A company called SolidEnergy, a division of the Massachusetts Institute of Technology (MIT), has said that it has developed a new type of lithium-ion battery that can store two times as much energy per unit volume of current lithium batteries, and that it can still maintain high power after hundreds of charging cycles. Store online. Due to the popularity of mobile devices, the battery of the user's smart phone has become a big problem. In addition to mobile power, it seems that the industry has not made any breakthrough in this regard. But the technology of this company seems to bring us hope. It uses a principle that is not new: Lithium metal is used instead of the usual graphite electrode.
This technique is not used by the industry because such electrodes react with the electrolyte of the battery, causing electrode crystals to accumulate (dendrites) causing serious problems such as explosion.
However, the company has developed an ultra-thin lithium electrode and a solid and liquid electrolyte. Unlike conventional liquid electrolytes, it is not flammable and has additives added to prevent the electrode crystals from building up. The company said that battery prototypes using the new technology can store twice the current amount of electricity per unit volume. At the same time, 80% of the storage capacity is still reserved after 300 charges, which is very close to the performance of lithium-ion batteries used in current portable electronic products. The company also said that the technology can be easily integrated into existing battery manufacturing technologies.
SolidEnergy plans to launch the first portable electronic product using this battery technology in 2016 and plans to introduce the relevant models for electric vehicles. But it should be pointed out that there is usually a long way to go from amazing prototypes to batteries that can actually be produced.
That's really amazing if you don't know Axial fan
