1. Different definitions: battery is a device that directly converts chemical energy into electrical energy, and it is a battery designed according to rechargeable; Lithium battery is a battery with lithium metal or lithium alloy as anode material and non-aqueous electrolyte solution;
2. The working temperature range is different: the working temperature of the battery is 20 to 25 degrees Celsius, while the working temperature of the lithium battery is - 20 degrees Celsius to 60 degrees Celsius;
3. Different applications: lithium batteries are used in mobile phones, computers, power tools, UPS power supply and other equipment. The battery is used in automobile starting and electric vehicle battery;
4. The charging and discharging aspects are different: the battery has memory effect, so it cannot be charged and discharged at any time; There is serious self discharge; Lithium battery has no memory effect, so it can be charged and discharged at any time and stored for a long time;
5. Different safety performance: lithium battery comes from the stability of cathode material and reliable safety design, which will not explode even in severe collision; The battery will explode under strong collision;
6. Different green environmental protection: lithium battery materials are green and environmental friendly without any toxic and harmful substances; However, there is a large amount of lead in the battery, which will pollute the environment if it is improperly disposed after being discarded;
7. The internal materials are different: the positive and negative electrodes of lithium battery are lithium cobalt oxide, lithium iron phosphate, lithium manganate, graphite and organic electrolyte; The positive and negative electrodes of the battery are lead oxide, metal lead, and the electrolyte is concentrated sulfuric acid;
8. Different functions: the function of the battery is to supply power to the engine, and to power the lighting, sound devices and ignition system when the engine power generation is insufficient; The function of lithium battery is to store electricity;
9. Different discharge characteristics: for the same fully charged lithium battery and battery, at the same temperature, with different discharge current ratios, the discharge output characteristics of lithium battery are very stable, while the discharge output characteristics of battery are very different, which will cause power instability;
10. The composition structure is different: the battery is mainly composed of shell, cover, filling hole plug, connecting plate, connecting column, plate separator and electrolyte; The five components of lithium battery structure include: positive pole, diaphragm, negative pole, organic electrolyte and battery shell.
