“We’ve found out that wood-derived cellulose is a super ion conductor material, making it ideal for use in a new generation of solid state batteries,” says Liangbing Hu, Herbert Rabin Distinguished Professor at the Department of Materials Science and Engineering, University of Maryland.
Put simply, it means this material could in theory be used in super powerful batteries without increasing battery size or weight. This could have major benefits for manufacturing power-hungry machines and devices where weight and size are a factor, such as vehicles.
“There is an urgent need for super-ion-conducting, solid-state electrolyte for developing safe and fast-charging electric vehicles. Our work – and that of others working in the field – will be of great benefit to the community,” Hu says.
UPM’s wooden satellite awaits its launch: If something can handle space, It can handle pretty much anything
When wood was first used to create seafaring vessels, it would have been impossible to conceive of it forming the basis of craft that would one day fly high above the clouds. Turn the clock forward and this is exactly what UPM is doing with an actual, wood-based satellite.
Wood products aren’t just being used at the micro level for things like chips and batteries, but they’re also heading where no wood has gone before – space.
Arctic Astronautics, a Finnish space tech company, has developed a wood-based nano satellite called WISA Woodsat. The structure is made of UPM’s WISA Plywood. The current outlook is to launch a real satellite in 2023. It will fly at 550 kilometer orbit at a speed of 27 000 kilometers per hour, explains Ari Voutilainen, Director of stakeholder relations at UPM Plywood.
“As a material science company we do know quite a bit about wood and its characteristics in different environments,” Voutilainen begins.
“We do have a hypothesis on some of the behaviour but nothing beats a long-term real world test. Space has many similar environmental conditions as the Earth’s surface but some of them are amplified. Heat and cold are okay, but UV and other radiation levels are much higher outside the Earth’s atmosphere.”
The satellite has been fully functional now for a year, but is currently waiting for space operation permits both from Finland and New Zealand, where it will be launched. A spacefaring wooden craft would have big implications for how consumers and industry think about wood in wider industrial use. If something can handle space, it can pretty much handle anything.
