UNIST team develops new electrolyte additive for high-capacity Li-ion batteries

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea say they have developed an electrolyte additive that enables a high-energy-density Li-ion battery to retain more than 80% of its initial capacity, even after hundreds of cycles. In a paper published in Nature Communications, the scientists reported that when the substance was… Read more »

EVs are for everybody—but how to get Republicans to buy them?

Here at Charged, our position has always been that EVs are for everybody, and we’ve watched in disappointment as e-mobility has become a political football. Many others agree, including some red-state policymakers who have supported pro-EV measures in their states. Mike Murphy is a veteran GOP political consultant who has advised John McCain, Arnold Schwarzenegger,… Read more »

Huber’s new Unimotive model range offers precise temperature control for battery and material tests

Temperature control is a critical factor during stress and load testing in the development of batteries, materials and other vehicle components. The heat transfer fluid (HTF) used in testing is often a water-ethylene glycol mixture. To address these applications, thermoregulation specialist Huber has expanded its portfolio to include temperature control systems designed and tested specifically… Read more »

V2G and V2B: What’s currently operational and what’s still years away

Buses, especially school buses, represent a perfect use case for bidirectional charging. When the buses sit idle, they can earn money by providing demand response (DR) services for the local utility. This is one of the services that fleet charging specialist AMPLY Power provides, and as CEO Vic Shao told Charged in a recent interview,… Read more »

AMPLY Power offers EV fleets guaranteed uptime and zero charging challenges

AMPLY Power says its charging as a service model provides 99.9% uptime, critical to scaling EV deployments Fleet charging management may not be the most glamorous segment of the EV industry, but it is emerging as an extremely important component of the future EV ecosystem. As commercial fleets electrify, they are finding that they need… Read more »

Tesla to open Supercharger network to other automakers in Europe next year

Back in 2012, when Tesla introduced Model S, public chargers were almost nonexistent. Electric road trips were impractical, and the paucity of infrastructure was a major consumer objection to buying an EV (it still is). Frustrated with the slow pace of development of an EV fast charging standard, Tesla rolled out its own, and the… Read more »

New research suggests fluorine-based electrolyte enhances lithium metal battery stability

Scientists at the Ulsan National Institute for Science and Technology (UNIST), led by Professors Nam-Soon Choi and Sang Kyu Kwak, have developed a fluorine-based electrolyte for lithium metal batteries with Ni-rich NCM cathodes. According to their paper, published in Nano Energy, the electrolyte evenly formed a protective film on the negative and positive electrodes, increasing… Read more »

Unions fear electrification will vaporize their jobs

As the legacy automakers finally begin to get serious about electrification, it’s becoming increasingly clear that the accelerating transition will result in a major restructuring of the industry, which seems likely to include substantial job losses. As a recent Bloomberg article reports, fear of the electric future is an underlying reason for the United Auto… Read more »

2019 Hyundai Kona Electric: A viable EV competitor for the average car buyer

As a company, Hyundai often sets goals that slightly exceed those set by competing automakers. The engineers who designed the Ioniq Hybrid and Plug-In hatchbacks were told that the new vehicles had to beat the fuel-efficiency ratings of the Prius hybrid and Prius Prime plug-in hybrid. So it is with the Hyundai Kona Electric. We… Read more »
