Researchers investigate effect of impact on structurally-embedded Li-ion batteries

Green Car Congress

Researchers in China are investigating the effect of low-velocity impact loads on structurally embedded Li-ion batteries in vehicles. —Li et al. The researchers found that embedded batteries experienced micro short circuits during impact-loading process and kept good energy-storage capacity after transient impact.

Prieto introduces latest prototype of 3D Li-ion battery with 3-minute charging

Green Car Congress

All three attributes of Prieto’s lithium-ion battery were tested and validated by a third-party accredited battery testing lab, Prieto said. Today’s batteries use a 2D architecture comprising stacked layers that must always compromise between energy storage and fast charging.

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. The inner SEI is continuous, dense and impermeable to electrolytes, and it is most probably composed of Li 2 O.

Electrochemical energy storage startup SPARKZ licenses ORNL cobalt-free battery tech

Green Car Congress

Stealth-mode electrochemical energy storage startup SPARKZ Inc. has exclusively licensed five battery technologies from the Department of Energy’s Oak Ridge National Laboratory (ORNL) designed to eliminate the use of cobalt metal in lithium-ion batteries. Energy density is especially important for EVs.

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.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

The team’s battery chemistry with the solid electrolyte can potentially boost the energy density by as much as four times above lithium-ion batteries, which translates into longer driving range. The four-electron reaction is enabled by a mixed ion–electron-conducting discharge product and its interface with air.
