2.2 ‐‐ Performance at Other Environmental Conditions

When a Zinc Air battery is exposed to a non‐standard environment, a driving force for water transport in or out of the battery exists. Movement of water vapor into the battery can fill void space in the anode cavity under high humidity environments, and movement of water vapor out of the battery can dry out the electrolyte in low humidity environments. Either situation can decrease battery performance over time.

Understanding the environmental conditions that a battery might encounter is critical to estimating battery performance. A study was done at Energizer to determine realistic extreme conditions for battery testing, using climate data from 61 cities across the globe. These cities represent the major markets for both devices and batteries. Combinations of daily morning and afternoon temperature and humidity were compiled and analyzed to determine reasonable temperature and humidity extremes.

Hot and Humid Conditions:

Zinc Air Prismatic batteries can take on water when exposed to hot and humid conditions. This can limit battery performance by taking up void volume in the air electrode and anode compartment. At 35°C and 75% RH conditions, there is a driving force for water gain larger than 99% of conditions seen in combined indoor and outdoor data from the top 61 cities globally. Service tests with the PP355 under these conditions show very good service even at 1 hr per day intermittency.

Hot and Arid Conditions:

Zinc Air Prismatic batteries can lose water when exposed to hot and arid conditions which can limit battery performance by drying out the battery. Under 35°C and 25% RH conditions, there is a driving force for water loss larger than 99% of conditions seen in combined indoor and outdoor data from the top 61 cities globally. Service testing with the PP355 at these conditions shows very good service even at 1 hr per day intermittency.
