SroreDot Company, the developer of Extreme Fast Charging Battery, is going to open an R&D center in California. This major step is part of the company’s development efforts to create the next generation of its battery, which will be a Solid State one, with extreme energy-density (XED) and will allow for driving range greater in 50% than the current generation. At the same time, the company announced its negotiations with USA-based manufacturers to establish a local battery production line, in order to shorten supply chain for American customers. Currently, company’s batteries are manufactured in China by the local battery manufacturer EVE.
In Solid State battery, the electrolyte, through which ions pass in the loading-unloading process between the electrodes is made of solid material. In the existing Lithium-Ion batteries, the electrolyte is usually made of liquid or polymer-gel. Solid State batteries are considered safer, since they don’t suffer from current batteries’ dangers such as high temperatures flammable or explosion, liquid leakage etc. in addition, the Solid State battery’s capacity should be larger, allowing for higher driving range. The main challenge is to develop a solid material that will be solid at the one hand, and high conductivity at the other hand. Also, the developers have to cope with solid electrolyte’s tendency to crack and be broken.
The Solid State battery is considered to be the Holy Grail of the EV industry, the one that will make electric vehicles cheaper, safer and with higher driving range, soothing range anxiety. Many players at the vehicle industry put a lot of efforts in developing Solid State batteries. One of the leaders in these development efforts is Toyota, lately announced an $13.5 billion investment plan for developing new batteries technologies and production capabilities, to include a Solid State battery. The Japanese manufacturer is expecting to complete the development of the battery in the middle of current decade, although lately admitted that it struggles with some technical difficulties. Among other manufacturers, Ford, BMW, and Volkswagen are all in the race for developing Solid State battery. The American EV manufacturer of Fisker, which has much more limited resources being a start-up company, announced six months ago that it completely cancels its program to develop such battery.
Ultra-fast charging of EV’s batteries
StoreDot has developed the FlashBattery technology, allowing Li-ion batteries to be charged in only several minutes. This technology is based on NanoDots particles, each at the size of 2 nanometers, characterized by high capacity and integrated in the electrolytic liquid within the battery.
In early 2021, StoreDot has produced the pilot production batch of EV batteries in a plant of the Chinese battery manufacturer Eve Energy. These batteries were used to demonstrate full charge of a two-wheeled EV in just five minutes. At May 2021 StoreDot signed an agreement with Eve Energy, under which it will produce early samples for clients by the year end, and starting at 2024 it will mass-produce the batteries for integrating in various EVs.
