Electric Vehicles
On this page
The electric vehicle stopped being a bet sometime around 2025. In that year global EV sales crossed 18 million units, with China alone past 12 million, and the question quietly inverted: not whether electric drivetrains would win the mass market, but how fast the factories, chargers, and supply chains can be built to meet the demand they have already created. The drivetrain was never the hard part. The battery was — and the battery problem is now largely an economics and infrastructure problem rather than a physics one.
Parity, and the chemistry that delivered it
The decisive event is price parity: in several segments, and across most of China, an electric car now costs the same or less to buy than its gasoline equivalent, before counting cheaper fuel and maintenance. What made that possible is less any single breakthrough than a chemistry shift toward LFP (lithium iron phosphate), which by 2025 accounted for more than half of all EV batteries. LFP is often more than 40% cheaper per kilowatt-hour than the nickel-rich chemistries it displaces, and its arrival in Western entry-level models from BYD, Tesla, VW, and Stellantis is finally attacking the volume heart of the market — the affordable cars that premium, range-obsessed designs could never reach. The chemistry itself lives on battery technology; here the point is what it did to the showroom floor.
Range and charging stop being the conversation
For most drivers, range anxiety is already a solved problem on paper: ordinary LFP packs deliver 350–500 km in a compact crossover, more than enough for typical use. The next leap belongs to solid-state cells, which promise 600–1,000+ km in optimized vehicles together with 10-to-15-minute charges to 80% and far better cold-weather behavior — though serious volumes are not expected until the late 2020s. Meanwhile the charging side is catching up through 800-volt architectures and 350–500 kW chargers now rolling out along highways in China, Europe, and the United States, which compress a long-distance top-up into a coffee break. The remaining friction is not the car; it is whether the chargers and the local grid are there when you arrive.
Trucks and fleets: where the math is hardest and clearest
The least glamorous segment may matter most. Electric truck demand more than doubled in 2025, and Class 8 battery-electric and hydrogen fuel-cell trucks are both winning real orders as total cost of ownership crosses diesel in high-utilization fleets — the vehicles that run enough miles for cheap electricity and low maintenance to overwhelm a higher sticker price. Fleets decide on spreadsheets, not vibes, which makes their adoption a particularly honest signal.
The China lead and its long shadow
Behind every cheap pack sits a supply chain that is overwhelmingly Chinese: China holds more than 80% of global cell capacity and much of the upstream refining and precursor production. That concentration is the central geopolitical fact of the transition — a single point of leverage over the cars, grids, and industries of everyone else. Two forces push against it. LFP and emerging sodium-ion chemistries cut dependence on nickel and cobalt, shrinking the list of contested materials; and deliberate diversification across the US, EU, Indonesia, Morocco, and Australia — pushed hardest by the IRA's domestic-content credits — is slowly building alternatives. Both face multi-year lead times. For now, the most affordable path to an electric future runs through Chinese factories, and untangling that is a project measured in decades.
