Abstract: A gamepad and a joystick feedback force apparatus thereof are disclosed. The joystick feedback force apparatus comprises a joystick that is configured to accept a user's operation and is rotatably installed in a casing of the gamepad. It further comprises a torque output device and a deceleration device. An output shaft of the torque output device is connected with an input end of the deceleration device, an output end of the deceleration device is connected with a rotating shaft of the joystick to apply a torque output by the torque output device to the rotating shaft. When the user operates the joystick to rotate, a certain torque is applied to the rotating shaft after being decelerated by the deceleration device, namely, the corresponding torque is applied to the joystick to form a feedback force to the user.

Abstract: The present invention relates to metal ion salts which can be used in electrolytes for producing electrochemical devices, including both primary and secondary batteries, photoelectrochemical cells and electrochromic displays. The salts have a low energy of dissociation and may be dissolved in a suitable polymer to produce a polymer solid electrolyte or in a polar aprotic liquid solvent to produce a liquid electrolyte. The anion of the salts may be covalently attached to polymer backbones to produce polymer solid electrolytes with exclusive cation conductivity.
