Advancements in battery tech

A team of engineers found a way to prevent a chemical layer from forming on Li-ion batteries. This layer prevents fast charging in cold climates. 

What they did was to coat the batteries with a lithium borate-carbonate material about 20 nanometers thick. 

And in tests, batteries can charge up to 5x faster. That's cool.
