As soon as a battery is manufactured, it immediately begins to lose its charge—it discharges its energy. Discharge occurs at variable rates based on chemistry, brand, storage environment, temperature. Self-discharge denotes the rate at which the battery self-depletes in idle storage. All batteries self-discharge over time even when idle.

6 FAQs about [Battery in long-term discharge]
Why do batteries deteriorate at higher depths of discharge?
They found that the primary reason for the accelerated capacity degradation of batteries at larger depths of discharge is the LLI. Additionally, increasing the depth of discharge leads to a rapid increase in the internal resistance of the batteries.
Why are batteries not fully discharged after charging?
In practical applications, batteries are often not fully discharged after charging, allowing them to undergo charge and discharge cycles within a certain depth of discharge (DOD). A lower DOD means that the battery operates at a higher voltage.
How does battery aging affect charging and discharging rates?
The aging of batteries is significantly influenced by the charging and discharging rates. During the charging and discharging process, heat in the battery originates from Joule heat, chemical reactions, and phase transitions.
Why do lithium ion batteries lose active material?
Additionally, in the charge and discharge cycle of the battery, the anode material undergoes volume changes due to the intercalation and de-intercalation of lithium ions. This expansion and contraction can lead to fatigue, cracking, and even detachment of the anode material, resulting in a loss of active material [16, 27, 31].
Why do lithium ion batteries go bad?
Over time and exposure to environmental conditions, the performance of lithium-ion batteries diminishes, resulting in reduced electrical energy storage capacity and power output, ultimately culminating in the end of battery life [3, 4].
What happens if you charge a lithium ion battery at low temperatures?
Charging at low temperatures can lead to slowed diffusion of lithium in both the SEI and graphite, resulting in the anode of lithium-ion batteries developing an overpotential that exceeds the Li/Li + redox couple.
