Cylindrical Lithium

Innovating Safe and Stable Energy

Safely harness pure lithium energy with Panasonic Cylindrical Lithium. A lightweight, high-energy-density battery optimized for stable discharge in high-drain applications such as flash-enabled cameras, Cylindrical Lithium is perfect for continuous or intermittent use over long periods in various devices exposed to wide range of temperatures. This RoHs® and UL® certified battery series has earned a reputation for safety that’s proven by intensive lab tests, such as nail-puncture short-circuit tests, 13-kN crush tests, vibration tests, heat stress tests, and 10-year storage tests. It remains the world’s most trusted power source for specialized high-power applications in harsh environments.

High Energy Formula

High Energy Formula contributes to Cylindrical Lithium’s long-lasting endurance in mid- and high-drain applications, such as cameras, where the battery’s low internal resistance helps to reduce flash-recovery times for rapid burst shooting. High-purity MnO2 is filled at high density, extending life, while the corrosion-resistant stainless cathode core stabilizes discharge at high voltage. Lithium anode features a special aluminum additive that enhances high-power reactivity, while Anti-Leak Seal with durable gasket and use of gas-suppressing materials helps protect your devices from leakage even in tough operating environments.

Safety System Technology

Exclusive safety structure prevents short-circuits and leaks with fail-safe protections for over-current, over-voltage, and overheating, even if the battery is damaged. The system includes a thermosensitive PTC that detects temperature rises and increases resistance to prevent short-circuit; a built-in safety valve to relieve internal pressure; and durable gasket material that’s effective at preventing leaks. Panasonic Cylindrical Lithium is both UL® and RoHs® certified.

Reliable in a Wide Range of Temperatures

Various design aspects combine to preserve high capacity after long-term storage while enabling safe use in a wide -40 °C to +70 °C temperature range. Organic materials reduce the electrolyte solidification point to less than other battery types, optimizing storage and operation in low temperatures, while high-purity MnO2 has the optimal particle-size for high-rate discharge at low temperatures. Gas-suppressing materials, meanwhile, preserve capacity after long-term storage at high temperature. Anti-Leak Seal and short-circuit protections enhance durability.

Ultra-Low Self-Discharge

Research yields a more effective choice of electrolyte solvent, which forms a protective film over lithium to prevent ionization and self-discharge while in storage. In addition, calcination treatment conditions were set to prevent MnO2 from leaching into the electrolyte, slowing the rate of self-discharge. Cylindrical Lithium boasts a self-discharge rate of less than 5 % after 10 years*, so properly stored batteries are always ready when you need them.

* CR123, when stored at 20 °C, 100 Ω continuous discharge (discharge cutoff voltage: 2 V).

10-Year* Storage with Quality Assured

Proven battery design, refined materials, special electrolyte solvent, and precise calcination treatment result in a low self-discharge rate during storage. Panasonic Cylindrical Lithium can be safely stored without significant loss of capacity for periods up to 10 years* with improved resistance to heat and cold compared to other battery types.

* When in an unused condition and stored at room temperature.
