Quickly emptying batteries are a disease of smart-phones and tablets. After all, it seems remedy on the way to be. Sony experimented with Sulphur Compound to increase the battery capacity by 40% for the same size as compared to lithium-ion polymer batteries.
The Japanese electronics group Sony plans to launch high performance rechargeable energy storage. We should increase term of energy-hungry smartphones, laptops and small electrical appliances by up to 40% no later than by 2020. Sony hopes to achieve a great leap in the performance data with a new generation of battery on the basis of a sulphur compound.
Lithium-ion batteries have reaching limits. Sulphur Compound does not and is storing high voltage directly from the grid.
Today plug into smartphones, tablets and laptops mostly lithium-ion batteries. They are considered the best available power memory, because they provide the best electrical performance with relatively low weight and volume. However, the growing power consumption of devices about due to larger screens, more powerful electronics and data-hungry apps push the batteries to their limits.
Lithium-ion batteries are based on the principle that electrons during the loading process is neutral stored at the cathode. When unloaded, the electrons wander back to the anode. Most batteries use positive electrodes of lithium cobalt oxide and other compounds. Sulfur compound allows high storage density
The new battery from Sony uses a sulphur compound as a material for the positive cathode, which allows a much higher storage density. A problem with lithium-sulphur batteries so far was that these compounds in use evaporate, causing a rapid battery discharge result.
Sony has found a solution to stabilize the battery due to changes of the electrolyte solution. The company is currently investigating the safety of the new product in order to create mass production.
Sulphur Compound Sony Battery Performance dATA
The lithium sulfur battery (Li-S) by Sony to can provide for 14 hours discharge. For example, iPhone 6 connected to the Internet with power stands for max. 8 hours (tested by cadincadout). The batteries should be compact 30% with the same performance. Another advantage is that sulphur is a material that is present and is really cheap worldly available.
Numerous new technologies at work
Lithium-sulfur batteries but are not the only new technology at the engineers worldwide are working. Currently, innovative processes for the production of special lithium batteries are explored, which uses a fixed, non-combustible electrolyte. Such so-called solid fabric lithium batteries are safe and durable and also have the potential to replace the current lithium-ion technology.
Another promising type of battery is the lithium-air battery, which boasts a very high energy density. This type of battery, the anode consists of metallic lithium and a cathode made of porous carbon. Atmospheric oxygen is the raw material. These “breathing” batteries have a big weight advantage over other types because they must carry any of the main components “air” not hard with himself.
High expectations for Li-S batteries
A particularly high potential is however awarded due to their high energy density and life lithium-sulphur batteries. Large electronics companies such as Hitachi, LG and Samsung SDI also working hard on the development of lithium-sulphur batteries.
A recent report by Techno-System although Sony in 1991 brought the first, simple lithium-ion battery on the market. Japanese company has only a market share in this area +- 8% research. Samsung SDI, LG Chem, and Panasonic have a share of 20% each.
