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.
