v0.6.0 - Pouch-cell thermal-gradient model

Pouch-cell through-thickness thermal-gradient model

This release adds a toolbox-free, one-dimensional finite-volume reference for spatial thermal behavior in a lithium-ion pouch cell with asymmetric face cooling.

Engineering capabilities

• resolves 15 cell-centered through-thickness temperatures by default
• combines internal volumetric heat generation, through-plane conduction, and independent face convection
• reports inferred surface, center, volume-average, and hot-spot temperatures
• exposes every interface and boundary heat flow
• closes node-level and whole-cell discrete energy balances
• accepts native irregular timestamps or a requested uniform sample time
• rejects malformed inputs and unstable explicit time steps

Independent validation

• all 15 MATLAB and Simulink checks passed on MATLAB R2026a
• MATLAB Code Analyzer reported zero issues across the five new MATLAB files
• the symmetric case matches the continuous steady-state slab center temperature within 0.003 degC
• the medium-to-fine spatial-grid center difference is 0.0024 degC
• citation metadata and Markdown links passed their GitHub Actions gates

Canonical asymmetric-cooling result:

Peak node temperature: 43.83 degC at 5.60 mm and 1800 s
Peak through-thickness node spread: 3.09 degC
