Sony Launches High-power Long-life Lithium Ion Secondary Battery

Sony has launched a new type of lithium ion secondary battery that combines high-power and long-life performance, using olivine-type lithium iron phosphate as the cathode material. The Olivine-type lithium iron phosphate used in this new battery is extremely suited for use as a cathode material due to its robust crystal structure and stable performance, even at high temperatures. This new battery can be charged to 99% of its full capacity in 30 minutes, which represents approximately half the charge time of Sony’s current lithium ion battery line-up (G-series, A-series), which mainly use cobalt oxide based cathodes.

This new battery delivers an extended life-span of over four-times existing secondary lithium ion batteries used in conventional electronic devices (G-series, A-series) due to the olivine-type lithium iron phosphate’s robust crystal structure, and Sony’s proprietary particle design technology. Its enhanced durability makes this new battery ideal for use in a wide range of mobile electronic devices. The new Sony battery measures 18mm x 65mm and weigh 40g.
