Lithium Polymer Battery
Presently, demand is rising rapidly for lightweight and thin portable information
& communication devices such as portable phones, portable audio systems and
PDA (personal digital assistants). Similarly, there is demand for thin and
lightweight batteries for use in these devices. SANYO's lithium polymer battery
can be utilized in a wide variety of market products.
SANYO has developed, and introduces a lithium polymer battery that achieves
an ultra-thin under 4mm with high performance through its own original
technology and high reliability employing a complete gel-type electrolyte.
Lithium polymer battery is new generation rechargeable battery to meet the
demands of evolution to various, thinner and lighter battery.

Main Features
●High Performance and High
Reliability with Newly Developed
Complete Gel Type Electrolyte
The newly developed polymer electrolyte
obtains superb long life reliability, featuring
more than 500 recharging cycles while also
achieving high performance (gravimetric
energy density of 166Wh/kg & volumetric
energy density of 348Wh/l).
●Excellent Discharge
Characteristics that Allow for
Discharge at 20°C
Typical points of weakness for lithium polymer
batteries were its load and temperature
characteristics. This newly developed polymer
electrolyte possesses high ion conductivity
even at low temperatures, thus making
possible discharges at 20°C.
●● Cross section
●Achieves an Ultra-Thin Type
Thickness of Under 4mm
It was possible to achieve both an ultra-thin
type thickness of under 4mm and obtain high
leakage-resistance even when utilizing thin
and light aluminum laminated film as the
exterior packaging material because the
electrolyte is completely gel-type.
