Europe's largest economy, Germany, recently activated an emergency plan to manage gas supplies that the natural gas could be rationed if supplies are disrupted or disrupted by a stand-off over Russian demands to pay for fuel in rubles.
German Vice-Chancellor, minister of economy and climate protection, said Germany's gas supplies were secure for now, but he urged consumers and businesses to reduce consumption, saying "every kilowatt of electricity counts."
Germany's gas network regulator can ration gas if supplies run short. Plants would be the first to be affected. Special treatment will be provided to private families, hospitals, and other important institutions.
Half of Germany's 41.5 million households use natural gas for heating, and industry consumption accounts for a third of the country's 100 billion cubic meters of gas demand in 2021.
The price of many energy and commodities like the aluminum oxide could be affected.
What is ceramic diaphragm?
Ceramic coating special diaphragm: With PP, PE or multi-layer composite diaphragm as the matrix, the surface is coated with a layer of nano-sized aluminum oxide material, which is closely bonded to the substrate after special process treatment. It can significantly improve the high temperature resistance and safety of lithium-ion batteries. Ceramic coated special diaphragm is especially suitable for power batteries.
Requirements for diaphragms for lithium-ion batteries:
The performance of the diaphragm determines the internal resistance and interface structure of the battery, and then determines the battery capacity, safety performance, charge and discharge density and cycle performance.
Therefore, the following characteristics need to be met:
Good chemical stability: resistance to organic solvents.
Good mechanical properties: high tensile strength and high puncture strength.
Good thermal stability: low thermal shrinkage and high film breaking temperature.
Electrolyte wettability: good compatibility with electrolyte and high liquid absorption rate.
As a kind of inorganic substance, aluminum oxide has high thermal stability and chemical inertia, so it is a good choice for battery diaphragm ceramic coating.
Performance requirements of ceramic diaphragm for alumina:
1. The particle size is uniform, which can be well glued to the diaphragm without blocking the diaphragm aperture.
2. Alumina has high purity and can not introduce impurities, which affects the internal environment of the battery.
3. The requirement of crystal structure of alumina ensures the compatibility and wettability of alumina to electrolyte.
Advantages of coating alumina diaphragm:
High temperature resistance:
Alumina coating has excellent high temperature resistance and can maintain the intact shape of the diaphragm above 180 degrees Celsius.
The alumina coating can neutralize the free HF in the electrolyte and improve the acid resistance and safety of the battery.
Nano-alumina can form solid solution in lithium battery, which can improve the magnification and cycle performance.
Nanometer alumina powder has good liquid absorption and liquid retention ability.
Unique self-turn-off characteristics:
The closed-cell characteristic of polyolefin diaphragm is maintained to avoid safety risks caused by thermal runaway.
Low self-discharge rate:
The alumina coating increases the curvature of micropores and the self-discharge is lower than that of the common diaphragm.
Long cycle life: reduce the mechanical micro-short circuit in the cycle process and effectively improve the cycle life.

The secretary of Ukraine's National Security and Defense Council said the US arms lease bill to Ukraine has not yet been implemented. This is still in the process and could start from July to September 2022, he said. The approval of this bill is a very positive decision for Ukraine. Aid to Ukraine through lend-lease will eventually come, the question is when.
In an effort to speed up the supply of weapons to Ukraine, President Joe Biden signed a defense lend-lease bill for Ukraine at the White House on May 9.
Nippon Steel, JFE Steel, and Kobe Steel will work together to develop a steel-making process that uses hydrogen to reduce carbon dioxide emissions without using blast furnaces. Small test furnaces will be built at Nippon Steel's Hwazaki Research and Development Center (Kamiki city, Ibaraki Prefecture) and JFE's East Japan Steel In Chiba (Chiba City). The two test furnaces, which will be operational by 2024-25, will confirm whether ore with high levels of impurities can also operate smoothly.
