Maybe it was the detailing in the battery casing or advertising costs we were paying for. The solution that conducts the current is the electrolyte, and it remains the core technology of batteries. The ubiquitous use of batteries in popular handheld devices such as mobile phones and electronic organizers is forcing manufacturers to produce batteries with long lifetimes. Developing new battery technologies that will make electronic devices significantly more energy-efficient is big business. Fortunately, portable-power chemists and engineers are rallying to solve the problem with new battery technologies and hardware.
Silver is too expensive and mercury is toxic.
Nonetheless, researchers have been ferreting out new combinations of elements that can produce more electrically potent chemical reactions, only to find that it takes years to tweak a new process and remove the bugs. It is the best selling rechargeable technology on the market. This can cause a significant problem for the battery management circuit, which is why Hewlett-Packard does not recommend rechargeables. Several companies have developed innovative lithium-based battery technology to address the demand for longer lasting batteries. The NiMH battery is the best selling power source for cellular phones.
