Lithium-ion batteries are a common type of rechargeable batteries that are widely used in electronic devices, electric vehicles and energy storage systems due to their high energy density and long cycle life. However, Li-ion batteries are subject to aging over time, leading to their performance degradation or even failure. In this article, we will discuss in detail the types of causes of lithium-ion battery aging and how to determine the degree of battery aging and whether it needs to be replaced.
Battery aging refers to the battery after a period of use or storage, its performance gradually decline in the process. This decline in performance is manifested in the reduction of battery capacity, increased the lithium ion battery internal resistance and charging and discharging efficiency. Battery aging is an inevitable phenomenon that affects all types of batteries, including lithium batteries used in electric motorcycles and other electric vehicles.
The aging of lithium-ion batteries is mainly divided into performance aging, safety aging and cyclic aging cyclic aging.
This refers to a significant decline in capacity during normal use, cycle life decay, increased internal resistance, self-discharge, poor consistency and high and low temperature aging.
Safety aging mainly due to inappropriate use of the environment, the use of the way caused by the internal short circuit, liquid leakage, inflation and precipitation of lithium and so on.
It refers to the phenomenon that the performance of the battery gradually decreases after many charging and discharging cycles. Each charge and discharge will cause a certain amount of loss, which cumulatively will lead to a decline in the overall performance of the battery. Especially when the battery works under high current or high temperature conditions, this loss will be more obvious.
The battery electrolyte in lithium batteries is a conductive medium, which volatilizes and decomposes during the charging and discharging process, resulting in the loss of battery capacity. The rate of this decomposition and volatilization increases with the number of battery cycles.
During the charging and discharging process of the battery, the positive and negative electrode materials undergo a chemical reaction to form the embedding and de-embedding of lithium ions. This chemical reaction leads to depletion of the electrode material, which reduces the capacity and performance of the battery.
During the charging and discharging process, physical and chemical changes occur within the battery, such as particle aggregation of the cathode material, dissolution of the electrolyte, and interfacial reactions between the electrode and the electrolyte. These changes can lead to an increase in the resistance inside the battery, thus reducing the performance of the battery.
High temperature is an important factor in the aging of lithium batteries, which accelerates the rate of reaction within the battery, leading to a reduction in battery capacity and safety. In addition, humidity, oxygen and other environmental conditions can also negatively affect battery life.
Battery capacity is the ability of a battery to store and release energy. As the battery ages, the electrode material depletes and the electrolyte solution evaporates, the usable capacity of the battery gradually decreases. This means that the amount of power a battery can supply after a single charge decreases, and the usage time is shortened accordingly.
Aging of lithium batteries also leads to a decrease in charging efficiency. The loss of electrode materials and the decomposition of electrolyte solution will increase the internal resistance of the battery and reduce the efficiency of energy transfer. As a result, the time required to charge the battery will become longer and the charging efficiency will be reduced.
The cycle life of lithium batteries, i.e. the upper limit of the number of charge/discharge cycles, will decrease with battery aging. Battery aging will lead to the depletion of electrode materials and decomposition of electrolyte solution, which will gradually reduce the capacity of the battery during the cycle process, and eventually reach the level that it cannot work normally.
Aging of lithium battery also reduces lithium battery safety. The acceleration of the internal reaction of the battery and the loss of electrode materials will generate more heat, increasing the risk of overheating, short circuit and explosion.
Avoid fully discharging the battery before recharging, and try to keep the battery in the 20%-80% charge range.
Avoid high temperature environments when using the battery and do not expose the battery to cold environments.
Use the original charger for charging and follow the manufacturer’s recommended charging method, avoid using rapid charging unless necessary.
Regularly check the working condition of the battery to ensure that it has good contact and no corrosion or other problems.
If the battery is not used for a long time, store it in a proper environment and perform regular charging and discharging operations to keep the battery active.
From the battery itself, you can go to a specialized repair store to check it. If the battery is already deformed or bulging, it is recommended not to use this battery, and should choose to replace it with a new one.
From the vehicle range point of view, if an electric car new battery range can reach 60 kilometers, then when the battery is used for many years, if the range is less than 12 kilometers, then the vehicle battery has been seriously aging, this time is generally not recommended to continue to use, but should be replaced with a new battery, because the durability is too poor, not durable.
From the electric car charging point of view, if an electric car charger is not faulty, but the motorcycle battery not charging or full charge, and once used there’s no power. this indicates that the battery failure may have been seriously aging. It is recommended to replace the battery with a new one.
From the electric car battery life, if a new set of batteries have been used for many years, and battery performance with the growth of the use of years can clearly feel the decline, then this time basically indicates that the battery has been aging, need to directly change motorcycle battery.
From the electric car charging frequency changes, travel distance remains unchanged, if an electric car originally 4 to 5 days for a charge, and as time goes by, the need for a day a charge or a day two charging, then the probability is also battery aging, this time is generally also the need for a new one.
In short, battery aging is a complex natural process, but through reasonable use and maintenance, can significantly slow down the rate of battery aging, thus extending the service life of the battery. For electric motorcycles and other electric vehicles, good battery management is not only the key to ensure the normal operation of the vehicle, but also an important measure to reduce operating costs.
