Is solidenergy's lithium metal battery true?

You can look at the relevant information first:

Lithium metal battery was developed by SolidEngergy Company of Massachusetts Institute of Technology. This technology can reduce the volume of lithium batteries by half, and it can be used in electric vehicles in the future. Although graphite has been proved to be the best and most reliable material used to make cathode so far, it contains a limited number of ions. Researchers have been hoping to replace graphite with lithium metal foil, which can contain more ions, but usually lithium metal foil will have an adverse reaction with electrolyte, leading to overheating or even combustion of electrolyte. Previously, A 123 Systems, another company from Massachusetts Institute of Technology, declared bankruptcy due to immature technology, which led investors to question battery technology. SolidEnergy took over the idle facilities of A 123, and then began to manufacture batteries independently in a commercially feasible way. SolidEngergy developed a lithium metal foil anode, which greatly reduced the size of the battery. However, this requires heating the battery to 80 degrees to work. To solve this problem, the team invented an electrolyte to wrap lithium metal foil.

SolidEnergy plans to launch its own UAV battery on 2011. SolidEnergy also plans to manufacture batteries for smart phones and other electronic devices in 20 17, while electric vehicle batteries will be launched in 20 18. Theoretically, if the battery volume remains unchanged and lithium metal batteries are used, the cruising range of electric vehicles will double. "Lithium metal battery" technology is an engineering breakthrough, which will greatly improve battery performance, enhance battery capacity and endurance, greatly improve the economic benefits of energy storage, and promote the upgrading and transformation of consumer electronic products, which is of great significance to human life.

It can be seen that solidenergy has made a lot of achievements in the research of lithium metal batteries, and it will take time to make the products practical, at least not mainstream at present.
