History
The history of the battery is also the history of practical electric current. Before chemical cells, experimenters could produce static electricity, but they did not have a convenient source of steady current. Batteries made sustained experiments in electrochemistry, electromagnetism, telegraphy, lighting, motors, communications, and portable electronics possible.
- 1780s — Galvani and “animal electricity.” Luigi Galvani observed muscular movement when metals contacted prepared frog tissue. Alessandro Volta argued that the important source was the contact of unlike materials, leading him toward a chemical source of current.
- 1799–1800 — Voltaic pile. Alessandro Volta stacked pairs of zinc and copper discs separated by electrolyte-soaked material. He announced the device in 1800. It was the first continuous, reproducible chemical source of electric current.
- 1836 — Daniell cell. John Frederic Daniell separated the chemical processes into two electrolyte regions. His cell supplied a steadier current and reduced the rapid loss of performance that troubled early voltaic cells. Daniell cells became important in telegraphy.
- 1859 — Rechargeable lead-acid battery. Gaston Planté developed the first practical rechargeable battery. Lead-acid chemistry remains widely used where low cost, ruggedness, and high surge current matter, including vehicle starting and standby power.
- 1866 — Leclanché cell. Georges Leclanché introduced a zinc and manganese-dioxide cell that was well suited to intermittent loads such as bells and signaling equipment. Later paste-electrolyte versions led to the familiar dry cell.
- 1880s — Commercial dry cells. Sealing the electrolyte into a moist paste made cells more portable and less prone to spilling. Dry zinc-carbon cells became practical power sources for flashlights, radios, and many consumer products.
- 1899 — Nickel-cadmium battery. Waldemar Jungner developed a rechargeable alkaline cell using nickel and cadmium electrodes. Nickel-cadmium batteries later became known for high current capability and long service life, though cadmium toxicity greatly restricted their use.
- Mid-20th century — Alkaline primary cells. Improved manganese-dioxide and zinc cells using an alkaline electrolyte provided longer life and better high-current performance than ordinary zinc-carbon cells.
- Late 20th century — Nickel-metal hydride. Nickel-metal hydride cells replaced cadmium with a hydrogen-storing alloy, providing useful rechargeable capacity for consumer electronics and early hybrid vehicles.
- 1970s–1991 — Lithium-ion development. M. Stanley Whittingham demonstrated an intercalation cathode in the 1970s. John Goodenough developed a higher-voltage cobalt-oxide cathode in 1980. Akira Yoshino produced the first commercially viable lithium-ion design in 1985, and lithium-ion batteries entered the market in 1991.
Why each step mattered
Early cells proved that chemistry could produce continuous current. The Daniell cell improved steadiness. Lead-acid chemistry introduced practical rechargeability. The Leclanché and dry cells made batteries portable and inexpensive. Nickel-based cells improved repeated cycling, while lithium-ion chemistry greatly increased the energy available for a given weight and volume.
Battery development is rarely the work of one isolated inventor. Practical products require advances in active materials, electrolytes, separators, sealing, manufacturing, charging, electronic protection, safety testing, and quality control. The modern battery is therefore both a chemical device and a manufactured electrical system.
The word “battery”
Benjamin Franklin used the word battery for a group of electrical devices connected together, borrowing a military term for a group of artillery pieces. In strict electrical usage, one electrochemical unit is a cell and a group of cells is a battery. Everyday language now commonly uses “battery” for either one cell or several.
