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 is 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,
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 rechargeable batteries 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 seawater.
In the outer third of this technology, there is one technology that needs to be considered – ultracapacitors. EEStor claims they have been able to find a ceramic ultracapacitor design using a barium-titanate powder which significantly increases the capacity of the ultracapacitor. Traditional Ultracapacitor can only store 1 / 25 capacity Li-Ion battery, despite having a 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.
