PANASONIC LÍTIUM GOMBELEM
POWERING SMART SOCIETY
All around you, Panasonic Coin Lithium batteries are providing safe power in devices we all depend on for life. High energy density and high 3 V output voltage support the trend towards device miniaturization. In fact, a single Coin Lithium can sometimes replace two or three conventional coin batteries. Use of organic electrolytes with a solidifying point lower than other battery types makes Coin Lithium ideal for use in wide range of temperatures. Backed by 90 years’ leading technical expertise, Panasonic Coin Lithium has evolved to become the world’s trusted micro-battery for safe, long-lasting power in diverse applications, from household electronics to the IoT devices that energize smart society.

LONG LASTING TECHNOLOGY
SAFETY TECHNOLOGY
OPTIMIZED MATERIAL FORMULATION
Perfected over years of research, High Power Energy Core features an optimized material formulation that increases energy density, output voltage, storage life, and discharge capacity for overwhelmingly long-lasting performance in high-drain applications as well as in low-drain pulse-discharge applications, such as keyless entry devices.
The formula includes a graphite additive to improve manganese dioxide utilization, and a heat-resistant binder for stability in hot conditions.
Coin Lithium Materials
MnO2: Manganese dioxide determines battery capacity
Carbon (graphite): Auxiliary material improves utilization rate of MnO2
Binder: Heat-resistant substance binds MnO2 and graphite
THE SECRET BEHIND THE STRUCTURE
Coin Lithium has a unique case design that contributes to its amazing endurance. Concave cathode case and dimpled anode surface increase material adhesion, limit a rise in internal resistance, and support stable voltage and efficient discharge for lasting power.
Cathode (+) Concave Case Design
Improves adhesion, limits a rise in internal resistance, stabilizes discharge, and extends life
Anode (-) Dimpled Surface Design
Increases adhesion to lithium and anode material, stabilizing discharge and extending life
TECHNICAL INGENUITY CREATES THE ULTIMATE ANTI-LEAK STRUCTURE

Anti-Leak Seal Technology
Combines a locked seal structure, tough gasket, robust anode cap, impact-resistant case, and quality materials that resist deterioration over time.
RIGOROUSLY TESTED FOR YOUR PEACE OF MIND
Panasonic prides itself on the scale of its testing program, which not only exceeds our competitors’ commitment, but also the industry’s toughest quality and safety benchmarks. Dedicated facilities simulate operation in heat, cold, and humidity, with batteries also tested for resistance against long periods in storage, impact, pressure, and vibration. Results are used to continually improve battery design.
CRUSH TEST
1,300 kg pressure-test evaluates burst resistance
LONG-TERM TEST
checks capacity after 5 years in storage
HEAT STRESS TEST
confirms leak resistance in a -10–60 °C temperature range
VIBRATION TEST
proves stability in the harshest applications
CHILD RESISTANCE PACKAGING
Warning labels displayed on the package (and stamped on the battery itself) remind you to keep unused batteries secure.
Our tamperproof package is recognized by IEC as the world standard benchmark for child-resistant packaging.
These initiatives limit chance of accidental ingestion and are a key part of Panasonic’s comprehensive safety system.
