Really excited to hear your response. Thank you
You can convert phones to wireless charging, it's all the same thing, wireless charging is nothing more than 2 coils transferring electricity wirelessly. Considering bottom of most mice is plastic you don't have to cut the bottom either unlike metal phones that need to have the place/part under coil swapped to plastic. There are endless small batteries on hobby sites such as hobbyking.
I see others linked some similar chargers to what I saw. But in a larger more standalone package.
You don't need a 24/7 charging, you can do a parking spot under your mat for the night, etc. What to keep in mind is how the charging will affect rest of the device.
If you can charge on whole pad and enough while in use, then yes you could potentially only use a large capacitor but then batteries aren't that much heavier either and often smaller at higher capacity. Capacitors are good for high currents. Batteries for low currents and storage, which is what you need.
