CATL promises 1,500 km range: science or marketing?

At the Beijing Auto Show, CATL, the world's largest battery manufacturer, unveiled its new generation of Qilin batteries with figures that fire the imagination: 1,500 kilometers of range and a full charge in just over six minutes. The company, which is already building a plant in Spain, is thus trying to pull ahead of its great rival BYD in the war over the electric car.

But skepticism was quick to appear. A quick look at the numbers raises red flags: to store 1,500 km of range at a consumption of 15 kWh/100 km, you need 225 kWh of capacity. To recharge that energy in 6 minutes, the required power would be 2,250 kW — an absurdity compared with today's ultra-fast chargers, which run at around 400-600 kW. Neither existing infrastructure nor anything planned for the short term can handle such a demand.

Physics versus marketing

Several analysts point out that even if the battery achieved that energy density, the bottleneck lies in the charging network. 350 kW chargers already heat up the cables; multiplying the power sixfold would require cooling solutions and power grids that do not exist today. Moreover, the chemistry of lithium-ion batteries itself has limits: advances in energy density are incremental, not revolutionary. The argument that "they are already being tested in buses" runs up against the reality that technology for heavy vehicles does not scale directly to passenger cars.

The infrastructure gap

Beyond the hype, the key question remains the same: without enough charging stations and without plugs in garages, a 1,500 km range is irrelevant. As skeptics point out, the problem with the electric car is not range — most models already offer 300-500 km — but the charging infrastructure. Until that is solved, XXL batteries will only be a luxury for those who can charge at home. And at today's prices, the extra cost only pays off with a lot of miles driven.

The 2030 horizon

With the EU calendar setting 2035 as the deadline for combustion engines, the pressure for viable batteries is at its peak. CATL is betting on spectacle, but the data from chemistry and electrical engineering suggest we have years of modest improvements ahead. The question is not whether the electric car will arrive, but how many European brands will survive while the Chinese advance with aggressive marketing and state subsidies.
