Nope! Lithium polymer batteries are substantially different from lithium ion. Each generation of lithium batteries is a pretty unique chemistry, the only thing that stays constant is the use of lithium as the cathode. Electrolyte, anode, and interface chemistry actually progresses pretty quickly.
Also, for drastically different battery chemistries which have been commercialized, see sodium ion batteries, and to a lesser extent NaS/ZEBRA batteries.

I assumed that Linux was not really under the control of the US, but I guess the Foundation is incoporated in the US as a 501©(6) and the kernel org itself is a 501©(3), so that does give Congress more levers on the kernel than I expected.
Not to mention that most (all?) of the major corporate funders of the kernel are US-based…
I really hope the kernel doesnt get (geo)politicized.
Edit: based on @RobotToaster’s link, yeah it looks like every major “employer” contributor to the kernel other than Huawei, Linaro, Arm, and Suse are American. Arm is probably working mostly on support for its architecture, so I guess it’s Linaro (UK) and Suse(DE).
That’s not to downplay the role of independent contributors, but it seems like a good indicator of the “power of the purse strings”.
Edit 2: here’s a more recent set of development statistics from LWN. Looks like the ordering has changed quite a bit since 2022, or it varies a lot with each kernel version
At least according to Wikipedia, small amounts of carbon (< 2.14%) in the final alloy are an important component in controlling the ductility, which agrees with what I thought I remembered from materials classes (although I am not a materials scientist). Obviously not using the Bessemer process drastically reduces the amount of carbon necessary, but trace carbon is important.
Designed in the US, fabbed at TSMC in Taiwan. TSMC is opening some n-1 fabs in Arizona soon so some could be fabbed in the US in the future.
