Compared with nickel-hydrogen batteries, we all know that, the following editor will briefly introduce you nickel-hydrogen batteries and lithium batteries. If you are interested in children’s shoes, take a look~~~ Your in-depth understanding of these two batteries will be very useful to you. Help~~~

NiMH-batterijen

Ni-MH battery is composed of hydrogen ion and metallic nickel. Its power reserve is 30% more than that of nickel-cadmium batteries. It is lighter than nickel-cadmium batteries, has a long service life, has a large environmental pollution, and has no recall effect. The disadvantage of nickel metal hydride batteries is that nickel cadmium batteries are more expensive than lithium batteries.

lithium batterij

Lithium battery is a battery invented by Thomas Edison. It uses lithium metal or lithium alloy as the positive electrode material and uses a non-aqueous electrolyte solution. The battery operation reaction equation is Li+MnO2=LiMnO2. The reaction is divided into oxidation-reduction reaction and discharge reaction. In the past, lithium batteries have not been widely used due to their unique chemical properties, high requirements for processing, storage and application, and high requirements for the environment. With the development of modern science, lithium batteries have become the mainstream.

volume

Compared with ordinary nickel-cadmium/nickel-metal hydride batteries, rechargeable lithium batteries have the advantages of small size (relatively), light weight, low self-discharge rate, no recall effect, etc., and have been widely used in many new mobile devices. Lithium batteries have gradually replaced batteries in mobile devices such as mobile phones, notebook computers, and handheld computers. The memory effect of the nickel metal hydride battery is not very obvious. One thing is that it is urgently needed and does not need to be charged by photoelectric. Generally, it is best after sufficient light.

Elektriciteit

Lithium battery has high specific energy and good battery performance. The voltage of a single lithium battery is three times that of a nickel-metal hydride battery. There is no recall effect, it can be used and recharged. But it cannot be used for charging, so charging and discharging too many times will affect the battery life. Lithium batteries are not suitable for long-term storage, and long-term storage will permanently lose part of their capacity. It is best to charge 40% electricity and store it in the freezer of the refrigerator.

laadmethode

The charging requirements of lithium batteries are different from ni-CD/ni-MH batteries, ni-CD/ni-MH batteries are rechargeable lithium batteries with a single voltage of 3.6V (some batteries may be marked as 3.7V). As the power supply overflows, the voltage of the lithium battery gradually increases, which is also a sign to determine whether the lithium battery is overcharged. The general manufacturer recommends a charging voltage of 4.2V (single lithium battery). Generally speaking, lithium batteries are charged by limiting voltage and current. If you want to charge the lithium battery separately, it should be noted that the charging method is different from the constant current charging method of the nickel-cadmium/nickel metal hydride battery, and the nickel-cadmium/nickel metal hydride battery charger cannot be used.
