Interpretation of lithium batteries emit heat into electrical energy

Although the processor, storage, data network and other aspects of electronic consumer products have been improving, only battery technology has stagnated. At present, the lithium battery is still the most important type of battery, fuel, solar cells are still in development, and other new materials such as graphene are in the ascendant. Of course, the research and development of new battery technologies have not stopped. Recently, researchers at Stanford University in the US have come up with a new method that can convert the heat emitted by the battery itself into electricity, which can be regarded as a very interesting concept.

In general, battery-powered devices will dissipate heat during use. This part of the energy is actually wasted. Based on the principle of thermoelectricity, the heat emitted by the device can be collected and stored in another rechargeable battery to provide additional power to the device. Obviously, this kind of technology sounds very promising. On the one hand, the application form of smart phones will emit a lot of heat; on the other hand, this technology does not require replacing the battery material, and only an effective energy conversion device can be integrated.
