Are silicone-based thermal interface materials a good choice for electric vehicles?

However, it is already apparent that silicone-based thermal interface materials will play a key role in future thermal management. They can be readily adapted to a wide variety of application and manufacturing methods and are therefore the thermal interface materials of choice for mass production of electric vehicles.

What are silicone-based thermal interface materials?

Silicone-based thermal interface materials, i.e. heat-conducting materials comprising a matrix of cured or uncured silicones, have a long successful track record in power electronics assemblies. Silicones are widely known for their aging resistance – even upon exposure to high or low temperatures.

Do lithium ion batteries overheat?

Lithium-ion batteries only deliver their best performance at temperatures between 20 and 35 °C. Consequently, to ensure acceptable performance and life span, they need to be prevented from overheating. Heat is also generated by the electric motor and the power electronics.

Why do we use silicone based thermal interface materials?

They ensure that the TIM remains electrically insulating, a property which is essential for use in close proximity to live components. Silicone-based thermal interface materials, i.e. heat-conducting materials comprising a matrix of cured or uncured silicones, have a long successful track record in power electronics assemblies.

Why is thermal management important for lithium ion batteries?

Such thermal management is especially critical for the battery serving as the power source. Lithium-ion batteries only deliver their best performance at temperatures between 20 and 35 °C. Consequently, to ensure acceptable performance and life span, they need to be prevented from overheating.

Why do we use thermally conductive silicone adhesives?

The use of thermally conductive silicone adhesives obviates the need for other means of attachment, as they not only provide thermal coupling between the parts, but also bond them together. Silicone pastes maintain their consistency after application.
