STOREN TECHNOLOGY
Why Sodium? The Smart Alternative to Lithium.
A new generation of energy storage, built around abundant resources, safety and sustainability.
Abundant & Widely Available
Sodium is one of the most abundant elements on Earth and is widely available around the world. Unlike lithium and other critical battery materials, sodium can be sourced from widely accessible resources, reducing dependence on geographically concentrated raw materials and supporting a more resilient energy storage supply chain.
Cost-Competitive
By using sodium instead of lithium and reducing reliance on critical and costly raw materials, Sodium-Ion technology has the potential to deliver a more cost-competitive energy storage solution. Its accessible raw material base also supports the development of a scalable and resilient supply chain.
Designed for Safety
Sodium-Ion technology offers an intrinsically robust approach to energy storage. Its chemistry can provide high thermal stability and reduced dependence on highly reactive materials, making it a promising solution for safe and reliable stationary energy storage applications.
A More Sustainable Choice
Sodium-Ion batteries offer a promising pathway towards more sustainable energy storage. The use of abundant and widely available materials can reduce pressure on critical mineral resources while supporting the transition to renewable energy and a more resilient energy system.
HOW SODIUM-ION TECHNOLOGY WORKS
Sodium-Ion batteries store and release energy through the reversible movement of sodium ions between the cathode and anode.
BATTERY CELL
The battery cell is the core of a Sodium-Ion energy storage system, where electrical energy is stored and released through the reversible movement of sodium ions. During charging, sodium ions move from the cathode to the anode through the electrolyte. During discharge, the ions move back to the cathode, while electrons flow through the external circuit to deliver electrical energy.
ANODE
The anode is the negative electrode where sodium ions are stored during charging. As the battery charges, sodium ions move from the cathode through the electrolyte and are inserted into the anode material. During discharge, the ions move back toward the cathode while electrons flow through the external circuit.
CATHODE
The cathode is the positive electrode of the battery and plays a key role in storing and releasing sodium ions. During charging, sodium ions are extracted from the cathode and move through the electrolyte toward the anode. During discharge, the ions return to the cathode, enabling the battery to release stored energy.
ELECTROLITE & SEPARATOR
The electrolyte provides the medium through which sodium ions move between the cathode and anode. A separator keeps the two electrodes electrically isolated while allowing sodium ions to pass through. This controlled ion movement enables the reversible charging and discharging process of the battery.
