Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.
Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the lithium battery market.
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
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.
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.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the lithium battery is erratic and thus its prices are expected to go higher in the future.
