20 Years and 10,000 Charges? New Lithium Ion Battery Touts Big Numbers

The numbers say it all- The Japan-based company Eamex is claiming to have developed a lithium ion battery that could very well be a new standard for automobile batteries of any kind. The initial reports on them, coming from Eamex, is that they can be charged and discharged over 10,000 times, while lasting up to 20 years overall. Impressive.

The method behind the madness? Apparently Eamex has come upon a new way to manufacture their lithium ion batteries that allows them to significantly increase the lifespan of the high-capacity li-ions.

The main idea is to stabilize the electrodes and prevent the deterioration of tin, making the batteries withstand repeated charges. The batteries have a negative electrode that incorporates a tin-coated resin and accumulates lithium ions coming from the positive electrode. The positive electrode is made of silicon and tin and swells while generating the ions.

As a result, the repeated charging and discharging causes the binding between particles in the tin to weaken, but Eamex’s technology helps to effectively maintain the bonding among those particles. -Eamex-

As with most industry announcements, taking these numbers with a grain of salt is usually recommended. Still, If Eamex produces a battery with anything resembling those types of spec’s, it would likely be classified as ‘industry-leading’.

Eamex says they have plans to push out a lithium ion battery within the year, possibly used to charge electric scooters with. Prius anyone?
