BYD says its new Blade Battery offers far lower risk of fire

The popular discussion of EVs tends to center on range, and this has led battery makers to focus on increasing energy density—some would say, at the expense of other equally important attributes such as longevity and safety. Chinese EV giant BYD has introduced a new Blade Battery, which is designed to “bring battery safety back… Read more »

Majority of demand for nickel and cobalt coming from 5 battery suppliers

In 2019, over 59,000 tons of nickel and 14,400 tons of cobalt were deployed globally in passenger EV batteries, a one-year increase of 39% and 34%, respectively, according to data from Adamas Intelligence’s EV Battery Capacity and Battery Metals Tracker. Panasonic used  51% of the global market share of nickel (down from 56% in 2018),… Read more »

UC San Diego’s research roadmap for the challenges of solid-state batteries

The race is on to develop batteries that are less expensive, safer, longer-lasting, more energy-dense, and easily recyclable. All-solid-state batteries show promise, but obstacles to their wide-scale adoption remain. In a review article published in Nature Nanotechnology, nanoengineers at the University of California San Diego (UCSD) offer a research roadmap that discusses four challenges of… Read more »

Fortum, BASF and Nornickel to partner on battery recycling

Finish utility company Fortum, German chemical company BASF, and Russian mining company Nornickel have signed a letter of intent to develop a battery recycling cluster in Harjavalta, Finland. The companies aim to promote the production and use of recycled raw materials in the EV battery market. BASF will use the recycled materials in its planned… 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….

Lilac Solutions to use novel technology to extract lithium from the Salton Sea

Beneath California’s Salton Sea lies a vast pool of super-heated fluid that’s long been exploited as a source of geothermal power. The underground reservoir is also rich in lithium, but over the years, so many companies have tried, and failed, to economically extract the light white stuff, that the area has been called a “graveyard… Read more »

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 »

Henkel and Covestro develop adhesive solutions for efficient Li-ion cell assembly

With the aim of lowering the cost of battery manufacturing, Henkel and Covestro have developed a joint solution that enables the efficient fixation of cylindrical Li-ion battery cells inside a plastic cell holder. The design is based on a UV-curing adhesive from Henkel and a UV-transparent polycarbonate blend from Covestro. Henkel’s Loctite AA 3963 battery… Read more »
