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 ...

APEC: TI thinks laterally to make ac-dc chip with 15mW stand-by

Texas Instruments has used everything except the standard inductive step-down solution to make an ac-dc power supply with 10mW no-load performance, and 15mW light load drain (150nF mains series cap). “This device achieves the best balance between high efficiency and ultra-low noise while shrinking power-supply size, it claims, with some justification – although it does ...
