Organic Photovoltaics

Batteries are essential everyday life items. They can be found in small and large devices such as flashlights, computers, mobile devices, and automobiles. A battery stores electrical energy in the form of chemical energy and converts that energy into electricity. A typical battery is a collection of one or more cells in which chemical reactions generate electrons that flow in a circuit. Cutting-edge battery technologies with transformative potential include new generation lithium-ion, lithium-sulfur, and solid-state batteries. The Thermo Scientific portfolio includes a variety of products designed to support battery research.

Battery components

Thermo Fisher Scientific offers a wide range of quality products to support battery research, as detailed in our product offerings below.

Anode materials include, among others: natural and artificial graphite, carbon black, fullerenes, lithium foil, oxides of bismuth, germanium, silicon, and tin.

Cathode materials typically include oxides of transition metals that can accommodate lithium by changing their oxidation states.

An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, e.g., water. Electrolytes typically include most soluble acids, bases, and salts.

Pure metals such as aluminum, copper, and nickel and alloys like steel are available in many forms including sheets, wires, ribbons, powders, spheres, and plates.

Conventional electrolytes consist of an organic solvent, e.g., ethylene carbonate, with a dissolved lithium salt.

Interstitial materials are used for the control of thermal conductance. They include carbonate and other solvents, lithium ions (e.g., PF6-, BF4-, CO32-), polyethylene, polypropylene, and other polymers in sheets or powder form.

Binders are inert materials that hold the active material particles within the electrode of a battery together to maintain a strong connection between the electrode and the contacts.
