Japanese research and development firm Eamex has discovered a new way to increase the typical lifespan of a lithium-ion battery.

Eamex’s new battery technology will allow the batteries to sustain over 10,000 recharges over the course of 20 years, compared to the conventional 1,000 charge cycles.

The secret to the long-lasting lithium-ion?

Currently, the tin in the battery’s negative electrode weakens through continual recharging. The new design, however, calls for tin-coated resin that stabilizes the electrode and prevents deterioration.

Lithium-ion batteries are very popular within various consumer electronics because they tend to hold their charge when not in use, and have a high energy-to-weight ratio.

We can also put off buying new gadgets (like mobile phones) which usually have batteries lasting 2 years or less, after which the phone performance time dipped even with full recharge.
