The change in temperature on the lithium battery charge and discharge performance what effect?

Source: 2020 - 04 - 02 'hits: lithium battery manufacturer in detail what is the effect of temperature change on the lithium battery charge and discharge function? The influence of temperature on the battery discharge function directly reflected in the discharge capacity and discharge voltage. Temperature drop, battery internal resistance increases, electrochemical reaction speed slow, polarization resistance increases, the battery discharge capacity and discharge path is reduced, affect the battery power and energy output. The temperature change of the second detailed by lithium battery manufacturer of lithium battery charge and discharge function is what effect? Lithium battery manufacturer in detail what is the effect of temperature change on the lithium battery charge and discharge function? Charging power charge ratio and the influence of ambient temperature. Charging current when charging must be within a certain range, too small or too large, electricity charge rate will be lower. Discharge power refers to the certain discharge conditions, released at the end of the discharge voltage from discharge to actually get the ratio of power and the rated capacity. It is mainly by the discharge rate, the influence of environmental factors such as temperature, internal resistance. In general, the higher the discharge rate, the lower the discharge power. The lower the temperature, the lower the discharge power. Professionals know general battery, lithium battery charge and discharge situation is stable, the change of temperature has great influence on the components, lithium battery charge and discharge in high temperature environment, lithium battery capacity rate declined. 1. If the temperature drops, the lithium battery inside the reaction rate will decline, the output of the battery power will decline; Assume that the temperature rising in the opposite direction, namely the lithium battery power output will rise. 2. However, if the temperature is too high more than 60 ℃, in the chemical balance of the battery will be destroyed, cause side effects; Under high temperature, the rechargeable battery material performance will deteriorate, will greatly shorten the life of the battery. 3. Under various environmental factors, the environment temperature has a great influence to the battery charge and discharge function, because of the electrode/electrolyte interface electrochemical reactions related to the environmental temperature. The heart of the electrode/electrolyte can be called the cell; With the loss of the temperature, the electrode reaction rate also decreases. The change in temperature directly affects the discharge function and discharge capacity of lithium-ion batteries. Temperature drop, battery internal resistance increases, electrochemical reaction speed slow, polarization resistance increases, the battery discharge capacity and discharge path is reduced, affect the battery power and energy output. Users do not know many battery, consumption lithium battery can't charge less than 0. While charging battery seems normal, but in the process of low-temperature charging, lithium anode may appear metal plating, it is permanent, not going to disappear as the charging cycle. Assumes that the lithium battery exposed under the condition of oscillation or other pressures, lithium batteries more brief flawed, and advanced charger can prevent the lithium battery charging in subfreezing temperatures. About lithium battery, under the condition of low temperature to devolve power has fallen sharply, but under the condition of high temperature to devolve power is not lower than the normal temperature, sometimes slightly higher than the normal temperature capacity, first is the high temperature circumstances lithium ion movement speed is accelerated, lithium electrode is not like a nickel electrode and hydrogen storage electrode in the case of high temperature decomposition or form hydrogen capacity declined. When the battery module in low temperature to devolve electricity, it will follow the discharge. Due to reasons such as resistance, heat will raise the temperature of the battery, show the voltage rise phenomenon. Lithium battery the best working temperature of 0 ~ 35 ℃, low temperature environment can reduce the activity of lithium ion, discharge capacity of a battery, use a shorter time; Assume that lithium battery short time exposed to low temperatures, the damage is only temporary, will not cause damage to battery capacity. When the temperature rises, the function will return.
