The Chinese automaker Chery, which will soon start selling its products in Bulgaria, dropped a bombshell in the world of electric vehicles, presenting a prototype of a solid-state battery with an unprecedented energy density - a full 600 watt-hours per kilogram (Wh/kg). This is one of the highest values announced publicly to date, which opens a new, exciting page in the history of electric transport.
This technological vanguard is revolutionary and categorically changes the rules of the game. Chery's achievement promises a fantastic range of up to 1,300 kilometers on a single charge. Compare this to today's premium electric models, which typically offer only 500-600 kilometers, and the difference is staggering - a twofold jump in efficiency. The new product was officially unveiled at the Global Innovation Conference in the Chinese city of Wuhu, where our team is also present.
The breakthrough is based on a key technological feature: a solid polymerized electrolyte. It boldly replaces the flammable liquid used in conventional lithium-ion cells. In addition, the battery is equipped with a cathode with an increased content of lithium and manganese. This fusion of innovations not only catapults energy density, but also dramatically increases safety.
Chery's solid-state batteries have a number of undeniable advantages that make them the future of the industry:
Safety: They are more resistant to ignition or overheating, even in the event of mechanical damage – the company proudly announced that the prototype has passed drilling and nail tests.
Durability and efficiency: Longer life and flawless performance in extreme heat or cold.
Speed: Faster recharging time.
Ambitious plan: 2027 mass production begins
The Chinese manufacturer's roadmap is clear and ambitious: pilot production will begin as early as 2026, and mass production is planned for 2027. If this plan is implemented, Chery will become one of the pioneers in the world to be the first to commercialize high-energy solid-state batteries, ahead of major competitors such as BYD and CATL.
Despite its amazing qualities, the main problem facing mass commercialization remains the high cost. Currently, solid-state batteries are 2.8 times more expensive to produce than traditional lithium-ion batteries. To overcome this obstacle, the industry will need either major technological breakthroughs that will reduce the cost or significant government support.
Analysts predict that by 2030, solid-state batteries will account for 10% of global production, forming a market worth more than $34 billion. Chery's success will not only be a triumph of engineering thought, but also solidify China's position as a global leader in new energy technologies.
