Nexus 7 has recently become a market player, whether it's its internal hardware configuration or Android 4.1 system, making Nexus 7 one of the most competitive tablets available today. Walt Mossberg, the famous tech critic of the Wall Street Journal, gave a rather amazing rating after using the Nexus 7. The Nexus 7 is the best Android tablet of the moment, and some features even surpass the iPad.
Mossberg said that although the Nexus 7 is positioned differently than the iPad, it does not have the iPad's many features, such as lack of networking, no high-resolution screen resolution for the rear camera and iPad. And Nexus 7 (8GB version) has only half the memory capacity of the iPad, and the choice of music, movies, TV series and other content is not as rich as Apple and Amazon. But the Nexus 7 still has the ability to hit the iPad and Kindle Fire.
When using Nexus 7, Mossberg found that the Nexus 7's battery life was very good. Under the same test conditions, the Nexus 7's battery life was 10 hours and 44 minutes, while the iPad's battery life was only 9 hours and 45 minutes. The performance is even less ideal, and the battery life is only 5 hours and 47 minutes. The Nexus 7's battery life is nearly 45 minutes longer than the iPad, which is the first of all the tablets tested by Mossberg to surpass the iPad.
In addition, Mossberg believes that the Nexus 7 tablet also has the advantages of lower price, lighter weight and easy one-handed operation. The fluency of the Android 4.1 system has also tied the iPad. With an invincible price of $199, the Nexus 7 is undoubtedly the most affordable Android tablet available today.
Lithium Fluorocarbon Battery Of 18650
DADNCELL lithium fluoride battery (Li-(CFx)n) battery is a safe and stable battery system with an energy ratio of up to 2,400 wh/kg because of the positive electrodes used in CFC materials.
Fluorocarbon materials have stable physical and chemical properties and excellent high and low temperature operating properties. ≤600°C does not decompose, low temperature does not crystallize, and stable operation in a high and low-temperature environment at 20~125°C. The battery also has higher safety performance in short circuits, collisions, and compressions, and has explosion-proof and self-burning characteristics. At present, the whole series of products of the company's lithium fluoride batteries have passed the acupuncture test. Also, the lithium fluoride battery discharges only <0.5% per year, and the battery has a storage life of more than 10 years, at which time the battery can be thrown to save 95% of its electricity. There are no heavy metals and other pollutants in the production, use, and scrapping of batteries, which are green and environmentally friendly. All battery materials of DADNCELL batteries are independently developed and produced by the company, which can ensure the complete and long-term stable supply of the supply chain. Lithium fluoride batteries currently developed and produced by the company are applied on a large scale in fields with strict requirements for high and low temperature and high energy density, such as automobile tire pressure gauge (TPMS) batteries, industrial control motherboard batteries, computer motherboard batteries, smart instrument batteries, emergency equipment power supply for oilfield rigs, offshore rescue. Bioflash, implantable medical battery, etc.
The company can formulate DADNCELL lithium fluoride series battery solutions according to customer requirements.
