> Better range on a lower capacity means much better range per hour charging time. That's not what they're saying, this is about space required to get the same capacity. The relevant quote is "meaning that energy density at the pack level should compensate". What's going on is that the chemistry energy density is lower, so you need bigger batteries to get the same capacity (i.e. range). Normally this means you would need more space in your vehicle to get the same range, however you need less cooling so you save some space there so the overall space usage of the battery system ends up about the same.
