Is lithium battery inferior to dry battery?

"Why is a disposable dry battery so environmentally unfriendly, like remote control, Bluetooth mouse keyboard and other products? Why not being directly built in the battery, and then charge when the power is used again? Is it because of the cost?"

Believe to this problem also is to have a lot of net friend expresses doubt, dry battery is not convenient, still not environmental protection, why the science and technology of now developed to this kind of level, and remote control, Bluetooth mouse keyboard is like to be ignored, use dry battery all the time? In fact, no matter how this problem is circled, with cost cannot leave concern.

Why do we still use batteries for things like remote controls and Bluetooth mice?

A large share of well-known Bluetooth mouse and keyboard and remote control is in the use of dry cell, why won't the built-in battery without electricity, such as direct charge to use, when in fact the most important thing is that because of the mobile phone, remote control mouse and keyboard, Bluetooth and electric cars, and so on use of the other to refill the technical equipment of the biggest difference is that mouse and keyboard, Bluetooth remote control of the energy consumption is too small.

Usually, the battery management system in the equipment will judge the remaining electric quantity of the battery according to the change of voltage to prevent the battery from over-discharging. Over discharge is refers to the battery in the process of discharge, final over the battery over the battery discharge threshold, will cause the battery internal pressure increases, continue to discharge the battery anode of lithium ion migration to the number of the cathode is overmuch, cause the collapse of the anode material structure, reversible damaged, positive and negative active material inside the battery capacity is decreased obviously. The battery management system for phones and other rechargeable devices ensures that this doesn't happen during use, and that they don't start up when the battery reaches a threshold to avoid damaging battery capacity.

With mobile phone, remote control, Bluetooth mouse very little current, voltage drop slowly, by these few current normal voltage and current influence of voltage, by contrast, a battery protection circuit to produce more accurate decision, make the battery management system to produce protective effect, often has been discharge inside the battery power, the great damage loss for batteries, and it's easy to let this battery to become disposable batteries.

If the manufacturer wants to provide a built-in battery for the mouse and remote control, this battery is basically a branch of lithium battery no matter what type of battery it USES. Then, raising the alarm threshold of low voltage will increase the process and increase the cost of technology. A Bluetooth mouse in the use of dry battery and the use of dry battery price gap at least one-third more expensive, it will cause a lot of generation manufacturers in order to compete with competitors in the price war above the wind and choose to make dry battery equipment. As for the remote control itself is an accessory, the manufacturer will not want to make the high cost of the remote control to increase the cost of the whole product. It is the age of price war after all.

In fact, to sum up, the cost of Bluetooth mouse and remote control is relatively low, the selling price is relatively cheap, and the remote control is an accessory product. If rechargeable batteries are used, the cost will increase, which is not in the interest of the manufacturer. In other words, it is cost that limits technology. It is also because these devices are less iterative that today's remote controls still use dry batteries. In fact, to put it more simply, the use of dry batteries compared to lithium batteries, more simple and cheaper.
