The electric vehicle segment is growing worldwide every year. In search of a sustainable solution for electric vehicle batteries, scientists are looking for options to manufacture batteries, and lignin is present in trees is a strong candidate for sustainable fast-charging electric battery.

The Finnish company Stora Enso is committed to innovation and revolution and is exploring ways to create electric batteries with lignin from trees that can be Charges up to eight minutes. As EV sales grow, Stora Enso is investing in sustainable solutions for the EV segment.

from lignin, Stora Enso has created Lignode, a hard carbon compound.. Lauri Lehtonen, Head of Innovation at Stora Enso, explains Lignina’s potential for electric batteries. “Lignin is the glue for trees, it sort of sticks the cellulose fibers together and also makes the trees very tough.” The organic compound is a polymer and contains carbon and has proven to be a high quality compound for battery production.

The production of electric batteries from lignin should start in 2025.

The company has entered into a partnership agreement with the Swedish company Northvolt and plans to begin mass production of batteries in 2025. Secondly, the demand for electric batteries will continue to grow exponentially in the coming years, and a sustainable solution becomes necessary.

OUR The lignode works like the carbon anode of a battery., but so far Stora Enso has not explained in more detail how the process of turning lignin into a rigid carbon structure works. According to Lehtonen, lignode is an amorphous structure. “This allows for much greater mobility in and out of the ions.” The connection structure will help in the production of lithium ion or sodium batteries capable of charging in eight minutes, which is highly desirable in the electric vehicle segment.

In addition, researcher Chelsea Baldino of the International Clean Transportation Council argues that if the lignin used is recovered as a by-product of the paper-making process, no more trees would need to be cut down to make batteries., which is necessary for a battery to be considered stable. It remains to be seen whether lignin-derived batteries will ever be able to replace the graphite found in traditional battery anodes.
