The world of lithium-ion batteries is witnessing a significant transformation, driven by the growing demand for electric vehicles (EVs), renewable energy systems, and stationary applications. Toshiba Corporation has taken a major step forward in this journey by launching its new SCiB module, designed for use in EV buses, electric ships, and stationary applications. This innovative battery module features an aluminium baseplate that significantly enhances heat dissipation, a critical aspect in maintaining battery life.
Challenges in Lithium-Ion Battery Development
Lithium-ion batteries are widely used in various applications, but their high power input and output capabilities come with a significant challenge: managing heat dissipation. Continuous high-power input and output can generate excessive heat within the battery, leading to a reduction in lifespan. Battery developers must strike a balance between heat dissipation and maintaining a long battery life, a task that has become increasingly complex as demand for these batteries grows.
- The use of lithium-ion batteries is diversifying and expanding into new applications, such as electric buses, electric ships, and stationary power systems.
- However, the rapid charging and discharging of these batteries can generate significant heat, threatening battery life.
- Developers must address this challenge by designing batteries that can efficiently manage heat dissipation and maintain battery life while providing high power input and output.
Aluminium, a material commonly used in baseplates, has been chosen for its exceptional thermal conductivity. The new module’s aluminium baseplate dissipates heat at approximately twice the rate of current battery modules, significantly extending battery life. However, aluminium is a conductor, so it must be insulated from the battery cells to prevent electrical shorts.
A Novel Solution: Aluminium Baseplate Design
Toshiba has developed a novel structure that allows the aluminium baseplate to be used while maintaining the necessary voltage resistance. This innovative design enables the module to be certified under the UL1973 safety standard for stationary applications, including off-grid applications and microgrids.
