Storage
Methane as an energy store
Researchers at PSI and the start-up AlphaSYNT are working together on a solution for efficiently storing energy.
Movie directors with extra roles
Data storage devices based on novel materials are expected to make it possible to record information in a smaller space, at higher speed, and with greater energy efficiency than ever before. Movies shot with the X-ray laser show what happens inside potential new storage media, as well as how the processes by which the material switches between two states can be optimised.
Power on demand
If photovoltaic or wind power plants produce more electricity than the network can absorb, valuable energy is lost. At the ESI Platform, PSI researchers are investigating how fuel cells can contribute to making this energy usable in a targeted way through storage.
Nanomaterial helps store solar energy: efficiently and inexpensively
Efficient electrolysers are needed in order to store sun and wind energy in the form of hydrogen. Thanks to a new material developed by researchers at the Paul Scherrer Institute PSI and Empa, these devices are likely to become less costly and more efficient in the future. Researchers were also able to demonstrate that this new material can be reliably produced in large quantities, showing its performance capability in an electrolysis cell—the main component of an electrolyser.
Water pathways make fuel cells more efficient
Researchers from the Paul Scherrer Institute (PSI) have developed a coating technique in the laboratory conditions that could raise the efficiency of fuel cells. The PSI scientists have already applied to patent the technique, which is suitable for mass production.
Why lithium-ion-batteries fail
Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH and PSI scientists have quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.
Towards sodium ion batteries – understanding sodium dynamics on a microscopic level
Understanding sodium dynamics on a microscopic levelLithium ion batteries are highly efficient, But there are drawbacks to the use of lithium: it is expensive and its extraction rather harmful to the environment. One possible alternative might be to substitute lithium with sodium. To be able to develop sodium-based batteries, it is crucial to understand how sodium ions move in the relevant materials. Now, for the first time, scientists at the Paul Scherrer Institute PSI have determined the paths along which sodium ions move in a prospective battery material. With these results, one can now start to think of new and specific ways to manipulate the materials through slight changes to their structure or composition, for example à and thereby achieve the optimized material properties necessary for use in future batteries.
A new generation of lithium batteries is approaching industrial implementation
Lithium-ion batteries are one of today's best technologies for storing electrochemical energy. They have a high energy density and specific energy and a sufficiently long lifetime to allow them to be used in microelectronic devices and cars. The commercial rise of Li-ion batteries in the last two decades is impressive. However, further improvements are possible and this is a field in which researchers at the Paul Scherrer Institute (PSI) are working. Nevertheless, the potential of the Li-ion battery is limited chemically and it will only be possible to achieve an even higher energy density, which is crucial for electric mobility in particular, by using other new types of batteries.
