Looks like some interesting lab research:

The team needed to prevent that surface layer from forming. They did this by coating the battery with a glassy material made of lithium borate-carbonate, approximately 20 nanometers thick. The addition of this coating sped up cold charging significantly, and when combined with the channels, the team’s test cells were 500% faster to charge in subfreezing temperatures.

I help manage a fleet of Rivian vans for work. As amazing as they are, the subfreezing temps can make it really difficult to have an electric fleet. It's worth it, but so many issues come up because of the slow charging in winter. I'm hopeful this type of engineering can be scaled and successful, because that's one of the only issues I have with electric vehicles.
