Nuclear batteries began in 1913, when Henry Moseley first demonstrated a current generated by charged-particle radiation. In the 1950s and 1960s, this field of research got much attention for applications requiring long-life power sources for spacecraft. In 1954, RCA researched a small atomic battery for small radio receivers and hearing aids. [4]
Betacel is considered to be the first commercially successful betavoltaic battery. [1] [2] [3] It was developed in the early 1970s by Larry C. Olsen at the American corporation McDonnell Douglas, using the radioisotope Promethium-147 as the beta-electron source coupled to silicon semiconductor cells.
A betavoltaic device (betavoltaic cell or betavoltaic battery) is a type of nuclear battery that generates electric current from beta particles emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium.
A solid-state silicon battery or silicon-anode all-solid-state battery is a type of rechargeable lithium-ion battery consisting of a solid electrolyte, solid cathode, and silicon-based solid anode. [1] [2] In solid-state silicon batteries, lithium ions travel through a solid electrolyte from a positive cathode to a negative silicon anode. While ...
The specific capacity of silicon is approximately ten times greater than carbon. The atomic radius of Si is 1.46 angstroms, while the atomic radius of Li is 2.05 angstroms. The formation of Li 3.75 Si causes significant volumetric expansion, progressively destroying the anode. [3]
Citizen's watches use lithium-ion batteries to store sufficient energy to power the watch for up to five years without light exposure, [3] by allowing the watch to enter a power-saving or hibernation mode during which the seconds hand stops until the watch is re-exposed to light. Not all have a power-save mode, yet will still hold a charge for ...
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.
A simple betaphotovoltaic nuclear battery can be constructed from readily-available tritium vials (tritium-filled glass tubes coated with a radioluminescent phosphor) and solar cells. [5] [6] [7] One design featuring 14 22.5x3mm tritium vials produced 1.23 microwatts at a maximum powerpoint of 1.6 volts. [5]
