Artificial Intelligence
We build the first AI-powered battery intelligence
Fast-Track Battery Innovation through AI-Generated Synthetic Data
Traditional battery modelling is slow and resource-intensive. Our AI-driven approach reduces time and cost by generating synthetic data for all key performance and lifetime modalities. This enables rapid prototyping, faster iteration cycles, and improved decision-making for R&D and production teams.

| Traditional Modeling Modelling of specific battery cells based on ECM or Finite-Elemente-Methode | Sphere Foundation AI Approach Foundation AI based multi chemistry modelling. | |
|---|---|---|
| Model Training Complexity | High Requires detailed understanding of physics and chemistry, complex meshing, and material properties. | Moderate to High Requires large datasets for training, but less domain-specific expertise once the AI model is pre-trained. |
| Input Data Needed to Fine-Tune Models | Physical & chemical data Detailed experimental data, material properties and cell design specs | Large-scale time series data Historical usage data, charge/discharge cycles, environmental conditions. |
| Simulation Speed | Slow FEM sim are computationally intensive, especially for 3D models. ECMs are faster but less detailed. | Fast Once trained, AI models can simulate quickly, often in real-time or near real-time. |
| Prediction Accuracy - General | High for specific phenomena Accurate when parameters are well-defined and calibrated. | Potentially higher and adaptive Improves with time & more data, capturing complex patterns and anomalies. |
| Prediction Accuracy - State of Health (SOH) | High when specific degradation mechanisms are well-understood and modeled. | Potentially higher for long-term predictions, leveraging large datasets and continuous learning. |
| Self learning capabilities | None every model needs to be trained again when design changes are introduced | High the model grows over time and implements learning to improve its ability to predict performance and identify anomalies |
| Include other (than time series data) sources into simulation | Not possible | High Including e.g.: tear down images, SEM of macroscopic features |
| Generalizability Across Cell Chemistries | Limited requires re-parameterization and validation for different chemistries | High can generalize, applicable to various chemistries with minimal re-training. |
