Battery memory effect and type analysis

1. The memory effect of the battery The battery memory effect refers to the spontaneous energy loss accumulated by the battery over time, referred to as self-discharge. This phenomenon is caused by spontaneous redox reactions, and no matter what the electrochemical system is, all types of batteries are inherent. Regarding the quantitative evaluation of self-discharge, the value of energy lost by the battery over a period of time is expressed as a percentage of the value just after charging. It is expected that the cargo will be unloaded on its own in the first 24 hours after the billing, so it is expected to be the same on the first day and the first month of the billing. The self-discharge of the battery depends largely on the ambient temperature. Therefore, if the temperature rises above 100°C, self-discharge can be doubled. The figure below shows the impact of the battery memory effect. Memory effect 2. Battery types Today, there are many different battery designs on the market, and each battery manufacturer strives to achieve a combination of high capacity, small size and weight, wide temperature range and performance, and the best characteristics under extreme conditions. At the same time, the study stated that more than 65% of mobile and handheld device users are willing to pay more to get more opportunities to use the device for a few more days without charging. Therefore, in most cases, you will want to buy a battery with a larger battery capacity. According to the electrochemical system, batteries are divided into several types: sealed lead-acid batteries (SLA); nickel-cadmium batteries (Ni-Cd); nickel-hydrogen batteries (Ni-MH); lithium batteries (Li-Ion); lithium polymer batteries (Li-Po); Fuel power battery. In modern portable electronic devices, lead batteries are no longer used and will begin to be used and used in nickel batteries for cameras, laptops, camcorders and other devices.
