Citation: Toshiba Introduces New 10 Year–Quick Charge Industrial Battery (2007, December 11) retrieved 18 August 2019 from https://phys.org/news/2007-12-toshiba-year-quick-industrial-battery.html Toshiba has developed a battery that can be recharged in five minutes with a lifespan of 10 years. Toshiba has trademarked the new accumulator, the SCiB. The new quick charge-Super Charge ion Battery will go to market in March, 2008. Initially, the SCiB distribution will focus on the industrial equipment sector. In practical use of the new SCiB its unique composition allows for 4.2 Ah, (ampere hours) on 10 cells for recharging by standard or alternative energy sources. The monitoring system within the battery controls voltage temperature, and cell balance adjustments. This safety precaution minimizes or eliminates the possibility of short circuits or explosions by ignition within the battery. In an industrial setting, the safety precautions features alone sell the product. The SCiB may be recharged in as little as five minutes time. The unique feature of the new product is that after 3,000 recharges the battery only lost less than 10 percent efficiency. In further company tests after 5,000 recharges the SCiB was still viable. This amounts to 10 years of continuous use for the SCiB. This feature reduces the need for battery waste management, by extending the use of the battery. The battery´s longevity and versatility in utilizing energy sources qualify it as a Green Technology. The standard or SCiB mode features extensive safety precaution for high power charges. The battery may be charged to 90 percent or more in five minutes. Other batteries do not have the same level of safety built-in that will allow heavy current charges, (50A). This feature suits the industrial setting in providing quick charges without the obvious hazards of fire and explosions. An additional feature of the SCiB is its ability to run at extremely cold temperatures. Toshiba warrants that the SCiB can work efficiently in minus 30 C which is minus 22 F. This is a welcomed attraction for many areas of the world where frigid temperatures are a factor. Toshiba has not released details on when it will be released to a broader sector of the market. In addition, the company has not indicated the various modifications they may be considering for future development. Super Charge ion Battery.

Most human evolution researchers agree that at some point in history, estimated to be about 5 million to 7 million years ago the chimpanzee and human like species proceeded on a different evolutionary path. The question DeSilva addresses is whether early man’s adaptation to full bipedalism involved a swift shedding of the ability to climb and swing from trees. DeSilva compared the great apes and early hominin ankle joint, the tibia and the talus in the foot. He discovered marked differences between the structure and capacity of these two skeletal fossils. DeSilva observed and filmed Uganda’s modern chimps tree climbing and tree swinging activity. He discovered that modern chimpanzees when pushing off from a tree branch flex their ankles, thereby raising their foot some 45 degrees. Modern man generally flexes his ankle only 15 to 20 degrees while walking and suffers injury if stretched any further. It goes without saying, there are certain super modern athletes who can flex the ankle without injury. In effect, DeSilva points to an important evolutionary divide, wherein early hominin may have foregone his natural tree climbing, ankle flexing capacity in order to walk upright. His examination of early hominin and the great ape indicates the evolutionary morphing took place very rapidly. His review of early hominin and the great ape demonstrate the ankle joint differences took place early in the evolutionary cycle. According to ScienceNow reporter Michael Baiter in his article, “Our Ancestors Were No Swingers”, David Begum, a paleoanthropologist at the University of Toronto in Canada points to early hominins ability to scramble up a tree for safety which would not have involved or required the full 45 degree ankle flex exhibited by modern chimpanzees. The DeSilva study agrees with its critics. He concludes that if early hominins included tree climbing as part of their survival skill set, they were performing it very differently than modern chimpanzees.

DeSilva an anthropologist at Worcester University in Massachusetts has published “Functional Morphology of the Ankle and the Likelihood of Climbing in Early Hominins,” in the peer-reviewed journal, Proceeding of the National Academies of Sciences of the USA current issue. The study includes data gathered by DeSilva in Uganda’s Kibale National Park of modern chimpanzee and comparisons of hominin fossil skeletal remains dating back some 4.12 million to 1.53 million years ago. The findings appear to show that if early hominins depended on tree climbing as part of their survival repertoire, they were performing it decidedly different from modern chimpanzee locomotor activity.
