Week 4-10 March 2019
Welcome to the new edition of our Last Week In Batteries digest!
This weekly digest of developments in the battery space is intended as a demonstration of what one can do with Avogadro One. Avogadro One allows capturing relevant news easily and quickly, saving you valuable time. If you want to know when you can use Avogadro One for your own research, please sign up to our mailing list here. We would also be happy to hear any feedback.
This is a very basic review of last week's events relevant to the battery and fuel cell industries. We do not pretend to be experts in this space but as investors we find such an overview helpful. The digest is intentionally very brief and dry and is intended as a demonstration rather as an end product. We'd love to hear what tools/software/platforms you use to stay abreast of the events in your industries of interest: please answer our anonymous questionnaire.
A study of lithium's interaction with bilayer graphene
A team of scientists from Fujian Normal University and Fujian Provincial Collaborative Innovation Center for Optoelectronic Semiconductors and Efficient Devices have published a study of lithium diffusion within bilayer graphene. They conclude that bilayer graphene could be a good anode material for Li-ion batteries.
Impact areas: Li-ion battery performance
Battery electrodes made from coffee grounds
RUDN researchers have made battery electrodes from coffee grounds. The process was rather energy-intensive but serves as a proof of concept, showing that it is possible to make Li-ion battery electrodes from organic waste.
Impact areas: Li-ion battery supply chains and environmental footprint
Optimal battery energy storage placement for voltage stability
Researchers from GEIRI North America and Aalborg University have proposed a simulation-based approach to select the optimal placement of multiple Battery Energy Storage System (BESS) units to alleviate transient voltage instability.
Impact areas: Utility-scale energy storage
Multi-dimensional simulations of zinc-air batteries
Scientists from several German institutions have published "the first multi-dimensional simulations of zinc-air batteries." The simulations look at the factors that limit the shelf-life and cycle-life of zinc-air batteries. The researchers "optimize initial anode structure and charge-discharge protocols for improved performance and cycle-ability."
Impact areas: Zinc-air battery durability and performance
