Since 2022, Russia-Ukraine geopolitical conflicts have intensified, and global energy prices have risen sharply, with international natural gas prices hitting historic highs. As the most important transitional energy source in the transition from fossil energy to non-fossil energy, the share of natural gas in primary energy has increased from 14.6% in 1965 to 24.7% in 2020.  The global gas price indices showed a unilateral downward trend from 2018, bottomed out in 2020, and remained low for a long time. However, since July 2020, the global gas prices have gradually fluctuated upward, and the impact of geopolitical events made the Dutch TTF gas price even hit record highs repeatedly.

An analyst of a securities company believes that the core catalyst of this round of global gas market lies in the lack of investment in upstream oil and gas resources caused by long-term low prices. Since 2020, although the epidemic has led to a decline in demand, the decline in supply has been faster, resulting in a large inventory consumption. In 2021, demand will recover faster than supply (the supply-side is less sensitive to prices, which will be reflected in investment).  

As the world's two largest gas lithium battery are also expected to change significantly.

Lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of lithium-ion batteries is fluid, so they are more unstable than lithium-polymer batteries, and they may explode if they are beaten by external forces or use substandard chargers. Many portable electronic products such as mobile phones and laptops use lithium batteries. In other words, many people have a "bomb" by their side. You must pay attention to the following points for safety reasons when purchasing.

1. Is there a clear indication of the capacity? Batteries that do not have a marked capacity (e.g. 1000mAh or 1000mAh) are likely to be of poor quality or recycled. Many cheap batteries on the market are made of recycled battery cores. Although the price is low, the lifespan is short, and the quality is unstable. Careless use may damage the phone.

2. There is no guaranteed standby time. Standby time refers to the continuous use time after the battery is installed in the mobile phone to the subsequent charging. Generally, the batteries sold on the market cannot guarantee the standby time for customers. This is because the quality of the batteries is unstable. Many cheap batteries use poor quality battery cores, so the standby time is short.

3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery is at risk of deformation, leakage and explosion. Under the vicious price-cutting competition, various companies seek lower-priced protection circuit boards or omit this device, making the market full of lithium batteries with a danger of explosion. Consumers cannot tell whether there is a protective circuit board from the appearance, so it is best to choose a reputable merchant to buy.

On January 19, 2022, The Ministry of Industry and Information Technology will guide relevant units to speed up the formulation of lithium battery coding standards.

Lithium primary battery

manganese dioxide

With metal lithium as the negative electrode and heat-treated manganese dioxide as the positive electrode, the separator is made of PP or PE film. The cylindrical battery is the same as the lithium ion battery separator. The electrolyte is an organic solution of lithium perchlorate, cylindrical or a button type. . The battery needs to be produced in a dry environment with a humidity of ≤1%.

Features: low self-discharge rate, annual self-discharge can be ≤ 1%, fully sealed (metal welding, laser seal) battery can meet ten years of life, the semi-sealed battery is generally five years, if the work control is not reasonable, it can not reach this life. Yiwei, which has done an excellent job developing cylindrical lithium-manganese batteries, has realized automatic production. The battery can be tested for short-circuit and over-discharge without explosion.

Generally, there is a button-type lithium battery on the motherboard of a desktop computer, which provides a weak current and can be used generally for about three years. Some hotels also use lithium-manganese dioxide batteries for access control cards, instruments, etc., which are used year by year decline.

Thionyl chloride

With metal lithium as the negative electrode, the positive electrode and the electrolyte are thionyl chloride (thionyl chloride), the cylindrical battery has electricity after assembly, and the voltage is 3.6V. quality) battery with the highest capacity. It is suitable for electronic instruments and equipment that cannot be maintained frequently and provides good current.

Other lithium batteries include lithium-ferrous sulfide batteries, lithium-sulfur oxide batteries, etc.

The COVID-19 pandemic has affected economies and chemical companies in many countries around the world. Measures such as extending holidays and resuming work were taken to control the development of the epidemic, and the normal operation of some chemical enterprises was also affected to some extent.
