An all solid state lithium ion battery (SSLIB) has an advantage in electrical capacity compared to the popular lithium ion battery (LIB) using a liquid electrolyte. However, a...

The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent...

Here we propose a u+SR investigation on the solid solution Cax-1NaxCr2O4, a Q1D zigzag chain compound where Na+ ions are allocated in the hexagonal one-dimensional channels...

This experiment will probe the evolution of magnetic ordering in Sr2Cr3As2O3, a compound containing Cr3+ moments in Cr2O square layers and Cr2+ moments in CrO2 layers. We will...

In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive...

We would like to propose a continuation experiment on Li-ion battery cathode material, Li(Ni,Co)O2. In previous experiments in 2013 and 2014, we attempted muSR technique to...

Hydrogen storage is a significant area of energy materials research and there have been extensive efforts into the discovery and development of lightweight materials. Although...

We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu...

Research on positive insertion electrodes for high performance batteries has seen immense interest in fluoride containing compounds, since higher operating potentials can be...

Fuel-cell cars are expected to be an ultimate solution for accommodating clean environments with convenient personal transport system. In order to make fuel-cell cars more...

With increasing demands for high performance/capacity rechargeable batteries the materials science community is currently facing two severe issues. First of all there is from a...

Lithium-excess cathode materials can deliver high capacity and lead to high energy density. Lithium-excess cathode materials are categorized as “ordered” and “disordered” on the...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

When we know an intrinsic diffusion coefficient of Li-ion (D) in an ionic conductor, we could estimate a number of mobile Li ions, i.e. carrier density (n), from ionic...

LiFePO4 (LFP) is a commercially applied cathode material for lithium ion batteries. With its Li ion hopping predominantly occurring along one-dimensional channels, LFP is a very...

In order to estimate a reliable reaction area (a_r) between cathode and liquid electrolyte in a Li-ion battery, we wish to propose a muSR experiment on a charged-state cathode...

This proposal describes a continuation muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing...
