A battery is a device that converts energy produced by chemical reactions directly into electrical energy. It has the characteristics of stable voltage, stable current, stable power supply for a long time, little influence from the outside world, simple structure, easy to carry, simple and easy charging and discharging operations, stable and reliable performance, and brings a lot of convenience to modern social life.
In recent years, mobile electronic device technology has developed rapidly. More powerful processors, graphics cards, ultra-clear and even flexible screens are all impressive. Unfortunately, breakthroughs in battery technology have been slow, and we still have to endure a day or so of battery life. Although we have been paying attention to the development of new material batteries, in fact, it is lithium battery technology that is most likely to achieve breakthroughs in the near future. Next, let’s take a look at the development of next-generation battery technology.
Traditional lithium-ion batteries using graphite anodes can only achieve an energy density of less than 600Wh/L; advanced silicon anode batteries only achieve an energy density of 800Wh/L, while ultra-thin lithium metal anode batteries can exceed an energy density of 1000Wh/L. Although many current lithium metal anode batteries such as lithium air and lithium sulfur batteries are still far from practical applications, Massachusetts Solid Energy Company used mature lithium cobalt oxygen cathodes to successfully achieve an energy density of 1337Wh/L on a 2Ah battery cell. , and will be applied to consumer electronics products on a large scale in 2016.
It is understood that the aluminum-ion battery developed by scientists this time has perfect properties and does not have the risk of explosion like some other battery products. It can be charged up to 7,500 times and can be fully charged in just 1 minute. In the test, the aluminum battery went through more than 7,500 charge and discharge cycles without loss of capacity.
Li Zhenqiang, CEO of Qidian Research, said at the meeting that from the perspective of China’s lithium battery competition landscape, industry concentration is far lower than abroad. In 2015, the global market concentration rate of the top 10 Chinese lithium batteries was 44.4%, and only one of the top 10 companies was not involved in power batteries. Li Zhenqiang predicts that China's lithium-ion battery market will reach 96.11GWH by 2018, with a compound growth rate of 25% in the next three years, EVs will maintain a compound growth rate of more than 40%, and the ESS market is expected to explode in 2018.
Batteries store specific energy and then release it at the appropriate time. Many data center equipment professionals are frustrated by the inconsistent performance of their batteries. When asked, “Does data center infrastructure need improved energy storage solutions?” data center operators, users, and staff always respond in the affirmative.
The "star" has fallen, and the energy storage industry is crying out. For all intents and purposes, Aquin Energy seems destined to succeed.
Recently, three of the world's top battery experts from Argonne National Laboratory and Northwestern University published a paper discussing the development process of chemical energy storage batteries and making predictions about the development prospects of lithium batteries. They believe that it is achievable to increase the energy density of lithium batteries by 2-3 times in the future, and the key lies in the innovation of battery materials.
As the usage time of the mobile phone increases, the maximum capacity of the mobile phone will gradually decrease, so that the battery of the mobile phone may run out of power in half a day. However, as long as we replace the mobile phone battery, the mobile phone can last for another two years, so replacing the battery to extend the life of the mobile phone has become the first choice for most users. Compared with the official cost of replacing a mobile phone battery, which can easily cost hundreds of dollars, it is much cheaper to replace the battery by a third party or yourself, and now Apple has taken measures to replace the battery by a third party.
