Do you know Batteries function best at room temperature? Do you know Batteries
function best at room temperature?Batteries function best at room temperature. Operating batteries at an elevated temperature dramatically shortens their life.
Although a lead acid battery may deliver the highest capacity at temperatures
above 30°C (86°F), prolonged use under such conditions decreases the life
of the battery. Similarly, a Li-ion performs better at high temperatures. Elevated
temperatures temporarily counteracts the battery's internal resistance, which is a result of aging.
The energy gain is short-lived because elevated temperature promotes aging by
further increasing the internal resistance. There is one exception to running a battery at high temperature — it is the lithium polymer
with dry solid polymer electrolyte, the true 'plastic href="http://www.good-battery.co.uk">battery'. While the commercial Li-
ion polymer uses some moist electrolyte to enhance conductivity, the dry
solid polymer version depends on heat to enable ion flow. This requires that
the battery core be kept at an operation temperature of 60°C to 100°C. The dry solid polymer battery has
found a niche market as backup power in warm climates. The battery is kept at
the operating temperature with built-in heating elements. During normal
operation, the core is kept warm with power derived from the utility grid.
Only on a power outage would the battery need to provide power to maintain
its own heat. To minimize heat loss, the battery is insulated. more info:www.good-battery.co.uk
