Thermal Management
Thermal Management is a crucial area in battery technology that deals with controlling and maintaining proper temperature in battery systems. Think of it like a sophisticated cooling and heating system that keeps batteries at their ideal temperature - not too hot and not too cold. This is important because batteries, especially in electric vehicles and large energy storage systems, can get very hot during use or charging. Without proper thermal management, batteries can become unsafe or wear out faster. This field combines aspects of engineering that focus on heat transfer, cooling systems, and safety measures to make batteries work better and last longer.
