Until recently, even with different technologies, the battery industry followed a fairly simple logic: everyone was trying to improve the same things. The data was always longer range, faster charging, lower costs. It was a shared race, with technical variations, but in one direction.
Today this logic is no longer valid.
Not because new chemistry has emerged in an absolute sense, but because the way in which they are developed and used has changed: we no longer optimize a single process, but several processes at the same time, sometimes with very different objectives. In practice, there is no longer one benchmark. In some cases the charging speed is important, in other cases the energy density and in still other cases the costs and scalability.
This is the real phase change: the competition is no longer about ‘who makes the best battery’, but about who can build the right system for every application.
There are more variants and options than ever. LFP [lithium iron phosphate] will continue to dominate where cost, safety and sustainability matter; NMC [nickel manganese cobalt] and “condensed” or semi-solid variants where density and performance are crucial; sodium ion in contexts where scalability and availability of raw materials are crucial; solid-state in high-end segments, where weight and safety are more important than absolute costs. The competition is therefore no longer about ‘the best battery’, but about the ability to build coherent technology portfolios and actually put them into production.
It is in this context that CATL’s Technology Day on April 21, 2026 should be read as more than a product launch event and actually the presentation of a comprehensive industrial vision. Shenxing III pushes extreme charging, with stated values down to 10°C and times of less than 4 minutes to reach 80%; Qilin III consolidates the premium segment with approximately 280 Wh/kg and a range of approximately 1,000 km; Qilin Condensed raises the bar even higher, up to 350 Wh/kg and a range of up to 1,500 km; Freevoy II redefines the role of hybrids with an electric range of up to 600 km and a total range of more than 2,000 km; Naxtra introduces mass production of sodium ions, expected by the end of 2026.
The key, however, is not the numbers themselves, but the overall design. CATL shifts the focus from the battery as a component to the battery as a system. If ultra-fast charging truly becomes industrialized, range will no longer be the main issue. If density increases without compromising safety, the positioning of premium cars will change. When CATL sodium ion comes into productionwill change cost structures and supply chains. And indeed, CATL isn’t just focusing on cells: it’s integrating ultra-high-power charging and battery swapping, as well as trying to master the infrastructure that makes these technologies useful.
BYD’s strategy is different, but equally clear. The company focuses on full vertical integration between battery, vehicle and charging. With the Super e-Platform, it introduced 1,000 V architectures and charging systems up to 1 MW, with the aim of bringing the refueling experience closer to that of combustion engine vehicles. The updated second-generation Blade Battery goes in the same direction: long range, fast charging and stable performance even at low temperatures. BYD does not aim to be a one-size-fits-all supplier, but rather a manufacturer that shows what happens when the entire system is designed together.
In addition to these two industrial models, a group of players is mainly working on the technological leap. Gotion High Tech is one of the most active. It has already launched fast charging solutions while accelerating its efforts in semi-solid and solid-state, with indicated densities up to 350 Wh/kg and pilot lines already operational. The approach is clear: build a gradual industrial path to solid-state, without waiting for a sudden technological breakthrough.
A similar logic can be found in EVE energythat combines two paths: on the one hand, ultra-high-density grid storage – with systems of almost 7 MWh in 20-foot containers – and on the other, the development of advanced batteries for high-value markets, such as drones, humanoid robots and more. This is where new chemistry can enter first, where every kilogram saved and every increase in safety has a direct impact on the business model. It is precisely in these sectors that the most interesting effects are starting to become visible. Professional drones, humanoid robots and eVTOLs do not have the cost constraints of mass-produced automotive vehicles, but they have much stricter weight, range and safety requirements. It’s no coincidence that companies like Samsung SDI and LG Energy Solution are focusing their most advanced roadmaps precisely on these applications, clearly indicating that solid-state technology could arrive here before it does in cars.
Where the similarities with EV batteries end
Meanwhile, the stationary storage sector is on a nearly opposite trajectory. The priority here is not the highest possible density, but the best balance between costs, cycles, safety and integration. LFP will remain dominant, but even here the jump is clear: 20-foot containers have gone from 3 to 4 MWh to over 6 to 7 MWh in just a few years, with some manufacturers going even further. The effect is structural: less space, fewer components, lower system costs per installed MWh.
In this context, sodium ion represents a key variable. Not for absolute performance, but for scalability. Greater availability of raw materials, less exposure to geopolitical constraints, potentially more stable costs. With mass production expected between 2026 and 2027, this technology is likely to quickly find its way into storage and less energy-intensive applications, reshaping the balance of the industry.
Prices also confirm this shift. After a reduction of approximately 90% in the past ten years, battery packs have reached an average level of around $100 per kWh, with storage already at lower levels. But the dynamics are no longer just a learning curve: it is the result of industrial scale, cell size and chemical diversity. In the coming years, the key driver will be the ability to produce at TWh scale while maintaining control over costs, supply chain and integration.
When we look at the bigger picture, the shift is clear. Until yesterday, the sector was driven by a single logic. Nowadays it is becoming more and more segmented. Tomorrow – in five years – it will probably be organized as a real industrial platform with multiple markets: batteries for the electricity grid, for mass-market cars, for premium products, for robotics, for light aircraft. And each segment will have its own leaders.
In other words, the battery is no longer a simple component. It will become the transversal energy infrastructure of the next industrial cycle. And those who can master not only the technology, but also production, integration and the grid, will have an advantage that will be difficult to regain.
The phase change is not in the future, but is already underway, and as is clear, China is leading it.
