Both are good, but their scope is different.
A dry cell is a type of voltaic cell in which an absorbent (such as sawdust or gelatin) is used to transform its contents into a paste that cannot be spilled. Used as a power source for lighting flashlights, radios, etc.
Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. It is different from rechargeable batteries, lithium-ion batteries and lithium-ion polymer. batteries. Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries.
Lithium-ion batteries do not contain lithium in a metallic state and can be recharged. Dry batteries contain heavy metals likee mercury and lead. Since it is a primary battery, it will be thrown away after use, which can easily cause battery contamination. Lithium batteries do not contain harmful metals. Lithium batteries have fast charging capabilities and long life, a level that dry batteries cannot achieve.
Whether dry batteries or lithium batteries are better for electric vehicles
Dry batteries are primary batteries in chemical energy sources and are disposable batteries. Since the electrolyte of this chemical device is a non-fluid paste, it is called a dry battery, as opposed to a fluid electrolyte battery. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The first lithium battery came from the great inventorr Edison and used the following reaction: The main difference is that the reaction materials of the power supply are different and the characteristics are different.
Lithium battery. Here is a comparison of whether electric vehicle dry batteries or lithium batteries are better:
1. Lithium batteries are the battery type with the highest energy density among existing mature battery types.
2. Dry batteries have low capacity and are not suitable for occasions requiring large current and long-term continuous operation. Additionally, there is a lot of wastage of raw materials.
