When designing lithium batteries, it is very important to correctly calculate the reasonable ratio of cathode and anode capacity. The preferred solution for battery system design is to use excess cathode and anode capacity limit (N/P ratio < 1.0), which can alleviate the decomposition of the electrolyte.
The discharge rate of a lithium battery is used to indicate the ratio of the battery''s charging and discharging current ( Maximum Discharge Current = C * Capacity). For example, for a battery with a capacity of 1000mAh, if the discharge rate is 1C, then the discharge current is 1000mA; if it is 10C, the discharge current is 10000mA.
This comparison underscores the importance of selecting a battery chemistry based on the specific requirements of the application, balancing performance, cost, and safety considerations.

Li-ion batteries are finding new applications in markets where they are replacing older lead-acid technology and there is a drive to convert products that previously used internal combustion engines (ICE) to electric power.
The capacity ratio between the negative and positive electrodes (N/P ratio) is a simple but important factor in designing high-performance and safe lithium-ion batteries. However, existing research on N/P ratios focuses mainly on the experimental phenomena of various N/P ratios. Detailed theoretical analysis and physical explanations are yet to be investigated. Here,
