With the iterative progress of technology, various electronic products have begun to appear, and batteries have gradually played their role.

In the smart lock industry, the choice and application of dry batteries and lithium batteries appear more frequently. Although from the perspective of the commercial situation of batteries, the application of lithium batteries is later than that of dry batteries, but today, with the gradual maturity of face recognition locks and video locks, with the gradual increase in power consumption, the market share of lithium batteries Has grown.

Therefore, we can inevitably imagine that as the smart lock industry continues to develop, products and functions continue to evolve and upgrade, and power consumption requirements are gradually increasing, will lithium batteries replace dry batteries in the power supply system of smart locks? To discuss this issue, you need to look at the choice of lithium batteries and dry batteries, as well as the market.

First of all, there are obvious differences between dry batteries and lithium batteries in terms of utilization and environmental protection.

Dry battery is a kind of voltaic battery. It uses some kind of absorbent to make the content into a paste that will not spill. Generally speaking, it contains heavy metals such as mercury and lead. Because it is a primary battery, it will be discarded when it is used up, which may cause battery pollution. .

There are many types of lithium batteries. The commonly used lithium batteries in the market include polymer lithium batteries, 18650 cylindrical lithium batteries, and square shell lithium batteries. Compared with dry batteries, lithium batteries are secondary batteries, and polymer lithium-ion batteries are more commonly used in electronic products such as mobile phones, household appliances, and notebooks.

In comparison, dry batteries are primary batteries, and lithium batteries can be recycled; lithium batteries do not contain harmful metals, so the pollution pressure on the environment is much lower than dry batteries; lithium batteries have a fast charging function and have a high cycle life. It is beyond the reach of dry batteries, and many lithium batteries now have protection circuits inside, which have a higher safety factor.

Secondly, the smart lock industry is becoming more popular and products are becoming more abundant. In the power supply system of smart locks, the proportion of lithium batteries is gradually increasing.

Since the 1990s, the domestic smart door lock market has roughly experienced the era of card hotel locks and password electronic locks, the era of fingerprint locks, the coexistence of multiple biometrics and the era of smart locks starting to touch the Internet, and the smart locks started in 2017. The era of artificial intelligence 4.0.

With the development of these four stages, the functions of smart door locks are becoming more and more integrated, and they are gradually developing from a single machine to a network. Single security verification is shifting to multiple door opening modes. The door locks continue to integrate more modules and functions. These changes have continuously increased the overall power consumption of the door locks. In the past, ordinary dry and alkaline batteries could not provide corresponding power support for a long time, making lithium batteries with higher energy density and long-term cycle charging become a trend.

In addition, compared with dry batteries, although lithium batteries have a higher replacement cost, lock companies still choose to configure lithium batteries for smart locks. There are also two reasons.

01. The realization of WIFI modules and even 5G modules, smart cat’s eye functional modules, and multiple unlocking modes required for smart door lock networking requires higher and higher power consumption. Lithium batteries can last for a long time under high power usage. The stable performance is a better power supply option. Frequent replacement of dry batteries will result in a poor user experience and the expansion of limited door lock functions.

02. The continuous improvement of the shape design of the smart lock requires a more flexible and compact internal space. The polymer lithium battery can achieve a larger battery capacity and unit energy density under a smaller size.

For the safety of lithium batteries that consumers worry about, the quality of battery products is actually guaranteed, and hidden dangers caused by external environments such as sub-zero temperatures or high fire temperatures can also be avoided.

Because smart door locks have strict design specifications, for the external environment temperature, the operating temperature of smart door locks will be between minus 20 degrees and 60 degrees. The function and parameter design of the lithium battery must also fully comply with the door lock itself. Product design requirements, and ensure the realization of parameter design from the process.

With the iterative update of smart door lock products, the change in demand for lithium batteries is reflected in the increase in battery capacity. At present, it is the mainstream trend to equip lithium batteries above 5000mAh. This is also in addition to the basic power consumption requirements. Smart lock products are built The necessary direction of differentiation and high-end positioning.

In addition, the versatility of lithium batteries is increasingly needed. General-purpose lithium battery products can effectively improve the quality of after-sales service and ensure that customers need to replace the lithium battery without causing a bad experience due to the difficulty of purchasing the lithium battery model.

Although the current market share of basic smart locks is still very high, and dry batteries should occupy a large area, with the gradual popularity of networked locks, video locks and face locks, and if manufacturers integrate more functions in their products in the future , In the future ultimate business state, the application of lithium batteries will become the first choice, even inevitable.

The smart lock industry and the battery new energy industry are still developing. Whether it is a smart lock brand company or a battery manufacturer, they should always regard their products as the primary productivity, understand the market and consumer demand trends, and seize opportunities in their respective fields. Do it to the extreme.
