Batt-trees? Cellulose in solid-state batteries shows promise

Solid-state lithium-ion batteries are a hallowed goal in energy: they’d be more powerful – and safer – than current commercial liquid-based models. But researchers are still looking for solid materials that can conduct electricity well and integrate with the rest of the battery. One such substance has been found by a team of US materials … Continue reading Batt-trees? Cellulose in solid-state batteries shows promise

Lithium: Powering the Green Revolution

by Richard A Lovett As the climate warms, sea levels rise and droughts, heatwaves and bushfires multiply, the need to usher in the green-energy future is increasingly urgent. But that doesn’t mean it can be done without significant challenges – not just in the economy (as it makes the changeover), but technologically and scientifically as … Continue reading Lithium: Powering the Green Revolution

Predicting the life and death of batteries

Estimating battery life is one of the great modern dilemmas, and the older the item, the harder it gets. But researchers at Stanford University, US, may be about to save us all. They’ve developed a model they say can predict the true condition of a rechargeable battery in real-time. The algorithm combines sensor data with … Continue reading Predicting the life and death of batteries

Exploring potential of solar-flow batteries

Scientists continue to advance the potential to use solar-flow batteries to provide electricity in remote areas. An international team of chemists and solar cell researchers reports in the journal Nature Materials that it has developed a single device that contains both a solar cell to convert sunlight into electricity and chemicals that can store the … Continue reading Exploring potential of solar-flow batteries

Can cabbage make batteries greener?

As the world works to reduce greenhouse gas emissions, interest in electric vehicles is increasing. This, along with the steady demand for new smartphones, computers and other electronic gadgets, is leading to an increased need for lithium-ion batteries — and, thus, lithium as well. Traditional mineral extraction comes with a slew of issues, both environmental … Continue reading Can cabbage make batteries greener?

New research to make better batteries

The quest for a better battery is engaging a lot of scientific minds, but it’s not often three advances are reported at pretty well the same time. Two from the US address the challenge of making next-gen lithium batteries more commercially viable, while the third, from the UK, uses MRI in a novel way. In … Continue reading New research to make better batteries
