Canada has made biodegradable batteries from trees
Researchers at the University of British Columbia have created a biodegradable battery using tree trunks and zinc, offering an eco-friendly alternative to harmful lithium-ion batteries.
Eco-friendly batteries decompose in months without leaving harmful chemicals, making them perfect for medical implants, wearable devices, and environmental sensors.
The batteries will reduce the growing e-waste crisis by being made from sustainable materials, completely dissolving and producing zero waste. They are particularly suitable for short-lived electronics.
The innovation shows promise for a cleaner future in green technology, but its scalability and energy capacity for broader use are still under investigation.
The batteries are flexible, light, and charge quickly, like paper. Unlike lithium batteries that degrade over time and need rare metals, these wood-based cells break down in the soil within 60 days. They don’t catch fire, don’t leak toxins, and can even be made using pulp waste from existing lumber mills.
The University of British Columbia team has powered LED devices and drones with a new battery format. This affordable, renewable, and scalable material could transform energy storage for wearables and low-power devices.
Companies in Canada are already testing scaled-up versions for sensors, electric watches, and even biodegradable GPS trackers.
