Zinc batteries are being developed, and lithium batteries will be replaced by zinc batteries?

Researchers at the Department of chemistry, NRL, have developed a new type of battery -- rechargeable zinc battery, which is much safer than lithium battery. And its research institute has already been banned on naval ships and other military platforms because of the flammability of lithium ion batteries.
The research points out that the capacity of rechargeable zinc battery is similar to that of Li ion battery, but it has lower cost, faster speed, smaller volume and lighter weight. It is expected to be applied to hybrid energy vehicles, electric vehicles, electric bicycles, even mobile phones and large-scale storage devices. Is the age of lithium ion batteries really coming to an end? Let's get to know the new zinc battery first.
Battery technology company in California, San Anselmo's (EnZinc) CEO Mitchell Bruce (Michael Burz) said that they are ready for testing and promotion of this technology, hope to be able to achieve good results.
Debra Rolison, head of the advanced electrochemical materials department at the US Naval Research Laboratory in Washington, Rowley, is also involved in the research of the zinc battery. He argues that the biggest weakness of lithium batteries is that it is easy to overheat or even fire and explode. The US Navy has been hoping to find a alternative to lithium battery technology to avoid potential hazards to servicemen and weapons by lithium battery instability. The fire risk of zinc battery is much less than that of lithium battery, and the unit volume and unit mass energy storage can not be lower than the lithium battery. In addition, zinc is much more than lithium on the earth and much cheaper. Therefore, the zinc battery is a promising next generation rechargeable battery.
However, for a long time, zinc battery is considered to be unrechargeable, because only after several rounds of charging, there will be conductive wires between the two electrodes of the zinc battery, which will lead to two pole short-circuit. This time, the US Navy research team found a way to inhibit the production of thin wires inside the battery, that is, making zinc anode into porous sponge structure. Thus, during the charge discharge of the battery, the current on the zinc anode will be more uniform, so the conductive filaments are difficult to produce.
