What does the rise of electric vehicles mean for two critical raw materials that go into their batteries—and for the players in this ecosystem? Theelectric-vehicle (EV) revolutionis ushering in a golden age for battery raw materials, best reflected by a dramatic increase in price for two...
KGI Securities analyst Ming-Chi Kuo, who often relays information gathered from sources within Apple's supply chain in Asia, today shared a trio of new research notes that outline both new and existing predictions about the new iPhone X, iPhone X Plus, and lower-priced 6.1-inch iPhone expecte...
Beyond-lithium-ion batteries are promising candidates for high-energy-density, low-cost and large-scale energy storage applications. However, the main challenge lies in the development of suitable electrode materials. Here, we demonstrate a new type of z
capability of 202 mAh g−1at 15 A g−1as well as admirable cycling stability with a capacity decay of only 0.0043% per cycle over 3000 cycles. Besides, due to the outstanding conductivity and stability of freestanding A-VOx/M heterostructured cathodes, soft-package batteries are assembled ...
Li–S batteries have been actively pursued as a storage device of high energy density. Interestingly, most of the discharging curves for Li–S batteries show either one plateau or two plateaus. Understanding the mechanism and conditions of the one-plateaued discharging curves can provide guidance fo...
The dynamics of Li-ion batteries are often defined by a set of coupled nonlinear partial differential equations called the pseudo two-dimensional model. It is widely accepted that this model, while accurate, is too complex for estimation and control. As such, the literature is replete with numer...
of small batteries, particularly dry cell batteries, has increased rapidly and steadily during the last decade, and a substantial effort has been directed to the production of recharging devices for such batteries, as well as providing means for testing the strength or condition of the batteries. ...
