This is where Mya Le Thai’s magic gel comes in. Typically, a Lithium Ion battery can go through between 5000 and 7000 recharge cycles before it dies and will also gradually lose its energy storage capacity over time. When researchers applied Thai’s plexiglass-like gel to gold nanowires in a manganese dioxiode shell, it increased that number to over 200,000 and the battery didn’t lose any of its power or storage capacity over a period of three months.
