Battery manufacturers are currently challenged to produce large volumes of smaller, lighter, and cheaper lithium batteries.
These higher energy density packs deliver more power, over a longer period of time, but to do so they need to avoid overheating and heat spikes, i.e. better thermal control.
In order to maintain proper operation of a battery cell, cooling must be applied to its outer surface since it is not possible to cool the entire active area of the electrodes. This is necessary to prevent temperature gradients, but also poses a challenge as it reduces the overall energy density of the battery.
To overcome this, thermal conduction must be taken into account when cooling the cell.
Thermal conduction or Thermal conductivity is the ability of a substance to transfer the kinetic energy of its molecules to other adjacent molecules or substances with which it is in contact, i.e., the physical property of materials that measures the ability to conduct heat.
The higher the thermal conductivity of a material, the better it conducts heat.
To extend a material’s lifetime, power, and performance, Coolmag has developed a range of products based on a thermally conductive, flame-retardant, two-component potting resin that combines easy processing with improved thermal conductivity.
The application of this range of resins maintains batteries electrically and ionically as it conducts heat while maintaining the safety level of the battery after numerous charge and discharge cycles.
This range of resins has been formulated to meet customer needs, more or less conductivity, more or less density, etc. It is also versatile as it can be used either for encapsulation or as a liquid gap filler.
Siloxanes Are chemical compounds with a backbone of alternating silicon (Si) and oxygen (O) atoms, each silicon atom bearing one or several organic groups, as be seen in the image 1, are very flexible due to large bond angles and bond lengths compared to those found in more basic polymers. Siloxanes are building blocks for silicone …
The demand for effective thermal management solutions in electronic equipment is on the rise as a result of rapid technological progress. These solutions aim to ensure that system devices operate at an acceptable temperature level to reduce the risk of damage and ensure the longevity of components. The traditional method of dealing …
Temperature it is a bottleneck for all power electronics in general, that’s a fact. We need safer, more efficient, and reliable electronics but as we are taking power density values to the limits, thermal performance becomes a tricky topic. Not only because thermal compounds have to fit all these technical requirements ( …
