Sodium-ion batteries, Lithium-ion batteries

Learn about Indi Energy’s groundbreaking work and the potential of sodium-ion batteries.

Indi Energy’s sodium-ion batteries embody a hopeful vision for a sustainable future. Not only do they provide a safe and cost-effective alternative to lithium-ion batteries, but they are also environmentally friendly, utilizing readily available materials. These batteries have the transformative potential to revolutionize our energy usage and storage practices. In a world grappling with environmental toxicity, global warming, and the challenges posed by the limited supply of lithium, cobalt, and nickel reserves, the quest for an alternative energy storage solution becomes imperative. Indi Energy’s sodium-ion batteries emerge as the long-awaited solution, offering a beacon of hope for a greener tomorrow. In this blog post, we will delve into the advantages of sodium ion batteries, their increasing demand, and the groundbreaking efforts of Indi Energy, an Indian startup revolutionizing energy storage technologies.

Why is there an increased demand for sodium-ion batteries?

It is worth noting that lithium resources, despite being spread out worldwide, have relatively small reserves. This not only poses challenges for transportation but also leads to a production cost exceeding $20,000 per ton. Surprisingly, the majority of the world’s lithium supply is located beneath the sea flats, specifically in the region known as the ‘lithium triangle,’ encompassing parts of Chile, Argentina, and Bolivia. Astonishingly, extracting lithium requires a staggering 500,000 gallons (or 2.2 million litres) of water per ton, resulting in a significant depletion of water resources in the area. Unfortunately, the impact of lithium mining goes beyond water scarcity. Since lithium is not found in its elemental form, the process of separating it from other elements incurs substantial environmental costs. Contamination of soil, water, and air becomes a significant concern. While recycling lithium-ion batteries holds the potential for mitigating the adverse effects of mining, progress in this area has been limited.

As environmental concerns intensify, the demand for sodium ion batteries continues to surge.

Three key factors contribute to this increased demand:

  1. Environmental Friendliness: Sodium-ion batteries offer an eco-friendly solution by minimizing environmental toxicity associated with traditional energy storage technologies.
  2. Abundant Resource: Sodium reserves are nearly 500 times greater than lithium reserves, making sodium an abundant and sustainable resource for battery production.
  3. Enhanced Performance: Sodium-ion batteries outshine lithium variants in various aspects. They charge faster, boast a three-times higher lifecycle, exhibit stability over a wider temperature range, and are non-flammable, ensuring safer usage.

Are sodium-ion batteries available commercially?

The Commercialization of Sodium-Ion Batteries: In 2023, sodium-ion batteries are poised to enter the commercial market. Noteworthy companies such as Faradion (UK), Natron Energy (USA), CATL, HiNA Battery (China), and Indi Energy in India are leading the final stages of development. A significant milestone occurred on February 27, 2023, when HiNa Battery and JAC Auto launched the world’s first electric vehicle powered by sodium-ion batteries. This compact five-seater boasts a battery pack with a 25 kWh capacity, an energy density of 120 Wh/kg, and a range of 252 km.
Implications and Benefits: The adoption of sodium-ion batteries yields numerous benefits. Their sustainability, safety, lower cost compared to lithium, and abundance of sodium reserves will significantly reduce the overall price of electric vehicles. This progress will make EVs more affordable and accessible to the general public, paving the way for a sustainable transportation revolution.
