Product Parameter
Lithium-Ion Battery
A lithium-ion battery is a rechargeable energy storage device that uses lithium ions moving between positive and negative electrodes to store and release energy. It offers high energy density, long cycle life, and lightweight design. Widely used in electronics, electric vehicles, and energy storage systems, it requires built-in protection circuits for safety and stability. Common types include LFP (LiFePO4) for safety and longevity, and NMC for high energy density.
Advantages of Lithium-Ion Batteries
High Energy Density
Stores more energy per unit weight/volume than other rechargeable batteries, enabling compact and lightweight designs for devices like smartphones and EVs.
Long Cycle Life
Withstands hundreds to thousands of charge-discharge cycles while retaining significant capacity (e.g., typically 80% capacity after 500+ cycles).
Low Self-Discharge
Loses only 1-2% of charge per month when idle, far less than Ni-Cd or Ni-MH batteries, ensuring longer shelf life.
Fast Charging
Supports rapid charging capabilities (e.g., EVs reaching 80% charge in 30 minutes with advanced systems), enhancing convenience.
High Efficiency
Exhibits excellent charge-discharge efficiency (90-95%), minimizing energy loss during use.
Low Maintenance
No "memory effect" (unlike Ni-Cd batteries), eliminating the need for periodic full discharges to maintain capacity.
Environmentally Friendly
Contains no toxic heavy metals like cadmium or lead, and is recyclable, reducing ecological impact.
