According to ZPower president and CEO Ross Dueber, the batteries can even be safely overcharged to allow for additional runtime.However, the batteries won't work in current products due to the difference in voltage and battery chemistry of silver-zinc batteries. Notebooks and cell phones will specifically need to be designed for this new type of batteries for optimal efficiency. Pricing details aren't available. Source: DailyTech.
ZPower batteries are composed of a composite polymer zinc anode, layered separator and a nano-particle silver cathode. Since the cells used in ZPower's batteries are water-based, they are as safe to use as traditional alkaline batteries.
The zinc and silver used in the batteries are also 95 percent recyclable. ZPower will have a program in place in which customers can recycle their used batteries and get reimbursed for the value of the silver and zinc recovered. Customers will receive a check or receive credit towards the purchase of new cells according to Dueber.
All is not well, however, with ZPower's batteries. Pre-production batteries are only good for about 100 cycles compared to around 300 cycles for lithium-ion batteries. ZPower hopes to increase this figure to 200 cycles by mid-2008 and to 300+ cycles by 2010.
