The age of electric road trip anxiety may be nearing its end. A Chinese company, Talent New Energy, has unveiled a prototype for a game-changing solid-state battery that could propel electric vehicles (EVs) to a staggering 2,000 kilometer range on a single charge.
Currently, the longest-range production EV, the Nio ET5, boasts a maximum of 1,055 km according to the Chinese CLTC testing cycle. This translates to a somewhat lower real-world range, especially on highways. Even so, it’s a significant achievement.
But the future of electric cars is poised for a metamorphosis, thanks to the arrival of solid-state batteries. Unlike traditional lithium-ion batteries that use a liquid electrolyte, solid-state batteries employ a solid electrolyte, leading to a major boost in cell performance. The key benefit? Increased energy density, allowing for more energy storage in the same size and weight.
This is where Talent New Energy’s prototype comes in. They’ve developed the world’s first functional, automotive-grade solid-state battery cell with a capacity of 120 Ah and, crucially, an energy density of 720 Wh/kg. By comparison, the mighty 150 kWh semi-solid battery in the Nio ET5 offers just 360 Wh/kg.
Imagine this: Talent’s solid-state battery could potentially double the capacity of existing EV batteries. A car manufacturer like Nio could theoretically create a 300 kWh battery pack that weighs the same as their current 150 kWh pack.
The implications are electrifying (pun intended). This translates to a theoretical range of nearly 2,000 km on the optimistic Chinese CLTC cycle, or a very respectable 1,750 km on the stricter European WLTP cycle.
While Talent has achieved a world record in cell capacity and energy density, it’s important to remember this is a prototype. The exact size of the cell remains undisclosed, but the hope is that solid-state batteries will maintain the same footprint as current lithium-ion options.
The real magic lies in their superior performance. Recharging times are expected to be significantly faster than the current record of around ten minutes. Imagine a world where charging your EV takes a mere five minutes!

The exact timeline for mass production remains unclear, but the first solid-state batteries are expected to hit the streets within the next few years. The MG IM L6, a top-of-the-line electric car, is poised to be the trailblazer, sporting a 1,000 km range on the CLTC cycle (around 800 km on WLTP). This pioneering EV is expected to debut in 2024 or 2025, potentially even reaching European shores.
While the initial wave of solid-state battery EVs might not boast a mind-blowing 2,000 km range, that’s not necessarily a bad thing. In reality, how often do we truly need to travel over 1,000 km on a single charge? The true selling point lies in the potential for incredibly fast charging times, alleviating range anxiety for good. The future of electric cars is undeniably bright, and thanks to advancements like Talent’s solid-state battery prototype, it’s a future that’s hurtling towards us at breakneck speed.
