In North Carolina, a Battery Revolution May Be Brewing

(DGIwire) – In 1903, North Carolina hosted the Wright Brothers’ first-ever airplane flight. More than a century later, the state is still the home of technical innovation. One manifestation is the “Joules Accelerator,” a Charlotte, North Carolina-based program initiated in 2013 and dedicated to advancing the city’s reputation as a hub for energy-focused companies. The […]

Shaping the Future of Energy Storage

(DGIwire) – Lithium-ion batteries are widely used in consumer electronics and electric vehicles (EVs) because they pack a powerful punch—with what’s called a “high energy density.” But they also contain highly flammable chemicals, called electrolytes, that can become unsafe if overcharged. While work is ongoing to address this problem, another solution has presented itself: supercapacitors, […]

Electric Vehicles: Only as Good as Their Batteries

(DGIwire) – Will battery electric vehicles (EVs) save the planet? If they succeed, it will certainly have a lot to do with the kind of batteries they utilize. One of the reason EVs improve on traditional cars is because the latter utilize lead-acid batteries, which—although relatively cheap and recyclable—exploit workers using unsafe methods to do […]

Japan Races to Embrace an Electric-Car Future

(DGIwire) – What is the biggest threat to traditional car manufacturers in Japan? As The New York Times recently reported, it is the advent of battery-powered electric vehicles. According to the Times, conventional auto part suppliers are nervous: they and the carmakers they work with provide one in 10 Japanese jobs and account for a […]

Professional Power Tool Users: Time to Look Beyond Lithium-Ion

(DGIwire) – Reliable power tools are crucial to maintaining the reputations of electrical, cable and telecom companies. However, as recently reported in Utility Products magazine, engineers and field technicians are bound by the technical limitations of Lithium-ion battery packs, which present a series of drawbacks. For example, if there has been insufficient time to recharge […]

Fidget Spinners in Flames: Mishaps Show Need for New Power Options

(DGIwire) – The last thing anyone wants from a fidget spinner is a third-degree burn. Unfortunately, the risk seems to be a real one. As recently reported in The Telegraph, multiple cases have arisen of Bluetooth fidget spinners—variants of the popular toys with inbuilt speakers that play music streamed from a mobile phone—were found to […]
