More and more attention devoted to this one component. Batteries are an important component of any electronic equipment. Of the various existing types commonly used today, NiMh, Li-Ion are the most widely used by various electronic products, including notebooks, digital cameras and various other gadgets. In recent years, Li-Ion main choice, because the choice of this material allows a smaller battery, discharge is smaller, longer battery life, larger capacity and lighter weight,
However, Li-Ion battery is not a “perfect”. Massive recall by several manufacturers of notebook batteries and a few years ago, showed that this material has sufficient characteristics “exploded”. In addition, the cost of production and quality control (so that similar problems do not happen again) makes Li-Ion batteries are not fit for use in hybrid vehicles – at least according to Toyota. Only a company car / electric motors that use Li-Ion battery – they also admitted that the cost (and weight) Li-Ion battery cover most of the cost of production. The cost of batteries for the Tesla Roadster is estimated at about U.S. 60,000, or half the price of the car.
Therefore, researchers around the world trying to find alternatives to replace the Li-Ion. New companies like A123 Systems rely on lithium iron phosphate, while Revolt managed to find a way to make rechargable battery from the zinc water (note: air, not water). Even large companies such as Energizer batteries should have been offering their water Zinc battery series next year (the sample has been available this year). Both products offer much higher power than the Li-Ion (3 to 4 times the power Li-Ion, with the weight and volume equivalent). The main difference between the two is the amount of recharge capacity and price. Zinc batteries offer a number of charge cycles water is lower than Li-Ion, but its production cost is only half the Li-Ion. Conversely, the cost of lithium iron phosphate battery production is estimated to be cheaper than Li-Ion.
After these two alternatives, a combination that is targeted by a lithium metal-water. Lithium metal-water is able to offer higher capacity than the lithium iron and zinc-air, but at the same time, lighter weight than zinc-air. PolyPlus has successfully created a prototype design for a lithium metal electrode so that the battery used water can be used even in the water and sea water.
In the outer third of this technology, there is one technology that need to be considered – ultracapacitors. EEStor claims they have been able to find a ceramic ultracapacitor design using a barium-titanate powder which significantly increase the capacity of ultracapacitor. Traditional Ultracapacitor can only store 1 / 25 capacity Li-Ion battery, despite having faster reaction – allowing much shorter replenishment. by EEStor, the products they can offer 2 times the power capacity Li-Ion. When the Li-Ion battery, lithium iron phosphate and zinc-air still require recharging time in hours, EEStor ultracapacitor can be charged in minutes.
