Insights into a hidden flaw could unlock better batteries for EVs
A research team comprised of Princeton, Vanderbilt, and Argonne and Oak Ridge National Labs researchers claims to have uncovered a hidden flaw behind failures in solid-state batteries. In a solid-state battery, ions move through the battery within a solid material, in contrast to traditional lithium-ion batteries, in which ions move in a liquid. Solid-state cells…
Techniques for mitigating thermal runaway in batteries
Thermal runaway happens when a lithium-ion cell, or a small region within a cell, reaches a critical temperature where the materials start to undergo decomposition reactions. These reactions then generate significant additional heat. The decomposition reactions are temperature dependent, increasing exponentially as the temperature increases. Once decomposition starts, a chain reaction causes the battery to…
Researchers develop method of extracting residual energy from waste batteries
A new approach to extracting residual energy from waste batteries could serve as a starting point for waste reduction research Batteries find use everywhere. But once discharged, they are discarded. For many years, discarded batteries have been salvaged for valuable metals. However, the residual energy in them have seldom been recovered. In a new…
Battery backup chemistries for 5G small-cell sites
By JD DiGiacomandrea, Green Cubes Technology As the number of cell sites increase and their sizes decrease, engineers have options to consider for battery backup. Differing battery chemistries offer more choices and different performance levels. Selecting the right battery chemistry for each application is critical to ensure reliable, long lasting, and cost-effective power delivery. The…
Li battery charger IC features programmable charge parameters
Halo Microelectronics announced the release of its HL7090, a fully automatic and highly integrated lithium battery charging management IC with one switching charger, two linear chargers, and full-range programmable charge parameters through an I2C compatible interface. The HL7090 is a compact, flexible, and high-efficiency switching-mode charge management IC for single-cell Li-ion and Li-polymer batteries used…
Next EV anxiety: Cold weather
Leland Teschler • Executive Editor If you wandered around the Society of Automotive Engineers’ annual trade show earlier this year, you would have seen a number of ideas aimed at cutting power consumption in electric vehicles. One development in that category was from a company called BetterFrost. It devised a more energy efficient windshield defroster.…
