Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process. . …

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Stanford / SLAC’s new lithium-polysulfide flow battery design compared to conventional “redox” flow batteries. The new flow battery uses only one tank and pump and uses a simple coating instead of an expensive membrane to separate the anode and cathode. Credit: Greg Stewart/SLAC).

KIST researchers develop promising solid electrolyte for solid-state batteries

Green Car Congress

Researchers at the Korea Institute of Science and Technology (KIST) have developed a superionic halogen-rich Li-argyrodite (HRLA) that works well as a promising solid electrolyte (Li 5.5 Cl 1.5 ) in all-solid-state batteries without a decreased intrinsic electrochemical window in various electrode configurations.

Researchers develop real-time picture of formation of solid–electrolyte interphase of a Li-ion battery

Green Car Congress

During the first charging process of a new Li-ion battery cell, trace amounts of electrolyte components decompose sacrificially to form what is called a solid–electrolyte interphase (SEI) on the anode surface. Then the team analyzed the SEI components using a mass spectrometer. —Zihua Zhu.

Study shows paper-folding concepts can compact a Li-ion battery and increase its areal energy density

Green Car Congress

Researchers at Arizona State University have shown that paper-folding concepts can be applied to Li-ion batteries in order to realize a device with higher areal energy densities. Recently, there has been much interest in the development of electronic and energy storage devices using paper and textile components.

Roskill: Niobium industry looking for a future beyond steel; Li-ion batteries a possibility

Green Car Congress

Non-steel applications account only for a couple of percentage points in terms of consumption but electrical vehicles (EVs) batteries and nanocrystalline applications could grow at a double-digit rate in the next decade, depending on technological developments. Niobium and batteries. The paper (Griffith et al. ) Griffith et al.

UCR researchers find commercial fast-charging damages EV batteries, propose new internal-resistance-based technique

Green Car Congress

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, according to researchers at the University of California, Riverside (UCR) in a new open-access study published in the journal Energy Storage.
