France's CAC 40 index fell as much as 2.00% intraday.

Researchers at the Institute of Electrical Engineering, Chinese Academy of Sciences proposed a solvation de‑shielding electrolyte design for low‑temperature lithium‑ion capacitors (LICs). The formulation uses gamma‑valerolactone (GVL) as primary solvent (medium polarity, low melting point, moderate Li+ coordination), lithium difluoro(oxalato)borate (LiDFOB) as functional lithium salt, and ethyl acetate (EA) as a weakly coordinating cosolvent to weaken solvent encapsulation of Li+ and encourage anion participation in local solvation structure, creating a weakly bound, anion‑participating solvation environment. Full‑carbon LICs with this electrolyte maintained strong energy output at −40°C, delivering electrode‑mass‑based energy density of 106.8 Wh/kg—about 8.9 times that of conventional carbonate‑based electrolytes. The study reports the approach overcomes slow interfacial reaction kinetics at low temperature caused by strong solvation shielding.

Treasury Secretary Bessent said if Democrats win control of either chamber in the Nov. 3 midterm elections, the Trump administration will seek to push Congress to pass a plan to reduce the federal budget deficit by year-end. He said he is working with OMB Director Vought on a fiscal consolidation plan expected to lower the federal deficit. Bessent added that a Democratic victory would force acceleration of the effort during the lame-duck window between the Nov. 3 election and the Jan. 3, 2027 start of the new Congress, roughly two months.
