The demand for efficient energy storage solutions is expected to increase significantly in the coming years. More sustainable energy systems are expected to require a transition to electrification. LIB’s are considered to be one of the most important energy storage technologies.
Battery development is considered to be a key component of an electric future and batteries are a key focus for engineering research. As the energy density of batteries increases, battery safety becomes even more critical. LIB’s contain a flammable electrolyte that has led to explosions and fires if damaged or incorrectly charged.
Ahlstrom-Munksjö’s fiber-based material is used as a separator in an innovation that withstands temperature elevation on the inside of a battery that ultimately causes fire and explosion accidents of LIB’s.
The safety challenge of the Lithium-ion cell could be solved by using a fiber-based separator. The fiber-based separator is thermally stable and hence solves the safety challenge at its core. The solution is expected to provide the same electrical protection as a fuse on the inside of each battery.
Ahlstrom-Munksjö’s fiber-based nonwoven material uses Soteria Battery Innovation Group technology as a Lithium-ion cell separator to withstand temperature elevation inside of a battery. The differentiating product, currently being developed, could enable a safe and light architecture for Lithium-ion batteries.
Ahlstrom-Munksjö believes that a more sustainable everyday life is enabled by smart fiber-based solutions.
