Oh, did we mention that they are also extremely thermally stable? Well, they are, just watch the video below.Īt least on paper, everything looks great, except for the energy density, which Natron prefers to not make a fuss about. Its main advantage is the claimed 50,000 cycles lifetime, though, which is between five and 25 times better than what Li-ion batteries offer. Not only that, but Natron’s battery offers an ultra-fast charging time of eight minutes from 0 to 99% state of charge. Natron’s battery relies on different chemistry based on a proprietary Prussian Blue electrode and is said to offer a strong energy density, in between that of lead-acid and lithium-ion batteries. CATL’s Na-ion battery, for instance, offers a 160 Wh/kg which is about half the energy density of today's mass-market lithium-ion packs.

Sodium-ion batteries are a good alternative in this regard.Ĭurrent sodium-ion projects have shown a lower specific energy density, which makes them less desirable than Li-ion batteries. That's why scientists and even companies like the Chinese giant CATL are working hard to replace Li-Ion batteries with alternatives that use more abundant materials.

And other sectors use or will start using Li-Ion batteries. There are not enough lithium reserves on Earth to meet the projected demand for the EV market. Current Li-Ion batteries have allowed for a tremendous advancement in EV development, but they might be doomed already.
