Battery developer StoreDot says it is working on a technology for “self-repairing” battery cells. The Israeli company, which specializes in extremely fast-charging cells, wants to improve the service life and performance of electric car batteries.
A new patented technology of the company identifies underperforming cells and temporarily disables them. The system, which includes a series of software algorithms with corresponding hardware, allows battery cells to regenerate during operation through a “seamless background repair mechanism”.
StoreDot’s newly developed system comprises “a series of software algorithms with corresponding hardware”.
The system is supposed to be able to temporarily deactivate individual cells or a cell string “in order to proactively recondition them back to 100% performance”. The driver should not notice anything, not even a loss of power.
StoreDot does not specify how exactly the repair or reconditioning is to take place. However, the company has recently been granted a patent for this called “Recovering defective branches and/or cells of battery packs by deep discharges”, which describes the methods.
StoreDot is known to be aiming to bring its XFC cell technology to market by 2024 – in cooperation with Chinese manufacturer Eve Energy, among others. The cells, which have a silicon-dominant anode, are said to reduce charging time by 50 per cent at the same cost. StoreDot is also working on solid-state cells (called XED by the company), which are to go into mass production by 2028.
