What is a lithium-ion battery and how does it work?
A lithium-ion battery is a type of rechargeable battery that powers many portable electronic devices, electric vehicles, and renewable energy systems. It works by moving lithium ions between the positive and negative electrodes during charging and discharging cycles. When the battery is charged, lithium ions flow from the positive electrode (cathode) to the negative electrode (anode), storing energy. During discharge, the flow reverses, providing electrical energy to power devices.
These batteries are popular due to their high energy density, lightweight design, and ability to maintain a charge for long periods. They are also known for having a relatively low self-discharge rate, allowing them to retain a charge longer than some other battery types. However, they can lose capacity over time due to factors like age, usage patterns, and environmental conditions.
What are some common causes of lithium-ion battery degradation?
Lithium-ion batteries can degrade due to several factors, including temperature extremes, overcharging, and deep discharging. High temperatures can accelerate the aging process, leading to a decrease in capacity and overall performance.
