Welcome to the forty-fifth issue of “Sodium-ion Batteries Technology Updates,” a series from Indi Energy, one of the world’s leading sodium battery companies and India’s first indigenous sodium-ion battery manufacturers.

Indi Energy is a DRDO 3.0, NSA’22, & SIDBI Environmental Challenge’24 winner and one of the world’s leading sodium battery companies involved in developing, and commercializing sodium-ion batteries and customizable sodium-ion battery packs.

As part of the Make in India initiative, Indi Energy has its own supply chain for our sodium-ion batteries, which is completely indigenous, a.k.a. homegrown. We are setting a new benchmark in the energy storage sector by transforming energy storage solutions sustainably. 

In this forty-fifth issue of sodium-ion battery technology updates, we will go through the recent updates in the world of sodium-ion batteries, the energy sector, and an overview of the global energy outlook. 

The key factors that decide battery size

The size of a battery is influenced by several key parameters crucial for optimal performance across different applications.

1. Power Requirement: From smartphones to electric vehicles like the Hummer EV, power demand dictates battery size. The larger the device, the more substantial the battery is needed.
2.  Voltage: Specific voltage requirements tailor the type and size of batteries to power various devices effectively.
3. Capacity: Total charge storage directly impacts runtime, crucially determining battery size based on energy consumption needs.
4.  Physical Size & Weight: Form factor and user comfort play roles in determining battery size, especially in portable devices like smartphones.
5.  Discharge Rate: High discharge rate needs, such as in electric vehicles and grid energy storage systems, influence battery size for maintaining efficiency.
6. Cycle Life: Battery longevity, measured in charge/discharge cycles, determines the practical size needed for sustained performance.
7. Energy Density: Higher energy density enables more energy storage in smaller, lighter batteries, impacting their overall size and weight.

Understanding these parameters is pivotal for optimizing battery size across diverse applications. At Indi Energy, we leverage these insights to innovate with sodium-ion technology that meets evolving energy storage needs sustainably. Our sodium-ion batteries feature:

• Working voltage: 3.0-3.8 V
• Gravimetric Energy Density: 120-140 Wh/kg
• Cycle life: Over 2000 cycles

Meeting a great mind – Prof. Stefan Adam

At Indi Energy, we are dedicated to empowering energy independence by exceeding global standards in sustainable battery technology—a vision that has been driving us forward for the last five years. We were thrilled to host Prof. Stefan Adams from the National University of Singapore recently. Prof. Adams is at the forefront of developing sustainable energy solutions, combining advanced experimental and computational approaches to enhance the performance of Li/Na-based batteries, metal-air batteries, and redox flow batteries.

His pioneering work on battery lifecycle studies, performance management during second life, and battery material recycling aligns perfectly with our mission to drive innovation in sustainable energy. Moments like these, when top experts in sustainable battery technology come together, are crucial for catalyzing the exchange of ideas and driving innovation. Indi Energy wholeheartedly expresses gratitude to Prof. Adams for his invaluable insights! Here’s to advancing sustainable energy solutions, one breakthrough at a time!

At Indi Energy, one of the world’s leading sodium battery companies, we are harnessing sodium, one of Earth’s most abundant elements, integrating it with our proprietary, BioBlackTM—bio waste and agricultural waste derived organic hard carbon, sodium-ion cathode, and sustainable liquid sodium electrolyte. They form the core components of our sodium-ion batteries and customizable sodium-ion battery packs, capable of delivering optimum performance while setting the industry’s highest safety standards. 

Our sodium-ion battery technology represents a cost-effective, environmentally friendly alternative to traditional lithium-based batteries 🔋, ensuring affordable and accessible energy storage solutions that will promote sustainable energy practices, benefiting society and driving economic growth.

The potential impact of our sodium-ion batteries on climate action has led to Energy Alternatives India and The Better India naming Indi Energy as one of its “Top 100 Innovative Indian Startups in Climate Action,” and “5 Innovating Startups Revolutionising India’s Renewable Energy Sector.”
