LR1130 battery

Mobile phone LR1130 battery encounter bottlenecks, can wireless charging be used?

In recent times, there have been constant reports of major technology companies upgrading their hardware performance equipment. Whether it is MediaTek's true 8-core processor MT6592, which was the first to be launched, or Qualcomm's latest flagship product Snapdragon 805, which will soon follow, or LG Electronics' new Odin processor that will test the chip field, these have made next year's mobile phone performance parameters have some new highlights. However, while the computing and processing performance of mobile phone chips is getting stronger and stronger, we cannot ignore the fact that the hardware performance has been greatly improved. Can the small battery built into the mobile phone keep up with the development pace of the former?

After all, for ordinary users, the most ideal product is a balance between performance and battery life. If the hardware performance of the mobile phone is only improved, where will the user experience be if the battery life is shortened? It is no exaggeration to say that now, whether it is the Android camp or the iPhone series, most of the mobile phones can only last less than a day under moderate or heavy use. If you want to use it for a long time, the only options are to replace the backup battery or use a mobile power bank, which are superficial solutions that only treat the symptoms but not the root cause.

Moreover, the performance improvement of most products represented by mobile phone LR1130 battery is not like the integrated circuits described by Moore's Law, which will double every 18 months and double the performance. So when the improvement of hardware performance is far ahead of the development of mobile phone battery technology, can we seek breakthrough solutions in other ways, such as wireless charging?

Bottlenecks in battery technology

Although many technology companies have invested heavily in the research and development of various battery technologies, the distance between laboratory results and widespread commercial use is not as far as we guess. What's more, it is basically impossible for a revolutionary breakthrough in mobile phone battery technology in the short term, so the solutions that major battery manufacturers can currently adopt for mobile phone LR1130 battery are nothing more than modifying and improving various electrode materials inside the battery.

As for the room for improvement of lithium LR1130 battery, judging from the annual rate of improvement of the parameters of mobile phone hardware performance, even if the energy density of lithium LR1130 battery can be theoretically improved by 5-8% each year, this little improvement is like a drop in the bucket when facing high-performance processors, large-size high-definition screens and other power-intensive devices. Unless the architecture of the battery itself can be changed in new technologies, there is no way to break through the limit of capacity.

In the field of mobile phone LR1130 battery, it is very difficult to develop a new material and successfully achieve commercial and industrial use. Perhaps this goal will not be achieved in the next few years. Take the fuel cell, which we have been calling for, as an example. Not only is it difficult to achieve technical implementation, but also because of the required catalyst, the actual commercialization cost is also extremely high. Therefore, fuel cells have not been widely used in practice for decades since their invention. Moreover, if the so-called fuel cell is to be applied to mobile devices, the difficulty of simplifying its system integration is much greater than that of lithium LR1130 battery or other types of rechargeable LR1130 battery that are currently fully integrated.

Application of wireless charging

For the current trend of mobile devices tending to be integrated, the fact that mobile phones can replace LR1130 battery is getting further and further away from us. Faced with the dilemma of battery technology development encountering bottlenecks, it is expected that we will rack our brains to pursue the increase of battery capacity. It is better to consider how to adopt a new model to solve the actual power supply problem of mobile phones. In addition, if the mobile phone wants to ensure long-term use, charging anytime and anywhere can alleviate our demand for battery capacity to a certain extent.

For example, the wireless charging technology that has gradually developed now is like this. This is actually similar to the concept that each of us has limited computer hard disk space, but can save files through cloud storage. Unlike the cumbersome and inconvenient USB data cable charging, the development of mobile phone wireless charging can naturally get rid of the troubles brought by wires like wireless Wi-Fi, and provide charging convenience anytime and anywhere. It can indeed have a good development prospect before the new battery technology comes out.

At the same time, for wireless charging, although the implementation principles are similar, they are different in transmission methods and have their own strengths. At present, the actual commercial use is more electromagnetic induction wireless charging technology, such as the wireless charging method represented by Lumia920 and Nexus4. As for the wireless charging technology based on the principle of magnetic resonance, although it can theoretically meet our expected long-distance and high-power wireless charging needs, this, like the battery technology mentioned above, is still in the laboratory stage for more technological breakthroughs, so it will take some time for commercialization.

The reality of wireless charging

But the same problem is that even now wireless charging has begun to be applied to the field of mobile phones, but for the wireless charging of the Qi standard that we are familiar with, it still has many shortcomings that need to be improved. For example, the conversion rate, although the current theoretical wireless charging efficiency is said to be able to reach a range of 75%-80% of wired charging, that is, about 1/5 to 1/4 more time than the latter in charging time, so the actual differentiated experience may not necessarily be superior to the latter. However, the advantage of wireless charging is that the mobile phone can be charged in more fragmented time, and we will find that it actually saves a lot of time dedicated to charging the mobile phone.

Not only that, the current maturity of wireless charging does not support the mobile phone to leave the charging base at a long distance, so our vision of charging and playing with mobile phones without obstacles is temporarily unfulfilled. In addition, the compatibility between the additional wireless charging base and different wireless standards has greatly reduced its ease of use in different environments. Even the electromagnetic induction charging, which is the most mature and commercially easy to achieve now, has imperfections such as low conversion rate between devices, additional wireless charging coils increase the complexity of the mobile phone body, limited distance and the mobile phone must be placed on a specific base when charging, so it also brings many inconveniences in experience.

So for these points, although wireless charging has its own advantages, it is obviously still in a very basic stage. But fortunately, there is a lot of room for improvement in maturity, and it is faster and more practical in commercial use than developing battery technology. If the wireless charging standards formulated by major technology alliances can be unified, improved and standardized in the near future, and promote the infrastructure of wireless charging, it will be able to promote the development of this industry more quickly. Then it means that wireless charging will be more widespread, and perhaps free wireless charging will be a new way to attract customers in places like coffee shops and McDonald's where free Wi-Fi is provided.

In the end, if you want to extend the battery life of mobile phones in the short term, you may still have to rely on the efforts of the entire industry to reduce power consumption.
