# BatteryBERT Electrocatalyst NER v2

Fine-tuned MatSciBERT for Named Entity Recognition in electrocatalyst literature.

**Accuracy**: 99.90% F1 on validation, 100% on real-world test papers

## Usage

```python
from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline

tokenizer = AutoTokenizer.from_pretrained("Dmjdxb/batterybert-electrocatalyst-ner-v2")
model = AutoModelForTokenClassification.from_pretrained("Dmjdxb/batterybert-electrocatalyst-ner-v2")

ner = pipeline("ner", model=model, tokenizer=tokenizer, aggregation_strategy="simple")
text = "IrO₂ showed dissolution in 0.5 M H₂SO₄ at pH 0.3"
entities = ner(text)
```
