Sony is working hard to try to improve it’s batteries, and so it’s announced a new lithium-ion battery that should be more stable, as well as last much longer than typical batteries. This is thanks to olivine-type lithium iron phosphate for the cathode material, which helps boost the battery’s life to about four times that of conventional lithium ion batteries.

It will also have 80% capacity retention after 2,000 charge-discharge cycles. The biggest news is that it offers a promised 99% recharge in only 30 minutes.
