Higher charging temperatures negatively affect battery life in several ways, including degradation of chemical components, safety risks, and long-term performance.
-
Accelerated Degradation: Higher charging temperatures accelerate degradation. This process occurs when elevated temperatures cause breakdowns in the chemical structure of the battery materials. For instance, lithium-ion batteries experience quicker loss of active materials, which leads to shorter lifespan. A study by N. Pop et al. (2016) highlighted that temperatures exceeding 30°C can lead to a 20% reduction in battery capacity over time.
-
Thermal Runaway: Thermal runaway refers to a situation where an increase in temperature causes further temperature increases in a battery. This can result in fires or explosions. The Battery Safety Monitoring Consortium states that elevated temperatures can exacerbate this risk significantly. When cells heat up, reactions inside the battery become uncontrollable, thus creating a safety hazard.
-
Reduced Overall Capacity: Higher charging temperatures can lead to a permanent loss of capacity. This capacity reduction means that batteries cannot hold as much energy as they initially could. Research conducted by the University of Texas indicates that for every 10°C increase in temperature, capacity loss can accelerate by as much as 10% over a battery’s lifespan.
-
Impact on Cycle Life: Cycle life refers to how many charge and discharge cycles a battery can endure before its capacity wanes significantly. Elevated temperatures reduce cycle life because they stress battery components. According to a report by the National Renewable Energy Laboratory, high charging temperatures shorten the cycle life of a lithium-ion battery by nearly 25%.
-
Altered Internal Resistance: Higher temperatures can change a battery’s internal resistance. Increased internal resistance leads to reduced efficiency during discharge. This can cause more heat generation during use, further escalating thermal issues. According to work by M. N. K. Alavi et al.
