Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
Although these processes are reversed during cell charge in secondary batteries, the positive electrode in these systems is still commonly, if somewhat inaccurately, referred to as the cathode, and the negative as the anode. Cathode active material in Lithium Ion battery are most likely metal oxides. Some of the common CAM are given below

Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Lead acid batteries are a type of rechargeable battery that primarily compete with lithium-ion and nickel-metal hydride batteries. They are known for their lower energy density, relatively high cost, and shorter lifespan compared to advanced battery technologies, yet they have advantages in cost, reliability, and recyclability.
The electrolyte in lead acid batteries serves as a medium that facilitates the movement of ions, allowing for the battery to generate electrical energy. It is crucial for the chemical reactions that occur during charging and discharging. The main roles of the electrolyte in lead acid batteries include:
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by starter motors.
Common materials include porous plastics like polyethylene and polypropylene. These materials are critical to the battery's safety and efficacy, as they prevent lead particles from coming into direct contact and causing malfunction. The casing of a lead acid battery usually consists of materials like polypropylene or PVC.

An easy way to fix it is to power down your computer, hold down the power button for 15 to 30 seconds, plug in the AC adapter, then start the computer. Disable Apps and Check Battery Usage in Windows 10.
Remember to have a look at your power cable. If it is too loose or disconnected, it's likely to meet the "power supply light on computer won't start" problem. First, make sure the cord is firmly connected to the PC and the outlet. Second, try unplugging and re-plugging the cord. If this action is not helpful, the cord itself may be the problem.
If your computer is still failing to start up after checking the power button and changing a different cable, it possibly has a power issue. Then, you can try another power source. All you need to do is to unplug the cord from the current power source and plug it into a working wall outlet.
It could be that the power up sequence requires a larger draw on the battery (like a car, for instance) and that either the pins are not making contact to start the machine or an issue like that is preventing the battery from sending enough power to start the device.
A faulty CMOS battery is a rarely noticed factor causing power supply light on, computer won't start. If the CMOS battery is old or broken, it may fail to offer enough power to the BIOS chip, which is responsible for the PC booting. Therefore, try removing and reseating the battery to see if it can make a difference to fixing the problem.
Sometimes unknown glitches can prevent the battery from charging. An easy way to fix it is to power down your computer, hold down the power button for 15 to 30 seconds, plug in the AC adapter, then start the computer. 9. Disable Apps and Check Battery Usage in Windows 10
All you need to do is to unplug the cord from the current power source and plug it into a working wall outlet. If it's your laptop not turning on but power light is on, ensure you plug the charger in and then begin to try a different power source. ▶ Fix 4. Check the Beeps
