Key Engineering Advantages
1. Form-Factor Optimization (Only 10.2mm Thick)
By swapping out rigid metal canisters for a vacuum-sealed aluminum-laminate pouch, the CP1004040 eliminates dead space. It easily integrates flat against PCBs, slides into low-profile handheld enclosures, or fits within flush-mounted wall sensors where standard cylindrical or coin-cell batteries are simply too thick or heavy.
2. Exceptional Temperature Survivability ( -40℃~60℃)
From cold-chain cargo tracking on high-altitude flights to remote oil field telemetry in the desert heat, this pouch cell is chemically formulated to stay stable. Its specialized organic electrolyte remains fluid and highly conductive at -40℃ and resists chemical breakdown and gas generation up to +60℃.
3. 10-Year Standby Life (≤ 2% Annual Self-Discharge)
With a self-discharge rate of less than 2% per year, this battery is optimized for emergency standby systems, low-frequency remote sensors, and infrastructure equipment that must remain reliable for years without human intervention.
4. Safety-First Pouch Architecture
Traditional steel-can batteries present a risk of high-pressure explosion under severe electrical or physical abuse. Under extreme stress, the flexible laminate packaging of the CP1004040 safely expands to release minor pressure, ensuring your expensive electronic housing remains intact and safe from high-velocity shrapnel.
Targeted Industrial Applications
The CP1004040 is the preferred primary power choice for flat-panel, high-drain, and long-standby electronic configurations:

Frequently Asked Questions
Q1: Can the CP1004040 primary soft pack battery be recharged?
A: No. The CP1004040 is a primary (non-rechargeable) Lithium Manganese Dioxide chemistry. Attempting to charge this cell can cause internal shorts, leaking, or permanent battery failure. If you require rechargeable options, reach out to our engineering team for specialized Li-polymer solutions.
Q2: Does the soft-pack battery experience performance drops during RF pulse transmissions?
A: Our proprietary LiMnO2 formulation is specifically designed to keep passive internal resistance low. This maintains a highly stable operating voltage plateau, preventing the severe voltage drops often seen in standard lithium batteries during heavy RF signal transmissions (like NB-IoT or LoRa).
Q3: What makes this soft pack safer than traditional cylindrical primary batteries?
A: Cylindrical batteries hold internal gas pressure within a rigid steel casing, which can turn into a physical safety risk during thermal runaway. Pouch cells, such as the CP1004040, vent built-up gas slowly and non-explosively via their flexible foil seams under abusive conditions.
