Taiwan makes 10 million mask a day with only a $6.6 million investment in public money while securing 3 masks a week for each resident at less than $1 for 3 masks. Taiwan has done this with a health care system that cost about $30 a month in insurance cost for its citizens yet is one nation with the fewest death per capita from the coronavirus. With the highest health care cost per capita in the world, the US health care easily cost each resident $1,000 a month, yet is unable to provide basic PPE for its healthcare workers or masks for its residents. You have to wonder where all the money is going.
The BBC article explained it this way: 'Since hybrid cars have two power sources - electric and petrol or diesel - the catalytic converter is used less frequently to process pollutants. The metals are less likely to corrode, meaning they are worth more and thus attractive to thieves.'
Oxis: 'we aim to double the current cycle life to achieve upwards of 500 cycles.' This number is still quite low compared to the new B4C-ACF substrate-based battery that could be stably operated for 3,000 cycles with a high coulombic efficiency of 99.24% - as reported here earlier:
Another group at Georgia Tech had already published a similar finding on December 10, 2014: In Situ Formation of Protective Coatings on Sulfur Cathodes in Lithium Batteries with LiFSI-Based Organic Electrolytes. Adv. Energy Mater. 2014. DOI: 10.1002/aenm.201401792 Gleb Yushin, Georgia Institute of Technology, Atlanta, USA, and colleagues used a solution of lithium bis(fluorosulfonyl)imide salt (LiFSI) in dimethoxyethan (DME) as an electrolyte for Li-S batteries. This electrolyte leads to a cathode mass loss of only 23 % after 1000 cycles and a high average coulombic effectiveness of nearly 100 %.
