How tendons buffer energy dissipation by muscle

Tendons are quite resilient springs - they return 90 - 97% of any energy they absorb - so while they can temporarily store energy, this stored energy must be returned. During a movement like walking or running, energy stored in tendon can be used subsequently to drive joint motion and work, but in an activity requiring energy dissipation the ...

How Lithium-ion Batteries Work | Department of Energy

The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
