What are the main materials of lithium batteries?
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 batteries are also expected to change significantly.
Carbon anode material
The actual negative electrode materials used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.
Tin-based anode material
Tin-based anode materials can be divided into tin oxides and tin-based composite oxides. Oxides refer to oxides of metal tin in various valence states. There are no commercial products.
There are no commercial products.
Including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, there are also no commercial products.
Carbon nanotubes, nano-alloy materials.
According to the latest market development trend of lithium battery new energy industry in 2009, many companies have begun to use nano-titanium oxide and nano-silicon oxide to add to the previous traditional graphite, tin oxide, and carbon nanotubes, which greatly improves the charging and discharging of lithium batteries. volume and charge and discharge times.
What are the causes of battery explosions?
1. The internal polarization is large;
2. The pole piece absorbs water and reacts with the electrolyte;
3. The quality and performance of the electrolyte itself;
4. When injecting liquid, the amount of liquid injection cannot meet the process requirements;
5. The laser welding sealing performance is poor in the assembly process, and the air leaks when the air leakage is detected;
6. Dust and pole piece dust are easy to cause micro-short circuit first;
7. The positive and negative plates are thicker than the process range, and it is difficult to enter the shell;
8. The problem of liquid injection and sealing, the poor sealing performance of steel balls leads to air bulging;
9. The incoming shell material has a thick shell wall, and the shell deformation affects the thickness;
10. The high ambient temperature outside is also the main reason for the explosion.

Researchers at the University of Warwick in the UK have developed a lithium battery technology innovation. Adding graphene beams doubles battery life. By strengthening the structure of the anode with graphene beams, they have found an effective way to replace the graphite in the anode with silicon. Thereby increasing the capacity of the lithium-ion battery and more than doubling the lifespan.
