“…Li is widely used to store energy, particularly in batteries [ 265 , 266 , 267 , 268 ] and capacitors [ 269 , 270 ], and we foresee nanogenerators [ 271 ] (including stimuli-responsive nanogenerators, e.g., photoactivatable nanogenerators [ 272 ]) will have broad applications in medical fields, such as regenerative medicine, rehabilitation, and cancer treatment [ 273 , 274 , 275 , 276 ], particularly as nanogenerators have been shown to increase the efficacy of chemoimmunotherapy for non-small-cell lung cancer [ 277 ]. Therefore, Li-doped bioceramics may be good candidates for nanogenerators for advanced multifunctional systems in cancer treatments and regenerative medicine [ 272 , 278 ].…”
