Global mobile phone industry, the international financial crisis dragged down into the negative growth period, amid the economic downturn continued weakness in consumer spending, with sales followed a substantial decline, leading to a drastic shrinkage of the global handset industry profits. International Data Corporation predicted that the financial crisis, the global handset market in 2009 will appear the first time since 2001, shrinking.
Global mobile phone industry suffers an economic cold, a lot of impressive past achievements of international mobile phone brands have set back the battlefield. When the international mobile phone brands was devastated when no longer glorious past, sony vgp-bps5a battery,domestic mobile phone is being ushered in new opportunities. When consumers live Wujin purse when the pursuit of the concept of the brand after the station has been relying on, practical purchase price of a mobile phone the primary factor, but it is cheap and high quality Chinese-made mobile phones are good at. Financial crisis for the international mobile phone brands is a disaster for China’s mobile phone industry is the expansion of opportunities.
In the recently concluded 2009 Tianjin International Mobile Phone Industry Exhibition, Tianyu Lu Wei Bing, general manager of GSM Division, said the crisis era of the global handset market is quietly changing the pattern of emerging markets a growing share of China’s mobile phone brands are fully into the world. At present, the Sky lanton among the three major mobile phone brands in China ranks second only to Nokia, Samsung. Following the 2008 to go abroad to enter the Southeast Asian market after the 2009 Tianyu successfully entered the Middle East, South America and other markets. According to Lu Wei Bing introduction, is now overseas month Tianyu has shipped over 60 million, and overseas sales are still in rapid growth.
Chinese mobile phone brands stand on the world stage of confidence also comes from China in early 2009, the official issuing 3G licenses, especially the Chinese standard TD-SCDMA development is thrown its weight behind the government.
Tianjin mobile phones in this exhibition, in addition to Motorola, Samsung demonstrated the 3G mobile phone, the Sky lanton also introduced several of 3G products. Lu Wei Bing said: “The days will launch a variety of languages TD products at a reasonable price would be 3G product promotion to more consumers, but also reduce operating subsidies for the cost of a single provider for China’s TD industry to make our contribution to the prosperity of . Over the next six months time, we may have 8 to 10 models will launch TD products. ”
Mobile Internet applications blowout birth, battery-powered hard-pressed
Mobile value-added services has doubled, mobile devices, as well as how to support 3G mobile value-added services 3G power to become one of the main terminal. From 2G into 3G era, mobile phones that are hosted by more than a simple call feature, which combines phone, photography, video, navigation, data transmission, audio and video playback, send and receive mail, browse the web in one multi-functional. Bluetooth, WiFi, GPS, mobile TV and other functions a significant increase in RF, baseband and then pulled the working hours of system power consumption; video telephony, mobile TV, JAVA games and multimedia features are increased application processor computing load; the pursuit of super - screen, high resolution, thereby increasing the display and the surrounding power system, the burden of backlight. Set aside and 3G phone than 2G/2.5G increase in power consumption at 35 ~ 40%, single-function has been enough to make all kinds of fancy mobile phone battery stretched beyond their limits.
Phone standby time and talk time a consumer calls to measure the performance of their most basic criterion, once the standby time can not meet consumer habits, high-quality user experience to speak of, it is difficult to attract users from 2G network to 3G network migration. Therefore, the battery issue has become the biggest problem on the road to expand 3G.
The above-mentioned phone functions demand the battery capacity to achieve a breakthrough to ease the mobile power needs are met, in order to ensure adequate standby time. On the other hand, due to the integrated phone functions requiring battery voltage is always maintained at a relatively high voltage level. Recently, an accident caused by the battery in use has proclaimed: Dell laptop in the conference room fire, explosion, explosion-induced deaths in Gansu mobile phone is even more shocking, so against the use of mobile phones becoming increasingly common in the social situation, the safety of lithium-ion battery Performance is very important. In addition, consumers also want a longer battery life requiring the battery charge and discharge cycles more frequent.
At present lithium battery can be divided into two categories: liquid lithium-ion battery (LIB) and polymer lithium-ion battery (PLIB). Liquid lithium batteries in the case of overcharging easily rupture triggered a fire must be installed to prevent the overshoot protection circuit, and even so are still buried in fire hazard. The solid polymer lithium battery charge and discharge characteristics of resistance than the liquid lithium batteries is more safe and reliable. And the polymer lithium battery lithium battery unit energy than the average 50% higher, in terms of safety, capacity, operating temperature, cycle life and other terms, which are ahead of liquid lithium batteries.
Shenzhen B & K Battery Co., Ltd. Li-polymer batteries Division held in the same period CAO Jian, general manager of China Mobile Phone Industry, 2009 (International) Summit Forum to play a period of solid-state lithium battery using scissors cut the video, after the destruction of lithium batteries does not appear leakage, no smoke and other combustion phenomena, and even continue to work (keep the connection between the sony vgp-bpl5a battery,sony vgp-bps2 battery positive and negative).
“Solid and liquid lithium-polymer battery cell is that the biggest difference between the solid polymer electrolyte inside the battery does not, while the electrolyte is an organic solvent, is a flammable chemical raw materials, non-use of the electrolyte can be said that fundamentally reduce the lead to the probability of burning lithium battery lead. This essentially determines the safety of lithium batteries, as long as the fire is not burning inside, it would not have exploded. “CAO Jian further information on the characteristics of solid-polymer battery, said,” solid-state polymerization the volume ratio of the energy lithium battery materials can reach 450Wh / H, while the cycle life of up to 500 times, 300 times in the charging and discharging, the capacity retention rate was 98%, this indicator is far higher than the current liquid lithium batteries. ”
Currently there is the ability to produce solid polymer lithium battery company in Shenzhen B & K alleged that only one, which broke the monopoly of Japanese giant, solid-state polymer batteries battery situation. This is currently trying to go abroad to launch high-end mobile phone manufacturers, is undoubtedly a good news. Shenzhen B & K through the independent research and development, solid-state polymer sony vgp-bps2a battery,sony vgp-bps3 battery holds the intellectual property, enabling the domestic mobile phone enterprises overseas for less than the price of lithium batteries using solid polymer batteries for mobile phones to reduce indirect costs.
Personalized cell phone era, custom cell surface
Cell phone lithium battery into the 3G era has also made a number of specialized requirements. Apple pioneered the first of its kind cell phone built-in battery, iPhone style iPod inheritance will be solid-state polymer lithium battery built into the phone. Since the battery can not be replaced, there is no backup battery to add the possibility of electricity, while the cost of replacing the battery up to 75 dollars, so the battery capacity and life request a more demanding than ever.
According to CAO Jian introduction, B & K in addition to custom high-capacity, long-life lithium batteries, it can also resistant to high temperature for the battery to conduct a research and development, to ensure that the sony vgp-bps3a battery,sony vgp-bps5 battery in the tropics, special high or low temperature environments may also work. In addition, underground mine communications, military and communications applications also require high-security cell.
