Opengear devices in its network. Today, the company has hundreds of them across two data centers, two distribution centers, plus its manufacturing sites and sales offices — all in the name of business continuity and AIoT device security.　　ABB is now able to remotely monitor, safeguard against and repair network outages when they occur. As a result, the company ensures its IoT devices are securely connected and minimizes costly downtime.
