Everyone must have purchased a domestic cell phone battery. Most people buy a domestic cell phone battery because its capacity is one or more times that of the original battery. But why can a home battery significantly increase its capacity without increasing the capacity. size much? What about increasing battery capacity? Is it true that domestic battery manufacturers are so NEWBEE that they master technologies that foreigners don't understand? The lithium ions in a lithium-ion battery can be divided into two parts. One part is responsible for storing and transporting electrons during daily cell phone use. They can be called functional lithium ions. Functional lithium ions will continue to store and transport electrons. During daily use, in case of loss ofearth, another part of lithium ions is needed to complete. This part of lithium ions as backup can be called additional lithium ions. These two parts of a good lithium-ion battery are essential, but many household batteries. Manufacturers have sacrificed lithium ion replenishment to achieve high capacity. On the surface, this makes consumers feel that the battery has large capacity, is convenient to use, and the price is much more economical than the original battery, but this is not the case among consumers . realize how much of its capacity is achieved at the expense of battery life. Additionally, lithium ions also have a lifespan of one to two years. During this period, as long as the mobile phone is not too discharged or overcharged. The battery life of the mobile phone will be limited. It is shortened by the number of charging times. When you buy a new mobile phone, it is wrong to charge the mobile phone battery for more than 10 hours in order to activate the lithium ions. It is wrong to charge the mobile phone for such a long time as overcharging, because the mobile phone has activated the lithium ions in the battery before leaving the factory and has pre-stored energy to maintain its activity. many people like to use battery power and then charge it. This is also not considered excessive discharge. Generally speaking, it is better to use the original cable charger when the battery lasts 10-30 seconds. the phone indicates that the battery is full, we can stop it!
These two types of batteries have differences in energy density, volume and weight, service life, charging and discharging characteristics, environmental adaptability, price and protectionn of the environment.
1. Energy Density: The energy density of lithium batteries is typically 200-260 Wh/kg, while the energy density of lead-acid batteries is around 50-70 Wh/kg. This means that lithium batteries can provide more power for the same weight.
2. Volume and weight: The volume and weight of lithium batteries are generally smaller and lighter than lead-acid batteries. The volumetric capacity density of lithium batteries is about 1.5 times that of lead-acid batteries, so with the same capacity, the volume of lithium batteries can be about 30% smaller.
3. Lifespan: The lifespan of lead-acid batteries is generally around 2 years, while the lifespan of lithium batteries is generally 4-5 years or more. The number of complete charge and discharge cycles of lead-acid batteries is generally lowerto 300 times, while the number of complete charge and discharge cycles of lithium batteries can exceed 500 times.
4. Charging and discharging characteristics: Lithium batteries have no memory effect and can be charged and used at any time, while lead-acid batteries need to be charged after the power runs out.Avoid memory effects .
5. Environmental adaptability: Lithium batteries generally perform better than lead-acid batteries in extreme temperatures and can operate over a wider temperature range.
6. Price: Lead-acid batteries are generally more affordable than lithium batteries, but the long-term operating costs of lithium batteries may be lower because lithium batteries have a longer lifespan.
7. Environmental protection: Lithium batteries are generally considered more environmentally friendlyes environmental than lead-acid batteries, because lithium batteries do not contain lead, a toxic heavy metal.
When selecting a battery, you must decide which type of battery to use based on specific application needs, budget and environmental factors.
