Common Motors is making a daring transfer in battery expertise with a just lately printed patent that goals to revolutionize battery cell packaging. As a substitute of the standard jellyroll design, which resembles a Swiss Roll and has been used because the 1850s, GM proposes an modern “Inverted-U” form that mimics the type of a taco.
This new strategy is meant to reinforce battery efficiency considerably. The standard jellyroll design has been a staple within the trade, however GM’s patent seeks to leverage non-cylindrical cell packaging to advance thermal efficiency—some of the urgent challenges in battery design.
By adopting this Inverted-U configuration, GM asserts that battery cells can obtain higher warmth dissipation. Such enhancements can prolong battery longevity, optimize charging effectivity, and doubtlessly mitigate dangers like thermal runaway. Moreover, this design may result in a discount in cell measurement, bringing prismatic cells nearer to attaining the power density ranges of established cylindrical cells.
GM’s latest endeavors sign its aggressive push into battery innovation. The corporate has shifted away from the Ultium branding for its future initiatives and is shifting past a “one-size-fits-all” battery technique, demonstrating a dedication to creating extra reasonably priced electrical automobiles to compete with an inflow of budget-friendly battery-electric vehicles from worldwide markets.
Whereas this patent represents a promising avenue for GM, it is vital to notice that patents don’t assure manufacturing. Nevertheless, developments in battery expertise are essential as electrical automobiles develop into extra mainstream, highlighting the continuing want for enchancment on this key space.
