Key stats from the article: current lithium-ion batteries store roughly 400 watt-hours per kilogram
We need roughly 700 - 800 (w-h)/kg for electric cars to work, and we need it cheap so that we can deploy these things everywhere.
The article quotes a new tech that could get us 1300, and that's exactly why ARPA-e is funding it. Let's hope this works out.
