A closer look at how batteries fail
A lot of research has been done to improve lithium-ion battery safety, cycle life and power output over a range of high and low temperatures, yet understanding the fundamental processes and degradation mechanisms in Li-ion batteries remains a challenge. To understand the degradation processes of lithium-ion batteries, it is important to understand how they operate…. Read more »
BMW and Samsung expand supply agreement for battery cells
BMW and Samsung SDI plan to expand their supply relationship for EV battery cells. The two companies have signed a memorandum of understanding that includes an increase in quantities delivered as well as further technological development of battery cells. BMW produces high-voltage batteries for the i3, i8 and other future hybrid vehicles at its plant… Read more »
Wildcat’s new copper fluoride cathode material offers 2.5x more capacity than today’s battery tech
The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »
VW: e-Golf battery pack doesn’t need a liquid cooling system
Does an EV battery pack need a liquid cooling system? Automakers have different opinions. The Tesla Roadster and Model S have ‘em, the Nissan LEAF does not. Volkswagen initially designed its e-Golf with a liquid-cooled battery, but the production e-Golf, which is now on sale in Germany, and will arrive in selected US markets during… Read more »
Scientists discover the secret of aging (of lithium-ion batteries)
Aging is an inescapable fact of life, not only for people, but for batteries as well. Researchers at the Helmholtz Center Berlin (HZB) recently identified a major reason why Li-ion batteries degrade with time. They have directly observed atomic rearrangements occurring in cathode materials during charge and discharge processes, which lead to the breakdown of the… Read more »
