Role of heat transfer materials
Heat transfer plays a vital role in battery packs. Its primary function is to conduct and disperse heat to ensure the performance and safety of the battery. The following briefly introduces the essential role and traditional limitations of heat transfer materials.
The primary role of heat transfer materials:
1. Heat conduction and dispersion: Batteries generate heat when they are in working condition, and heat conduction materials can effectively absorb and conduct it to the external environment to avoid damaging the structure and chemical properties of the battery.
2. Stabilising the temperature of the battery pack: By controlling the temperature in its working state, the heat transfer material can prevent the battery pack from getting too hot or cold.
3. Delay battery aging: temperature control and dispersion can slow down the aging of the battery
Traditional heat transfer materials have limited thermal conductivity, significant weight and space occupation and manufacturing costs, and other shortcomings that can not meet the industry’s increasingly demanding needs. Currently, engineers in the industry are actively developing new multifunctional thermal conductivity materials, such as high thermal conductivity materials and lightweight materials. Multifunctional thermal conductive materials and environmentally friendly low-cost materials.
Introduction of new thermal conductive materials
In recent years, with the rapid development of the new energy industry, the heat conduction industry has emerged with various innovative materials to meet the growing demand for high-performance electronic devices, battery technology-related thermal management systems, and other areas of efficient heat transfer. The following describes the materials and advantages of the most innovative heat transfer materials.
Design and synthesis of multifunctional interfacial materials
Graphene nanosheets, abbreviated as GNSS (Graphene nanosheets) or GNFs (Graphene Nano Flakes), also known as CNFs (Carbon nanoflakes) or CNWs (Carbon nanowalls), are two-dimensional graphite nanomaterials of nanoscale thickness, with the extremes being Single-layer graphene. Graphene has exceptionally high thermal and electrical conductivity and mechanical strength, making it an ideal material for heat transfer because of its thin and lightweight structure. Compared to traditional metallic heat transfer materials, it has the advantage of higher thermal conductivity and lightness and can disperse and conduct heat more efficiently.
Carbon Nanotubes
The tubular structure formed by carbon atoms, with excellent thermal conductivity, electrical conductivity, and mechanical strength, is lighter and more thermally conductive than traditional metal heat transfer materials.
Aluminium Boron Nitride (AlN)
Aluminium Boron Nitride (AlN) is a ceramic material with extremely high thermal conductivity and insulating properties, often used in the thermal management of electronic devices.
These new thermal conductive materials bring new possibilities in thermal management, improving thermal efficiency, efficacy, and sustainability.
Application of new thermal conductive materials in battery packs
Thermal conductive materials play an essential role in battery packs, and their working principle is mainly through thermal management to ensure that the battery cells are shipped at the right temperature. With new heat transfer materials, the current high energy density and high power density battery system better improve the heat dispersion and thermal management effect. trumonytechs listed some of the new heat transfer materials:
Graphene: It can be used as a thermally conductive layer or heat transfer additive in battery packs and is generally used to cover the surface of the battery and penetrate the battery layer. Its high thermal conductivity can quickly disperse heat accumulated in the storm and keep the battery working at the right temperature.
Carbon nanotubes: These can be embedded in the battery material as a thermally conductive coating applied to the battery’s surface, allowing for a more even distribution of heat within the battery to avoid localized overheating.
Aluminum boron nitride material: mainly used in battery heat dissipation and thermal management, sometimes also used for internal insulation layer, thus improving the thermal efficiency of battery components.
Improvement of battery performance by new thermal conductive materials
New heat transfer materials, such as temperature control, pack performance, and battery life, have substantially improved battery performance. The following are some ways to improve the thermal conductivity of the battery pack:
Thermal conductivity
New thermal conductivity materials have higher thermal conductivity, which can conduct the heat generated in the battery pack more efficiently and quickly and help to achieve a more uniform temperature distribution to avoid local overheating and thermal runaway accidents.
Thermal stress
Thermal stress will be generated inside the battery, affecting the battery life. By optimizing heat conduction, the thermal stress caused by temperature changes can be mitigated, reducing the impact on the battery structure.
Enhance energy density and cycle stability
Through more effective thermal management, the battery’s energy density can be better maintained, while the stability and performance of the battery can be better guaranteed.
