Under the settlement, Sony and Sony Electronics have agreed to license 3M-developed materials for cathodes, which are the positive electrodes in batteries. Terms of the agreement were not released.
The components involved had nothing to do with the battery recalls over the last few years. Still, given Sony's current status in the market as a battery manufacturer, if I was 3M I'd be staying as far away from their batteries as I could get.
Whether or not the settlement applies to the other companies isn't clear, but it most likely doesn't.
