Maximilian Fichtner (born 1961 in Heidelberg, Germany) is professor for Solid State Chemistry at the Ulm University and executive director of the Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU).
Fichtner was educated in Food Chemistry and Chemistry at the University Karlsruhe, now Karlsruhe Institute of Technology where he was awarded by the Diploma in Chemistry. In 1992 he received the Ph.D. in Chemistry/Surface Science with distinction and the Hermann Billing Award [1] for his thesis. In the thesis he developed a novel method for a spatially resolved speciation of beam-sensitive salts by SIMS. With the method he analysed the surface composition of atmospheric salt aerosol particles and contributed to the current climate model.
Following his PhD, Fichtner spent two years as a young researcher at the former Karlsruhe Nuclear Research Center (KfK) and developed his method further so that it could be applied to organic materials also. In 1994 he became assistant to the board of directors of the Karlsruhe Research Center (FZK), in the area Basic Research and New Technologies, with Herbert Gleiter as director. In 1997 he left to build up a new activity on microprocess engineering, with a focus on heterogeneous catalysis in microchannels, for fuel processing (methanol steam reforming, partial oxidation of methane) and synthesis of chemicals. The group was eventually integrated in the new Institute for Microprocess Engineering in 2001. In 2000 he was offered a position at the new Institute of Nanotechnology, INT [2] (Founding directors: Herbert Gleiter, Jean-Marie-Lehn, Dieter Fenske) to build up a new activity on nanoscale materials for energy storage. Since then he is group leader there. In 2012 he received a call by the Ulm University to become a professor (W3) in Solid State Chemistry, which he accepted in 2013. The position is connected to a function as group leader at the new Helmholtz Institute Ulm. Since 2015 he has been executive director of the institute.
Fichtner has co-ordinated several EU projects and collaborative projects from the German ministries of Economy and Research and Education. He has been organizer of various symposia at MRS and GRC conferences, and he was Chair of the GORDON Research Conference on Metal-Hydrogen Systems in 2013 [3] and of the 1st International Symposium on Magnesium Batteries (MagBatt) in 2016. [4]
In his career Fichtner worked on various topics, covering Theoretical Chemistry, Instrumental Analysis, Higher Administration, Chemical Engineering, Heterogeneous Catalysis, Hydrogen Storage, Electrochemistry and Battery Research.
Pioneering achievements were the first measurements of salts with Secondary Neutral Mass Spectrometry, [5] the development of a depth-resolved speciation of beam sensitive salts, a microstructure reactor which could safely burn and transfer the heat from a stoichiometric hydrogen-oxygen mixture to a thermo oil, thus demonstrating the enormous capability of running dangerous reactions in microstructure reactors safely. [6]
In the development of hydrogen storage materials, new complex hydride compounds were synthesized and investigated, [7] [8] the fasted charge and discharge of an aluminum hydride to date by a new Ti13 catalyst, first applied for that purpose by the Bogdanovig group of Max Planck Mülheim, was independently confirmed. [9] Further work in this area was focused on elucidating nanoscale effects in energy materials [10] [11] and studies, based on pioneering work since the late 1990s by various groups from all over the world on hydrogen and the effects by nanostructures, of the change of thermodynamic properties of complex hydrides was conducted in his group. [12]
In battery research, new synthesis methods were developed to stabilize conversion materials, [13] [14] new types of batteries based on anionic shuttles were presented [15] [16] and new electrolytes were developed for magnesium properties with outstanding voltage windows and non-nucleophilic properties, [17] making reversible Mg-S cells possible. Moreover, a new class of cathode materials is being studied with the highest packing densities for Li ions to date, the so-called Li-excess disordered rocksalt materials (DRX), developed by the Gerbrand Ceder group. [18]
Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li[AlH4] or LiAlH4. It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for hydrogen storage.
Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid that transitions to white with decreasing crystal size. Its structure is analogous to that of sodium chloride, but it is much less soluble in water. It is mainly used as a component of molten salts. Partly because Li and F are both light elements, and partly because F2 is highly reactive, formation of LiF from the elements releases one of the highest energies per mass of reactants, second only to that of BeO.
