Officials stated that lithium batteries permanently lose some active lithium ions during the manufacturing process. Researchers pre-treat the lithium battery anode to allow it to hold more lithium ions, thus increasing battery capacity.
IT Home has learned that this South Korean research institute uses a solution containing lithium ions to prevent lithium from being consumed in silicon electrodes. Furthermore, by adjusting the interaction of molecules in the solution, they have developed a new solution that does not damage the graphite.
The lithium-ion battery manufactured using this technology has 260% of the capacity of current graphite anode lithium-ion batteries, and retains 87.3% of its capacity after 250 charge-discharge cycles. Researchers say this technology could help improve the driving range of electric vehicles.
