Batteries Rechargeable (Secondary)

1. Overview

Rechargeable batteries (secondary batteries) are electrochemical energy storage devices that can be repeatedly charged and discharged through reversible chemical reactions. Unlike primary batteries, they form the backbone of modern energy storage systems, enabling portable electronics, electric vehicles (EVs), and renewable energy integration. Their ability to reduce long-term costs and environmental impact makes them critical in sustainable technology development.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Lithium-ion (Li-ion)High energy density (100-265 Wh/kg), low self-discharge, long cycle life (500-2000 cycles)Smartphones, EVs, laptops
Nickel-Metal Hydride (NiMH)Moderate energy density (60-120 Wh/kg), environmental friendliness, memory effect resistanceHybrid vehicles, digital cameras
Lead-AcidLow cost, high surge current capability, heavy weightAutomotive starters, backup power systems
Lithium Iron Phosphate (LiFePO4)Exceptional thermal stability, long lifespan (2000+ cycles), lower energy densityElectric buses, solar storage, marine applications

3. Structure and Composition

Typical rechargeable battery cells consist of:

  • Cathode: Lithium cobalt oxide (LiCoO2) in Li-ion, Nickel oxyhydroxide (NiOOH) in NiMH
  • Anode: Graphite (Li-ion), Hydrogen-absorbing alloy (NiMH)
  • Electrolyte: Lithium salt in organic solvent (Li-ion), Potassium hydroxide (NiMH)
  • Separator: Microporous polymer membrane preventing short circuits
  • Current Collectors: Copper (anode), Aluminum (cathode)

Cell designs include cylindrical (18650 format), prismatic, and pouch configurations with integrated protection circuits.

4. Key Technical Parameters

ParameterDescriptionImportance
Energy DensityWh/kg or Wh/LDetermines runtime and weight
Charge Cycle LifeNumber of full discharge/charge cyclesDictates longevity and cost-effectiveness
Internal ResistanceMeasured in milliohmsAffects power output and efficiency
Self-Discharge RateMonthly capacity loss percentageStorage performance indicator
Charging EfficiencyPercentage of energy retained during chargingImpacts operational costs

5. Application Fields

  • Consumer Electronics: Smartphones, tablets, wearables
  • Transportation: EVs (Tesla Model 3), Hybrid vehicles (Toyota Prius)
  • Renewable Energy: Solar+storage systems (Tesla Powerwall)
  • Industrial: Forklifts, uninterruptible power supplies (UPS)
  • Military/Aerospace: UAVs, satellites

6. Leading Manufacturers and Products

Samsung SDIINR18650-30QNickel Cobalt Manganese (NCM)
Exide TechnologiesChloride SLALead-Acid
LG ChemLGDBHE21865Lithium-ion Polymer

7. Selection Recommendations

Key considerations:

  • Energy Requirements: Calculate Wh needed for target runtime
  • Power Profile: Assess peak current demands (e.g., EV acceleration)
  • Environmental Conditions: Operating temperature range (-20 C to 60 C typical)
  • Cost Constraints: Balance upfront cost vs lifecycle value
  • Regulatory Compliance: UN38.3, IEC 62133 certifications

Example: Select LiFePO4 for solar storage systems requiring 5000+ cycles and wide temperature tolerance.

8. Industry Trends

  • Material Innovation: Silicon anodes (20%+ capacity increase), solid-state electrolytes
  • Fast Charging: 0-80% in 15 minutes (e.g., Tesla 4680 cells)
  • Recycling: EU Battery Passport regulations driving closed-loop systems
  • Market Growth: 12.6% CAGR projected through 2030 (Grand View Research)
  • AI Integration: Smart BMS (Battery Management Systems) optimizing charge cycles
