美國總統特朗普：我們已經在北約投資，盟友應該願意提供幫助。

At a July 7 regular briefing the foreign ministry said the navy’s submarine-launched strategic missile test was routine military training, not directed at any specific country or target. Beijing said it had notified the Solomon Islands and other South Pacific states and relevant parties in advance, that the activity complied with international law and practice, and reiterated China adheres to a defensive nuclear strategy and maintains its nuclear forces at the minimum level necessary for national security, urging others not to over-interpret.

Cambridge University researchers say applying a steady physical pressure of about 12.5 bar can roughly double lithium‑ion cell life in lab tests; pressure above that promotes lithium plating on the anode, while too little pressure causes cathode cracking, both accelerating degradation. Authors say the method could extend EV battery service life, reduce battery scrappage and recycling strain, and lower demand for critical minerals such as nickel and cobalt — implications for mining supply, EV residual values and used‑car market dynamics.
