In solid-state lithium-ion battery cells, electrolyte-infiltrated composite electrode includes an electrolyte component consisting of polymer matrix with ceramic nanoparticles embedded in the matrix to form networking structure of electrolyte. The networking structure establishes effective lithium-ion transport pathway in the electrode. Electrolyte-infiltrated composite electrode sheets and solid electrolyte membranes can be used in all solid-state lithium electrochemical pouch and coin cells. Solid-state lithium-ion battery is fabricated by: (a) providing an anode layer; (b) providing a cathode layer; (c) positioning a ceramic-polymer composite electrolyte membrane between the anode layer and the cathode layer to form a laminar battery assembly; (d) applying pressure to the laminar battery assembly; and (e) heating the laminar battery assembly. Pressure-aided co-curing strengthens the contacts between the electrodes and the solid electrolyte membrane thus creating stable electrode-membrane interfaces with fewer porous regions. Lithium electrochemical cells and batteries exhibit excellent rate performance and outstanding stability over wide temperature range.

A photovoltaic (PV) cell health monitoring apparatus includes a Radio Frequency Identification (RFID) tag mounted to the PV cell and having identifying information of the PV cell, and a sensor in communication with the RFID tag for measuring health information of the PV cell.

A dust sensor in the form of a comb-like electrode array measures electrical capacitance as an indication of an amount of dust on an exposed surface of the PV cell. An RFID tag antenna arranged as a meander-line patch antenna covered with polyethylene has a dual function as a temperature sensor.
