CR2477 battery

New discovery of high-capacity CR2477 battery

According to foreign media reports, researchers at Shinshu University in Nagano, Japan are developing a thin, high-capacity lithium-ion battery that may open up a new research field for electric vehicle energy storage systems. Zettsu and his colleagues examined the electrical and electrochemical properties of high-voltage (>4.8V, vsLi+/Li) cathodes. Zettsu also used self-assembled monolayers to adjust the surface of the battery, which may become a new research trend. His team coated the cathode surface with ultra-thin fluorosilane, a silicon material that can arrange itself in the most efficient molecular arrangement, transport lithium ions and insulate electrons while retaining one atomic layer. The self-assembled monolayer accumulation coating can reduce the reaction activation barrier during lithium ion transmission. See the text for details.

According to foreign media reports, researchers at Shinshu University in Nagano, Japan are developing a thin, high-capacity lithium-ion battery that may open up a new research field for electric vehicle energy storage systems.

Lithium-ion batteries can store a lot of electrical energy, but their storage capacity will decay as they are used for a longer time. To address this problem, Zettsu and his colleagues examined the electrical and electrochemical properties of high-voltage (>4.8V, vsLi+/Li) cathodes as electrons enter the battery cell from the cathode.

Zettsu also used self-assembled monolayers to adjust the surface of the battery, which may become a new research trend. His team coated the cathode surface with an ultra-thin layer of fluoroalkyl-silane, a silicon material that can arrange itself molecularly in the most efficient way, transport lithium ions and insulate electrons while retaining one atomic layer.

The researchers saw that direct contact between the cathode and the electrolyte was minimized, and the battery capacity did not decay even after hundreds of cycles.
