This approach transformed a \u2018black box\u2019 into a \u2018white box\u2019, unveiling the critical depletion pathways driving cell failure.\u201d<\/p>\n<p>        <a href=\"https:\/\/www.carscoops.com\/wp-content\/uploads\/2024\/02\/2024-Mercedes-Flexible-Charging-System-Pro-4-1.jpg\" data-type=\"inarticle-image-block\"> <\/p>\n<figure class=\"wp-block-image size-large\">\n<p>                    <img decoding=\"async\" loading=\"lazy\" class=\"lazy \" src=\"\" alt=\" EV Battery Breakthrough Could Double Your Car\u2019s Lifespan\" width=\"2200\" height=\"1467\" data-src=\"https:\/\/www.carscoops.com\/wp-content\/uploads\/2024\/02\/2024-Mercedes-Flexible-Charging-System-Pro-4-1-1024x683.jpg\" data-type=\"inarticle-image\" \/><\/p>\n<\/figure>\n<p>        <\/a>  <\/p>\n<p>While previous assumptions pointed the finger at \u201csolvent breakdown, dead lithium accumulation, or solvation environment disruption,\u201d the dominant cause of cell failure is actually the \u201ccontinuous consumption of the electrolyte salt LiFSI.\u201d 71% is consumed by the time the battery dies and the firm says this shows there needs to be a focus on \u201celectrolyte durability as a critical factor for sustained performance.\u201d<\/p>\n<p>CATL used the findings to create an optimized electrolyte formulation with a lower molecular weight diluent. The company says this \u201cincreased the LiFSI salt\u2019s mass fraction, improved ionic conductivity, and reduced viscosity, all without increasing the total mass of electrolyte used.\u201d<\/p>\n<p>If you\u2019re struggling to stay engaged, I don\u2019t blame you, but here\u2019s the key takeaway: the tweak CATL made doubled the prototype\u2019s lifecycle.
