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 graphite still face uncertainty.
Lithium-ion battery refers to a secondary battery system in which two different lithium intercalation compounds that can reversibly intercalate and deintercalation lithium ions are used as the battery's positive electrode and negative electrode, respectively. During charging, lithium ions are deintercalated from the positive electrode through the electrolyte and separator and embedded in the negative electrode; on the contrary, lithium ions are deintercalated from the negative electrode through discharge of the electrolyte the separator and embedded in the positive electrode. The negative electrode of the lithium-ion battery is made of harmful electrode active material, binder, and additives mixed to make a paste glue, which is evenly spread on both sides of the copper foil, dried, and rolled.
Advantages of graphite as anode material
Graphite is an allotrope of carbon, and the two are closely related. Graphite is the most stable form of carbon. (Diamond is a metastable allotrope of carbon. Although its hardness is much higher than graphite, it is the hardest substance in nature, but its stability is lower than that of graphite.)
The word "graphite" comes from the Greek word "graphein," which is resistant to high temperature and corrosion, has good electrical conductivity, thermal conductivity, and stable chemical properties, and is lighter than aluminum. In addition to being used as anode material for lithium-ion batteries, high-quality graphite can also be used in different fields such as fuel cells, solar cells, semiconductors, light-emitting diodes, and nuclear reactors.
In general, graphite has the advantages of high electronic conductivity, the small volume change of layered structure before and after lithium intercalation, high lithium intercalation capacity, and low lithium intercalation potential, and has become the mainstream commercial lithium-ion battery negative electrode material.
How to get graphite?
There are two ways to obtain graphite: one is natural ore, and the other is the synthesis of coal tar. The graphite materials used in lithium-ion batteries are generally prepared by blending 55% synthetic graphite and 45% low-purity natural graphite.
Manufacturers once favored synthetic graphite because the uniformity and purity of synthetic graphite were better than natural graphite. Now it is not the same. The application of modern chemical purification methods makes it possible to obtain 99.9% pure natural graphite after heat treatment. In contrast, synthetic graphite is 99% pure, making the former more popular.
Compared with synthetic graphite, purified natural flake graphite has higher crystallinity and exhibits better electrical and thermal conductivity. In addition, natural graphite is expected to reduce the production cost of lithium-ion batteries while achieving equal or better battery performance.

Cancer cells can "stretch out a big hand" and take away the mitochondria of immune cells. The Harvard Medical School research team cultured mouse and human breast cancer cells and immune cells, such as killer T cells, and used field emission scanning electron microscopy (FESEM) to observe the relationship between cancer cells and immune cells. interactive. Interestingly, they found that cancer cells stick out long nanotubes, typically within 100-1000 nanometers in diameter, each of which connects to multiple immune cells along the way. The researchers used the drug L-778123, which inhibits the formation of nanotubes, for treatment. The higher the concentration of L-778123, the better the treatment effect.
