Toshiba Corporation has announced a breakthrough in lithium-ion batteries that makes long recharge times a thing of the past. The company's new battery can recharge 80% of a battery's energy capacity in close to one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today. The battery also has a long life cycle, losing only 1% of capacity after 1,000 cycles of discharging and recharging, and can operate at very low temperatures

Techtronic Industries Co. Ltd. of Hong Kong developed the V28™. This 28-volt battery delivers increased power and up to twice the run time of traditional 18-volt models, yet the battery weighs slightly less. This means the introduction of new tools like the world's first cordless band saw powerful enough for every day professional use. Containing no cadmium, the lithium ion battery has built-in fuel gauge that tells users how much run time is available. In addition, this battery is equipped with built-in Performance Optimizing Circuit to provide consistent, fade-free power throughout discharge cycle to ensure job power consistency.

Panasonic Batteries has its new Digital Xtreme Power batteries with oxyride technology, designed to last twice as long as regular alkaline batteries, according to the company. They utilize a combination of newly developed materials for the cathode (plus side): Oxy Nickel Hydroxide and new technologically developed manganese dioxide and graphite. According to Panasonic, that means the batteries will yield three times as many snapshots with a digital camera, with a shorter flash recovery time.

Trends

Battery Council International recently completed part of an ongoing project to determine the trends of battery development (among other things) and how manufacturers will adapt. There are a few interesting items to note from their research:

Various forms of lithium batteries are emerging on the market. Although there are concerns about their flammability, many manufacturers are pushing industry standards by pre-qualifying these battery makers. The reason for this trend is simple - lithium is the lightest metal, which results in a high specific charge. For example, it takes 3.85g of lead to produce 1 amp for 1 hour while it only takes 0.26 grams of lithium to produce the same. One type of lithium battery is only 2.5mm. Lithium also produces a higher voltage and therefore, a higher energy density. Lithium is also more eco-friendly than lead or cadmium. These characteristics seem to fit right in line with market trends and many electronics manufacturers have noticed.
