Calcium Gluconate gel would be a good idea for the burns. If you were exposed to any HF from the battery fire, it's the standard low-dose treatment used in laboratories where HF is handled (source: worked in a lab where we handled HF, was hit by a tiny droplet once). That said, beyond 24 hours not sure how useful it would be. Lithium Ion batteries don't have heavy metals in them, so there's no risk there.
