LITHIUM COIN BATTERY
General Information on Lithium Coin Cell Batteries
Lithium is among one of the lightest alkali metal elements and its standard potential and electrochemical equivalence are top of its class at approximately 3V.
The lithium in coin batteries like the CR2032 refers only to the anode material (i.e. negative pole). The cathode and electrolyte can consist of a variety of materials to provide different power cell characteristics.
The Lithium Manganese Dioxide chemistry in REVPOWER Lithium Coin Batteries is one of the most reliable and safeest lithium coin battery systems.
Unlike other battery chemistry’s, our battery construction produces power cells that are:
- short circuit proof
- user-replaceable as per Underwriter Laboratories (3V)
There are also other advantages:
- Approximately double the voltage level of typical alkaline button cells
- Wide operating temperature range from -30°C to +70°C
- Low self-discharge of about <1% to 1.5% per year at normal room temperature
- Efficient and practical volume to power capacity ratio
- Excellent leakage resistance
- Top of class storage shelf-life, from 5 years and up to 10 years storage depending on storage conditions
- UL-recognized products
- Does not contain toxic substances like mercury, making for a safe product
REVPOWER lithium batteries offer excellent storage shelf-life. The loss of capacity from self-discharge is from <1% to 1.5% per year at normal room temperature. The stability of the MnO2/Li chemistry in our lithium coin batteries enables a shelf life of up to 10 years, at room temperature.
The loss of capacity while the battery is in storage largely depends on storage temperature. The higher the temperatures the higher the self-discharge rates, while lower temperatures reduce self-discharge (as shown by graphs below). This is because higher temperatures accelerate the battery’s internal chemical reactions. Storage at low temperatures, however, puts the batteries at risk of being short-circuited by moisture from condensation.
Our lithium coin batteries are not rechargeable (do not attempt to recharge unless the coin batteries are expressly labeled as rechargeable).
The battery seal and the use of organic electrolytes offer superior leakage resistance. Each production lot is subjected to a quality assurance program under varying environmental conditions. REVPOWER batteries can be operated in any physical position.
