🔥 The Highest Energy Cell in About:Energy Lab: Amprius Technologies, Inc. SA88 at 356 Wh/kg

The Amprius SA88 has just set a new benchmark in our lab, surpassing the Welion 106 Ah semi solid state cell as the highest energy density battery we have tested, based on reported manufacturer values.

⚡2025: Winner Amprius SA88: 356 Wh/kg
⚡2024 Winner: Welion 106 Ah: 347 Wh/kg

Why it matters: In aerospace, energy density is the currency of flight time. Each extra Wh/kg means longer missions, more payload, and greater design flexibility.

🔬 The trade off: With its high silicon content, the SA88 delivers unmatched density but requires applied pressure to manage swelling. Understanding this behaviour is essential for system longevity.

📊 What’s next: Fresh data and validated models for the SA88 will be released in the coming weeks, giving aerospace and UAV teams the tools to integrate this cell with confidence.
