Is the lithium battery plug of an electric bike better to be straight or curved?

What you want to ask is, is the lithium battery plug of an electric bicycle straight or curved? Bend a little better. The curved plug of the electric bicycle lithium battery can better adapt to various sockets and will not cause excessive bending of the wire and affect its service life. However, when inserted directly into the socket, there will be greater restriction and excessive bending of the wire. the wire will affect its lifespan. The electrical power of the straight head and the bent head is the same, so the bending is better.

How to distinguish lithium batteries from lithium polymer batteries?

Polymer batteryStrictly speaking, it is called "lithium polymer battery" (Li-polymer, also called lithium polymer battery): it is also a battery lithium-ion. battery A kind of battery, but compared to liquid lithium (Li-ion) battery, it preent many obvious advantages such as high energy density, smaller size, ultra-thin, light weight and high safety. In terms of shape, lithium polymer batteries are ultra-thin and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can achieve is up to 0.5 mm. Its rated voltage is the same as Li-ion 3.7V, and there is no memory effect.

“Lithium battery” is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries. Chemical properties of lithium metalLithium being very active, the processing, storage and use of metallic lithium are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream.

The main differences between the two are:

1. Polymer batteries do not have battery leakage problems. There is no liquid electrolyte inside the battery. uses solid state glue. Lithium batteries exist in liquid form

2. Polymer batteries can be transformed into thin batteries: with a capacity of 3.6 V 400 mAh, their thickness can reach 0.5 mm. Lithium batteries cannot be very thin

3. Polymer batteries can be bent and deformed: Polymer batteries can bend up to about 900 degrees.Lithium batteries cannot be bent or overbent

4. Polymer batteries can be made into single high-voltage batteries: Liquid electrolyte batteries can only obtain high voltage by connecting multiple batteries in series and polymer batteries.

5. Since the polymer battery itself does not contain liquid, it can be made into a multi-layer combination within a single cell to achieve high voltage.

6. The capacity of polymer batteries will be twice that of lithium-ion batteries of the same size.

1. Lithium-ion batteries and lithium-polymer batteries can be distinguished on the battery packaging label. Lithium-ion batteries are usually marked with the word Li-ion, and lithium-polymer batteries are usually marked with the word “Li-ion” Polymer word, as shown below. At the same time, as theElectrolyte of lithium polymer batteries is gel-like, there are fewer electrolyte leakage problems, so most of them are aluminum-plastic soft packaging.

2. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. It was invented by Edison. The reaction equation used by the battery is: Li+MnO2=LiMnO2. This reaction is an oxidation-reduction and discharge reaction. In the past, because the chemical properties of lithium metal are very active and the environmental requirements for processing, storage and use are very high, lithium batteries have not been used for a long time.

Lithium batteries are generally divided into two categories: lithium metal batteries and lithium ion batteries. THELithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than those of lithium-ion batteries.

3. Li-polymer battery (Li-polymer, also known as lithium polymer battery): Compared with previous batteries, it is a high-energy, miniaturized and lightweight chemical battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics and can be made into batteries of different shapes and capacities to meet the needs of certain products. The theoretical minimum thickness of this type of battery can reach 0.5 mm.
