can sony li-ion batteries recover market share? - lithium iron battery
Sony was once the leader of lithium. ion "Li-
Battery market.
In 1991, it was the first country in the world to commercialize them.
It focuses mainly on compact batteries for PCs and mobile phones.
According to Dr. Peter harops, chairman of lithium-IDTechEx
With strong demand for mobile phones, PCs and now electric vehicles, the market for ion batteries continues to expand.
For example, this battery is seen on more and more pure electric forklifts and ships, on most non-electric forklifts and ships
Road electric cars and almost all automatic underwater robots, unmanned aerial vehicles, electric aircraft and electric airships, not just in-
From buses to trucks, cars and some electric carsbikes.
Although Sony CEO Howard Stringer announced plans to enter the car battery business in 2009, Sony is clearly not involved in all of these car activities.
We can dig deeper now.
New computer analysis of 40,000 patents for advanced energy storage "advanced energy storage technology: patent trends and company positioning" reveals Sony's weak position in Li-related intellectual property rights
Ion in the automotive industry.
This shows that Sony is one of the largest patentees of lithium.
The general ion battery technology is second only to Panasonic, Samsung and LG Chem.
For example, it is applying for a patent to various cathode and anode chemicals at a stable speed
The main thing is to improve rather than a completely different option for the future, such as lithium sulfur or lithium air.
However, it does not add a patent for lithium
Unlike several other leaders, including Toyota, ion battery technology generally outpaced it, partly due to wider research.
More seriously, from the car's point of view, Sony is not even among the top 50 patentees of lithium.
Ion traction battery technology compared to lithium
Ion general, or related super capacitors, in-
The board charging system or battery management system is analyzed in the patent map of this new report.
On 2010, Sony announced it would spend $1.
5 billion build a mass production system for large capacity batteries.
If this is true, then it will invest at the leadership level in the traction battery field.
However, although it recently expressed interest in the battery business for fast charging systems, it has yet to announce mainstream traction batteries.
A special feature of the new Sony olive lithium iron phosphate OLFP battery is its long life, in addition, it also has excellent temperature stability and is not affected by the rising price of cobalt.
If it is fully charged and discharged once a day in an environment with a temperature of 23 °c, it can last for more than 10 years.
What contributed to this achievement was a significant improvement in the quality of the key raw materials used in the electrodes.
Electrode material is one of the most commonly used core materials of lithium
Ion batteries, so they wear faster than other battery materials and have a big difference in life.
Sony has studied a variety of materials that can increase the durability of electrode materials, and has proposed olive lithium iron phosphate, because its crystals are better combined than those made of nickel. -
A common electrode material-
Wear is slower even in the case of repeated charges, claiming 2000 cycles.
Battery modules using this technology are said to be able to 1.
8 KW/kg, four times the density of chemical energy before.
As hybrid cars become more like pure electric vehicles, they are closer to meeting the needs of consumers for longer periods of time.
Energy density is the most important thing.
