How to choose lithium battery?

Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the lithium battery still face uncertainty.

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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022. 

If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.

Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.

Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the lithium battery will develop in the future is still uncertain.
