Preface
With the advancement of technology, the functions and performance of mobile phones are getting better and better. In order to stabilize the battery life, the battery is also designed to be bigger and bigger.In order to enhance the battery life, some manufacturers have adopted a dual battery design, but still cannot solve the symbiotic problem of battery life and portability, in the case that the capacity cannot be increased, mobile phone manufacturers began to shift their target to the wired fast charging above, at the time of the sudden progress of wired fast charging, some manufacturers began to develop both convenient and aesthetically pleasing wireless fast chargers based on the requirements of some users, eventually forming a new wireless charging industry cluster, making it more convenient for people to travel and replenish their batteries, while reducing the use of a large number of wire harnesses and helping the concept of green travel and carbon neutral development.
The 2022 Qatar World Cup has set off a wave of football fever, and the exciting tournament has become a spiritual companion for many "night watchers", as they watch the World Cup, radio technology has quietly entered their line of sight. This is because Al Rihla, the official ball of the World Cup, is powered by a small battery and is charged wirelessly for better design, sealing and stability. The wireless charging device provides the official ball of the World Cup with a powerful power supply.
Developments and Trends in Wireless Charging
Since 2009, wireless charging technology was first installed on mobile phones PALM and amazed the world, but since then the development has been silent, like a dream, in the eyes of the world but a flash in the pan. Time came in 2017, Apple's new fall conference, the first announcement of the new iPhone 8 series will use wireless charging technology, since then opened up the blueprint of Apple's wireless charging ecological layout, to facilitate the user's daily replenishment of electricity. Wireless charging technology began to emerge in the field of mobile phones, leading to the development of wireless charging in cars, smart homes, robots, drones and other areas of application.
Nowadays, cities are moving towards a "fast" pace of life, with people seeking higher time management and a higher utilization rate of trivial time, leading to a shift towards smaller and more efficient wireless charging devices. In response to this trend, leading wireless charging companies are developing the next generation of higher power, longer range and higher efficiency wireless chargers to suit consumer needs and enhance the consumer experience.
Hard-Core Capacitor Requirements for Wireless Charging
The advantages of wireless charging dictate high requirements for capacitors. Firstly, wireless charging is simple and beautiful without the winding of wires. This requires smaller and thinner capacitors. Secondly, the mentioning of nimbleness and portability plus the complexity of the working environment requires capacitors to have the hardcore property of ultra-high power while being small in size. Thirdly, in technology development, capacitors performance is the "throat" that restricts the further development of wireless charging.
At present, the capacitors commonly used in wireless charging devices for the iPhone are multilayer ceramic capacitors, but they cannot break through the bottleneck of "smaller size and thinner thickness". At the same time, due to their own material limitations, they inevitably suffer from whistling and piezoelectric effects, and are unable to adapt to the new requirements and high demands of wireless charging technology solutions.
Therefore, YMIN Capacitorhas been researching towards the direction of ultra-thin size and higher power capacitors to develop a "new capacitor" with better adaptability to wireless charging solutions. After unremitting efforts, YMIN Capacitorhas finally developed Multilayer Polymer Laminated Aluminum Solid ElectrolyticCapacitors and Polymer Aluminum Solid ElectrolyticCapacitors with small size, high energy and high stability that meet the above requirements. Considering that some special and smaller wireless charging solutions require finer capacitors, we have developed even smaller size A case and B case polymer tantalum capacitors.
YMIN Capacitor Advantage
With the advantages of small size, high energy and high stability, polymer solid-state chip capacitors are widely used in higher power supplies, industry and communication power supplies, allowing manufacturers in different fields to choose different capacitors according to different conditions.
