Samsung researchers describe all-solid-state battery with silver-carbon composite layer
Researchers from the Samsung Advanced Institute of Technology (SAIT) and the Samsung R&D Institute Japan (SRJ) have published a study on high-performance, long-lasting all-solid-state batteries in the journal Nature Energy. Compared to lithium-ion batteries, which employ volatile liquid electrolytes, all-solid-state batteries use non-volatile solid electrolytes that support greater energy density. However, their lithium metal anodes… Read more »
LiTDI: An electrolyte additive for extended battery life and fast charging
Sponsored by Arkema With the electric vehicle market driving a surge in demand for lithium-ion batteries, research is intensifying to develop new electrolytes that not only ensure battery performance, lifetime, and safety, but also enable high-energy anode materials, such as silicon, and cathode materials, such as NMC 811. High purity electrolyte components are crucial to… Read more »
Take that, Coronavirus! Polestar begins production of its EV in China
As auto plants around the world shut down or shift to producing ventilators, Polestar, the performance EV brand owned by Volvo (which is in turn owned by Geely), announced that production of the Polestar 2 would begin this week at its plant in Luqiao, China. The company is taking stringent health precautions: at the factory,… Read more »
Tesla Model Y uses a heat pump to reduce range loss in cold weather
Cold weather poses a challenge for EVs (though hardly a deal-breaker, as thousands of Norwegian drivers can attest). Not only does battery performance take a hit in low temperatures, but the resistance heating systems used in most EVs consume power, reducing range. Tesla has addressed that issue with the design of the Model Y, which… Read more »
Equipmake joins forces with HiETA to create power-dense electric motor
Electric powertrain manufacturer Equipmake has teamed up with additive manufacturing company HiETA Technologies to develop a next-generation motor, codenamed AMPERE. The project is the group’s attempt to produce a lightweight, efficient, low-cost electric motor with peak power density of more than 20 kW per kg. AMPERE is made using additive manufacturing, which allows its metal… Read more »
New potassium metal battery design could solve dendrite problem
In a paper published in Proceedings of the National Academy of Sciences, researchers from Rensselaer Polytechnic Institute demonstrated how they can overcome the dendrite problem to create a metal battery that performs nearly as well as a lithium-ion battery but relies on potassium, which the researchers say is a more abundant and less expensive element….

New machine-learning method could supercharge EV battery development
Battery performance can make or break the EV experience, from driving range to charging time to the lifetime of the car. A team led by Stanford Professors Stefano Ermon and William Chueh has developed a machine-learning algorithm that could lead to longer-lasting, faster-charging batteries. For decades, advances in EV batteries have been limited by evaluation… 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 »
2021 Ford Mustang Mach-E: An electric crossover with “the soul of a Mustang”
It’s almost enough to make you think Ford plans to offer electric cars shoppers may actually want to buy. The extended debut of the 2021 Ford Mustang Mach-E electric SUV culminated in its formal unveiling in an aircraft hangar last November, just before the start of media days at the Los Angeles Auto Show. The… Read more »
