The Born Of New Lithium Ion Batteries
After many researches, new lithium-ion batteries that run 33% longer and have an
increased lifespan of 33% over traditional rechargeable batteries have been found finally. The Ultra-M 4.0 Ah batteries come with a variety of Metabo's cordless power tools, including the W18 LTX 4 1/2 angle grinder, the SB18 LTX 1/2 hammer drill and the BS18 LTX increasing productivity and lowering overall operation costs.
As with all
lithium ion batteries, the Ultra-M 4.0 Ah does not have a memory effect. It can be charged at the user's convenience without having to wait for the battery to totally discharge and does not lose any of its charging capability.
These lightweight, compact batteries feature Metabo's patented air-cooled charging technology that cools the battery pack to a level temperature during charging using guided air flow ducting.
This unique charging technology increases productivity by shortening the charging process and helps sustain the life of the battery by keeping individual cells cooler during the charging process.
The Ultra-M 4.0 Ah batteries feature Metabo's state-of-the-art cell monitoring system, Electronic Single Cell Protection (ESCP), that electronically monitors the individual cells during the charging and discharging process to prevent damage as well as to prolong battery life. The batteries and charger are covered by Metabo's three-year warranty; if they don't charge, they are replaced at no cost. Most batteries are made from lithium ion, and employ carbon as the anode. Other materials perform much better than carbon, and could substantially increase battery capacity. Tin anodes could potentially triple energy density, and silicon anodes might be able to hold 9 times as much charge as carbon. Such advances could lead to tablet computers and laptops that run for days before battery depletion, and to miniature, battery powered UAVs able to remain aloft for up to an hour. In an interview with Sander Olson for Next Big Future, Washington State University Professor Grant Norton discusses how battery technology could dramatically improve within the next several years, and how batteries with 9 times the energy density of current batteries could emerge within a decade.
The
lithium-ion battery has many beneficial features, but there is room for improvement. This is why researchers are examining new materials. So we have looked into the prospect of replacing carbon in the anode with tin, which could lead to a tripling of energy density. It would still be a lithium-ion battery, but it would have better performance.
They should be able hold 3x as much charge. But there are other materials, such as silicon, which could take the performance beyond that of tin. Replacing carbon with silicon should lead to 9x better energy storage.
There are also research labs who are using silicon as anodes. Silicon will definitely be a competitor down the road, when costs can be sufficiently reduced. But there are numerous technical issues that need to be surmounted in order to cost-effectively mass-produce silicon anodes. So that is probably a decade or more away. But a 9x improvement over commercial batteries is clearly worth investigating.
Since there are multiple versions of fuel cells out there, a direct comparison is difficult. In many applications, particularly where high energy-densities are needed, they are superior to batteries. There are non-trivial cost issues with fuel cells, and so I hesitate to say unequivocally that they are superior.
Within a decade, we could have batteries that offer 9x performance and longer lifetimes than current lithium-ion batteries, such as lithium polymer batteries, lithium ion carbon batteries,
cr2025 lithium batteries. So many of our clean energy initiatives absolutely depend on superior battery technology than we have now. If the 21st century is to be the century of green power, then we will need to develop much better battery technology than we have now.
