    I'm seeking an expert in thermal analysis and materials science to help with a comprehensive project. 1. Thermal Gradient Analysis: - The main focus will be on quantifying thermal gradients within individual Li-ion cells and across modules in extremely low winter conditions. - You will need to assess the impact of these gradients on the lifespan of the battery, as this is my primary concern. 2. Material and Design Optimization: - I want you to explore advanced thermal interface materials (TIMs) and innovative module designs to minimize the thermal gradients. - This includes investigating novel materials with better thermal conductivity that can still be compatible with existing Li-ion technologies. 3. Thermal Management Strategies: - The development of ta...
