The difference between the lithium ion battery and nickel metal hydride battery charging method

Source: 2020 - 04 - 4 children of hits: the difference between the first lithium ion batteries and nickel-metal hydride batteries 1. High power density, the volume of nickel metal hydride batteries are close to nickel metal hydride battery and lithium ion battery, embodies the features of nimh batteries. Considering the power density difference, namely under the same volume can store energy, lithium ion batteries is 3 times of nimh batteries. 2. Self-discharge rate: usually refers to the battery self-discharge in the condition of strong have no choice, will lose its power. Nickel metal hydride battery and lithium ion battery self-discharge is not very big, but nimh battery self-discharge rate exist for a long time, the battery is too large to allow this period of choice to reduce self-discharge, the service life of an early end. So in more than a decade ago, low self-discharge nickel metal hydride battery is nickel metal hydride batteries promotion activities, and lithium ion battery self-discharge rate can be ignored, it is lead to different chemical properties of the pure natural raw materials. 3. No memory effect, nickel metal hydride battery memory effect obviously. Memory method is the first impression on the brain, nickel metal hydride batteries are the same, not fully charged battery or the battery cannot be satisfied, in a long period of time will make the battery only remember incomplete, not satisfied, the performance of the application's storage capacity attenuation. Lithium ion battery without this feature. So, every once in a while, nickel metal hydride batteries is complete once the depth of the battery charging, to clear lettering method of memory, this is similar to brainwashing. Lithium ion battery can charge anytime and anywhere, make lithium-ion batteries' happy battery, we are also happy. 4. High charging work platform. A lithium ion battery voltage is 3. 6 v, a nickel metal hydride battery voltage is 1. 2 v, the latter three times. Lithium battery charging way is to set a terminal voltage, usually for a single nimh 4. 2v。 Lithium ion battery of battery charging method called voltage limiting current method ( Voltage is the voltage, flow refers to the working current, voltage, working current limits) Battery, and the working platform of nimh battery voltage is low, in general, choose constant current power supply ( Continuous working current) The battery. Considering the different methods of battery, lithium battery charger and nickel metal hydride battery chargers are not allowed to mix. 5. Specific models and specifications. At present, the common traditional nimh batteries often can be heard in the market, and rare lithium ion batteries are much rarer. This is to consider the current lithium ion battery is mainly in the market for the application of large capacity of enterprise products, if the application of small capacity of storage in the sales market, is not only a technical level, and split the cost is a big question 6. Daily: fill, fill it up with more than an hour. To prevent the middle of the night charge ( High power grid voltage) 。 Battery charging at any time, can be used for alarm or your phone. Should pay attention to when using a handheld machine battery as far as possible to recharge the battery in time, otherwise the battery self-discharge rate, voltage may fall again, may cause the self-locking protection rechargeable battery. Develop to work during the day, evening go home and start charging habits. 7. Options: under normal circumstances, the lithium ion battery can charge, use and stop. Cycle life is refers to the full set of frequency, part of the battery can be understood as several one-off service life. The key to select the battery: the battery is full of, can add the battery 20 minutes or so - 30 minutes to reach saturation, but it must be to prevent the battery after a long period of time. After a long period of time after the expiration of the battery can cause side effects, the result is to reduce the storage capacity and voltage meter resistance increased, often reduced storage capacity, phone call. PPC and other power supply chip machine, it is best to use until power is no longer charged, mainly considering power as a percentage of metrological verification. 8. For lithium ion batteries battery recharging after damage is very big, the battery again after expiration, battery internal cause side effects, active substance decrease, rechargeable lithium ion batteries battery charging anytime and anywhere