Several methods exist for storing hydrogen. These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of ammonia. For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H2: it boils around 20.268 K (−252.882 °C or −423.188 °F). Achieving such low temperatures requires expending significant energy.
Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.
As the world's energy demand continues to grow, the development of more efficient and sustainable technologies for generating and storing energy is becoming increasingly important. According to Dr. Wade Adams from Rice University, energy will be the most pressing problem facing humanity in the next 50 years and nanotechnology has potential to solve this issue. Nanotechnology, a relatively new field of science and engineering, has shown promise to have a significant impact on the energy industry. Nanotechnology is defined as any technology that contains particles with one dimension under 100 nanometers in length. For scale, a single virus particle is about 100 nanometers wide.
Magnesium hydride is the chemical compound with the molecular formula MgH2. It contains 7.66% by weight of hydrogen and has been studied as a potential hydrogen storage medium.
A metal–air electrochemical cell is an electrochemical cell that uses an anode made from pure metal and an external cathode of ambient air, typically with an aqueous or aprotic electrolyte.
Sodium-ion batteries (NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na+) as their charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion. Sodium belongs to the same group in the periodic table as lithium and thus has similar chemical properties. However, in some cases, such as aqueous batteries, SIBs can be quite different from LIBs.
NASICON is an acronym for sodium (Na) super ionic conductor, which usually refers to a family of solids with the chemical formula Na1+xZr2SixP3−xO12, 0 < x < 3. In a broader sense, it is also used for similar compounds where Na, Zr and/or Si are replaced by isovalent elements. NASICON compounds have high ionic conductivities, on the order of 10−3 S/cm, which rival those of liquid electrolytes. They are caused by hopping of Na ions among interstitial sites of the NASICON crystal lattice.
A magnesium sulfur battery is a rechargeable battery that uses magnesium ion as its charge carrier, magnesium metal as anode and sulfur as cathode. To increase the electronic conductivity of cathode, sulfur is usually mixed with carbon to form a cathode composite. Magnesium sulfur battery is an emerging energy storage technology and now is still in the stage of research. It is of great interest since in theory the Mg/S chemistry can provide 1722 Wh/kg energy density with a voltage at ~1.7 V.
Magnesium batteries are batteries that utilize magnesium cations as charge carriers and possibly in the anode in electrochemical cells. Both non-rechargeable primary cell and rechargeable secondary cell chemistries have been investigated. Magnesium primary cell batteries have been commercialised and have found use as reserve and general use batteries.

Calcium (ion) batteries are energy storage and delivery technologies (i.e., electro–chemical energy storage) that employ calcium ions (cations), Ca2+, as the active charge carrier. Calcium (ion) batteries remain an active area of research, with studies and work persisting in the discovery and development of electrodes and electrolytes that enable stable, long-term battery operation. Calcium batteries are rapidly emerging as a recognized alternative to Li-ion technology due to their similar performance, significantly greater abundance, and lower cost.
The inorganic imide is an inorganic chemical compound containing
A silanide is a chemical compound containing an anionic silicon(IV) centre, the parent ion being SiH−3. The hydrogen atoms can also be substituted to produce more complex derivative anions such as tris(trimethylsilyl)silanide (hypersilyl), tris(tert-butyl)silanide, tris(pentafluoroethyl)silanide, or triphenylsilanide. The simple silanide ion can also be called trihydridosilanide or silyl hydride.
Fluoride batteries are rechargeable battery technology based on the shuttle of fluoride, the anion of fluorine, as ionic charge carriers.
Fluorohydride salts are ionic compounds containing a mixture of fluoride and hydride anions, generally with strongly electropositive metal cations. Unlike other types of mixed hydrides such as oxyhydrides, fluorohydride salts are typically solid solutions because of the similar sizes and identical charges of fluoride and hydride ions.
