According to foreign media reports, this week, the inventor of the vacuum cleaner, the British company Dyson (Dyson) founder James Dyson completed his first pen of foreign investment, the solid-state batteries Sakti3 company invested 15 million USD. Sakti3 said its solid-state battery technology is expected to bring cheaper and more energy density batteries.
Dyson investment Sakti3, designed to help the company to commercialize its solid-state battery technology - eventually apply to Dyson products.
But what is a solid-state battery technology, the other is being developed that allows smart phones, cordless vacuum cleaners and electric vehicles have a longer life battery technology have? Below these technologies to make a brief introduction.
Solid-state battery
is a battery composed of an electrode and an electrolyte. In general, the electrode is a metal conductor, the electrolyte is a liquid. As the name suggests, the solid-state battery using a solid electrolyte.
Solid-state battery eliminates any fluid leakage problems, and can be miniaturized. This is Sakti3 technology being developed. But the technology has not yet commercialized, it tricky is that improving the production process, rather than the development of the theory - the theory has been perfect, but to reduce the cost of production is not very easy.
Sakti3 claims to have manufactured the energy density of 1.1 kwh per liter of battery, the energy density than lithium-ion battery is about 50% higher, but the data has not been independently tested.
Lithium-ion batteries
, lithium ion batteries have been widely used in most consumer electronics and electric vehicles. The battery electrolyte is a flammable liquid, so if the battery is damaged, can be dangerous.
Lithium-ion battery concept as early as the 1970s had already been made, but until 1991, Sony and Asahi Kasei (AsahiKASEI) just launched its first commercial product. Now, they can be said to be everywhere.
A lot of people talk about the lithium-ion battery potential alternatives, but so far, there is no kind of battery can serve in this role. Substantial decline in production costs, enhance energy density and scale of production efficiency, meaning that it is still the best choice for many consumer electronic products.
In fact, Tesla has invested $ 5 billion, is being built in Nevada large lithium-ion battery factory Gigafactory, its size is very large, enough to let lithium battery production decreased by 30%. Even Apple is also poaching engineers from the lithium-ion battery manufacturers there to create their own R & D department. So it looks like the lithium-ion battery technology will flourish for some time.
Lithium-sulfur battery
when the solar aircraft first flight in 2008, on the use of lithium-sulfur (li-s) batteries. During the day, photovoltaic panels (photovoltaic panels) solar aircraft not only provides the ability to fly, and its rechargeable lithium-sulfur batteries, in order to maintain the momentum needed for night flight.Sion Power is engaged in one of the first lithium-sulfur battery research and development company that in 2010 the US government $ 5 million in funding, in 2012 the German chemical giant BASF's $ 50 million investment. Sion Power said, the energy density of lithium-sulfur batteries eventually reach 2.6 kwh per liter.
Supercapacitors
technically is not a super-capacitor battery, but only high-capacity capacitor. Advantages supercapacitor can be recharged in a few seconds, but the disadvantage is the large amount of energy can not be stored. They have been used for low-power devices, such as cordless electric screwdriver, which can be fully charged in 90 seconds, but a relatively small number of charge once the screws can be installed. In some cases, such devices may be just what we need.
Hydrogen fuel cell
driving a hydrogen fuel cell vehicles, feeling and driving a car almost fill up the petrol - but the car "tank" Riga is hydrogen. In a hydrogen fuel cell vehicle, the hydrogen combustion is not occurred, but a chemical reaction with oxygen, the reaction can be produced ion flow. The technology was invented in 1838, but has not been put into use until the National Aeronautics and Space Administration (NASA) will be used for space probes. The technique has been proposed for the automotive past, but Apple and other companies have tried to use the smart phone.
Remote wireless charging
wireless charging - the equipment on a special mat to charge it - is becoming more common, and the remote wireless charging is likely to make things happen to change radically.
Microsoft's scientists have been working to develop a piece of equipment, it found that the smart phone and using a focused beam is automatically charged for them. These devices can be installed in homes, offices and cafes and other places, in theory, you may no longer need to do it yourself for your cell phone charged.
