Theion’s Gen 4 battery, due in 2025, will have a slightly lower gravimetric density of 900Wh/kg, but a higher volumetric one of 1,500Wh/liter – so it would take just over a quarter of the space of a Tesla Model 3 Long Range battery. This would be around 60kg less than the current battery in the Tesla Model 3 Long Range, which has a 374-mile WLTP rating, and would take around a third of the space. Going back to our car with a 900-mile range, its battery would be just 225kg. But the Gen 2 technology is promising to raise this to 700Wh/kg and 1,000Wh/liter in 2023, followed by Gen 3 in 2024 that will deliver 1kWh/kg and 1,200Wh/l. Theion’s current Gen 1 technology is already at 500Wh/kg and 800Wh/liter – well above Tesla’s 2170 cells. Tesla appears to have increased the battery size to provide the latest 305-mile WLTP range while sacrificing some of the acceleration due to the extra weight of LFP.Įhmes claims Theion’s technology will radically increase both gravimetric and volumetric density, so that its batteries either take up less weight and space for the same capacity, or you can have much more capacity for the same weight. When Tesla switched to LFP batteries in the standard Model 3 in Europe, it lost both gravimetric and volumetric density due to deficiencies in this technology compared to Lithium-Ion, but the Model 3’s battery box was designed to fit the larger batteries of the Long Range and Performance, so this base model could simply take up more of the battery box space. Imagine a Tesla Model 3 with 900 miles of range between charges.
