Lithium Ion
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nokia 3310
The Nokia 3310 is a GSM mobile phone announced on 1 September 2000, and released in the fourth quarter of the year, replacing the popular Nokia 3210. It sold very well, being one of the most successful phones, with 126 million units sold worldwide, and being one of Nokia's most iconic devices. The phone is still widely acclaimed and has gained a cult status due to its reputation for durability. Several variants of the 3310 have been released, including the Nokia 3315, 3320, 3330, 3350, 3360, 3390 and 3395. The Nokia 3310 was produced at factories in Finland and Hungary. The 3315s were produced in South Korea for the Asia-Pacific market. A new mobile phone based on the 3310 design was launched in 2017. The new Nokia 3310 model comes with a comprehensive update over its predecessor, with a 2.4" color display, a 2 Megapixel rear camera and a microSD slot. Design The 3310 was developed at the Copenhagen Nokia site in Denmark and unveiled at the "Don't be bored. Be totally bo ...
