LIFE & SOCIETY

Trusted Power for Specialized Devices

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.

Look Inside

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.

Coin Lithium Structure
 

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

Panasonic innovated Anti-Leak Seal and lab-tested exhaustively in real-world appliances. The tough gasket’s rim is embedded in the case and is sandwiched tightly shut with a custom anode cap and strong adhesive. Enhanced by low-degradation ingredients, Anti-Leak Seal keeps you and your devices safe.

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-Resistant 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.
