BTRY raises $5.7 million to industrialize ultra-thin solid-state cells

by

Swiss battery start-up BTRY has raised $5.7 million in an oversubscribed seed round.

The funds will accelerate the industrialization of its ultra-thin solid-state batteries – a new category of energy storage combining fast charging, extreme temperature stability, and intrinsic safety in one of the world’s thinnest formats.

They power next-generation devices such as connected labels, wireless sensors, and wearables – applications where conventional batteries could not fit or endure. [Read more…] about BTRY raises $5.7 million to industrialize ultra-thin solid-state cells

A novel mathematical framework unlocks unlimited customization of full concentration gradient in high-nickel cathodes for improved safety and stability

High-nickel cathodes are promising for improving the energy density of lithium-ion batteries (LIBs). However, their high nickel concentration leads to intense side reactions, degrading safety and stability. While full concentration gradient (FCG) design can address this issue, current approaches limit design flexibility.

Now, researchers have developed a novel mathematical framework that, combined with an automated reactor system, allows unlimited customization of FCGs with independent parameter control, leading to LIBs with enhanced safety and stability.

With the recent global push toward renewable energy and electric vehicles, the demand for lithium-ion batteries (LIBs) is rising rapidly. The performance and stability of LIBs largely depend on the cathode material, which can account for nearly 40-45 percent of the total battery cost.

Researchers say they have developed a graphene coating that ‘supercharges zinc-ion batteries for grid use’

Zinc-ion batteries are promising for energy storage, but their traditional current collectors suffer from scalability issues, restricting industrial applications.

In a recent study, researchers from Dongguk University, South Korea have designed a novel alternative current collector in the form of graphene-coated stainless-steel foil.

Consequently, they achieve batteries with high electrochemical performance and superior cycling stability, potentially paving the way for industrial-scale systems.

The present century has witnessed a proactive shift towards more sustainable forms of energy, including renewable resources such as solar power, wind, nuclear energy, and geothermal energy. [Read more…] about Scientists develop ‘supercharging technology’ for batteries using graphene
