Solid State Batteries

2023

A Promising Technology for a Sustainable Future in Africa

Solid state batteries have emerged as a promising technology in the field of energy storage, offering higher energy density, faster charging, longer life, and improved safety compared to conventional lithium-ion batteries. While most research in this area is conducted in the global north, it is important to also consider the potential of this technology in Africa, where energy access and sustainability are major challenges.

As a leading environmental and sustainability organization in Kenya, Green Credits Kenya is interested in exploring the potential of solid state batteries in addressing these challenges. With the growing demand for energy in Africa, particularly in rural areas where access to electricity is limited, solid state batteries could offer a more sustainable and affordable solution.

In this blog post, we will discuss the benefits and challenges of solid state batteries, their potential applications in Africa, and the importance of conducting research from a Kenyan, African, and global south perspective to ensure that the technology is suitable and accessible for all.

All-Solid-State Batteries (ASSBs) – Africa’s Virtual Grid (2026)

The "Lodwar vs. Brussels" gap in battery tech is being closed by Oxide-Polymer Composites.

Solving the Heat and Sand Problem

Traditional Lithium-ion batteries have a "liquid" electrolyte that becomes volatile in the heat. 2026 ASSBs have replaced this with a solid ceramic or polymer.

• The 130°C Test: New 2026 prototypes have endured temperatures up to 130°C without requiring active liquid cooling. This is a game-changer for containerised battery logistics, as it reduces the energy needed just to keep the "cargo" from exploding.
• Energy Density: We are seeing 350–400 Wh/kg in pilot production. For electric trucks, this means lighter containers and more electricity delivered to the village.

The "Sulfide" vs. "Oxide" Debate for Africa

• Sulfide Electrolytes: They charge faster but are sensitive to moisture (humidity). In Kenya, these are risky for coastal use.
• Oxide Electrolytes: These are much more stable and "rugged," but harder to manufacture. 2026 research is favoring Oxide-Polymer hybrids for rugged logistics because they combine the stability of ceramics with the flexibility of polymers.
