Episode 348 - More efficient Lithium-Ion batteries and Organic Batteries

We launch from the Nobel Prize for Chemistry 2019 into current battery research and development. Creating the ubiquitous Lithium Ion battery took decades of collaborative research across the globe. How are scientists working together today to make the new generation of batteries? Can we improve LI batteries with new electrolyte mixes? How can we use Silicon instead of graphite in our batteries to give them a boost? Is it possible to make an organic recyclable battery? How can we use proteins and peptides to make organic batteries? Can we make batteries without damaging the environment?

Episode 347 - Capturing carbon with better farms and forests

Capturing carbon is important for helping offset CO2 emissions and tackling climate changes. Farming has an important role to play in improving CO2 sequestration with the use of cover crops and compost. Forests are important carbon sinks too, but they are at risk releasing a lot of the trapped carbon if care is not taken to stop invasive species. Plus fertilisers have helped feed the planet but can leech out nitrogen into the environment, so how do we better manage and improve the nitrogen cycle.
