What Kind of Battery Is a 1.5V Lithium Battery? What Are the Advantages of 1.5V Lithium Battery?


At present, there is a 1.5V lithium battery on the market, which is a reusable rechargeable battery. Models are AA and AAA, and the size of the battery is the same as that of alkaline batteries AA and AAA. The 1.5V lithium battery is a rechargeable lithium battery with a constant voltage of 1.5V throughout the process and no voltage drop. It uses 3.6V lithium battery inside. Through the internal circuit control, the output voltage is 1.5V. It has the characteristics of strong power and is especially suitable for all kinds of electrical appliances with high current and high voltage requirements.

Alkaline and carbon-zinc batteries have been the workhorses of household disposable batteries. NiMH batteries have always been the main force of household rechargeable batteries, especially the two types of AA and AAA, which are widely used. However, with the development of science and technology and the application of many products, alkaline and carbon-zinc batteries have low capacity, rapid voltage drop, and are not suitable for extreme temperatures. Disadvantages such as low platform discharge have also begun to appear. So after research and development, a new 1.5V lithium battery appeared, that is, the 3.6/3.7V lithium battery is stepped down to 1.5V constant voltage output through the built-in circuit module.

#2-What Are the Advantages of 1.5V Lithium Battery Compared With Traditional Alkaline Batteries, Carbon-Zinc Batteries and Nickel-Metal Hydride Batteries?


①The whole process is constant voltage 1.5V, and the output is stable

The fully charged NiMH battery was put into the toy racing car, and the racing car was whirring and full of power at the beginning. After a period of use, the performance of the car will gradually weaken, until it finally becomes weak. The reason for this is that during the discharge process of traditional nickel-metal hydride batteries, the voltage will continue to weaken, and the dynamic performance of the car will also weaken.

In contrast, the current industry’s 1.5V lithium battery output is a constant voltage of 1.5V. You can simply understand its discharge voltage as a horizontal straight line. On this straight line, due to the constant voltage, racing cars, remote controls, toy cars, etc. using the battery will also maintain stable performance as always.

② long life, no memory effect

Compared with nickel-metal hydride batteries, lithium batteries have no memory effect, which is a great breakthrough. If the traditional nickel-metal hydride battery is not deeply discharged for a long time, the capacity of the battery will become smaller and smaller, and the battery life of the corresponding battery will also be greatly reduced. There is no such concern when using lithium batteries. You can charge and discharge your lithium battery at any time, and shallow charging and shallow discharging can even reduce battery wear and tear.

Although many manufacturers promise that their nickel-metal hydride batteries can be used 500 times. However, due to the existence of memory effect, players need to fully charge and discharge the battery from time to time to release the capacity of the battery – which is bound to greatly reduce the battery life. In contrast, 1.5V lithium battery life depends on lithium battery cells. For example, XTAR’s upcoming 1,.5V lithium battery uses internationally renowned cells, and after 500 uses, there is still ≥80% of the remaining capacity.

Because of the high density of lithium batteries, the battery energy of AA lithium batteries is higher than that of Ni-MH batteries. Next, the voltage platform of AA lithium batteries is 1.5V, while that of Ni-MH batteries is 1.2V. The operating voltage platform is higher than that of Ni-MH batteries, etc. .

③It is with all the advantages of lithium battery

Since the 1.5V lithium battery is stepped down through the 3.6/3.7 lithium battery. Lithium batteries have all the advantages, such as fast charging speed, low self-discharge rate, high safety performance, large discharge current, excellent high and low temperature discharge performance and so on.

For example, AA lithium batteries usually only take 3 hours to fully charge four AA lithium batteries. In addition, the AA lithium battery supports 1000 cycles of use. According to the official experimental data, the remaining capacity of the battery is greater than 80% after 500 cycles, and the remaining capacity after 1000 cycles is greater than 60%, which greatly extends the service life of the product.

④AA lithium batteries are rechargeable batteries, but they are no different from conventional AA batteries in appearance parameters, so there is no need to worry about compatibility issues. The 1.5V AA lithium battery is compatible with all devices that use AA batteries. If it is more suitable to match, it is more suitable for devices that need to be used frequently, such as camera flashes.

As the technology matures, the cost factor that mainly restricts the development of 1.5V lithium batteries will gradually weaken. The advantages of 1.5V lithium battery have gradually become prominent. With the emergence of more high-power small appliances, 1.5V lithium battery has a lot of room for development in the future. Will the household secondary battery be the world of 1.5 V lithium battery in the future? Welcome to communicate.
