Week 20-26 May 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.
Study of metal-oxide battery degradation
A team of scientists from several US and Canadian institutions has studied the degradation of an iron-oxide-based Li-ion battery over 100 charge-discharge cycles. They provide an explanation for the processes that lead to loss of capacity. This knowledge will be useful to researchers looking for ways to improve the durability of Li-ion batteries.
Impact areas: Li-ion battery durability
High-performance textile battery
Researchers from the Hong Kong Polytechnic University have developed "a highly flexible, high-energy Textile Lithium Battery" with energy density of "more than 450 Wh/L, and excellent flexibility — with a bending radius of less than 1mm, and foldability of over 1,000 cycles with marginal capacity degradation."
Impact areas: Flexible batteries, Wearables
Magnesium-based redox battery
Scientists from the Tokyo University of Science are proposing to use "cobalt-substituted MgNiO2" as battery cathode. According to the researchers, "Novel magnesium secondary batteries have the potential to surpass and replace lithium ion batteries as high-energy density secondary batteries."
Impact areas: Magnesium batteries
Study of fullerene-based materials as anodes for lithium ion batteries
Researchers from several Singapore, Chinese and Canadian research institutions have studied the performance of several fullerene-based materials as Li-ion battery anodes.
Impact areas: Li-ion battery research
Study of plastic crystals as battery electrolytes
Scientists from the University of Augsburg have studied several plastic-crystalline electrolytes for solid-state batteries and have identified the factors "essential for the development of mixed [plastic crystal] electrolytes for future electrochemical applications."
Impact areas: Solid state electrolyte research
