Solid electrolyte forms in place for better Li batteries

A solid electrolyte that only forms once its liquid precursors are in intimate contact with electrode material is mooted as a step towards all-solid lithium batteries by Cornell University. Intimate contact – inherent with liquid electrolytes – is needed to achieve high lithium ion throughput and low series resistance. “The key insight is the introduction ...

12 inch foundry hit hard

Q1 foundry revenue will be down 16% on Q1 2018, says TrendForce, to reach $14?6 billion. Negative forces in Q1 have been the seasonal effect, weakening demand for consumer products, high inventory levels, falling demand in the car market, the Intel CPU shortage, the slowing of China’s economic growth and the US-China trade dispute. Q1 ...
