Week 1 Understanding Different Battery Chemistry
1 . Cell chemistry
| Cell type | Material | Material | chemical reactions |
| LCO | Lithoium cobalt oxide | 1. Carrbon (graphite or hard carbon) Anode 2. Sepeartor ( Aluminium & copper) 3. electrolyte |
*While discharging, negative electrodes give up electrons & gets oxidised *While charging, negative electrodes accepts electrons & gets reduced Or in another words during discharge . Positvely charged ions or cations move thoroghthe electrlyte towards postive electrode and negtively charged ions or anions move through the electrolyte towards the negative electrode |
| LMO | Lithium Magnese spinet | ||
| NCA | Lithium -cobalt-Aluminium | ||
| NMC | Lithium -Nickel - Magnese -cobalt | ||
| LFP | Lithium-iron phophate | ||
| LTO | Lithium titanate |
Question 2 : Cell characteristics
| Cell type | Material | characteristics |
| NCA | Lithium -cobalt-Aluminium | 1. High specific energy 2. High specific power 3. Saftey concerns 4. Medium perfomance 5. High life span 6. High cost |
| NMC | Lithium -Nickel - Magnese -cobalt | 1. High specific energy 2. Medum specific power 3. Saftey concerns 4. Medium perfomance 5. Medium life span 6. Medium cost |
| LMO | Lithium Magnese spinet | 1. High power density 2. Poor electrionic conductivity 3. Medium saftey 4. Low perfomance 5. Low life span 6. Medium cost |
| LFP | Lithium-iron phophate | 1. Low specific energy 2. Medum specific power 3. High saftey 4. Medum perfomance 5. HIgh life span 6. Medium cost |
| LTO | Lithium titanate | 1. High power density 2. Poor electrionic conductivity 3. High saftey 4. High perfomance 5. High life span 6. Very high cost |
